Enabling Mac Move - Alcatel-Lucent 7210 SAS M Service Manual

Configuring a VPLS Service with CLI

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]
The following example displays mac-move information.
