Importance: High We have upgraded the router to IOS 12.1.2T from 12.1.1aT1. The remote site uses DLSw and IP to connect to the AS400. Some LAN users can ping he AS400, but others can not. All related LAN configs are correct. A trace from the router hits the destination, but from the workstation, it goes across the WAN to the main router, but then times out. The funny thing here is that if you ping the remote workstation that does not work from the AS400 directly, you get a reply and then the user can work and then ping the AS400 himself. I have checked the routes on the AS400 and all is ok -default route to the routers ethernet port. The only change is the software upgrade, some work was done on the AS400 and the firewall was rebuilt. I believe the issue to be with the AS400.

RE: Slow Speed in 2900 Switches, Pls Help!!
If you are using fast Ethernet cards on those five PCs, your effective network bandwidth when you connect the PCs to the 2900 switch, should be 100MBps, otherwise 10MBps if you're using ordinary Ethernet cards. VLAN or Spanning tree should really not be the problem with your switch as you did not indicate if you're using VLAN/spanning tree on the other switches. But you may want to configure the new switch to boot straight to packet forwarding mode (by pass all other switch modes) by following this procedures at each port interface configuration mode: * Spanningtree portfast. -Original Message- From: Chee Tong Sim [mailto:[EMAIL PROTECTED]] Sent: Monday, July 03, 2000 7:52 AM To: [EMAIL PROTECTED] Subject:Slow Speed in 2900 Switches, Pls Help!! Dear friends, I have a few questions to ask: 1) Our company Network are running at 100M speed. Now if I connect a 10M speed 3com hub to one of the ports in cisco 2900 switches (100M speed) in the company network, and I connect 5 pc to the 3com hub, so, the network speed of PC is 10M divided by 5= 2M each or 10M each? 2) As the users complain about the speed, my boss asked me to use the brand new 2900 switch (100M speed) to replace the 3com hub. So I connect 2900 switch to 2900 switch that in company network, and connect 5 Pcs to the 2900 switch, so the speed of PC should be 100M each or 100M devided by 5= 20M? 3) But user still complain about the speed, I use the ftp function to check the speed and found the speed is only 150kb/sec= 0.15M only. I suspect because the switches that I used is a brand new switch, I havent configure VLAN and spanning tree protocol on the new switch to block to packet broadcase, so the speed is slow. If this is the case, can I consult you, how to configure VLAN and spanning tree on the new switches? Can anyone teach me?

RE: Pre-sales People
Hi guys, I am a pre-sales engineer and here are some considerations: 1) Due to the increasing pressure of competition in the telecom market , I don't think over-sized solutions have a chance to be sold. Did you buy the catalyst 6000 or did you go for another solution? One company can always conpare offers. 2) Maybe with your field experience you can help me: sometimes we put twice the amount of flash memory in order to be able to download a second version of the IOS remotely (for managed routers) so that we do not have ot send an engineer on site for maintenance, which is unpractical and not cost-effective. You also have to count with future needs. 3) In pre-sales, we do not have the time nor the opportunity to dowload an IOS in order to check its size. We just have the recommanded Flash memory amount of cisco. If there is a table with the exact size of every IOS version please let me know.

Re: Fw: Can anybody suggest a solution ??
Rajan, You can try giving 2 static routes. One for primary link(VSAT link) and other static route for the Dial Backup. one static route will be for the primary link and the other static route with higher metric(Adm. distance) will be for Dial backup. By doing this, you don't need to make any changes in the Local Lan as well as in the router, just you need to put one static route in the router for dial backup with higher metric.

