set security l2-restrict

Restricts Layer 2 forwarding between clients in the same VLAN. When you restrict Layer 2 forwarding in a VLAN, WSS Software allows Layer 2 forwarding only between a client and a set of MAC addresses, generally the VLAN’s default routers. 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.
