Usage Guidelines

To avoid accidentally dropping too many packets and disabling connectivity in the middle of the

configuration process, we recommend that you completely define the VLAN access map before applying

it to a VLAN. If you apply a nonexistent VLAN map to a VLAN, a warning message appears.

For more information about VLAN map entries, see the software configuration guide for this release.

This example applies VLAN map entry map1 to VLANs 20 and 30:

Switch(config)# vlan filter map1 vlan-list 20, 30

This example shows how to delete VLAN map entry mac1 from VLAN 20:

Switch(config)# no vlan filter map1 vlan-list 20

You can verify your settings by entering the show vlan filter privileged EXEC command.

vlan filter mapname vlan-list list

no vlan filter mapname vlan-list list

Name of the VLAN map entry.

The list of one or more VLANs in the form tt, uu-vv, xx, yy-zz, where spaces
