Router Interfaces keep going down

Hello there,

Thanks.

Re: Router Interfaces keep going down

Hi Sam --

Q. Is this a Frame-Relay Network?

Q. Have you spoken to your service prvider and if so, what have they said?

Thanks -

Re: Router Interfaces keep going down

No, this is a point to point T1/T3 lines.

The service provider tells us that there is no line errors. It shows that in the sh interface serial command that there is no transitional errors.

Thanks.

Re: Router Interfaces keep going down

your router is either crashing or it is losing power , look at a sh ver this will tell you if it is power or a crash , if it is the same time each day chances are the router is plugged in to something that is on a timer .

Re: Router Interfaces keep going down

The uptime on the router is 2 hours, I think you're right as to why the router keeps crashing everyonce in a while. Could it be the power supply on the router or could it be a UPS issue.

Thanks for your help.

Re: Router Interfaces keep going down

A 7200 would be complaining about a bad power supply , My guess is that the power strip is on some kind of timer that resets at the same time each night , the router is resetting at the same time each night .

Re: Router Interfaces keep going down

No, the router resets at different times, sometimes once a day, once every two days or once every weeks. I wonder if there is an existing issue the current verion of the IOS.

IOS (tm) 7200 Software (C7200-JS-M), Version 12.0(7)T, RELEASE SOFTWARE (fc2) .

I want to check the cisco website and find out if there is a known issuses. I'll probably need to upgrade the IOS before taking any further actions.

Thanks.

Re: Router Interfaces keep going down

We have run 12.0(7) T on many routers and this code is not very stable.

If you are hitting a bug it will tell you in a sh ver , it will sh last restart via software forced crash or something like that ,

paste in a sh ver

Re: Router Interfaces keep going down

Here is the output of sh ver.

Re: Router Interfaces keep going down

the line

System returned to ROM by bus error at PC 0x604BFBBC, address 0xC at 1

is telling you that this box crashed .

this is more than likely hardware . Open a Tac case ,
