Re: Multiple Supervisors 6509 Chassis; Native IOS [7:51654]
Well, one good reason to have 2 sups in each chassis is that if one Sup does die, sure HSRP will kick in and the other 6500 will be the gateway, but only for the devices connected to the switch that's still up all of the devices on the 6500 that had the Sup die will be down and down hard (unless there is some way that Layer 2 functions continue even tho the sup died which I can't imagine). With a second Sup, at least after about 2 minutes, all of those devices will have connectivity restored as well. Mike W. Larry Letterman wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: polycom Video Unit [7:49882]
Depends on the model, but usually you'll see traffic all into either 128Kbps, 384kbps, 768Kbps or 1.5Mbps We have a Polycom unit that has ISDN and a LAN port, but if you telnet to it's IP on the LAN you get a status page showing H.323 is disabled, so we can't use it on the LAN (at least without a software update or something). But if you Polycam can video conference over IP with it's ethernet port, then it should be standard H.323. I can't recall the ports right off the top of my head, but I'm thinking somewhere in the 2600+ range (I've seen other units that use 2000-2063), but don't quote me on that It's regular IP unicast traffic, but (depending on the model) it's possible to do a multicast streaming presentation (usually you'll use the multicast when you want to broadcast a presentation or video, etc to many viewer but most times you're not in a conference where there are many senders and receivers) HTH, Mike Steven A.

Re: polycom Video Unit [7:49882]
John Neiberger wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I suppose it depends on the unit but ours mainly use unicast to the Cisco MCU. As far as I know they use standard H.323. The downside if you're using an MCU is that the PolyComm units have a lot of different codecs available that might not be known by the MCU. For example, the Cisco MCU can only do G.711 audio, but if you let two video units speak directly to each other they use G.726 ( I think. Maybe it's G.722?) and it sounds much better. That brings up an interesting question tho unless the MCU is converting between codecs for end stations that might want to use different codecs, must the MCU understand the codec or would it simply act as a relay startion for that data. (i.e. if two end-stations are using a codec that they understand but the MCU doesn't, would it be a problem since the MCU would merely forward the unknown (to it) audio data to the other end station). The Cisco MCU supports many more codecs than G.711 including the popular G.729 codec (which gives roughly G.711 quality with an 8:1 compression). The G.722 (you were right.. it's G.722, not G.726) that covers from 50-6900Hz instead of 50-3900Hz as most narrowband codecs do. So if you're trying to play more high fidelity sound, you may want to use that. I haven't seen many units that support this codec though (but I have by no means seen tons of units, just a few). However, if the audio you're trasmitting is human speech, the G.722 isn't going to gain you much in terms of sound quality since it would be preserving an additional frequency range that's not used alot by human speech. Does anyone have any input or experience with how and/or when the MCU codec support comes into play? I would think that if the endpoints are at the same datarate and using the same audio/video codecs, the MCU would just be a bounce point and the actual codecs in the MCU wouldn't be utilized Just a theory tho..

Re: VoIP Bandwidth Calculation you wil have to consider two [7:49388]
That 24Kbps would make sense as G.729 should compress the voice to 8Kbps for a unidirectional voice signal, so 16Kbps for bi-directional 24Kbps should be plenty for overhead and a bi-directional voice stream. However, if you want you could use G.729b (or G.729ab if you happen to be using medium complexity) to enable Voice Activation Detection (VAD) and that can reduce your overall bandwidth utilization by up to 40% by not sending data when a party is not talking (and throw on some comfort noise while using VAD). That kicks azz, as that would lower the bandwidth needed for a G.729b (or ab) call to roughly 14.4Kbps, so you could (in theory) jam up to four simultaneous (close-to-toll-quality) calls over a single 64Kbps line.