The image is not too large for the amount of FLASH. The boot ROM's are of the newest model 11.0's. I installed new RAM, but I've not reached RAM operations @ this point in a 2500 (verifying what has just been installed into FLASH)... Any leads would be greatly appreciated... Thanks !!! Phil
Re: Layer 3 switching vs. Layer 4 switching?
Francis, The process you have described looks more like "load-balancing"/"load-sharing" - Cisco LocalDirector supports that kind of traffic management. It seems that Layer4 switches do a bit difeerent thing (though mosty of them do load-balancing). We use FoundryNetworks Layer 4 switches in some of our implementatios for redirecting traffic to the WebFilter/cach engine. The switch is able to redirect packets on per-tcp-port basis. For example we have configured ours to redirect all http requests to the WebCache engines and let everything else through RGRDS, Evgeny ""Arigo, Francis"" <[EMAIL PROTECTED]> wrote in message 304545310AD0D3118F9900600897AD9A07743B@GALILEO">news:304545310AD0D3118F9900600897AD9A07743B@GALILEO... > We use an Alteon Web Switch that uses "layer 4 switching".

RE: how to configure VLAN on 2900 switch-how about full duplex and spanning tree
Hi Chee Tong, With your current "show run" below, you're only running one vlan1 on your catalyst 2924. By default, the catalyst 2924 comes with one VLAN1. By adding another VLAN2 in your switch, you can reduce broadcasts on your network. Here is an example of placing port fastethernet0/6 on VLAN2: conf t int fastethernet0/2 switchport access vlan 2 And if you want to enable spanning-tree, first do this to see if it's already enabled on the switch: sh span If it shows that it's "disabled", then you can do this to enable it: conf t spanning Hope it'll help you.

Re: Static Routing or Route Maps
The only problem with HSRP is that it can not detect link failure,as its purpose is to create router hardware redundancy. Plus, if routers are not on the same Ethernet segment HSRP will not work. So the configuration can look like that: a) routers are on the same Ethernet segment HSRP + floating static routes(or any IGP between two routers - RIP for example) HSRP Ip address is the default gateway for the internal routers/workstations Every router has statically defined default pointing to the ISP and other default with greater AD pointing to the neighbor REAL (Not HSRP) address. In this case if the router itself fails - HSRP will take care of the traffic, if link fails - router will insert floating static route in to the routeing table an forward traffic to another router. b) routers are in different locations - No HSRP, so no hardware redundancy only floating static routes. RGRDS, Evgeny ""Michael L. Williams"" <[EMAIL PROTECTED]> wrote in message 8joa3u$mgm$[EMAIL PROTECTED]">news:8joa3u$mgm$[EMAIL PROTECTED]... It seems to me using HSRP would be the best thing to do. That way, not only do the two routers act as redundant links for each other, they can load balance across them. Mike W.

Greetings, I have a customer that has two routers, each with links to ISPs. The links are statically routed. Using default routes in each router. They would like to have one link switch over to the other if one fails and when it comes up switch back. Is there a way to do this using static routing still (maybe floating static routes) or can I use route-maps OR will I have to configure a routing protocol? Thank you for your assistance.

Re: Pre-sales People
Hmmm kinda a little lost on the TCO logic here .. , A local TFTP server would be cheaper than the double flash cost and would give you a place to store configs also.] If the flash hoses you still can use the router and in some of the smaller machines it's single bank flash , so if the flash is hosed without a tftp server setup you have no backup at all -- Maybe with your field experience you can help me: sometimes we put twice the amount of flash memory in order to be able to download a second version of the IOS remotely (for managed routers) so that we do not have ot send an engineer on site for maintenance, which is unpractical and not cost-effective. You also have to count with future needs.

Re: how to configure VLAN on 2900 switch-how about full duplex and spanning tree
Hi Geoffrey, I believe Chee Tong was asking about vlan's in a catalyst 2924 model. The syntax you showed down below is probably for configuring a high end cat55xx or 65xx.

MC3810
Hi, I've got an MC3810 in stock, and I need to hook up a customer G.703 both sides (my 7513 the other side). On my MC3810 I've got an MFT module, so I'd like to run my link over that port. At a glance - and presently w/o having had console on the box - I'd go controller e1 0 clock source x mode yyy etc. Now, what's the interface name under which I may configure IP on the WAN side ? (The only other interface I want to use is the Ethernet one, for LAN side.) mh ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: how to configure VLAN on 2900 switch-how about full duplex an d spanning tree
Hi Luan I do not agree with you. They do exist, infact I use it on mine. It is very strange that the VLAN is not defined in the configuration mode, but that is the way it is. also, to see them you have to go in the vlan database, and type show.

