Enabling MAC Move
The mac-move feature is useful to protect against undetected loops in your VPLS topology as
well as the presence of duplicate MACs in a VPLS service. For example, if two clients in the
VPLS have the same MAC address, the VPLS will experience a high re-learn rate for the MAC
and will shut down the SAP when the threshold is exceeded.
Use the following CLI syntax to configure mac-move parameters.
CLI Syntax: config>service# vpls service-id [customer customer-id] [vpn
vpn-id] [m-vpls]
mac-move
move-frequency frequency
retry-timeout timeout
no shutdown
The following example displays mac-move information.
