Hello Jack,

have you tried to reload the switch?


CAM table is a core function of lan switch so you need to understand if device is usable or not.


Hope to help

Hello Jack,

this is likely a software bug because it speaks of handlers.


do a search in the bug toolkit or post the version of your IOS image.


I would use TCAM as search keyword but I see I get no results


Hope to help

Giuseppe

Hi Giuseppe,


yes, but the bugs have been fixed by the newer version. my switch version is 12.2(35)SE5. shouldn't be impacted .