A Bug in debug NAT ?
Hello World, Question 1 I was debugging NAT on a cisco 2501 running IOS 12.0(6) and tried to filter the output of "debug ip nat", as I usually do with other debug output, with the command #debug ip nat 10 The access-list 10 exists and it works. Always I used debug with access-list I got a confirmation like "IP packet debugging is on for access list 10" after entering the command. With the command above get a simple confirmation like "IP NAT debugging is on", no mention of access-list. Is this a bug? May my access-list be wrong? Question 2 On debugging NAT yet, I got the following output: 2w4d: NAT: i: tcp (172.16.2.1, 10008) -> (192.168.1.31, 23) [56131] 2w4d: NAT: ipnat_allocate_port: wanted 10008 got 10008 2w4d: NAT: o: tcp (192.168.1.31, 23) -> (200.189.5.21, 10008) [44840] What means "ipnat_allocate_port: wanted 10008 got 10008" ? -- [EMAIL PROTECTED] Engenheiro de Redes.

Re: file can't be deleted on 3640
When you just issue "delete file" command -IOS does not actually delete file - it marks file as deleted and hides its name (see example below - deleted file test_file_to_delete) , so you can undelete it later, These hidden files can consume quite a lot of memory if you do not watch for them. The other problem that if you copy another file into the flash, it is being written AFTER last byte of the "deleted" file, so you end up having "black holes" in your flash. The only way (at least the only way I know about with 5300 and 3600) to get rid of them is to "erase flash". you can see your hidden files with "dir /all" cwas-access#dir Directory of flash:/ 1 -rw- 7575284c5300-is-mz.121-1a.T1.bin 2 -rw- 392241mica-modem-pw.2.7.1.0.bin 16777216 bytes total (8799356 bytes free) cwas-access#dir /all Directory of flash:/ 1 -rw- 7575284c5300-is-mz.121-1a.T1.bin 2 -rw- 392241mica-modem-pw.2.7.1.0.bin 3 -rw- 10137[test_file_to_delete] 16777216 bytes total (8799356 bytes free) RGRDS, Evgeny ""Palis Michael"" <[EMAIL PROTECTED]> wrote in message 00e901bfe4de$3e65e100$[EMAIL PROTECTED]">news:00e901bfe4de$3e65e100$[EMAIL PROTECTED]... > I tried it on my AS5300 and it works > > I issued the command delete flash: and the file was deleted > without any problem > > > - Original Message - > From: Evgeny Babanin <[EMAIL PROTECTED]> > Newsgroups: groupstudy.cisco > To: <[EMAIL PROTECTED]> > Sent: Monday, July 03, 2000 1:48 PM > Subject: Re: file can't be deleted on 3640 > > > > I had the same problem (btw 5300 is the same)- You have to erase flash > > before copying new file. > > > > RGRDS, > > Evgeny > > "Jim Bond" <[EMAIL PROTECTED]> wrote in message > > [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > > Hello, > > > > > > I copied IOS file to flash memory but got checksum > > > error.

Re: Checksum Error @ Copy TFTP FLASH
Ive run into the same issue...it usually means I have some bad flash in the router. How many sticks are you using (2) or (1). It has nothing to do with RAM nor bootroms. It is strictly a FLASH issue (at least from my experience and what Ive seen). Where are you downloading the image from?

Verifying checksum... invalid (expected 0x555, computed 0x7688) Any Ideas... I have swapped FLASH sticks & this did not change the outcome. These are Cisco FLASH sticks (not a compatibility issue).

