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 12-restrict vlan vlan-id
[permit-mac mac-addr [mac-addr]|all]
vlan-id — VLAN name or number.
permit-mac — List of MAC addresses. MSS no longer allows clients
mac-addr in the VLAN to send traffic to the MAC addresses at
[ mac-addr ] 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 MSS 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.
To clear the statistics counters without removing any MAC addresses, use
the clear security l2-restrict counters command instead.
