Left Widget Options on Topology Page

The left widget menu allows you to filter the data displayed on the topology map. The left widget displays Metrics when you first log in to the web user interface. Hover over the More Options (horizontal ellipsis) to view the other left widget options.

Table 1 describes the left widget options.

Description

Metrics

Displays the percentage and count of the network’s active paths, active links, and active PCCs that are in an UP state.

The display is updated every one to two minutes, depending on the frequency of incoming events. The busier the network, the more frequent is the update. The last updated timestamp is displayed at the bottom of the widget.

The number of paths detoured (using a bypass LSP) and LSPs that are being provisioned are also displayed. These numbers could differ from what is reported in the network information table.

  • Active Paths: Displays the number and percentage of active paths in the topology.

    By design, the Active Paths reported is not the same as what is reported in the Tunnel tab of the network information table because the Tunnel tab includes secondary paths and the Active Paths display does not. If you have a secondary path for any LSPs, the Active Paths displayed and the information in the Tunnel tab in the network information table do not match.

  • Active Links: Displays the number and percentage of active links in the topology.

    Active link numbers always match the Link tab in the network information table if the internal model is in sync with the live network. A mismatch indicates that the internal model has become out of sync with the live network. On a regular basis, when the internal model is updated, it is with changes to the live network topology, not with a rebuilding of the entire topology. So over time, the model and the live network can become out of sync. To correct this problem, reload the internal model with the entire live network information using Reset/Sync Network Model (Configuration >Network > PathFinder). For more information, see Pathfinder Settings.

  • Active PCC: Displays the number and percentage of active PCC in the topology.

    By design, the Active Path Computation Client (PCC) reported is not the same as what is reported in the Node tab of the network information table because the Node tab includes pseudo nodes and the Active PCC display does not. The Active PCC display only includes nodes that are routers; it does not include pseudo nodes such as Ethernet nodes or AS nodes. If you have pseudo nodes in the network, the Active PCC display and the Node tab in the network information table do not match.

Performance

Display current (live network) or historical (analytic traffic collection) data on the topology map.

  • For Current options, you can select any one of the options that you want display on the topology map.

    Note:

    The colors are displayed based on the legend settings configured (on the bottom-right corner of the page).

  • For the Historical options, a slider is displayed in the upper left corner of the topology page. You can slide this to view the historical topology data based on the time range configured in the Settings.
