Working with VLANs
When removing VLANs from maps, keep the following in mind:
• Removing a VLAN affects other users who are working with the same map view.
• This option does not change the business configuration or database.
• You cannot remove virtual routers or sites from the map without removing the VLAN.
To remove a VLAN, in the Prime Network Vision navigation pane or map view, right-click the VLAN
and choose Remove from Map.
The VLAN is removed from the navigation pane and map view along with all VLAN elements such as
connected CE devices. Remote VLANs (extranets) are not removed.
Viewing VLAN Mappings
VLAN mapping, or VLAN ID translation, is used to map customer VLANs to service provider VLANs.
VLAN mapping is configured on the ports that are connected to the service provider network. VLAN
mapping acts as a filter on these ports without affecting the internal operation of the switch or the
customer VLANs.
If a customer wants to use a VLAN number in a reserved range, VLAN mapping can be used to overlap
customer VLANs by encapsulating the customer traffic in IEEE 802.1Q tunnels.
To view VLAN mappings:
Step 1 In Prime Network Vision, double-click the device with VLAN mappings configured.
Step 2 In the inventory window, choose Physical Inventory > Chassis > slot > port.
Step 3 Click VLAN Mappings next to the Subinterfaces tab in the lower portion of the content pane.
The VLAN Mappings tab is displayed as shown in Figure 12-27.
