Network Information Table Overview

The Network Information Table at the bottom of the Topology page displays detailed network information based on one of the following tabs selected:

  • Node—View node information and add, edit, or delete nodes in the network.

  • Link—View link information and add, edit, or delete links in the network.

  • Tunnel—View tunnel information and provision, edit, or delete tunnels in the network.

  • Interface—View information about various interfaces (such as IPv4, MAC, and VRF) in the network.

  • Anycast Group—View information about different anycast groups in the network. You can view the anycast group Prefix Address, State (valid or not), SR (segment routing) information such as flags and index, and the Members of the anycast group.

    Segment Routing is a forwarding architecture which instructs a router on what to do with certain packets. Multiple types of SIDs supported such as node SIDs, prefix SIDs, Adjacency SIDs, Binding SIDs along with Anycast SIDs.

    Anycast SIDs are a type of prefix SID that represents a group. It is present in multiple devices, and the network can reach any of the members on the group, based on IGP shortest path or potentially any other constraint defined. Anycast SID have multiple use cases, for example, they can be used as transit SIDs (loose hops) on a SR-TE policy, or used as destination (representing a service, or representing border gateways on a multi-domain network).

    For LSPs using anycast group as intermediate hop, the intermediate hop will be a set of nodes. Within an anycast group, all the routers advertise the same prefix with the same SID value, which facilitates load balancing.

  • Container LSP—View container LSP information and add, edit, or delete container LSPs and their sub-LSPs.

  • Maintenance—View information about existing maintenance events and add, edit, simulate, or delete these events.

  • P2MP Group—View information about P2MP group and their sub-LSPs, and add, edit, or delete them.

  • SRLG/Facility—View information about shared risk link group (SRLG) or Facilities and add, edit, or delete them.

  • Topology Group—View information about topology groups in the network. You can edit or delete a topology group.

The Node, Link, and Tunnel tabs are displayed by default. To view other tabs, you can hover over the More Tabs list (next to the Tunnel tab) and select required tab.

Note:

You can show or hide the network information table by clicking the collapsible arrow icon.

Tasks You Can Perform

You can perform the following tasks:

  • Filter Entries—Filter the table entries by adding new filtering criteria.

    Hover over the Filter (funnel) icon and select Add Filter. On the Add Criteria page, select the filtering criteria from the Field and Condition list, and enter the text to be compared in the Value field. Click Add.

    The filtered table entries are listed and the filter criteria name is displayed above the table column names.

    You can click the cross (X) icon (next to the filter name) to remove the filtering criteria.

    Note:

    • You can add multiple filtering criteria. Once you add the multiple filtering criteria, you can select the And condition to display the entries matching all the filtering criteria or select the Or condition to display the entries matching any one of the filtering criteria.

    • Quick filter: Save the filtering criteria as quick filters. Once you have added all the filtering criteria, you can save a particular criteria or multiple criteria for future use by clicking Save.

      On the Save Filter window, enter a name for the filter, optionally toggle the Set as Default button if you want to use this filtering criteria by default, and click OK.

      The saved filters are displayed under Quick Filters when you hover over the Filter (funnel) icon. You can then apply these saved filters to the table entries.

  • Show/Hide Columns—Choose to show or hide a specific column in the table.

    Hover over the More Options (vertical ellipsis) > Show/Hide Columns and select the Column-Name check box of the columns you want to display in the table.

  • Reset Preference—Reset the displayed columns to the default set of columns for each tab in the table.

    Hover over the More Options (vertical ellipsis) and select Reset Preference.

  • Sort Entries—Click the column name to highlight the up and down arrows next to the column name. Sort the table entries in ascending or descending order of that column by clicking the up or down arrow respectively.

Note:

The network information table is not refreshed automatically. If there is a network event, a small yellow indicator next to Refresh icon at the bottom-left of the table is displayed. You must refresh the table explicitly.
