RE: Windows 2000 sniffer
EtherPeek 4.1 works on Win2K also. Coming from a Mac background I've always been quite "snobbish" about Etherpeek. However I had a chance to play with SnifferPro4.5 for a few days last week (a friend works at a place with a much larger budget than I get) and have to say that it's decoders are better than EtherPeek. Now if only SnifferPro would show the packets as they capture them (someting that it's predecessor NetXray had, I believe) I would be truly converted. Seeing packets as them come on the wire (rather than having to stop to decode them) has helped me with problems in the past There is also a large price difference also Plus SnifferPro has hardware capture devices for just about every transport possible.

RE: Can someone interpret this please?
As far as I understand... (standard disclaimer) The first number is the total CPU utilization... The second number (after the /) is the total utilization that is being used for interrupts. The difference between these 2 numbers is the amount the router uses for the processes listed below the line. In your case almost 100% of the CPU usage is for interrupts (fast switching is something that causes interrupts) and very little is being used for the various router (proccess switching is done via a proccess) processes. This is possibly good in the fact that all your traffic is being fast switched but bad in the fact that the router is getting overloaded on traffic at it's interfaces.

RE: NAT & HSRP Problem
Currently the IOS does not support NAT & HSRP operating together It's not a bug as they do mention it somewhere on CCO (possibly in the NAT FAQ) There is both the problem with the standby router not knowing the NAT translation table of the active router and the fact that NAT won't use the virtual MAC address but uses the actual physical address I've heard that they are working on a enhancement that should address both issues.

RE: Multicast: Router and Switch locations
In a simple setup like (where you are not actually routing multicast traffic but would like CGMP to control multicast traffic at the switch check out: http://www.cisco.com/warp/customer/473/38.html It can be done as long as you have 1 router interface in the VLAN. The secret is to not enable multicast routing at a global level but enable PIM on the interface. This will then allow CGMP packets to be sent from the router to the switches. The switches will then not pass multicast groups to any port that has not received IGMP packets requesting such groups Another choice would be to use IGMP snooping if your switch supports it... You don't need a router for multicasting if everything is in a single broadcast domain The multicast server will just spit out data, the clients will receive it... The clients will send IGMP requests but since everything is in a single VLAN they are not needed -Original Message- From: Ole Drews Jensen [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 17, 2001 11:38 AM To: '[EMAIL PROTECTED]' Subject: Multicast: Router and Switch locations Currently reading about Multicast, which I have not any experience with yet. If you have a small simple LAN with 1 fileserver, 10 workstations and 1 router to the Internet: INTERNET---[router]---[switch]---[fileserver & 10 workstations] In order for that fileserver to send multicast data to participating workstations without changing the topology, I would have to setup the router with IGMP and CGMP, so the workstation could tell the router that it joined a group, and the router could then inform the switch with CGMP about that workstation. The fileserver would now send multicast data and the switch would know which interface(s) to forward it out to. Since the server and every workstation has their own connection to the switch (and hence has their own individual collision domain), would I be right in assuming that it would not improve the situation to add an additional router to act like a filter between the switch and the server? INTERNET---[router]---[switch]---[10 workstations] | [router2] | [fileserver] Also, will we see multicasting work without a router or an rsm but only with a switch in the future (I know that switches don't understand IGMP)?

CCO Documents Ordering Page??? [7:4756]

RE: Complete Redundancy [7:8409]
More likely than not both circuits share some equipment along the way. It's not uncommon for carriers to use third party networks if they don't own facilities in the area... You *can* ask for proper circuit diversity from one carrier. You will pay more but you'll know (at least as much as you can with any carrier) that the circuits will be diverse. If you just try 2 seperate carriers you can end up with some common points. At least when you are paying for diversity (from a single carrier) you can bitch about problems like you describe. I've seen the same problem in other areas... WE host in a large co-locate facility. Lots of smaller "co-locate" services also host there. If seen several cases where non-local companies host with 2 seperate "co-locate" companies only to have both sets of equipment in the same facilities. -Original Message- From: Bradley J.

