The router reads the source MAC address of packets passing through the service.

The router uses reverse ARP (RARP) to resolve the MAC addresses for unknown destinations.

The router is programmed with MAC addresses by the network administrator.

How many SAPs can be configured on a port configured with dot1q encapsulation?

None. This encapsulation is not supported.

The number is limited only by the capacity of the router
