Description
Enable MAC pinning on an interface. When you enable MAC pinning on an interface in a bridge domain or VPLS domain, MAC addresses learned over that interface cannot be relearned on any other interface in the same bridge domain or VPLS domain until the MAC address is cleared from the MAC table. If the same MAC address is learned over any other interface in the same bridge domain, it is discarded. This, effectively, controls MAC address moves and prevents creation of loops in Layer 2 bridges.
If the timeout interval for the MAC addresses is not specified
by setting the mac-table-aging-time statement, the MAC
addresses learned over the MAC pinning interface are pinned to the
interface until the default timeout period.
Default
MAC pinning is not enabled.
