What is sifRingDrops?

This read-only Counter, valid only for 802.5 Token Ring ports, reports the number of times the ring left the open state. An administrator treats frequent occurrences as a sign of a cabling or MAU problem on that specific ring. For example, the admin sees sifRingDrops incrementing repeatedly on a Token Ring port and suspects a failing MAU or a station improperly inserting or removing itself from the ring.