Here is the fix, and I am almost ashamed to say, but I want to pass this on so none of you all fall into the same trap as I did. As I said, in one post before, I kept getting the same error messages even after TAC sent me new memory and a new router. The 3rd TAC engineer was the charm, because he asked me if this was a TELCO version of the 3660. That was a real good question cuss I had no idea, as I have never worked on one. Well, that was the problem, it takes a TELCO FEATURE SET IOS. One telltail clue is that their is not a plastic front on the Telco version. I saw this right off the bat, but thought Cisco had just redesigned it. Man what a day. The other way to see if the router is an Enterprise version or Telco is to run the SN numbers. I can think off all the times i do this before I install an IOS. Maybe i should. Good news is I got it fixed and got a new Router out of the deal (thanks you TAC). And as TAC goes, they have pulled my Butt out of the sling more then once, so I have nothing but good to say for them.

Here is the fix, and I am almost ashamed to say, but I want to pass this on so none of you all fall into the same trap as I did. As I said, in one post before, I kept getting the same error messages even after TAC sent me new memory and a new router. The 3rd TAC engineer was the charm, because he asked me if this was a TELCO version of the 3660. That was a real good question cuss I had no idea, as I have never worked on one. Well, that was the problem, it takes a TELCO FEATURE SET IOS. One telltail clue is that their is not a plastic front on the Telco version. I saw this right off the bat, but thought Cisco had just redesigned it. Man what a day. The other way to see if the router is an Enterprise version or Telco is to run the SN numbers. I can think off all the times i do this before I install an IOS. Maybe i should. Good news is I got it fixed and got a new Router out of the deal (thanks you TAC). And as TAC goes, they have pulled my Butt out of the sling more then once, so I have nothing but good to say for them. Yes I have gotten some DORKS before, but I have the option to tell them to get lost and give me a new Engineer. We pay a lot for this service.

RE: Yet another Terminal Server Question [7:13396]
You can always use the 2509/11 as a normal router (with the 2 serial ports) in your lab. The 8/16 async ports can be used as a terminal server without impacting the labs you work on (assuming you have direct telent access to it's ethernet interface) So you don't need to dedicate the TS just for that purpose But assuming you can setup reverse telnet there is no reason that you *need* a 2509/11 in your lab A simple serial switch works fine You may stumble on one of the fancier models that will switch on some key combinations. This would save you haveing to leave the keyboard to switch.I see lots of old surplus async serial stuff around from the "old days"...

RE: Problems with AIM compression on 3660/2600 [7:13742]
Check out bug id# CSCdm69595 There are several others but they don't show up on CCO (Cisco keeps some bugs private) Essentially hw compression mungs up multicast data on 2600/3600 serial interfaces. They say it was fixed in latter releases of 12.07 so you may want to try one of the 12.1 images... A few other multicast issues I've learned the hard way... Early versions of the 2621 router will not pass multicast traffic through the on board ethernet interfaces (Bug ID CSCdm38511 ) Only fix is a router swap. My office looked like a warehouse for a while we were shipping so many 2621s back to Cisco Multicast fast switching (ip mroute-cache) doesn not yet work with hardware compression (Bug ID CSCdt82560) This has not been fixed as of 12.2x. So if you are tring to save CPU by hardware compressing the multicast data you lose CPU by not being able to fast switch. I recall at least one 30 hour marathon with TAC hopping from various TAC centers worldwide. As far as I recall the 2621 hardware issue was already known at Cisco but the problem with hardware compression (both the munging of data and the fast switching issue) were only discovered when a customer (unfortunately me) tried to do it.

