Restricts Layer 2 forwarding between 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 VLAN’s 
gateway 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 gateway routers.

Syntax — 

set security l2-restrict vlan vlan-id

[mode {enable | disable}] [permit-mac mac-addr [mac-addr]]

„

 — VLAN name or number.
