Cisco 3600 at 100% CPU! 800ms ping time! *update new question*

I am not the network tech here but I would really appreciate any thought to why this is? The phone is driving me crazy!!!
 
show proc cpu - what is causing the hog?

get a console connection if you can.

did anybody turn on any debugging (rookies like to do this). enter "u all" at command prompt to disable logging

routing protocols not converging? too much traffic (doubtful)

doing any kind of bridging on the router? spanning-tree loop if you are?

if this is really hurting you then call cisco with a network down emergency. if it is REALLY hurting service then get clearance to boot 'em.

 
Are any and all IIS boxes behind the router patched? Do you have an excessive number of Subnets local to the router with a small number of hosts? Do you have a firewall to protect the router from the internet?

Routers are getting hurt right now due to a "CodeRed 3 or Code blue or W32.nimda.a.mm" Worm that seems to be hitting from all angles and as such we will see box performance, routers, and (with smaller links) network issues riseing swiftly. Seems to be hitting Web Servers, rumor of TFTP useage and even telnet probes also.
 
I wish I knew more about this 🙁, the phone calls are driving me nuts! People are asking whether we are having financial problems and wondering if we are going under without telling anyone!

I will keep you updated whenever I find out what is going on... sometimes I wish I had a CCNA
 
hmm... I just talked to a client on our network and he mentioned being hit by nimda.exe, this must be related to code blue...
 
Our system admin is looking at it right now. He has rebooted the router and it comes back. We don't have a dial-in access for it. Usually he terminal servers to a computer here then telnets to the router.
 
It's definitely related to code blue 🙁, I can't wait to get the calls from people inquring about their stats and all the error pages 🙁
 
What kinds of PCMCIA cards can go into this router? We need a RAM card inorder to upgrade the IOS. Do they have to be ordered or can the be purchased localy in a city like Vancouver?
 
did cisco recommend an IOS upgrade?

you shouldn't need a new card. 3600s were release when 12.0 was around. what size flash/RAM/pcmcia do you have now?
 
Do you buy your supplies via a reseller? If so, I'd look to them first. If not, maybe a quick purchase at an internet online store like staples.com or buy.com may be of service.
 
I don't think we have one that's the problem. I couldn't find anything at staples website.

The reason we want the new IOS on there is to ban invalid URLs from being accessed (ie. /default.ida). Our router isn't behind a firewall.
 
I wish I fully understood the problem right now... I am not sure what to tell the customers. I found out that we have a new router coming in though... Cisco 7500.4??? Does that sound right?
 
your company does not deserve a 7500 if there isn't a firewall.

A 3600 shouldn't be pegged at 100% proc unless there is something wrong.

even with DS3 and ATM cards it can keep up
 
My boss just offered to pay for me to get a CCNA and a raise if I don't take co-op this spring 🙂

I agree with the firewall though. I was suprised when I found out we didn't have one.
 


<< your company does not deserve a 7500 if there isn't a firewall. >>



LMAO

Not at you Mucman, I feel your pain. But someone there made some bad decisions.
 


<< We don't have a firewall! >>

That response, ladies and gentlemen, rates a SHOCK BLOCK:
