Scheduling an automatic pending discovery determines how often the MPLS Topology Server attempts to discover MPLS topology by probing the devices on the Pending Elements list.

The parameters that control automatic pending discovery are located on the Topology tab of the Domain Manager Administration Console. By default, automatic pending discovery is disabled.

The pending discovery interval is counted from the time when the MPLS Topology Server is started. So, if the pending discovery interval is set to six hours and the MPLS Topology Server is started at 5 A.M., the pending discovery will occur every six hours thereafter, that is, at 11 A.M., at 5 P.M., at 11 P.M., and so on.

To enable automatic pending discovery and to specify a pending discovery interval:

  1. Attach the Domain Manager Administration Console to the MPLS Topology Server.

    Instructions for opening the Domain Manager Administration Console are presented in “Open the Domain Manager Administration Console” on page 137.

  2. In the left panel of the Domain Manager Administration Console, click the MPLS Topology Server name to display a multiple-tab window in the right panel of the console.

  3. Select the Topology tab.

  4. Click the Enable Discovery Pending checkbox.

  5. Type a value in the Interval field for pending discovery and select a time interval (Seconds, Minutes, Hours, or Days) from the list. Ensure that the interval is equal to or greater than five minutes.

  6. Click Apply.
