LOCAL MANAGEMENT

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.
