Viewing CDP Properties
Cisco Discovery Protocol (CDP) is primarily used to obtain protocol addresses of neighboring devices and discover the platform of those devices.
Note If you have multiple instances of the same hostname connected to each other, the topology might not function correctly. To avoid this problem, configure each device with a unique hostname using the command: hostname unique-name.
To view CDP properties:
Step 1 In Cisco ANA NetworkVision, double-click the device whose CDP properties you want to view.
Step 2 In the inventory window, click Cisco Discovery Protocol.
The CDP properties are displayed in logical inventory as shown in Figure 12-1.

Viewing Connectivity Fault Management Properties
Ethernet Connectivity Fault Management (CFM) is an end-to-end per-service-instance Ethernet layer operations, administration, and maintenance (OAM) protocol. CFM includes proactive connectivity monitoring, fault verification, and fault isolation for large Ethernet metropolitan-area networks (MANs) and WANs. End to end can be PE to PE or CE to CE. A service can be identified as a service provider VLAN (S-VLAN) or an Ethernet virtual connection (EVC) service.
End-to-end technology distinguishes CFM from other Metro Ethernet OAM protocols. For example, MPLS, ATM, and SONET OAM help in debugging Ethernet wires but are not always end-to-end. IEEE 802.3ah OAM is a single-hop and per-physical-wire protocol, but it is not end-to-end or service aware.
Note Cisco ANA does not display information for CFM maintenance end points or maintenance intermediate points for Cisco Viking devices if errors exist in their configurations. An error in the configuration is indicated by an exclamation point (!) in the CLI output.
For example, if you enter the command show ethernet cfm local maintenance-points, a configuration error is indicated as follows:
cfm_d100/2 cfm_s100 Te0/2/0/3.100 Up MEP 2100 eb:7a:53!
To view CFM properties:

Viewing and Renaming Ethernet Flow Domains
An Ethernet flow domain represents an Ethernet access domain. The Ethernet flow domain holds all network elements between the CE (inclusive, if managed by the SP), up to the SP core (exclusive). This includes CE, access, aggregation, and distribution network elements. An Ethernet flow domain can have no N-PEs (flat VLAN) or one or more N-PEs (N-PE redundancy configuration). The Ethernet flow domain is defined using physical connectivity at the port level, and not at the NE level. STP is used to mark the root bridge, root or blocked ports, and blocked VLAN links.
A network VLAN represents the virtual LAN. The network VLAN holds its contained switching entities and can be associated to a customer. The network VLAN also holds the Ethernet flow points that are part of the network VLAN but that are not part of any switching entity; for example, a port that tags ingress flows after which the flow moves to a different VLAN.
A switching entity business element represents the device bridge for the VLAN. The switching entity is part of a VLAN, and holds the network elements representing the bridge, STP bridge information, and the Ethernet flow points at the edges of this bridge.
The Ethernet flow point business element represents a specific Ethernet flow point in a VLAN. The Ethernet flow point holds the network elements representing the STP information on the flow point and the relevant Ethernet interface type.
To view Ethernet flow domains:
Step 1 In Cisco ANA NetworkVision, choose Network Inventory > Ethernet Flow Domains.
The Ethernet Flow Domain List window is displayed with the name and a brief description for each Ethernet flow domain as shown in Figure 12-7.

Viewing Ethernet Link Aggregation Groups
Ethernet link aggregation groups provide the ability to treat multiple switch ports as one switch port. The port groups act as a single logical port for high-bandwidth connections between two network elements. A single link aggregation group balances the traffic load across the links in the channel. If a physical link within the static link aggregation group fails, traffic previously carried over the failed link is moved to the remaining links. Most protocols operate over single ports or aggregated switch ports and do not recognize the physical ports within the port group.
To view Ethernet aggregation groups:
Step 1 In Cisco ANA NetworkVision, double-click the device with the link aggregation group you want to view.
Step 2 In the inventory window, choose Logical Inventory > Ethernet Link Aggregation.
The link aggregation properties are displayed as shown in Figure 12-9.

Viewing Virtual Switching Instance Properties
VPLS is Layer 2 VPN type that provides Ethernet-based multipoint-to-multipoint communication over MPLS networks. VPLS allows geographically dispersed sites to share an Ethernet broadcast domain by connecting sites through pseudowires. The network emulates a LAN switch or bridge by connecting customer LAN segments to create a single bridged Ethernet LAN.
VPLS uses the provider core to join multiple attachment circuits together to simulate a virtual bridge connecting multiple attachment circuits. To the customer, VPLS topology is transparent. All CE devices appear to connect to a virtual bridge emulated by the provider core. The logical bridge performs MAC address learning just like a physical bridge.
Virtual switching instances (VSIs), also known as virtual forwarding instances, are the main PE router components used to create the logical bridge. VSIs used to create a provider logical bridge are connected with MPLS pseudowires.
To view VSI properties:
Step 1 In Cisco ANA NetworkVision, double-click the device containing the VSIs you want to view.
Step 2 In the inventory window, choose Logical Inventory > VSIs > vsi.
VSI properties are displayed in logical inventory as shown in Figure 12-14.