RE: Multichannel Port Adapters [7:15159]
I use a lot of them and I'm quite happy... -It makes cabling a lot easier (those honking V.35 connectors always get in the way) -It takes much less space (you have to put the CSU's somewhere) -You get rid of extra wallwart power adapters (the bain of my POP cabling existance) -It makes troubleshooting easier (one less piece of equipment to go wrong) -You can get the CSU info direct from the IOS CLI (saves needing management access to CSU) -One stop shopping for TAC (no third party vendors to blame) -Everything is programable via IOS CLI (no need to try to program external CSU remotely) They are costly though I've never done a direct comparison... I usually try to have a spare port available incase a single port fails (which I have had happen on several NM-2CT1 cards. Then it's a simple config change and a matter of having someone swap a T1 cable. This should cover you till you can get a replacement. Smartnet can give 4 hour on-site repair though I usually find that you can never get access to remote sites in the same timeframe...

RE: cisco lab [7:15484]
Has anyone ever used TCP/COM from TALtech (www.taltech.com)? It turns a PC into a terminal server and is able to handle up to 16 ports. This should allow you to turn a cheap PC into a 2511 like device for the cost of the app ($250) and a multiport serial card ($??)

Old Router Info??? [7:16087]
On occasion I have been able to pick up old routers for free (not any Ciso stuff unfortunately). Currently I have some Bay Networks and Ascom equipment with both token-ring, sync serial and ethernet interfaces. Some of the equipment is unsupported and some is just old. While not relevant to Cisco certification it is nice to get some experience connecting to other vendors equipment (relevant to real word). Unfortunately finding documentation is proving to be quite difficult (also relevant to real world). Hence I'd love to find a site with basic info on old routers (pw recovery, config, OS info). However if no such resource exists I may try setting up a site. Does anyone know of any such site? Is anyone interested in such a site if I set one up? I'm I the only one that considers collecting old routers fun? Should I admit such a sickness to my wife? Currently I'm looking for any information on Ascom Timeplex boxes. Ascom doesn't seem to exist anymore (at least in the router biz) and I'd love to find basic config info for it..

Simple Net Traffic Generator????
I'm looking for a simple application that will stream TCP or UDP traffic at a controlled rate from one IP address to another.Ideally it would have the following features: 1) Allow changing the bandwidth on the fly ( watch how the routers handle traffic changes) 2) Have rates from say 9.6kbs to 1.5 meg or more (simulate feeds from async to T-1 or even ethernet ) 2) Have some canned traffic but also let you pick your own files (see how various files act with compression) 3) Show traffic drops(so you know when a link is having trouble) This would be great for router labs... I've not yet seen such an application anywhere. I'm familar with Cloud and other apps that simulate a network. I have the network, I just want to simulate different types of traffic...

1) Telus. I feel for you Goto www.customcable.com and they can make you up a cable with a RJ48C at one end (what you are calling a RJ45) and a DB15 male at the other. You can get it whatever length you need so you can locate the router away from the Telus demarcation. They use a custom made T-1 cable (made by Beldon) that is better than any other I've seen. They are not very expensive either.

A: 1,331: 1 to change the light bulb and to post to the mail list that the light bulb has been changed 14 to share similar experiences of changing light bulbs and how the light bulb could have been changed differently. 7 to caution about the dangers of changing light bulbs. 27 to point out spelling/grammar errors in posts about changing light bulbs. 53 to flame the spell checkers 156 to write to the list administrator complaining about the light bulb discussion and its inappropriateness to this mail list. 41 to correct spelling in the spelling/grammar flames. 109 to post that this list is not about light bulbs and to please take this email exchange to alt.lite.bulb 203 to demand that cross posting to alt.grammar, alt.spelling and alt.punctuation about changing light bulbs be stopped. 111 to defend the posting to this list saying that we are all use light bulbs and therefore the posts **are** relevant to this mail list. 306 to debate which method of changing light bulbs is superior, where to buy the best light bulbs, what brand of light bulbs work best for this technique, and what brands are faulty. 27 to post URLs where one can see examples of different light bulbs 14 to post that the URLs were posted incorrectly, and to post corrected URLs. 3 to post about links they found from the URLs that are relevant to this list which makes light bulbs relevant to this list. 33 to concatenate all posts to date, then quote them including all headers and footers, and then add "Me Too." 12 to post to the list that they are unsubscribing because they cannot handle the light bulb controversey. 19 to quote the "Me Too's" to say, "Me Three." 4 to suggest that posters request the light bulb FAQ. 1 to propose new alt.change.lite.bulb newsgroup. 47 to say this is just what alt.physic.cold_fusion was meant for, leave it here. 143 votes for alt.lite.bulb.

