Dell Networking S6000 System, Reference Manual

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.
NOTE: If you configure this command on an interface in a routed VLAN, and
after the MAC addresses learned reaches the limit set in the
mac learning-
limit
command, IP protocols are affected. For example, VRRP sets multiple
VRRP Masters and OSPF may not come up.
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.
