Manages policies or tunnels that become disconnected from the system following synchronization events. It provides specialized tools and procedures to identify these orphaned items and restore their manageability, ensuring that all network services remain under proper administrative control.
Orphaned TE policies refer to any PCE-initiated SR-TE policies (including SRv6, SR-MPLS, and Tree-SID) or RSVP-TE tunnels that were created in the Crosswork Network Controller after the last cluster data synchronization. These orphaned policies can occur following a switchover in a High Availability setup or after a backup and restore operation. After a switchover, the system automatically checks for any orphaned TE policies or tunnels.
When orphaned TE policies or tunnels are detected, you can view their details but cannot modify them, as they were not part of the last data synchronization. The Crosswork Network Controller will raise an alarm when it identifies orphaned TE policies, which can be viewed under .
To help manage these orphans, Crosswork Network Controller provides APIs to list and clear them:
-
To retrieve a list of orphaned SR-TE policies or RSVP-TE tunnels, use the following APIs with the parameter
is-orphan=Trueand the default actionGET:-
cisco-crosswork-optimization-engine-sr-policy-operations:sr-datalist-oper -
cisco-crosswork-optimization-engine-rsvp-te-tunnel-operations:rsvp-te-datalist-oper
-
-
To make orphaned policies or tunnels manageable again, perform a
SAVEaction for the corresponding URL and policy type.
