You can also select Unusual Token Ring Errors from the CATEGORY box to display additional information.

# Beacon Frames (dot5StatsHardErrors)

# Soft Errors (dot5StatsSoftErrors)

Indicates the number of soft errors or recoverable errors (by the MAC protocol) that have been detected.

# Congestions (dot5StatsReceiveCongestions)

This counter increments when there is not enough buffer space to receive an incoming frame.
