clear security l2-restrict

Removes one or more MAC addresses from the list of destination MAC addresses to which clients in a VLAN are allowed to send traffic at Layer 2.

Syntax clear security l2-restrict vlan vlan-id[permit-mac mac-addr[mac-addr] all]

vlan-idVLAN name or number.

permit-macmac-addrList of MAC addresses. WSS Software no longer allows clients in the

[mac-addr]	VLAN to send traffic to the MAC addresses at Layer 2.
all	Removes all MAC addresses from the list.

Defaults If you do not specify a list of MAC addresses or all, all addresses are removed. Access Enabled.

History Introduced in WSS Software Version 4.1.

Usage If you clear all MAC addresses, Layer 2 forwarding is no longer restricted in the VLAN. Clients within the VLAN will be able to communicate directly.

There can be a slight delay before functions such as pinging between clients become available again after Layer 2 restrictions are lifted. Even though packets are passed immediately once Layer 2 restrictions are gone, it can take 10 seconds or more for upper-layer protocols to update their ARP caches and regain their functionality.

To clear the statistics counters without removing any MAC addresses, use the clear security l2-restrict counters command instead.

Examples The following command removes MAC address aa:bb:cc:dd:ee:ff from the list of addresses to which clients in VLAN abc_air are allowed to send traffic at Layer 2:

WSS# clear security l2-restrict vlan abc_air permit-mac aa:bb:cc:dd:ee:ff success: change accepted.
