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 relearn rate for the MAC and will shut down the SAP when the threshold is exceeded.
Use the following syntax to configure mac-move parameters.
— 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 is sample mac-move information.
