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 experiences a high relearn rate for the MAC and shuts 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

Example: MAC move information

*A:ALA-1# show service id 6 all
....
