Frame Copied Errors
Displays the total number of Frame Copied Errors. These errors
occur when a station finds a frame with its address as the
destination, but finds the address recognized indicator bits not
set to zero. This indicates a possible duplicate address.
Rcvr Congestion Errors
Displays the total number of Rcvr Congestion Errors. This
indicates a station is receiving/repeating a frame and recognizes
a frame addressed to it, but has no buffer space available for the
frame.
Token Errors
Displays the total number of Token Errors. Token Errors occur
when an active monitor does not see a token circulating on the
ring before its TVX (Timer, Valid Transmission) time expires
(e.g. a lost frame error has occurred), or sees a recirculating
frame or token. The active monitor is responsible for purging the
ring and issuing a new token.
Frequency Errors
Displays the total number of frequency errors. This indicates
that the frequency of the incoming signal deviates excessively
from the adapter’s onboard crystal oscillator. It could indicate an
error in this node’s oscillator, the active monitor, or any node in
between. When the node detects a frequency error, it enters the
monitor contention process.
Total
Displays a running total of statistics beginning from the TRXI’s
last power-on.
Accumulate
Initiates a new statistic count. The TRXI begins totaling
statistics after you select accumulate.
Delta
Displays the total statistics beginning at the last screen Refresh.
Refresh99sec
Displays the time interval between screen counter updates. You
can choose refresh intervals in increments of 3 seconds, with the
maximum interval being 99 seconds.