Re: DHCP Server on Multiple VLANs [7:49403]
That's exactly what he should do Winston Shaw wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Hello Don, I think you could set up DHCP scopes on a server and use the ip helper address command to direct dhcp discover broadcasts from your clients. The router should place its own sub-interface address in the packet and send it to the DHCP server. The server should then pick from the corresponding scope depending on the router IP address. I know of at least one server which does that but I do not want to mention it here. Winston V. Shaw CCIE(#7991) -Original Message- From: Don Pezet [mailto:[EMAIL PROTECTED]] Sent: Monday, July 22, 2002 1:15 PM To: [EMAIL PROTECTED] Subject: DHCP Server on Multiple VLANs [7:49403] Hey guys, I have a Cisco 3620 connected to a 2948G-L3 which in turn provides layer three services to a cluster of 3548XLs. I have 9 operating VLANs and have been trying to work out a scenario for DHCP in my environment. Right now, we assign static IPs in all 9 vlans because we do not want to provide seperate DHCP servers for each. If we could find a way to get one server to provide DHCP to all the VLANs then we could implement it. The trick is, each VLAN is a different subnet. I had heard that if you use the 3620 as a DHCP server, create subinterfaces on a FE port using ISL and assign IP addresses appropriately, and create multiple DHCP pools, then the router would issues IPs from pools that matched the interface it drew the request from. However, when I try this it just issues IPs from the first pool until it is full and then moves to the next. Is there a way to make sure the router assigns correct IPs on the correct sub-interfaces? Is there a 3rd party DHCP server that would do this better? Let me do a sample config to show what I tried. Each network has a network printer at .200 (don't ask) and a router sub-interface at .1 except the 10.10.10.0 network which has reserved IPs through 100, but still a router interface at .1 Here's the Cisco 3620 DHCP portion of the config: ! ip dhcp excluded-address 10.10.10.1 10.10.10.100 ip dhcp excluded-address 192.168.1.1 ip dhcp excluded-address 192.168.1.200 ip dhcp excluded-address 192.168.2.1 ip dhcp excluded-address 192.168.2.200 ip dhcp excluded-address 192.168.3.1 ip dhcp excluded-address 192.168.3.200 ip dhcp excluded-address 192.168.4.1 ip dhcp excluded-address 192.168.4.200 ip dhcp excluded-address 192.168.5.1 ip dhcp excluded-address 192.168.5.200 ip dhcp excluded-address 192.168.6.1 ip dhcp excluded-address 192.168.6.200 ip dhcp excluded-address 192.168.7.1 ip dhcp excluded-address 192.168.7.200 ip dhcp excluded-address 192.168.8.1 ip dhcp excluded-address 192.168.8.200 ! ip dhcp pool Vlan1 network 10.10.10.0 /24 dns-server 4.2.2.1 default-router 10.10.10.1 ! ip dhcp pool Vlan10 network 192.168.1.0 /24 dns-server 4.2.2.1 default-router 192.168.1.1 ! ip dhcp pool Vlan20 network 192.168.2.0 /24 dns-server 4.2.2.1 default-router 192.168.2.1 ! ip dhcp pool Vlan30 network 192.168.3.0 /24 dns-server 4.2.2.1 default-router 192.168.3.1 ! ip dhcp pool Vlan40 network 192.168.4.0 /24 dns-server 4.2.2.1 default-router 192.168.4.1 ! ip dhcp pool Vlan50 network 192.168.5.0 /24 dns-server 4.2.2.1 default-router 192.168.5.1 ! ip dhcp pool Vlan60 network 192.168.6.0 /24 dns-server 4.2.2.1 default-router 192.168.6.1 ! ip dhcp pool Vlan70 network 192.168.7.0 /24 dns-server 4.2.2.1 default-router 192.168.7.1 ! ip dhcp pool Vlan80 network 192.168.8.0 /24 dns-server 4.2.2.1 default-router 192.168.8.1 ! interface FastEthernet1/0 description connected to Private Network no ip address duplex auto speed auto ! interface FastEthernet1/0.1 encapsulation isl 1 ip address 10.10.10.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.10 encapsulation isl 10 ip address 192.168.1.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.20 encapsulation isl 20 ip address 192.168.2.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.30 encapsulation isl 30 ip address 192.168.3.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.40 encapsulation isl 40 ip address 192.168.4.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.50 encapsulation isl 50 ip address 192.168.5.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.60 encapsulation isl 60 ip address 192.168.6.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.70 encapsulation isl 70 ip address 192.168.7.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.80 encapsulation isl 80 ip address 192.168.8.1 255.255.255.0 no ip redirects !

Re: Collision Detecting [7:48830]
Comments inline. wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... If we run 10 or 100 Half Duplex to a switch ... Is there a chance of a collision occuring? Yes, definitely. Anytime you run half-duplex there is a possibility of collisions. If we then run 10 or 100 Full Duplex to a switch ... Is there a chance of a collision occuring, besides late collisions, etc. If you are running full-duplex, there is no possibility for collisions. From what I have read (or remember to have read): When we run in full duplex we have seperate TX/RX wire pairs i.e the TX pair on one side is wired to the RX pair on the other side and vice versa... hence there should be no collisions and that's why there is no collision detection mechanism in 100MB ... Right? You are correct that there is a dedicated TX and RX pair that are crosswired, and you are correct that is why there isn't collision detection.. but it has nothing to do with 100Mbps. When you put a switchport or NIC in full-duplex mode, the collision detection circuitry is bypassed, since it's not needed. However, this isn't a function of speed. But the reason I ask this, is that yesterday I had a problem with a NIC, and the options I had listed in the NIC Device Driver Software was this: 100Mb Half Duplex. I thought 100Mb could only run in full duplex? However when we run Half Duplex, the TX/RX occurs on then same wire pair so how does 100Mb Half Duplex work if there is no collision detection mechanism for 100Mb? Yeah basically, you're making the mistake of assuming 100Mbps = Full Duplex, and it does not. Speed and duplex are independant of each other. Mike W.

