Viewing Radio Statistics
You can display radio statistics using the Web EMS or the CLI. Radio statistic counters
can be used to identify radio errors. When there are no errors on
In Errored Octets
,
In
Errored Packets
, and
In Lost Packets
in the current radio statistics, this indicates that
the radio link is operating without errors.
Radio errors observed in these indicators do not necessarily indicate 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
indicate frame-loss over the radio that can be
noticed by the Ethernet service.
