MAC authentication is subject to the following limitations:
If MAC authentication is configured on ports that are part of a LAG, the authenticated MAC address is forwarded in the egress direction out of any port in the LAG.
If MAC authentication is configured on a port and the port is added to or removed from a LAG, all previously authenticated MACs are reauthenticated by the system.
A small amount of traffic loss may occur while MAC reauthentication is in progress.
