Restricting Layer 2
Traffic Among Clients
in a VLAN
By default, clients within a VLAN are able to communicate with one
another directly at Layer 2. You can enhance network security by
restricting Layer 2 forwarding among clients in the same VLAN. When
you restrict Layer 2 forwarding in a VLAN, MSS allows Layer 2 forwarding
only between a client and a set of MAC addresses, generally the default
routers (gateways) of a VLAN. Clients within the VLAN are not permitted
to communicate among themselves directly. To communicate with
another client, the client must use one of the specified default routers.
You can specify up to four default router MAC addresses. The addresses
must be unicast (not multicast or broadcast).
For networks with IP-only clients, you can restrict client-to-client
forwarding using ACLs. Use the Restrict L3 Traffic option. (See
“Restricting Layer 3 Traffic Among Clients in a VLAN”.)