Re: Class C summarization question [7:48367]
Wow. According to my binary math, 4 bits = 16 combinations. 1 bit = 2 combinations (2^1 = 2) 2 bits = 4 combinations (2^2 = 4) 3 bits = 8 combinations (2^3 = 8) 4 bits = 16 combinations (2^4 = 16) Now. when converting from binary to decimal, the 4th bit (from the right) has a (decimal) value of 8 (2^[4-1]), but of course when you add the values of the bits from 4 down, you get 8+4+2+1 = 15 (thus giving 16 combinations, 0 through 15) (Too all that have read my posts in the past, now you know why I bitch up a storm when I hear someone encourage someone else to memorize subnetting charts and bitswapping charts instead of taking an hour and learning how binary actually works... geez) Mike W. - Original Message - From: Andy Hoang To: Michael L.

Re: Strange 6500/IPX Issue!! HELP!! [7:47951]
Your diagram is correct as far as connections go. Most of the Novell servers are connected to the 5513, but all are in VLAN 1. The 5513 RSM does all IPX routing for all VLANs. All VLANs are trunked between all switches. There aren't any IPX routes on either of the 6509s as IPX routing isn't enabled on them. As far as IPX is concerned, the 6509s are just L2 switches.

Re: Strange 6500/IPX Issue!! HELP!! [7:47951]
Wes, Thanks for your reply. As you can imagine I've been through the ringer so far with this one =) We checked all of the trunks for native VLAN, speed, duplex, etc... All checks out. This is also supported by the fact that IP works fine (all IP routing for VLAN1 is handled by the RSM in the 5513, which means anything plugged into 6509A or 6509B that leaves the IP subnet must travel those trunk links to hit the RSM and get routed. One interesting note: In an attempt to find out anything new, I took a Dell desktop with integrated NIC, etc (my test machines and the machines having the problem so far have been IBM 300PL with integrated NIC), and when the Dell is connected to 6509B (the one with the problem) it boots and gets the Novell login, which automatically points to the hardware or the image on that IBM. However, that same IBM, when connected to 6509A works fine, which kinda discounts that theory. I'm going crazy here!! Another interesting thing to note: If I connect the PC (the IBM) to a 2900, then connect the 2900 to 6509B, the client still doesn't receive the Novell login. However, if I connect the PC to a hub and connect the hub to 6509B then the PC boots and gets the Novell login everytime. I gotta be missing something.. I watched the 'sho mac int fas' closely and upon booting the IBM's MAC address isn't seen by the switch for 12-15 seconds after you see Starting Windows 95. The MAC address on the Dell becomes visible within about 3 seconds after Starting Windows 95. However I'm sure part of that can be attributed to the fact the IBM is a 200MHz -vs- 900MHz on the Dell (and the Dell I'm sure has newer faster drives, etc) But everytime I start to form a theory about something to do with the PC, my co-worker goes Yeah, but it works on the other 6509 and everytime I form a theory that it could be something wrong with 6509B he goes, Yeah, but the Dell works on it.. I can't win!!! Thanks again to all who have replied... Mike W. Wes wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Michael, Shot in the dark - I've seen very strange issues like this with trunk mismatches. You've probably got a trunk between the two switches. Make sure your native VLANs match, make sure that every VLAN permitted on the trunk is permitted on both sides. On a similar vein, all trunk ports should have similar characteristics (I go with 100, full, desirable trunking, desirable channeling; regardless, just make sure it's the same both sides) Also, if you've got links bundled, try bringing down one of the links for a bit, then try the other(s). Switches load balance via MACs, if you've got a uni-directional link or something, packets from the same machine will usually transit the same wire every time - physical port/cable problems might appear to be associated with only certain machines because of this. Best guess for now. Good luck! --Wes Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=47967t=47951 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: VOIP dialer-peer question [7:47976]
Voice Gurus: I'm going to take a stab on this because I just went through some of this myself (with 2610s but hey same deal)... feel free to point out my mistakes If you are doing an EM trunk between the two PBXs (with the VoIP link acting as the router), then the dialing information you configure is local to those VoIP peers and doesn't affect the actual dial digits that are passed between the two PBXs. So as long as their PBXs have dialing plans that are setup to talk to each other, the digits you use to establish the trunk calls between the VoIP peer routers is arbitrary. For instance, here would be configs for each end of a VoIP trunk: Side A controller T1 1/0 framing esf linecode b8zs cablelength short 133 ds0-group 1 timeslots 1-24 type em-wink-start ! interface Ethernet0/0 ip address 10.1.1.1 255.255.255.0 full-duplex ! voice-port 1/0:1 output attenuation 3 connection trunk ! dial-peer cor custom ! dial-peer voice 1 voip destination-pattern session target ipv4:10.1.2.1 dtmf-relay cisco-rtp codec g729br8 ! dial-peer voice 2 pots destination-pattern 9998 port 1/0:1 Side B controller T1 1/0 framing esf linecode b8zs cablelength short 133 ds0-group 1 timeslots 1-24 type em-wink-start ! interface Ethernet0/0 ip address 10.1.2.1 255.255.255.0 full-duplex ! voice-port 1/0:1 output attenuation 3 connection trunk 9998 answer-mode ! dial-peer cor custom ! dial-peer voice 1 voip destination-pattern 9998 session target ipv4:10.1.1.1 dtmf-relay cisco-rtp codec g729br8 ! dial-peer voice 2 pots destination-pattern port 1/0:1 Basically, on a given router you: 1. Assign the DS0s to a DS0 group 2. Under the Voice port (created when you create the DS0 group), configure 'connection trunk' with phone number of the other end (something you make up, not part of the PBX dial-plan) 3. Create a 'voip' dial peer where you give the phone number (from step 2) and the IP of the peer (and I suggest using DTMF Relay if you're using compression) 4. Create a second dial peer that is 'pots' that maps the incoming phone number to the local voice-port Note: Cisco recommends putting answer-mode on one end of the trunk links. Note: Cisco does *not* recommend or support putting all 24 DS0s into a single DS0 group unless you are using IOS 12.2T or higher (some problem with individual DS0s getting hung). I have a sample config I created that makes 24 separate DS0 groups each mapped with their own phone number and pots peer. If you need I can forward cuz it will sure save alot of typing. HTH, Mike W.

