Beacon Statistics | Enterasys Networks MicroMMAC-T specification

Token Ring Statistics

Ring Purges

Displays the number of times the active monitor has purged the ring since the network was created, or since the MicroMMAC-T was last reset. This includes the purge at the end of the active monitor selection process. The count is not reset when the active monitor changes.

Total Frames

Displays the number of frames that have been transmitted on the ring.

Total KBytes

Displays the total number of kilobytes that have been transmitted on the ring. This number is the sum of all data bytes in each frame.

Beacon Statistics

A Beacon is transmitted when a hardware error is detected on the ring, including: wire faults, frequency errors, or ring signal loss.

Note that the Longest Beacon and Last Beacon fields are read from the device (Total update), and are not subject to Delta or Cumulative update options.

Beacon States

This field lists the count of beaconing occurrences on the ring.

Longest Beacon

This field lists the duration of the longest beaconing occurrence (not subject to Delta/Cumulative update).

Last Beacon

This field provides the duration of the last beacon (not subject to

Delta/Cumulative update).

Soft Error Fields

Line Errors

Displays the total number of line errors that the management station has detected. These are recorded when a receiving station detects a data corruption in a frame that was initially transmitted as a good frame, with the E bit (error flag) set at zero (0).

A power surge on the ring (line of transmission) may cause the data portion of a frame or token to be corrupted. The frame or token then may contain a non-data bit between the data start and end delimiters, or a Frame Check Sequence (FCS) error.