Re: Pre-sales People
Laurent, response to 1): Over-sized solutions can be sold VERY easily. I see it happen ALL the time! 2): twice the amount of flash??? uh...okay you need to start buying all of your gear from me!!! :) 3): Time or opportunity??? you dont have to actually download the code to see the amount of DRAM/FLASH needed. it shows it to you before you download. it doesn't take that long and it could save your customers lots of $$$. You have plenty of opportunity, it's just called LAZINESS!!! It's really not that hard to determine the amount of FLASH/DRAM needed. If you are worried about future releases of code, it's not a bad idea to bump it up a little (little being the key word). I usually go off of 12.0(7)t..

Yippeeeeee!
Finally attained my CCNP/CCDP status. Thanks to all on the group for answering most of my questions (and ridiculing some of my answers - hell we all have to learn...) I intend to study towards my CVOICE specialisation and then take the CCIE drake late this year. Looking to comlete the CCIE lab towards the late half of next year. For those that will invariably ask the order of my exams was as such... CCNA 1.0 ACRC (took it 3 times, passed on the third go - its hard) CIT CCDA 1.0 BCRAN (from 2.0 track) CID BCMSN (from 2.0 track) This makes me a newly minted CCNP/DP 1.0. I can now finally have my life back after being at the books for 53 weeks (from start to where I am now - you're never actually finished). Does anyone know what is in the CCNP/DP kit you get from Cisco? I was told you get a silver gong and a posh vertificate. Can anyone confirm this? Now for a nice holiday in the sun (without a Cisco book). Regards from London.

Re: CID/CCDP Stories
I think the questions in the exam where there is more than one correct answer are there for a reason. In real life you often have many ways to tackle a problem. All of them will work, however one of them is the most correct (and hence best way). The exam simply reflects this. I thought the exam was OK. I felt there was a lot of emphasis on desktop protocols. The only gripe I have is that some of the design pricipals they quote are now 'old fashioned' As such I suspect this exam will be replaced soon (no beta exam is availablable so it is going to be around for another 12 months at least). Sorry to hear you didn't pass it. Better luck next time.

RE: CID/CCDP Stories
I agree with you some what woody. I passed the CID but there were some questions that any of the choices would do the job and judging which one was better than the other was not too objective. Congratulations on your new certifications.

In real life you often have many ways to tackle a problem. All of them will work, however one of them is the most correct (and hence best way). The exam simply reflects this. I thought the exam was OK. I felt there was a lot of emphasis on desktop protocols. The only gripe I have is that some of the design pricipals they quote are now 'old fashioned' As such I suspect this exam will be replaced soon (no beta exam is availablable so it is going to be around for another 12 months at least).

2 questions for lab setup
I have been watching this list for a while and appreciate all the good info. It helped me pass the CCNA 2 exam by a comfortable margin. Thank you all. I have 2 lab setup questions. I need to get cables or BB60 to RJ45 adapters for reverse telnet for a 2523 router and am wondering where to get these. Second question is since the routers I have are token ring, can you go direct from a token ring NIC to the token ring port on the router or do you need to have a MAU. I have searched the archives and have not found these answers. Thanks in advance for your assistance. ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Messed up lab.
I may have misunderstood your router configs and your original design, but it looked like you have r1e0 connected to r2e0, r1s0 to r2s0, and r1s1 to r2s1. If this isn't the case, then never mind, ignore what I said! Regardless, you should start with connecting one link only and get it working the way you think it should. Once you get a single link working, it might be educational to start adding the other links and see how it affects your routing tables. You could also try doing this with different routing protocols to see if things behave any differently. > On 3 Jul 2000 00:39:25 -0400, [EMAIL PROTECTED] (John Neiberger) wrote: > > >Another issue, which would make things fun to play with, is the fact that > >you have three links between the same two routers. > > Sorry, I don't follow you. > Could you show the parameters that indicate the three links?

Congratulations Keith, I bet you feel great now.

Anyway(s), I only just got my CCNA 2.0 down 1.5 months ago so it'll be a while before I wake my neighbors up again :-) Regarding putting the letters after your name: I have started doing that 10% because I'm kind of proud of it :-) - BUT, 90% because I have experienced that many times when I communicate with sales people or technical support, they cut the crap a get straight to the point.

