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).
RING INFORMATION
Ring Information provides ring status information.
Active Monitor Addr
Displays the MAC address of the active monitor. The active
monitor initiates recovery procedures from various error
situations.
Ring Status
This field lists the current status of the ring being monitored by
the TRXI. TRXI displays the following ring status conditions:
