Re: AS5200 router resets unexpectedly.

thompson · ‎05-20-2003

Our Cisco AS5200 has been resetting at irregular intervals with the folowing error. I have replaced the flash memory with some extras I had kicking around. I have also replaced the memory with memory from another router.

Any insight would be appreciated.

Here are the vitals .....

You need to issue command "sh stack" and plug that output at the url below

https://www.cisco.com/cgi-bin/Support/OutputInterpreter/home.pl

Select "show stack".

That stack decoder will decode it and give you possible matching bug.

11.3(9)T id bit old so try to updrade to 12.0 atleast.

The router "completely" failed this morning, so it looks like it was hardware. :-(

Thanks for your input in any case.

From the output given by you , it is clear that the router is trying access an address which is in the invalid range of address. Please see the address from the line

System restarted by bus error at PC 0x220ECB84, address 0x213A7E2.

The address 0x213A7E2 doesnt fall between any of the ranges from the output

Region Manager.( given in your problem statement)

This indicates router is trying to access an outside range of address from the memory. This is a IOS software issue.

Get the "show stacks" command output and use the "Out put interpreter tool" . This is accessible to registered user. If you have CCO login, you can use this
