Viewing Link Details of a CSD-Topology for Determining the Operational Status

 

It is necessary to determine the operational status of links configured among devices in a topology to examine and troubleshoot data traffic loss and packet-forwarding problems. You can view the details of all the links configured for devices in the Topology View that are managed by the CSD-Topology. For explicit routing, from the Map view, click the links or nodes to define an alternate route between the source (Node A) and destination (Node Z) nodes to provide a path that is diverse from the path specified in the primary tunnel. When you schedule a maintenance event on nodes or links, the CSD-Topology routes delegated label-switched paths (LSPs) around those nodes and links that are scheduled for maintenance. After the completion of the maintenance event, delegated LSPs are reverted to optimal paths.

To view details of links in the Topology View:

  1. From the Junos Space user interface, click the Build icon on the Connectivity Services Director banner.

    The workspaces that are applicable to Build mode are displayed on the Tasks pane.

  2. From the View selector, select Topology View.

    The topology map of the sites or zones and the devices configured in each zone using the CSD-Topology is displayed on the upper portion of the page. A table with details of devices, services, links, and LSPs is displayed on the lower portion of the page.

  3. Select the Links tab on the lower portion of the page.

    For columns in the table that contain an empty text field displayed at the top of the table on each tab, you can enter the search criterion that you want to use for that particular column or parameter to sort and classify the display of values in the table. For parameters that you can enable or disable, you can select or clear the check boxes respectively. The page is refreshed to display the devices that match the specified criterion. The search criteria that you have entered are displayed above the first row of the table. You can click Clear All displayed beside each of the search terms to remove the previously defined search terms.

    • Link Name—Name of the configured link

    • End A RouterId—Router ID of the starting node of the link. The router ID is used to uniquely identify a router and is the IP address of the loopback interface.

    • End B RouterId—Router ID of the ending node of the link

    • Endpoint A Hostname—Hostname of the router at the starting node of the link. Click in the first cell in the Endpoint A IP column to enter the IP address of the LSP head end that you want to use as the filter for viewing the links.

    • End B Hostname—Hostname of the router at the ending node of the link. Click in the first cell in the Endpoint A IP column to enter the IP address of the LSP tail end that you want to use as the filter for viewing the links.

    • End A Interface Name—Name of the interface on the router at the starting point of the link

    • End B Interface Name—Name of the interface on the router at the ending point of the link

    • End A Interface Address—IP address of the interface on the router at the starting point of the link

    • End B Interface Address—IP address of the interface on the router at the ending point of the link

    • Link Type—Whether the link is an IP link or an optical link

    • Operational Status—Whether the link is active (up) or inactive (down). Click in the first cell in the Operational Status column to open the drop-down menu and select the type of operational status that you want as the filter for viewing for the links.
