Using the TRMMIM Hub View

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.

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.
