MAC Lockout

MAC Lockout involves configuring a MAC address on all ports and VLANs for
a switch so that any traffic to or from the "locked-out" MAC address will be
dropped. This means that all data packets addressed to or from the given
address are stopped by the switch. MAC Lockout is implemented on a per
switch assignment.
You can think of MAC Lockout as a simple blacklist. The MAC address is
locked out on the switch and on all VLANs. No data goes out or in from the
blacklisted MAC address to a switch using MAC Lockout.
The number of MAC lockouts allowed per VLAN depends on the number of
VLANs you have configured, as shown below.

To fully lock out a MAC address from the network it would be necessary to
use the MAC Lockout command on all switches.
To use MAC Lockout you must first know the MAC Address you wish to block.
