What is oamGuard?
This timestamp records the last time an OAM (Operation, Administration, and Maintenance) cell was sent or received on a particular switch board, measured as system uptime. OAM cells are heartbeat-like messages that verify the board is functioning and connected to the fabric. Network operators monitor this value to detect if a board has become isolated or stopped communicating, triggering automatic switchover in redundant systems.
