  Working with VLANs
Figure 18-25 Edge EFPs Displayed Inside and Outside of Switching Entities
You can delete EFPs and switching entities that have a reconciliation icon by right-clicking them and 
choosing Delete. After all switching entities and EFPs are deleted from a network VLAN, the empty 
network VLAN is automatically deleted from the Vision client after a few minutes.
Switching Entities Containing Termination Points
For certain devices (for example, the Cisco 7600 series, Cisco GSR series, and Cisco ASR 9000 series 
devices), the related switching entities can contain Ethernet flow point elements that serve as termination 
points on different network VLANs. If a single map contains both the switching entities and the network 
VLANs, a link is displayed between them. 
Adding and Removing VLANs from a Map
Adding VLANs to a Map
You can add VLANs to a map if the VLANs were previously discovered by Prime Network and are not 
currently displayed in the map. 
NoteAdding VLANs affects other users if they are working with the same map. 
To add VLANs to a map: 
Step 1In the Vision client, display the map to which you want to add the VLANs.

Step 2Choose File > Add to Map > VLAN. The Add VLAN to map dialog box is displayed as shown in 
Figure 18-26.
Figure 18-26 Add VLAN Dialog Box 
Step 3
In the Add VLAN dialog box, do either of the following: 
Choose a search category, enter a search string, then click Go to narrow the VLAN display to a range 
of VLANs or a specific VLAN. 
The search condition is “contains.” Search strings are case-insensitive. For example, if you choose 
the Name category and enter “net,” the Vision client displays VPNs “net” and “NET” in the names 
whether net appears at the beginning, middle, or at the end of the name: for example, Ethernet.
Choose Show All to display all the VLANs. 
Step 4Select the VLANs that you want to add to the map. 
TipPress Shift or Ctrl to choose multiple adjoining or nonconsecutive VLANs.
Step 5Click OK. 
The VLANs are displayed in the Vision client content pane as shown in Figure 18-27.
Any tickets that apply to the VLANs are displayed in the ticket pane.

After you add a VLAN to a map, you can use the Vision client to view its switching entities and Ethernet 
flow points. For more information, see:

Viewing EFP Properties, page 18-51
You can view additional information about REP and STP in logical inventory, VLAN domain views, and 
VLAN overlays.

Removing VLANs From a Map
You can remove one or more VLANs from the current map. This change does not affect other maps. 
Removing a VLAN from a map does not remove it from the Prime Network database. You can add the 
VLAN to the map at any time.

  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 Vision client 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 1In the Vision client, double-click the device with VLAN mappings configured.
Step 2In the Inventory window, choose Physical Inventory > Chassis >slot>port. 
Step 3Click 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 18-28.

Table 18-32 describes the information that is displayed in the VLAN Mappings table. 
Working with Associated VLANs
Prime Network discovers associations between network VLANs and displays the information in the 
Vision client. Network VLAN associations are represented by VLAN service links, and can be any of 
the tag manipulation types described in Table 18-33.
Table 18-32 VLAN Mappings Table
Field Description
Direction Whether the VLAN mapping is defined in the incoming or outgoing 
direction: In or Out.
VLAN Customer-side VLAN identifier. 
Inner VLAN Used for two-to-one mappings, the customer-side inner VLAN 
identifier. 
Translated VLAN Translated, or mapped, service-provider side VLAN identifier. 
Translated Inner VLAN Translated, or mapped, service-provider side inner VLAN identifier. 
Action Action taken if the VLAN traffic meets the specified mapping: Translate 
or Drop.

Adding an Associated VLAN
To add an associated VLAN to an existing VLAN in a map: 
Step 1In the Vision client, select the required VLAN in the map view.
Step 2Right-click the VLAN and choose Add Associated VLAN. 
The Add Associated VLAN table is displayed as shown in Figure 18-29.

Viewing Associated Network VLAN Service Links and VLAN Mapping Properties
After you add an associated network VLAN, you can:
View the associated network VLAN service links in the Vision client in the thumbnail view. 
View VLAN mapping properties in the Link Properties window.
To view associated network VLAN service links and VLAN mapping properties:
Step 1Select the required network VLAN in the map view. 
Step 2Right-click the VLAN, then choose Show Thumbnail. 
Figure 18-30 shows an example of a network VLAN in a thumbnail.
The VLAN service links are displayed as 4.3.2 between the associated network VLANs. The links 
represent the connections between the Ethernet flow points that are part of each network VLAN.

  Working with VLANs
If VLAN tag manipulation is configured on the link, the VLAN Mapping Properties area in the Link 
Properties window displays the relevant information. For example, in Figure 18-31, the VLAN Mapping 
Properties area shows that a one-to-one VLAN mapping for VLAN tag 1709 to VLAN tag 709 is 
configured on GigabitEthernet1/1/1 on c7-sw8 on the egress direction. 
Figure 18-31 VLAN Mapping Properties in Link Properties Window

Viewing STP Properties for VLAN Service Links, page 18-84
Viewing VLAN Links Between VLAN Elements and Devices
If a Vision client map contains a VLAN and the network element on which the VLAN is configured, 
along with EFPs, switching entities, or network VLANs, you might see what appear to be multiple 
associations between the logical and physical entities. Actually, however, you are seeing other views of 
the original VLAN link. 
For example, assume that you have the following situation, as shown in Figure 18-32 and described in 
the following paragraphs.

Figure 18-32 VLAN Elements and Devices in the Vision Window
The elements are configured as follows:
Port GigabitEthernet1/1/2 on element c7-sw10 is connected to port GigabitEthernet1/1/2 on element 
c7-sw8 by an Ethernet topology link.
Port GigabitEthernet1/1/2 on element c7-sw10 is a trunk port associated with VLAN-1704 which is 
configured on element c7-sw10.
Port GigabitEthernet1/1/2 on element c7-sw8 is a trunk port associated with VLAN-704 which is 
configured on element c7-sw8.
Port GigabitEthernet1/1/2 on element c7-sw8 has a VLAN mapping to tunnel VLAN-1704 
(C-VLAN) in VLAN-704 (SP-VLAN).
In this example, VLAN discovery identified two network VLANs: VLAN-1704 and VLAN-704. Each 
of these network VLANs contains a switching entity and an EFP that represent the connected ports, 
GigabitEthernet1/1/2@c7-sw10 and GigabitEthernet1/1/2@c7-sw8, respectively.
The four links in the map are identified in Figure 18-33 and described in the following table.
