3550-12G Crashed

huang.jeff · ‎05-13-2009

I have a 3550-12G Switch. Last Saturday, after issued the "show cdp nei detail", the switch was hung and then crased.

From the "show version", I saw the following message.

System returned to ROM by error - Program Exception (0x0700)!, PC 0x0.

And the IOS Version is 12.1(22)EA1a, is this a bug? I can't find it in bug toolkit.

Don't know if it is or not but code version is pretty old , believe it is up to like 12.2.44SE6 or something like that now . this what the output interpreter says which sort of points to software.

ERROR: A system crash due to the 'Program Exception' error is usually caused bya software issue.

If you do a "dir", can you find the crashinfo file? If so, can you attach the file so we can have a look?
