What is protectionActiveCounter?

ACMIB::protectionActiveCounter tracks how many times a backup protection card has transitioned to the active role, incrementing each time it takes over traffic handling. A network engineer monitors this counter to detect excessive failovers, which may indicate intermittent hardware problems or network instability. For example, if this counter suddenly jumps from 3 to 10 in an hour, it signals the backup card is activating more often than normal, warranting investigation.
