What is swUnitNumOfUnit?

swUnitNumOfUnit reports the current number of units actively present in the stack or chassis. Admins poll this to confirm the expected number of stack members are present and detected, useful for quickly noticing if a unit has dropped out of the stack. For example, a drop in swUnitNumOfUnit from 4 to 3 would alert an admin that one stack member has gone offline or been physically removed.
