Setting Station Move Violation Actions
no-station-move is the default behavior. You can congure the system to take an action if a station move occurs using one the
following options with the mac learning-limit command.
To display a list of interfaces congured with MAC learning limit or station move violation actions, use the following commands.
• Generate a system log message indicating a station move.
INTERFACE mode
station-move-violation log
• Shut down the rst port to learn the MAC address.
INTERFACE mode
station-move-violation shutdown-original
• Shut down the second port to learn the MAC address.
INTERFACE mode
station-move-violation shutdown-offending
• Shut down both the rst and second port to learn the MAC address.
INTERFACE mode
station-move-violation shutdown-both
• Display a list of all of the interfaces congured with MAC learning limit or station move violation.
CONFIGURATION mode
show mac learning-limit violate-action
NOTE
: When the MAC learning limit (MLL) is congured 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.
• Reset interfaces in the ERR_Disabled state caused by a learning limit violation or station move violation.
EXEC Privilege mode
mac learning-limit reset
• Reset interfaces in the ERR_Disabled state caused by a learning limit violation.
EXEC Privilege mode
mac learning-limit reset learn-limit-violation [interface | all]
• Reset interfaces in the ERR_Disabled state caused by a station move violation.
EXEC Privilege mode
mac learning-limit reset station-move-violation [interface | all]