Re: VOIP dialer-peer question [7:47976]
My previous post and this URL are strictly for permanent voip trunks between PBXs. Sorry... I meant to include an URL.. One thing I did NOT like about this example tho, is that they are doing as I mentioned and configured a separate DS0 group for every DS0 and therefore they end up with multiple 'pots' dial-peers and voice ports (one for each DS0 group). The result of this is that when they have a config line like destination-pattern 111. is misleading because it appears your accepting the dial digits from the PBX, but you're not you're only matching the dial-digits that you configured locally. http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120 t/120t7/t1_vo_t6.htm#xtocid1960937 Mike W.

Re: Dual Link redundancy .... [7:47854]
Huh? Why would you need VLAN trunking to utilize Etherchannel? They're two independant technologies (that can be combined if you wish). We have Etherchannel configured between many switches that aren't trunk links (i.e. only carrying VLAN1). (and it would also be a pain to configure an EtherChannel connection to a router if you only want that router in a single VLAN if you had to trunk) From Cisco's website: (watch for wrap) http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sft_6_1/configgd /channel.htm#xtocid141809 EtherChannels can be configured as trunks. After a channel has been formed, configuring any port in the channel as a trunk applies the configuration to all ports in the channel. Identically configured trunk ports can be configured as an EtherChannel. If you configure the EtherChannel as a trunk, configure the same trunk mode on all the ports in the EtherChannel. Configuring ports in an EtherChannel in different trunk modes can have unexpected results. If you needed trunking for Etherchannel to work, then why would the above say After a channel has been formed . . . and If you configure EtherChannel as a trunk . . .? Mike W.

(passing score was 45) The beta was very difficult, so much so that I forked up the $300 and took the current written a week or so later (and passed)... So I could look at this as $300 wasted, or not. I choose not. If anything, I look at it as $50 well spent, just to keep me up on what changes are going to be made to the written.

Re: HSRP [7:47177]
This isn't quite right. See comments below. Kim Graham wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... This brings up a question. I understand that after the initial hi I will be handling your requests please use me as your destination mac address. (Router talking to client). But what happens when the initial router fails and HSRP kicks in? After an unreachable, would ClientA send out an arp or would RouterB initiate the arping to re-establish connections to any client that was using RouterA after it noticed that RouterA was not responding? Scenario: ClientA - RouterA/B(HSRP) -- ClientB ClientA sends a packet to ClientB ClientA talks to the Virtual RouterA/B -- RouterA/B sends to ClientB RouterA/B tells ClientA -- RouterA will be handling your requests. Router A never tells Client A that Router A will be handling your requests. As you mentioned, Client A talks to the Virtual Router via the Virtual IP address which it ARPs to find the Virtual MAC. Client A never knows which of the HSRP routers is intercepting and processing it's requests When Client A sends a frame to the Virtual MAC to go out of it's gateway, both Router A and Router B hear the packet, but only the HSRP Active router will process it. So if, the janitor steps in and unplugs Router A, then after Router B misses enough Hello packets from Router A, it declares itself the Active HSRP router for that HSRP group, and at that point it starts to process the information sent to the Virtual IP/Virtual MAC. This is all transparent to the end clients, Client A in this example. So as far as Client A knows, it's still sending traffic to the Virtual IP via the Virtual MAC address it has in its ARP cache.

