show interfaces fddi Field Descriptions (continued)
Field
Description
ring operational
When the ring is operational, the displayed value will be
the negotiated token rotation time of all stations on the
ring. Operational times are displayed by the number of
hours/minutes/seconds the ring has been up. If the ring is
not operational, the message “ring not operational” is
displayed.
Configured tvx
Transmission timer.
LER
Link error rate.
Upstream
|
downstream
neighbor
Displays the canonical MAC address of outgoing
upstream and downstream neighbors. If the address is
unknown, the value will be the FDDI unknown address
(
0x00 00 f 8 00 00 00
).
Last input
Number of hours, minutes, and seconds since the last
packet was successfully received by an interface. Useful
for knowing when a dead interface failed.
output
Number of hours, minutes, and seconds since the last
packet was successfully transmitted by an interface.
output hang
Number of hours, minutes, and seconds (or never) since
the interface was last reset because of a transmission that
took too long. When the number of hours in any of the
“last” fields exceeds 24 hours, the number of days and
hours is printed. If that field overflows, asterisks are
printed.
Last clearing
Time at which the counters that measure cumulative
statistics (such as number of bytes transmitted and
received) shown in this report were last reset to zero. Note
that variables that might affect routing (for example, load
and reliability) are not cleared when the counters are
cleared.
*** indicates the elapsed time is too large to be displayed.
0:00:00 indicates the counters were cleared more than 231
ms (and less than 232 ms) ago.
Queueing strategy
First-in, first-out queuing strategy (other queueing
strategies you might see are priority-list, custom-list, and
weighted fair).
Output queue, input
queue,
drops
Number of packets in output and input queues. Each
number is followed by a slash, the maximum size of the
queue, and the number of packets dropped due to a full
queue.
