CLI Guide

MAC Learning Limit violation logs and actions are not available on a per-VLAN
basis.
With the keyword no-station-move option, MAC addresses learned through this
feature on the selected interface persist on a per-VLAN basis, even if received on
another interface. Enabling or disabling this option has no effect on already learned
MAC addresses.
After the MAC address learning limit is reached, the MAC addresses do not age out
unless you add the dynamic option. To clear statistics on MAC address learning,
use the
clear counters command with the learning-limit parameter.
When a channel member is added to a port-channel and there is not enough ACL
CAM space, the MAC limit functionality on that port-channel is undefined. When
this occurs, un-configure the existing configuration first and then reapply the limit
with a lower value.
