[Murphy, William]

If you haven't done it already I would suggest setting logging level for L2FM to 5 and watch the log for errors...

WE are running 6.1.2 on 7k 18 slot  with sup2.


FDB appears to have stopped learning addresses, but some are in table and we are not even close to limit.



Cleared mac address table but no change.

Switched to standby sup but no change.



Has anyone seen this issue ?


I currently have case open and working with TAC but might as well check with group.



Thanks for any help.
