MAC Address-Based Traffic Blocking

Configuring MAC Address-Based Traffic Blocking

To block all traffic to or from a MAC address in a specified VLAN, perform this task:



     Router(config)# mac-address-table static mac_address vlan vlan_ID drop

     Blocks all traffic to or from the configured MAC address in the specified VLAN.

     Router(config)# no mac-address-table static mac_address vlan vlan_ID

     Clears MAC address-based blocking.


This example shows how to block all traffic to or from MAC address 0050.3e8d.6400 in VLAN 12:

Router# configure terminal
Router(config)# mac-address-table static 0050.3e8d.6400 vlan 12 drop
