LOCAL MANAGEMENT

Burst Errors

Displays the total burst errors detected by the TRXI. Burst Errors are the absence of clocking signals at a node’s receiver. This error normally occurs when stations enter or leave the ring with the absence of phantom current.

This error can also indicate a problem with the receiver of the reporting node, or the transmitter of its NAUN, or the cabling and hub hardware between them.

AC Errors

Displays the total Address Recognized/Frame Copied errors. This indicates that the reporting NAUN is faulty. The node cannot set the address recognized indicator and/or frame copied indicator bits in the frame which it has copied. This leaves the downstream node with an incorrect NAUN address.

Abort Transmit Errors

Displays the total abort delimiter frames transmitted by a station. This indicates that either the reporting node has detected an error on itself, or there is an error with its NAUN, or the cabling and wiring hubs between them.

Internal Errors

Displays the total internal errors detected by the adapter’s hardware and/or firmware. These errors cause the adapter to remove itself from the ring and indicates a problem with the adapter hardware or firmware (possibly an inoperable chipset, timers, or counters).

Active Monitor Addr

Displays the MAC address of the active monitor. The active monitor initiates recovery procedures from various error situations.
