Monitoring Hub Performance

2-23

Using the TRMMIM Hub View

Errors

The total number of errors detected by the selected station port since the device
was last reset.

Frames

The total number of frames transmitted by the selected station port.

Bytes

The total number of bytes transmitted by the selected station port.

Line

The count of line errors detected by the selected station. This error indicates a
non-data bit between the starting and ending delimiters of data, or a frame check
sequence error.

Burst

The count of burst errors detected by the selected station port. This error indicates
a bit information-encoding error where there are no transitions between 0 and 1
over five half-bit times.

AC

The number of frames containing errors in the A or C bits detected by the selected
station port.

Abort

The number of times the selected station has transmitted abort sequences during
transmission.

Internal

The number of recoverable internal errors detected by the selected port,
indicating that its attached station is in marginal operating condition.

Lost Frames

The number of frames that the selected station has transmitted that have not
returned because the Timer – Return to Repeat (TRR) timer has expired.

Congest

The number of times the selected station has not been able to copy a frame
addressed to it because of a lack of internal buffering.

NOTE

When a device is reset, statistics windows and/or statistics displays in the Hub View may
display very large numbers for one polling interval. This is due to the resetting of the
counters.