Re: serial interface down/down or up/down [7:47101]
According to CCIE exam materials, the *only* time the serial will show down/down is when there is NO serial cable or a bad serial cable connected. So even if you have a misconfigured framing method, you should at least see up/down. Mike W. Bob Timmons wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I can't say I've ever seen a down/up condition. Up/Down perhaps. I'm sure there are exceptions, but it's my belief that the router doesn't care about encoding, but rather a layer-1 connection to the dce/dte device. If the router can 'talk' to the device on the other end of the cable, you should get an up/x condition, where x would depend on the csu/dsu condition of the line. I don't have a csu handy, otherwise I'd check that right now. I can do that tomorrow morning (10:30 pm est here), but you may have an answer prior to that... Hi Priscilla, I have actually had this scenario (multiple times), but due to the Telco's misconfiguration. Specifically we were expecting b8zs/esf. Unfortunately I can't confirm which was configured incorrectly, but I can confirm that going through all of the different combinations available at the router you will get all combinations on the serial interface (up/up, down/up and down/down). I can also confirm, you will not establish connectivity, regardless. I believe either b8zs/esf or sf/ami are the only valid combinations. At least that is all I've ever worked with. Hope this helps, -TV Priscilla Oppenheimer wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Hi Group Study, While writing some questions for a practice test, I found myself questioning what I thought was the right answer. Here's the scenario: A Cisco router serial interface is correctly connected with a good V.35 cable to the data port on the DSU side of a CSU/DSU. The CSU/DSU has been misconfigured for the framing method (SF instead of ESF). The framing doesn't match what the provider is using. (The question refers to a CSU/DSU that is external to the router, not one that is built into the router.) Will the Cisco router serial interface be down/down or up/down? And, would the answer be any different if the question has to do with misconfiguring the encoding (AMI versus B8ZS)? If you have real-world experience with this, that would help.

Re: Combining T1's into one pipe [7:46942]
If you're running a dynamic routing protocol (i.e. RIP, IGRP, EIGRP, or OSPF), they should see the two T1s as equal cost paths and automatically do per-destination load balancing (if you're running CEF, then that can be per-packet, at least with EIGRP, but I would suspect the same no matter now the route was learned). But you need to disable fast-switching because that will only switch out of a single interface and not load balance. If you don't want per-destination load balancing or can't run CEF to allow per-packet, you can run Multilink PPP and bundle the two T1's into a single channel. Either way, if one of the T1s, goes down, the other will still carry the traffic (at the single T1 bandwidth) and it's automatic. MultilinkPPP, however, is more processor intensive than letting the routing protocl handle it (although if you have to disable fast-switching and don't have CEF (i.e. enable process switching)) then that'll be pretty CPU intensive anyway) Here's an article about letting the router load balancing automatically: http://www.cisco.com/warp/public/105/46.html Here's an page about Multilink PPP: (watch for URL wrap) http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/dial ts_c/dtsprt4/dcdppp.htm I'd like to see the page on Cisco's site that says this process is complex, because the first method I spoke of it automatic and the Multilink PPP method is a piece of cake, even if you've never done it before. HTH, Mike W. Doug Korell wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I have two point to point T1's that I'm thinking about combining (known as NxT1).

Is anyone else doing this and if so, it is worth it? If you have any Cisco links that describe the setup process, I would appreciate posting them. I was also wondering if one of the T1's goes down, will it bring the whole pipe down or will your bandwith just decrease?

Re: OT - Mega, Kilo etc [7:46940]
Interesting you ask.. I've had a similar conversation and my thoughts were always the same... (that each power of 10 was equated to 2^10 more than the previous), but it seems to vary alot. I've found that with memory (RAM), they stick to the hard core binary metric system where 1K always = 1024, 1M = 1024 * 1024 and 1 Gig = 1024 * 1024 * 1024. But with network bandwidth it seems that 1K = 1000, 1M = 1,000,000 and 1G = 1,000,000,000 (good old metric, not binary metric). Hard drives (strangely enough) usually use 1024 for K, but then 1M = 1024 * 1000 and Gig = 1024 * 1000 * 1000.. (then again I've seen some hard drives that specifically say 1Megabyte = 1,000,000, etc..) It's a strange thing that happens... we just have to live with it =) Mike W. wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... This is not specifically related to Cisco, but is a networking question. I was having a mild argument yesterday with a PC/server type guy who was very irate at an ISP for using gigabyte to mean 1000 Megabytes instead of 1024 Megabytes. He appeared to think that throughout the IT industry, K always means 2 ^ 10, M always means 2 ^ 20, etc etc. I pointed out that this is not always the case (64kbps = 64000 bps, for example), and haven't yet had a reply (I actually agree with him that the ISP is using the wrong definition, but I can see why they are). However, it got me curious. After a quick squizz through various sources, I couldn't find any that define the prefixes for networking usage. www.whatis.com has an interesting page on the prefixes, which basically backs up what I thought - roughly, storage (memory sizes etc) usually uses prefixes calculated in powers of two, while data transfer usually uses prefixes calculated in powers of ten. But is this codified anywhere? For example, do the ethernet standards define 10 Mbps, or 1 Gbps (Yes, I know about the IEEE site, but the standards don't seem to be currently downloadable)?