Re: Spanning Tree
Title: Spanning Tree This is an extremely cut version but here goes: The first step of Spanning Tree is to Elect the Root Bridge. Second step is that every Not Root Bridge must slect one Root port. The third step is where loop prevention comes in, electing designated ports. Every segment in a bridged network has one Designated Port. Root and designated ports forward traffic, non designated block traffic. Every active port on the root bridge is a designated port. Hope that's clear, Rick.

RE: BGP - 1 DS3, 4 backup T1s, 1 ISP
I have a nearly identical setup to what you're proposing except that I use the T1's daily along with the DS3 and I'm multihomed to two providers. It makes for some interesting tweaking but in the end it works quite well. Our average web site load time used to be in the 5-6 second range but now with the addition of the Localdirectors and BGP/multihoming our site load times average close to .5 seconds but occasionally bounce up to 2-3 seconds if we get some high-latency from one of the providers. I'm getting ready to switch to two DS3's here in a few weeks which will simplify things a bit and add much needed bandwidth. Anyway, I'll paste my config in here after I try to answer your questions. My disclaimer is that I still haven't had the time to become 'proficient' with BGP but my config works. :) a. One thing I found was I was much better off to have the ISP send a default route along with everything else and then weight it on my side. I never got what I considered to be a satisfactory solution when I tried to do it with static default routes. If you have the ISP send default routes then you can pretty much guarantee that everything will be dynamic. I had a couple situations where the BGP session went active but the links were fine and data wouldn't switch over to the other links. (dynamic=good) b. This strategy works well for me although you may want to find out where those 4 T1's are homed to. Definately make sure they're not on the same router as the DS3 and, although it'll close some of your load *balancing* prospects I prefer to have the T1's split between different routers as well. (all the redundant links don't do very well if the router that they home to crashesI had the 'opportunity' to learn that one as well) c. Using the T1's for every day traffic is up do you. However, since you'll be using BGP (and I guess even without BGP) any other person who happens to be on the same router that you have a T1 on will always go through the T1 because it's the shortest path. d. You'll have to worry about some of that but maybe not all. Your ISP should be able to help you get through any sticky areas. e. Ummm, I dunno...I'm open to suggestion :) I'm partial to using the route-cache on links with that much bandwidth but I'd welcome a more experienced answer as well. f. Another router shouldn't be required unless you feel the need for hardware redundancy as well. I'm currently using a 4700M for mine which is underpowered but I should be replacing that with a 7206 in a couple weeks. The limitation on the 4700 was memory and backplane speed...it seemed to have plenty leftover horsepower for the situation I put it in. Even with high bandwidth utilization the processor stayed at a very reasonable level. If it'll help, I'll forward a copy of my 7206 config when I get that ready.

Re: Spanning Tree
h A Root Bridge election is one function: determine which bridge in a collection of bridges on a LAN and for multiple inter-connected LANS will be the Root... The Designated Bridge election has another, different function: determine which bridge, as you noted, has the least cost path TO the Root Bridge. This notion of having a designated bridge precludes the possibility of having simultaneously active bridges that are acting in parallel to each other between two LANs. Each election process is triggered anew with topology deltas, of course, which is why the STA is a dynamic algorithm. Does this explanation respond to both of your questions? =8^) R/ Rainman "Deloso, Elmer G." wrote: Hi, all.

