15.3(3)S1.9

Description (partial)

Symptom:
When there is a policy change (either KS or GM)  in Pre-PAL,  the Cisco ASR 1000 router registers again. This is because in TCAM, SA cannot be inserted or moved. An ACL merge was done in the ACE driver, and reregistration was triggered from there.

Post-PAL, ACL merge intelligence is moved to a control plane. ACL is changed and change flow priority occurs. The SA is inserted with second priority which cannot be handled by the device.

Conditions:
This symptom occurs when an ACL changes on the KS or the GM.
