You can configure ESRP to restart ports in the ESRP master domain when the downstream switch is from a third-party vendor. This action takes down and restarts the port link to clear and refresh the downstream ARP table.
If a switch becomes a slave, ESRP takes down (disconnects) the physical links of member ports that have port restart enabled. The disconnection of these ports causes downstream devices to remove the ports from their FDB tables. This feature allows you to use ESRP in networks that include equipment from other vendors. After 2 seconds, the ports re-establish connection with the ESRP switch.
