The status-code-change flush-mac disable command configures a VPLS PW not to clear local MAC addresses when it receives the remote status code of 20.
The undo status-code-change flush-mac disable command cancels the configuration of a VPLS PW not to clear local MAC addresses when it receives the remote status code of 20.
By default, a VPLS PW clears local MAC addresses when it receives the remote status code of 20.
Usage Scenario
When VPWS PWs in redundancy mode are connected to a VPLS, if the primary PW becomes the secondary PW, this PW sends the status code of 20 to the VPLS network. By default, a VPLS PW clears local MAC addresses when it receives the remote status code of 20. When a large number of services are running on the VPLS network, clearing local MAC address entries takes a long time, which deteriorates performance. To prevent this, run the status-code-change flush-mac disable command. This configuration prevents the VPLS PW from clearing local MAC address entries when it receives the remote status code of 20.
