Chapter34 Configuring Network Securi ty with ACLs Configuring VLAN Maps
This example shows how to create a VLAN map to pe rm it a packet. ACL ip2 permits UDP packets and
any packets that match the ip2 ACL are forwarded. In this map, an y I P pa cke ts t hat di d not matc h an y of
the previous ACLs (that is, packets that are not TCP packets or UDP packets) would get droppe d.
Switch(config)# ip access-list extended ip2
Switch(config-ext-nacl)# permit udp any any
Switch(config-ext-nacl)# exit
Switch(config)# vlan access-map map_1 20
Switch(config-access-map)# match ip address ip2
Switch(config-access-map)# action forward
Example 2
In this example, the VLAN map has a default action of drop for IP packets and a default action of forward
for MAC packets. Used with standard ACL 101 and extended named access lists igmp-match and
tcp-match, the map will have the following results:
Forward all UDP packets
Drop all IGMP packets
Forward all TCP packets
Drop all other IP packets
Forward all non-IP packets
Switch(config)# access-list 101 permit udp any any
Switch(config)# ip access-list extended igmp-match
Switch(config-ext-nacl)# permit igmp any any
Switch(config)# ip access-list extended tcp-match
Switch(config-ext-nacl)# permit tcp any any
Switch(config-ext-nacl)# exit
Switch(config)# vlan access-map drop-ip-default 10
Switch(config-access-map)# match ip address 101
Switch(config-access-map)# action forward
Switch(config-access-map)# exit
Switch(config)# vlan access-map drop-ip-default 20
Switch(config-access-map)# match ip address igmp-match
Switch(config-access-map)# action drop
Switch(config-access-map)# exit
Switch(config)# vlan access-map drop-ip-default 30
Switch(config-access-map)# match ip address tcp-match
Switch(config-access-map)# action forward
Example 3
In this example, the VLAN map has a default action of drop fo r MAC packets an d a default act ion o f
forward for IP packets. Used with MAC extended access lists good-hosts and good-protocols, the map
will have the following results:
Forward MAC packets from hosts 0000.0c00.0111 and 0000.0c00.0211
Forward MAC packets with decnet-iv or vines-ip protocols
Drop all other non-IP packets
Forward all IP packets
Switch(config)# mac access-list extended good-hosts
Switch(config-ext-macl)# permit host 000.0c00.0111 any
Switch(config-ext-macl)# permit host 000.0c00.0211 any
Switch(config-ext-nacl)# exit
Switch(config)# mac access-list extended good-protocols
Switch(config-ext-macl)# permit any any decnet-ip
