Static MAC filtering allows you to associate a MAC address with a VLAN and set of source ports and destination ports. (The availability of source and destination port filters is subject to platform restrictions). Any packet with a static MAC address in a specific VLAN is admitted only if the ingress port is included in the set of source ports; otherwise the packet is dropped. If admitted, the packet is forwarded to all the ports in the destination list.
Use the MAC Filter Configuration page to associate a MAC address with a VLAN and one or more source and/or destination ports. To access the MAC Filter Configuration page, click Switching > Filters > Configuration in the navigation menu.
