EtherHaul System Statistics
The EtherHaul system uses advanced RF and Ethernet counters to provide real -time
performance statistics for radio transmission activities, Ethernet ports, and VLAN traffic.
The following statistics enable quick analysis of system and component performance in
support of troubleshooting and diagnostics.
Hint:
For more details on system statistics, refer to
Monitoring the System
on page 119.
10.4.1 RF Statistics
Check RF statistic counters to identify radio errors and check the radio status history.
The RF statistics consist of real time statistic counters since the last time the counters
were cleared.
The RF transmission quality indicators are
rf in-errored-pkts, rf in-lost-
pkts
and
rf-in-errored-octets
. A rise in these indicators indicates radio errors.
No errors in these indicators indicates that the radio link is operating without errors.
Radio errors observed in these indicators do not mean necessarily frame -loss on the
Ethernet service. The ARQ (Automatic Repeat reQuest) algorithm uses selective repeat
(retransmission) to eliminate radio BER.
The
arq-in-loss
and
arq-out-loss
will indicate frame-loss over the radio that will
be noticed by the Ethernet service
For detailed explanations of all RF statistics, refer to