Switch backplace capacity - how much do you need?
Got another discussion question before I start work this morning ( no 4 day holiday for me :-< ) sort of a continuation of the Brad Ellis discussion about the SE over-engineering solutions for customers. Cisco of late is starting to talk about backplane capacity, and in particular expandable backplane capacity in some of their switches. So the question I have revolves around backplane capacity and "oversubscription" of the backplane on a switch. For example, if I have a Cat 3524 in the closet, and pop in cards to permit me 24 ports of 100 mbs full duplex, under what circumstances might I be concerned about "oversubscription". If I indeed had 24 devices plugged in, theoretically I could be pumping 4.8 gigs of data simultaneously ( less a little for interframe gaps, and other overhead kinds of things ) that puts me a theoretical 5 times oversubscription of this guy's backplane capacity. On the other hand, seems to me that if I were popping that much data simultaneously from my 24 devices I would have other problems. Even that proverbial high speed database / transaction / e-commerce server is not going to be running full tilt in and out all the time. Let alone user stations, no matter how much radio they listen to, or how many avi's or CBT videos they are watching. Those stream one way, recall. So... what kinds of things do you consider when provisioning or recommending? How would you approach this as a design issue?

Re: Switch backplace capacity - how much do you need?
I've wondered about this myself. Consider the Catalyst 4006 as an example. It has a 60 Gbps backplane. Yes, you read that correctly...SIXTY gigabits per second...in a chassis that can hold five modules plus a supervisor module. Do we really *need* that much? My guess is no, we do not need quite that much. however, nowadays I would pick the switch with the higher backplane if I had the bucks to get it. It's nice to know that what's under the hood can handle anything we throw at it. Another example: we are going to be purchasing a 6509 with 256 Gbps backplane. Why? Because we can. No other reason. Never in a million years will we need that much capacity on this particular switch, especially since we'll initially only have five modules in it. But we'll have plenty of room for growth and it's one less thing to worry about. Besides, I'm a speed demon and as long as it's someone else's money (my employer's) then I want the biggest, fastest, coolest stuff around. Now, if it were MY money, that's another story. I'd be a little more realistic about my needs. No one is going to be running every port, full duplex, at max capacity. It will never happen, and if it does then you have much greater problems on your hands than just the backplane capacity of your switch.

Re: Motorola & Cisco Frame Relay
If you mean directly connecting Cisco and Motorola equipment using frame relay, we had that configuration running successfully at 90 locations for quite a while. We had a Motorola FRAD connected directly to a serial port. In that case we made the router play DCE (frame-relay intf-type dce) and used ansi lmi (frame-relay lmi-type ansi). I don't remember it being necessary in our configuration, but if you're having encapsulation problems, try using ietf encapsulation (encapsulation frame-relay ietf). Good luck!

CCDA (CCDP) 1.0 and 2.0
Has anyone yet heard when the present CCDA (and for that matter CCDP) exams are to be retired? Cisco now lists the exams as CCDA (or CCDP) 1.0 and 2.0 but how soon are they going to jump. Is it worth persuing the CCNP track and coming back to the CCDA/CCDP when things have clarified. From the changes made in the CCNA/CCNP exams can anyone say if the CCDA/CCDP 2.0 exams will be radically different to CCDA/CCDP 1.0? Also if you mix CCDP 1.0 with the CCNP 2.0 do you end up recertifying earlier? Anyone in the know here as I'm trying to get a direction and stratergy for CCDA/CCNP and eventually CCDP? Thanks Karl

Re: how to configure VLAN on 2900 switch-how about full duplex an d spanning tree
A VLAN is logically the same as a physical routed LAN. Users on the same VLAN generally belong to the same IP subnet. VLANs are created for the following reasons: 1. Containing the propogation of broadcasts in a switched environment. 2. Security 3. VLANs can be more flexible than traditional routed LANs. For example, if a user needs to move from one VLAN to another (e.g employee changing departments) their PC can move to that VLAN by configuring the switch port to be in the appropriate VLAN. There is no need for re-patching.

Re: Static Routing or Route Maps
There are a couple of issues to clarify here: 1. If the 2 routers are not on the same LAN, HSRP is irrelevant (as has been pointed out below). 2. If on the same LAN HSRP can work well because it IS capable of detecting WAN link failure (you can configure it to "track" the WAN interfaces). You can also use the preempt feature to ensure that the preferable link will always get used if it is available. 3. Are these static routes being redistributed into a dynamic routing protocol? If they are then you configure the redistribution metric to bias one over the other. 4. In any case running a dynamic routing protocol to an ISP is usually not a good idea (security, plus co-ordination with the ISP).

