• Display a list of all of the interfaces configured with MAC learning limit or station move violation.
CONFIGURATION mode
show mac learning-limit violate-action
NOTE: When the MAC learning limit (MLL) is configured as no-station-move, the MLL will be
processed as static entries internally. For static entries, the MAC address will be installed in all
port-pipes, irrespective of the VLAN membership.
Recovering from Learning Limit and Station Move Violations
After a learning-limit or station-move violation shuts down an interface, you must manually reset it.
To reset the learning limit, use the following commands.
NOTE: Alternatively, you can reset the interface by shutting it down using the shutdown command
and then re-enabling it using the
no shutdown command.

NIC Teaming
NIC teaming is a feature that allows multiple network interface cards in a server to be represented by one
MAC address and one IP address in order to provide transparent redundancy, balancing, and to fully
utilize network adapter resources.
The following illustration shows a topology where two NICs have been teamed together. In this case, if
the primary NIC fails, traffic switches to the secondary NIC because they are represented by the same set
of addresses.
