Hi Mala,,

In a network with two switch twins 4507, with redundant sup 6E and Version 12.2(52)SG. All days appear 3 log messages that, regarding a messages guides of ios cisco, don't represent any problem, and the recommended action this is an informational message only. No action is required. the level of logging is 5 (notification).. but I have doub it is a real problem...

Hello Mala,

L3HWFORWARDING-4-FLTCAMPARITYERROR: STANDBY: this message means a parity errror in TCAM table in standby supervisor.

if the events are regular it makes me think of a SW bug related to SSO:

the TCAM table of standby supervisor should be in sync with that of active supervisor so that in case of switchover it is ready to take the active role.

if there is no regular pattern in events I would consider if there is any HW in standby supervisor.

Hope to help

Giuseppe
