About the Maintenance Tab

You can use the Maintenance tab in the network information table to schedule maintenance events for network elements, so that you can perform updates or other configuration tasks. Maintenance events are planned downtimes which occur at specific future date and time. During a scheduled maintenance event, the selected elements are considered logically down, and the system reroutes the LSPs around those elements. After the maintenance event is completed, by default, all LSPs that were affected by the event are reoptimized.


Paragon Pathfinder only attempts to reoptimize PCE-initiated and PCC-delegated LSPs (not PCC-controlled LSPs).