Re: Not on;y is TR going... [7:46391]
Actually, if you're running Native IOS on your 6500s (which many HUGE corporations are now doing because of how redundancy is handled and besides it's like having a 280+port router =), then there is really a minimal differents in the 6500 and 3550 commands. They're both IOS, so no diff.. As far as Content Switching Module. I gotta say. who cares? Knowing L2/L3 switching is the most important in setting up a network and in the lab not Layer 7 switching.. (although it does appear that Content Networking is covered as part of the CCIE Communications Services) Not trying to dog you out or anything, but I think the 3550 will make an excellent low-cost replacement for 5000s in the CCIE lab (instead of the extra cost of throwing in a 6509 or something... that's a bit overkill for a lab rack). And a 3550 will FINALLY force people to start using IOS commands for L2 switching configuration and hopefully CatOS will completely die as a result of this change in the lab.

Re: Difference between cat 6000 6500 and 3550 [7:46478]
Are they using 6x00 switches in the lab? I thought they were still using Cat5000s and therefore the CatOS and Set/Show/Clear commands. If that is still the case, you wouldn't want to use a 3550 as it uses IOS (config t, etc). I know the 6000s and 6500s you can use in Hybrid (CatOS) or Native (IOS) mode... I believe if you don't specify when you order, you'll get Hybrid by default.. Just be sure that you're in hybrid and it should be very much like being on a Cat5000. If the 6000 happens to be in Native, you can convert to Hybrid by following these instructions: http://www.cisco.com/warp/public/473/80.shtml HTH, Mike W.

Re: Difference between stacking and interconnecting switches [7:46081]
Although I've not used 'stacking' I've heard and read of it a small bit. It seems it's makes multiple switches appear as a single switch as far as managing the equipment. However, performance-wise, is there any gain to 'stacking' switches as opposed to simply interconnecting them.

Re: Using Catalyst 2950 switch [7:46062]
IMHO, you should always force the speed and duplex on both the switch and the end device. Autodetect can work find if both sides are set to autodetect, but if one side is set to a particular duplex and speed and the other is auto, you'll almost surely run into to problems (the least likely problem is if one port is set to 10-Half, as autodetect *should* properly detect this setting 100% of the time). Most of the mismatches that happen aren't speed, but duplex mismatches. I had an excellent web page that gave great detail on why this happens, but here's an good page from Cisco about this topic: http://www.cisco.com/warp/public/473/46.html HTH, Mike W.

Re: CCIP - who is doing this one? [7:45166]
I'm thinking that was probably a fluke or something. IMO, the BSCI was virtually identical to BSCN with the addition of IS-IS. Although I had some study materials for ACRC, I never took it (because it changed to BSCN), so I can't compare the two. I might dig up my ACRC practice tests and stuff, because I can't really see the BSCN being *far* less detailed than ACRC. from what I've read and see people say, there were only minor differences in the ACRC and BSCN But I also heard from people that the BCMSN was a bit more difficult than the CLSC (apparently the CLSC didn't cover multicast, IGMP, CGMP, MLS, etc) But again, I didn't take it, so my comparison could be way off... A good friend of mine did CCNP then CCIE. He finished CCIE while I was working on CCNP. He did the old style CCNP (ACRC, CLSC, etc). I did the new style CCNP (BSCN, BCMSN, etc). We compared 'notes' so to speak, and I would say the CCNP of now is any less challenging than the previous version. If anything perhaps a bit more difficult because it encompassed a bit more.. Either way my point was that if you've taken BSCN/BSCI (and passed) then you should already have a more in-depth knowledge than needed on CCIE written Mike W. wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I think the depth of knowledge on each subject will not be touched by that required for CCNP/CCIE... Hmmph. I have done the BSCI, but none of the other exams for the CCIP (I had the option of doing a freebie exam at Networkers, which is the only reason I did it). The level of routing protocol knowledge required for BSCI was very shallow, in my opinion. I haven't done the BSCN, either (I did ACRC a few years ago), so I don't know how the BSCI compares to BSCN, but the BSCI required *far* less detailed knowledge than the ACRC did. I hope that the BSCN requires more routing knowledge than the BSCI, because if not, I reckon the CCNP is going towards a cornflakes cert (or maybe I just struck the easy BSCI questions).

