Module: POWERHUB-ATM-MIB
OID (symbolic): POWERHUB-ATM-MIB::alAtmPreviousAMA

Node type: OBJECT-TYPE

Description: The AMA that is actually being used before link down or cut over. The initial value is notset.
What is alAtmPreviousAMA?
This value records which AMA, primary or backup, was actively in use immediately before the last link-down event or cutover on this slot. Admins use it, alongside alAtmAMAActualUse, to reconstruct the sequence of a failover event, showing what was active right before the switch happened. After a failover, seeing alAtmPreviousAMA report primary while alAtmAMAActualUse now shows backup confirms a primary-to-backup cutover just occurred on that slot.
