Hi everyone!


I've got stack of 9 C3750-48-TS. Some PC's have connectivity problem.


For example: I see interface status connected but I don't see PC's MAC-address on this interface.


When I use

show mac-address-table count

command, I've got:

Total Mac Address Space Available: 0


I guess here the problem is. May be it's possible to increase CAM table size somehow?

This stack is a part of L2 domain. If I understood you right.


Sorry my bad English, it isn't my native language.

I found solution by decreasing mac-address table aging time from 300 sec to 60 sec.
