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:
*A:ALA-2009>config>service>vpls>mac-move# show service id 500 mac-move