Re: Fast Ether Channel [7:45271]
I appreciate your information, Joseph. I guess my question was more toward the types of interfaces that will run etherchannel. i.e. if you're knocking the speed down on a FastEthernet interface to 10Mbps, it's still a FastEthernet interface, not Ethernet interface. One of the requirements for an etherchannel bundle is that all of the ports (interfaces) in the bundle all be matching speed/duplex. So it would make sense that you could knock 100Mbps interfaces down to 10Mbps (as long as they all match) and it still work. But are they any Ethernet interfaces (not Fast- or Gig-Ethernet) on any Cisco devices that support Etherchannel. I'm thinking there's not, but that's not to say there's not some switch/router out there that may violate this Cisco rule of thumb (being you can only do EtherChannel on Fast- or Gig-Ethernet) Mike W.

Re: why copy tftp run retain some old config ??? [7:45323]
Try a write erase before loading from TFTP I'm *sure* someone will correct me if I'm wrong (hehe) but I remember thinking that when you copy from TFTP or Flash to running config, it's the same as if you typed the commands in yourself (whatever commands are in the file), so when you copy from TFTP to running-config, you'll get a mixture of the two..

Re: Doyle on Lab Rats [7:44611]
nrf wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Well, I don't know if it's a waste of time. Consider this. There might be some newbie guys who were all gung-ho about grabbing a bunch of certs because they believed that by doing so they would just be handed a super-kick-ass job (no doubt some training school told them so). Now perhaps after reading these threads they may be getting a whole new appreciation for exactly what certs can and cannot do for them, and they may be rethinking their whole strategy, and perhaps even stop studying and instead concentrate on building their experience first. Actually, in the case you pointed out, if someone stops studying to concentrate on building experience first, then I believe you have done those people a great disservice. Many people use certifications as a foot in the door into a network career from other careers. We've agreed (many times) that just because one gets a certifications that their not entitled to a high level job with lots of money, but at the same time, a certification can be the difference between getting that foot in the door or not. If ones goal is to use certifications to prove a certain level of knowledge and abilities in an attempt to get into the field, then steering them in the direction of get experience first, then worry about certs later is exactly the opposite of what could potentially help them the most. So you could say that in these cases, these threads have not only not wasted people's time, they have actually saved people's time. Then of course, there are those guys who've already made up their minds about what they want to do and don't want to hear what anybody else has to say (I call them the certification religion people). But I'd like to think that some people do indeed maintain an open mind about these kinds of things. I am by no means a certification religion person. You speak of maintaining an open mind but from your comments, it's easy to see that your blinders are on as tightly as can be. You only see things from your point-of-view, and no amount of logical reasoning will convince you that your point-of-view isnt' always the best for other people. You fail to realize and admit that there are many different ways that certifications can help and can be used in ones career path. You assume that by encouraging one to work on experience and worry about certs later is the best thing someone can do, but many times it's not. I knew 9 months before we moved to a much bigger town that I wanted to change over into networking. So given my experience in desktop/server admin, etc and knowledge of networking, I saw that getting CCNA/DA and working on CCNP would look much better to an employer looking to hire someone into an entry level Cisco job than just my experience alone. In that case the certification was a sign to the employer that I understand what the OSI is... understand the difference between switches and routers understand how to log into a router and get into enable mode and do basic commands. That's exactly what the certification is meant for, and that's exactly how I used it. Now, I'm much more into networking, have been doing it a while, and am studying for CCIE lab... At this point, I'm not doing a cert for anyone else but me. To help improve me... So it's all, again, just a matter of perspective. Mike W.