RE: Switch backplace capacity - how much do you need?
Also, just a quick point, you never get 100Mbps (or 200Mbps full duplex) throughput, only about what... 65% max anyway? So you can figure that into your calculation too. Also, you don't think you'll ever run Gigabit Ethernet to the desktop with some new and improved NICs? Might be sooner than you think. We actually are doing that with some servers, in addition to ultrawide SCSI to an EMC. Not sure how you post to the list, so I sent to you also just in case. :-P Jim Croyle Systems Engineer -Original Message- From: John Neiberger [mailto:[EMAIL PROTECTED]] Sent: Monday, July 03, 2000 12:18 PM To: [EMAIL PROTECTED] Subject: Re: Switch backplace capacity - how much do you need? I've wondered about this myself. Consider the Catalyst 4006 as an example. It has a 60 Gbps backplane. Yes, you read that correctly...SIXTY gigabits per second...in a chassis that can hold five modules plus a supervisor module. Do we really *need* that much? My guess is no, we do not need quite that much. however, nowadays I would pick the switch with the higher backplane if I had the bucks to get it. It's nice to know that what's under the hood can handle anything we throw at it. Another example: we are going to be purchasing a 6509 with 256 Gbps backplane. Why? Because we can. No other reason.

Besides, I'm a speed demon and as long as it's someone else's money (my employer's) then I want the biggest, fastest, coolest stuff around. Now, if it were MY money, that's another story. I'd be a little more realistic about my needs. No one is going to be running every port, full duplex, at max capacity.

Re: Static Routing or Route Maps
If you have 2 links, why not utilize them the best you can? Here's what I would do: 1.) Run HSRP on the routers inside interfaces. Configure it to track the serial interfaces on both routers. 2.) Run BGP and learn FULL internet routing table on both routers. Run a cross over cable between the routers and do IBGP on them. This will help protect against an upstream ISP failure or just a plain BGP failure with one of the ISP. HSRP can only track a physical outage. This will also allow, dynamically, the routers to choose which ISP to use for OUTBOUND traffic. If one ISP is down, router 2 will still have the full route table from r1 via iBGP. 3.) Make sure your networks are both be routed to the ISPs. You can telnet to route-server.cerf.net and see if they are. By advertising to both, they will both advertise for you, and the world will take the path with the shortest AS_PATH attribute coming to you. 4.) Now you have redundancy outbound/inbound and a backup strategy that is dynamic. It's a little more complicated than that but it should give you an idea.

NTP Authentication again!
Hi guys, I remember while ago we talked about NTP with authentication, I configured some routers last Friday with "ntp server " and authentication. I did not work in the morning of last Friday, I waited till the afternoon, same thing, I thought I was wrong somewhere, but as it was not big issue for the client, I was not worried about it at all. This morning, I noticed, all the routers are having the right time, but when I use 'sh ntp association', and 'show ntp statu', I found that they are not sychcronized with the ntp master. I will dig this when I have time. Thanks Kent __ Do You Yahoo!? Kick off your party with Yahoo!

Rate-limiting
Hi all I posted a question a while back asking how to limit the maximum speed of an IP address. Well I have kinda got something working that does do that, but it limits everything! access-list 5 permit 10.1.1.2 access-list 5 deny any Ethernet 0 ip address 10.1.1.1 255.255.255.0 ip address 10.1.2.1 255.255.255.0 secondary rate-limit input access-group 5 128000 128000 128000 conform-action transmit exceed-action drop rate-limit output access-group 5 128000 128000 128000 conform-action transmit exceed-action drop I want this configuration to limit the bandwidth of IP address 10.1.1.2 to 128k which it does, but it limits everything else also.

