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 re-learn rate for the MAC and shuts down the SAP or spoke-SDP 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
        — primary-ports
            — spoke-sdp
            — cumulative-factor
        — exit
        — secondary-ports
            — spoke-sdp
            — sap
        — exit
        — move-frequency frequency
        — retry-timeout timeout
        — no shutdown

The following example shows a mac-move configuration:
