Configuring VLAN Maps
Applying a VLAN Map to a VLAN
Beginning in privileged EXEC mode, follow these steps to apply a VLAN map to one or more VLANs:
To remove the VLAN map, use the no vlan filter mapname vlan-list list global configuration command.
This example shows how to apply VLAN map 1 to VLANs 20 through 22:
Switch(config)# vlan filter map 1 vlan-list 20-22
Using VLAN Maps in Your Network
These sections describes how to deny access to a server on another VLAN (see the “Denying Access to
a Server on Another VLAN” section on page 34-35 ).
Denying Access to a Server on Another VLAN
You can restrict access to a server on another VLAN. For example, server 10.1.1.100 in VLAN 10 needs
to have access denied to these hosts (see
Figure 34-4 ):
• Hosts in subnet 10.1.2.0/8 in VLAN 20 should not have access.
• Hosts 10.1.1.4 and 10.1.1.8 in VLAN 10 should not have access.
