ASM Sync was designed to only request the ASM portion of the configuration if it recognizes that a peer has a newer configuration. This precludes the ability to 'roll back' changes on a device by pushing from the peer that still has the older configuration.


User is unable to 'roll back' changes on a device by pushing from the peer that has an older configuration.


Devices are set up in a Manual Sync ASM-enabled group.


Make a spurious change on the device that has an older config and then push the changes to the peer.

Fix Information

An older ASM configuration can now be manually pushed to a peer in a device group.
