Setup Guide

• 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]
Enabling port security
You can enable or disable port security feature globally on the Dell EMC Networking OS.
You can congure all the MAC address learning limit congurations, only if the port security is enabled on the Dell EMC Networking OS. If
the port security feature is disabled, all the interface level congurations are reset and all dynamically learnt MAC addresses on the
interfaces congured with MAC address learning limit are cleared.
To enable the port security feature globally in the system, use the following command.
