Usage Guidelines
Each VLAN access map can include one match command and one action command.
Examples
This example shows how to create a VLAN access map named vlan-map-01, assign an IPv4 ACL named ip-acl-01 to the map, specify that the switch forwards packets matching the ACL, and enable statistics for traffic matching the map:
switch(config)# vlan access-map vlan-map-01
switch(config-access-map)# match ip address ip-acl-01
switch(config-access-map)# action forward
switch(config-access-map)# statistics

vlan filter
To apply a VLAN access map to one or more VLANs, use the vlan filter command. To unapply a VLAN access map, use the no form of this command.

5.2(1)N1(1) |
This command was introduced. |
Usage Guidelines
You can apply a VLAN access map to one or more VLANs.
You can apply only one VLAN access map to a VLAN.
The no form of this command enables you to unapply a VLAN access map from all or part of the VLAN list that you specified when you applied the access map. To unapply an access map from all VLANs where it is applied, you can omit the VLAN-list argument. To unapply an access map from a subset of the VLANs where it is currently applied, use the VLAN-list argument to specify the VLANs where the access map should be removed.
Examples
This example shows how to apply a VLAN access map named vlan-map-01 to VLANs 20 through 45:
switch(config)# vlan filter vlan-map-01 20-45