Working with VLANs and VLAN Overlays
The following topics provide procedures for working with VLANs and VLAN overlays:
•VLAN and EFD Discovery
•Adding a VLAN to a Map
•Removing a VLAN from a Map
•Viewing VLAN Mappings
•Adding a VLAN Overlay to a Map View
•Displaying or Hiding VLAN Overlays
•Removing a VLAN Overlay
•Viewing VLAN Trunk Group Properties
•Viewing VLAN Bridge Properties
VLAN and EFD Discovery
When you start the Cisco ANA gateway the first time, Cisco ANA waits a period of time (approximately one hour) before discovering new VLANs and EFDs. This delay allows the system to stabilize, and provides the time needed to model devices and discover links.
Similarly, when you restart the gateway, Cisco ANA uses this stabilization period to add existing information on VLANs and EFDs to maps and logical inventory. EFDs that were previously stored in the database can be viewed in inventory, and VLANs can be viewed in maps.
During this delay, Cisco ANA does not add VNEs or apply updates to existing VLANs or EFDs.
After the initial delay has passed, Cisco ANA discovers new VLANs and EFDs, applies updates to existing VLANs and EFDs, and updates the database accordingly.
Adding a VLAN to a Map
You can add VLANs to a map if the VLANs were previously discovered by Cisco ANA and are not currently displayed in the map. For more information about VLANs, see the Cisco Active Network Abstraction 3.7 Theory of Operations Guide.
Note Adding VLANs affects other users if they are working with the same map.
To add a VLAN to a map:
Step 1 Display the map to which you want to add the VLAN in Cisco ANA NetworkVision.
Step 2 Choose File > Add to Map > VLAN.
Step 3 In the Add VLAN dialog box, do one 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," Cisco ANA displays VLANs that have "net" in their names, whether net appears at the beginning of the name, the middle, or at the end, such as Ethernet.
•Choose Show All to display all the VLANs.
Step 4 Select the VLAN that you want to add to the map.
Tip Press Shift or Ctrl to choose multiple adjoining or nonconsecutive VLANs.
Step 5 Click OK.
The VLAN is loaded in the map view displayed in the Cisco ANA NetworkVision content pane. It is displayed in the navigation pane and the selected map view or subnetwork in the Cisco ANA NetworkVision window content pane. In addition, any tickets that apply to the VLAN are displayed in the ticket pane.
Removing a VLAN 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 Cisco ANA database. You can add the VLAN to the map at any time.
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, sites, LCAs, or LCPs from the map without removing the VLAN.
To remove a VLAN, in the Cisco ANA NetworkVision 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 Cisco ANA NetworkVision, 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 12-15.
Figure 12-15 VLAN Mappings Tab in Physical Inventory
Table 12-17 describes the information that is displayed in the VLAN Mappings table.

|
Adding a VLAN Overlay to a Map View
You can create an overlay of a specific VLAN on top of the physical network elements displayed in a map view. The overlay highlights the network elements and links that the selected VLAN and its associated VLANs traverse. Network elements and links that are not part of the VLAN are dimmed in the map view. The VLAN overlay is a snapshot of the network to help you visualize the network elements and links connected to a VLAN. The overlay displays STP and REP link and port information.
The VLAN service overlay allows you to isolate the parts of a network that are being used by a particular service. This information can then be used for troubleshooting. For example, the overlay can highlight configuration or design problems when bottlenecks occur and all the site interconnections use the same link. For more information about VLAN overlays, see the Cisco Active Network Abstraction 3.7 Theory of Operations Guide.
To add a VLAN overlay to a map view:
Step 1 Display the network map for which you want to create an overlay in Cisco ANA NetworkVision.
Step 2 In the toolbar, choose Choose Overlay Type > VLAN.
Step 3 In the Select VLAN Overlay dialog box, do one of the following:
•Choose a search category, enter a search string, then click Go to narrow the selection to a set of overlays or a specific overlay.
The search condition is "contains." Search strings are case insensitive. For example, if you choose the Name category and enter "net," Cisco ANA displays overlays that have "net" in their names, whether net appears at the beginning of the name, the middle, or at the end, such as Ethernet.
•Choose Show All to view all overlays.
Step 4 Select an overlay, then click OK.
The network elements and physical links used by the selected VLAN overlay are highlighted in the network map. All other network elements and links are dimmed. The VLAN name is displayed in the title of the window. See Figure 12-16.
Figure 12-16 VLAN Overlay Example
Note The overlay is a snapshot taken at a specific point in time. To update the overlay, click Refresh the Last Selected Overlay in the toolbar.
Displaying or Hiding VLAN Overlays
After you create a VLAN overlay, you can hide it by clicking Hide Overlay in the toolbar. All previously dimmed network elements and links are displayed. To display the overlay, click Show Overlay.
Note The overlay icon toggles between Show Overlay and Hide Overlay. When selected, the VLAN overlay is displayed and the Hide Overlay tool is active. When deselected, the VLAN overlay is hidden and the Show Overlay tool is active.
Removing a VLAN Overlay
To remove a VLAN overlay from a map, choose Choose Overlay Type > None in the toolbar. The overlay is removed from the map, and the Show Overlay/Hide Overlay icon is dimmed.
Viewing VLAN Trunk Group Properties
VTP is a Layer 2 multicast messaging protocol that manages the addition, deletion, and renaming of VLANs on a switched network-wide basis.
Cisco ANA displays VTP information in the Cisco ANA NetworkVision logical inventory. VTP information is only shown for Cisco devices that support VTP, and support is provided only for VTP Version 1 and 2. Support for Version 3 is limited to the additional attributes that are supported by the version, such as primary and secondary server. No support is provided for the display of VTP information at the port (trunk) level.
Cisco ANA shows all VTP modes: Server, Client, Transparent, and Off. For each mode, Cisco ANA displays the relevant mode information such as VTP domain, VTP mode, VTP version, VLAN trunks, and the trunk encapsulation. Cisco ANA also displays VTP domain information in a view that includes a list of all switches that are related to these domains, their roles (server, client, and so on), and their VTP properties.
For additional information about VTP, see the Cisco Active Network Abstraction 3.7 Theory of Operations Guide.
To view VTP properties:
Step 1 In Cisco ANA NetworkVision, choose Network Inventory > VTP Domains.
Step 2 Double-click the VTP domain you want to view.
The VTP Domain Properties window is displayed as shown in Figure 12-17.