RE: OT - but relevant [7:19953]
FYI... 60 Hudson seems to be fine... It's more a telcom location than IP As far as I can tell it's still on commercial power... It's behind the security corridor so there is no access...

RE: Serial is reset? [7:20255]
Typically (assuming the interface was working originally and you've made no changes) this would indicate that the circuit is disconnected... Can you see what the equipment at the other end is saying? Again assuming there hasn't been a configuration change it could be anthing from a cable gone bad (somewhat unlikely if you haven't made any physical changes) to a Telco employee accidently pulling a cross connect in a CO (quite likely in my experience).. You'd be best to start up a trouble ticket with the carrier... > -Original Message- > From: Ouellette, Tim [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, September 18, 2001 5:09 AM > To: [EMAIL PROTECTED] > Subject: Serial is reset?

Cisco VPN Solutions [7:20468]
Hi, I'm looking for comments about various Cisco VPN options allowing access from a home workstation.. As far as I know my options are: 1) Cisco PIX accessed by VPN Client 1.1 2) Cisco 3000 (or 5000) Concentrator accessed by VPN client 3.1 3) Cisco IPsec IOS access by VPN Client 1.1 It would seem that option 3 is the most cost effective (assuming you already have the hardware, you just need to purchase the correct IOS).. Anyone with hints/info/caveats? Appreciate any feedback from people actually using the IOS and the VPN client...

RE: DCE to DTE Back to Back Cable Part number [7:20690]

Hopefully no one from management will have read about the screws or. I'm just waiting for the new "memo" To: All Engineering Staff Re: IP Packets It has come to managements attention that we are continually paying for new packets with our Internet feed. This is a substantial cost and must be stopped.

RE: Bridging and Access-lists [7:24791]
If you are bridging you can only use a layer 2 access list... Essentially you'll only be able to block traffic based on MAC addressing... I think the layer2 access lists start at 700... -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Ole Drews Jensen Sent: Wednesday, October 31, 2001 8:08 AM To: [EMAIL PROTECTED] Subject: Bridging and Access-lists [7:24791] I have an ethernet segment that I would like to put some restrictions on, and after having played around with several solutions, I came to one that I believe is the best. Please do not reply with "why don't you use the firewall", or similar suggestions - because I am looking for a way to get this solution to work. I have placed a Cisco 2514 on a segment so I can create access-lists to filter traffic. I want my segment to have the same IP addresses and be on the same network, so I have assigned the 2514 as a bridge where both ethernet interfaces has the same IP address, and are in the same bridge-group. IP routing has been disabled. This all works fine, except that any access-lists I create on any of the two ethernet interfaces does not block anything at all - it's like access-lists are being ignored when the interfaces works in bridging mode. Here's how it looks very simpyfied: internet---router---firewall---2514---switch---users and servers A part of the config: no ip routing ! interface Ethernet0 ip address 10.25.14.1 255.0.0.0 no ip directed-broadcast no ip route-cache no mop enabled bridge-group 1 ! interface Ethernet1 ip address 10.25.14.1 255.0.0.0 ip access-group 100 in no ip directed-broadcast no ip route-cache no mop enabled bridge-group 1 ! bridge 1 protocol dec ! ip classless ! access-list 100 deny ip any any ! The e0 interface is connected to the firewall, the gateway router, and eventually the Internet. The e1 interface is connected to the switch connecting a workstation. >From that workstation I am browsing the web, but even with the "deny ip any any", I can keep browsing without being blocked. Can someone explain this, and perhaps come up with a solution to fix this problem on this router?
