Description: The number of times the interface has sensed that it is the only station on the ring. This will happen if the interface is the first one up on a ring, or if there is a hardware problem.

What is a3ComSysTokenRingPortSingles?

Counts instances when the interface detects it is the only station on the ring, which occurs at startup or indicates a hardware fault. A network engineer uses this to identify if a device is isolated or if a catastrophic ring break has occurred. Example: a counter of 1 is normal at startup; multiple increments suggest intermittent connectivity loss.

Examples