Re: Doyle on Lab Rats [7:44611]
nrf wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Aha. Here is the fundamental difference between you and me. The fact is, certifications are not really an effective foot-in-the-door, contrary to popular belief. Yeah yeah, would-be flamers, I just got your attention, didn't I? I can already hear you guys reaching for your keyboards. But hear me out. The fact is, certs are indeed useful to get publicly posted jobs. You know, the jobs where you have to send out a resume which then gets parsed through HR who look for certain keywords. Those keywords are often technologies, but are also often certs. It is indeed the case that to get your 'foot-in-the-door' in these kinds of jobs, you need present the proper keywords, which often means presenting the right kind of certs. However, consider this. CNN and other reputable news organization have stated that over 90% of all available jobs are never posted publicly, especially nowadays, and especially in the tech industry. Study after study has shown that far and away the most common and preferred method for companies to find people is through employee referral. Surely you've heard the phrase It's not what you know, it's who you know. I don't agree (surprise surprise) with most of what was said above. Although I would love more concrete information other than they say 90% of all jobs..., I would agree that many jobs, especially in the tech industry, don't always make it to the public. However, I would have to believe that by the public it means a company doesn't directly solicit candidates, yet instead goes to a consulting/contract firm. Fact is, most companies have policies that say they *have* to post a job publicly for 'x' amount of time, so it VERY doubtful that jobs that aren't posted to the public are full-time hires (even when the jobs don't make it to the public, they're usually restricted to hiring an internal candidate unless the jobs is posted publicly).. but instead most contract jobs that could potentially turn into a full-time employment gig (even if they have to post a job for x amount of time just to satisfy requirements). Furthermore, in those situations (I'm claiming is a large part of that 90%) where the jobs are filled by consulting firms, those companies are the ones that DO get to charge more for people with those certs. those are the companies there those certs ARE the foot in the door (speaking of contract firms), I've noticed that regardless of certs or experience, it seems many more places are doing a 6-month right-to-hire because it's so hard to really tell from a resume, certs, experience, or even an interview if someone really knows what they're doing. So a 6-month trial period usually is plenty for them to see if the person has the mettle or not. In fact, surely you're seen all those books and all those websites that tell people how to find jobs. What's the first piece of advice that they always give? The first thing they always say is use your network. It's not get proper certs or type up a really good resume. Those things are like 5th or 6th on the list, but never first. The first thing is always use your network. Why is that? I think this speaks to the importance of having the proper contacts. It truly is far and away the most effective way to find work. Where did get some experience fall into that list? I guess that's not as important at using your network.. Seems to be it would be tho... And the simple fact is, when you get jobs this way, certs become a relatively minor consideration. When the boss comes down and asks his people whether they know somebody with such-and-such skill, your colleague generally doesn't care whether you hold a cert or whatever - he either thinks you're good (because he's worked with you before and he knows that you're good) and will therefore recommend you, or he doesn't and he won't. And if you do get recommended by your colleague, you have effectively leapfrogged HR and their whole keyword-parsing step. Employees usually don't want to professionally embarrass themselves by bringing in somebody that they don't think is good, so the fact that you did get brought in for an interview is already a powerful quality-control mechanism that the boss can rely upon. Is it a perfect quality-control mechanism? No of course not, there is no perfect mechanism. But it's been shown to be a lot more reliable than anything else, and certainly more reliable than certs are. The proof of this is simple - companies continue to rely on such references for over 90% of their positions, which probably means that it's highly effective, otherwise they should have stopped doing things this way by now. Personally, I've worked way too many places that worked on the buddy system (i.e. company that ends up hiring a friend of a friend just because they're friends instead of hiring a perfectly good candidate).

Re: Bridge and switch [7:44649]
First let me say that I was looking for a book to recommend to a friend, and I picked up this same book in the store and thumbed through I actually happen to stop on the part where it talked about how a switch (bridge) builds a routing table etc... I put the book down, pointed at it, and told my friend Don't by this book! I am appalled at what passes for techincal books (I guess I'm more sensitive about networking topics). but in the technical field, one must be careful about the terms they use because they can mean different things. packet -vs- frame, etc. Cisco calls the mac table a content addressable memory table. without spending more time than I have at the moment, I can't find a history on CCO as to why they do this. Here is some info I found on CAM... basically, you can use the data to find itself in memory (as opposed to having to know it's address in memory).. (all of the following info is from various web pages found through Google) Content-Addressable Memory (CAM): In this information-handling model, each possible piece of information has one and only one possible storage location. The data is its own key. It is important to differentiate CAM from a hash key or traditional index. With conventional indexing schemes the data content is used with a hash or index to produce the address location of the data. The address has no real or direct relationship with the information contained in the data. With CAM, the data describes its own storage location. This also means all like data will always be found close together in the physical data structure. There is a direct relationship between the information in the data and its location in the physical data store. In a symbolic system information is stored in an external mechanism. In the example of the computer it is stored in files on the disks. As the information has been encoded in some form of file system in order to retrieve that information one must know the index system of the files. In other words, data can only be accessed by certain attributes. In a connectionist system the data is stored in the activation pattern of the units. Hence, if a processing unit receives excitatory input from one of its connections, each of its other connections will either be excited or inhibited. If these connections represent the attributes of the data then the data may be recalled by any one of its attributes, not just those that are part of an indexing system. As these connections represent the content of the data, this type of memory is called content addressable memory. This type of memory has the advantage of allowing greater flexibility of recall and is more robust. You can compare CAM to the inverse of RAM. When read, RAM produces the data for a given address. Conversely, CAM produces an address for a given data word. When searching for data within a RAM block, the search is performed serially. Thus, finding a particular data word can take many cycles. CAM searches all addresses in parallel and produces the address storing a particular word. You can use CAM for any application requiring high-speed searches, such as networking, communications, data compression, and cache management. Mike W.

One small quibble (heheh. don't you expect this from me by now =) Although they do essentially refer to the same thing (a table of MAC addresses) (I know you know this, Priscilla, I'm just pointing out for others), the table of MAC addresses kept by a switch (in Cisco switches, I can't speak for other vendors) is stored in a type of memory, CAM memory, which is different than RAM and operates using a different mechanism (see my other recent post in this thread).. so, although we commonly refer to it as the CAM table (and as good Cisco network people we should cuz that's what Cisco calls it) we're really referring to is the table of MAC addresses that happen to be stored in CAM memory..
