3750E stacked Switch is running out of MAC-address space

[manokma01]

on a cisco 3750e stacked switch , we are running out of mac-address space.

eg:  Total Mac Address Space Available: 0

The current template is "desktop default" template i was of the opinion to change the Default SDM template or break out the stack.

Any other suggestions ? any way to check why so many mac-address are present in device?

Desktop default only allows 6000 macs , change it to template vlan you will get 12000 macs allowed

Other than that yes break the stack you will get 6000 back per switch , also check your timers are not too long and switch is storing macs that are not even in use
