Opened: Aug 08, 2022

Severity: 3-Major

Symptoms

An ASM policy is suddenly detached from a virtual server and deactivated.

Impact

Inactive policy is synced to the peer, resulting in ASM being unassigned from the Virtual Server.

Conditions

-- sync-only device group. -- ASM sync enabled. -- A policy is used on device ASM-A (attached to virtual server/device group). -- The same policy is not used on device ASM-B (not attached to virtual server/device group).

Workaround

To prevent Policy Sweeper from deactivating any ASM policy, create a non-functioning device group and attach the unused ASM policies to that device group.

Fix Information

None