Re: Switch backplace capacity - how much do you need?
Title: Re: Switch backplace capacity - how much do you need? I have noticed that these numbers are actually not necessarily accurate either. The Catalyst 6509 has a backplane quoted as having 256Mb/sec, 128Mb/sec, 32Mb/sec and 16Mb/sec. Which is true? Sort of they all are, from my current information. There are only empty traces right now for the 256G backplane. These new switch fabric/line cards are not yet shipping and the current ones *do not touch* those high speed traces. It will require at least one of the two center slots to be empty for the fabric and some (as yet unknown 0-16) number of ports on the switch fabric cards. So all you have now is the 16G Full Duplex which is still quite a bit, but definitely not 256G (or even 128G Full Duplex ;-) ). The current backplane is quoted as either 32G total or 16G Full duplex. Kind of like the Marketing version of Fast Etherchannel being 200Mb/per link (or 100Mb Full Duplex). There are other issues with it's Jumbo frame support as well, but that is another story... BTW, I there are some Cisco docs that re-badge the Cat5500 backplane as a 7.2G (3 x 1.2G *Full Duplex*)... Is this really the case? I still think Cisco makes some great stuff, but you have to dig more since marketing is replacing truthfulness everywhere. I believe Cisco is not alone in this... I am thankful we have access to a few excellent Cisco folks to help us keep this straight as the big company does not do it well anymore. Take care, Corey McCormick

It doesn't quite work that way. With a hub, any port transmitting at a given instant will be sending to all of the other ports at 10 Mbps. They have to take turns. If two try to transmit at the same time there will be a collision and a random delay, then retry. > >2) As the users complain about the speed, my boss asked me to use the brand > >new 2900 switch (100M speed) to replace the 3com hub.

A switch is capable of making smarter decisions than a hub as far as directing traffic, and when one port is transmitting will direct the output to only the port that needs to listen. With a switch, PC A can be sending to PC B at the same time that PC C is sending to PC D. If you have only one connection between the two switches, then the total traffic between devices connected to the different switches is limited to 100 Mbps. It would be a good idea to confirm that the link between the switches is set to 100 Mbps, full duplex on both ends. The previous response is incorrect, full-duplex can and will work between two switches with a single cable. > >3) But user still complain about the speed, I use the ftp function to check > >the speed and found the speed is only 150kb/sec= 0.15M only.

If all of the devices are on the same network, you shouldn't need to worry about VLANs. Spanning-tree will happen automatically, and just delays the time it takes for a port to go active when a device is first plugged in for about 50 seconds.

Re: Slow Speed in 2900 Switches, Pls Help!!
A hub provides shared bandwidth, so in your first example, the five stations are sharing 10 Mbps. How much of the 10 Mbps they each get depends on the traffic load that they generate, the timing of their packets, etc. You plan to move to a switch. A switch provides dedicated bandwidth to each port on the switch. In your example, you said that you are using 100 Mbps, so each port on the switch provides 100 Mbps. Half-duplex means that a station cannot send and receive at the same time. If an Ethernet station on a twisted pair cable receives on its receive pair while it is sending on its send pair, that is considered a collision. If you are connecting just a single station to the switch port, then you can configure the switch port and the station for full duplex. This allows the switch port and the end station to send at the same time. They no longer consider receiving while sending a collision event. Many people call this 200 Mbps since both stations can theoretically send 100 Mbps at the same time. I suggest you read the Ethernet section in any of the many good CCNA or CCDA books. As the other responder said, you may want to hold off on learning about spanning tree, VLANs, trunking, etc., for now. You should focus on basic Ethernet functionality. Also learn more about the switch commands you can use to measure broadcast traffic, so you can determine if that really is your problem or not. When measuring FTP throughput, keep in mind that the results may be in Bytes per second, so multiply by 8 to get bits per second. Also, FTP throughput is application-layer throughput and includes header overhead (IP, TCP and FTP), delay at the client and server side, acknowledgement time, etc. You should not expect application-layer throughput to equal more than about 30 or 40 percent of raw data-link-layer capacity. As far as troubleshooting slow speed is concerned, we would need lots more data to actually help you, but by using a protocol analyzer you can often determine if it's the network that is slow, the server, or the client. It's usually not the network!
