PRI reseting router

vanagon2tdi · ‎04-14-2004

I have a Cisco 3600 with multiple T1’s and running IOS ver 12.3.4T.

My two PRI’s connected to Sprint are setup with primary-5ess and the Telco has them configured as a group. When one fills up with calls the other will accept calls. If I plug in my second PRI the router resets itself about every 30 minutes. Once I unplug it the router runs fine. Here is my sh ver:

Cisco IOS Software, 3600 Software (C3660-IS-M), Version 12.3(4)T2, RELEASE SOFTWARE (fc1)

TAC Support: http://www.cisco.com/tac

Does anyone have any suggestions why it would be resetting with both plugged in?

Can you also post the output from a "show stack"?

Thanks,

Was there any more to the output?

Yes there was more to the output, but it goes on for a long long time. BTW last night we upgraded the IOS to 12.3-4T4 and that seemed to stabablizwe things.....for now. It has been up for about 10 hours and running ok. Thanks for your help i will post again if this has not solved it.

cdfowlie · ‎04-15-2004

Sounds good. I was going to try and dig out a bug ID for you on that one. In the future, if you have a CCO login, you can capture a "show version" and "show stack" or even a "show tech" in a text file and submit it to the output interpreter linked off the "Technical Support -> Tools and Utilities" page of CCO. This will identify potential bugs and fixes to you. It definitely looks like you had an IOS bug that was resolved in your new load.
