Nous allons voir comment mettre en place le filtrage mac en ligne de commandes sur les switchs Cisco Catalyst.
Voyons comment autoriser la famille d'addresses 00:11 et l'hôte 24:B6:FD:14:08:53. Les autres adresses seront bloquées.Configuration
Création d'ACL
Switch(config)# mac access-list extended MF01
Switch(config-mac-al)# permit 24:B6:FD:14:08:53 00:00:00:00:00:00 any
Switch(config-mac-al)# permit 48:bd:0e:02:ea:41 00:00:00:00:00:00 any
Switch(config-mac-al)# permit 00:11:00:00:00:00 00:00:FF:FF:FF:FF any
Switch(config-mac-al)# deny any any
Associate MF01 acl to interfaces
Switch(config)# interface range ge1/0/4-18
Switch(config-if-range)# mac access-group MF01 in
Switch(config-if-range)# no mac access-group MF01 in
Commandes Utiles
Switch# show mac address-table
Switch# show mac address-table | include Gi1/0/1
Switch# show access-lists MF01
