(viewed on COM2)
is shown below:
Figure

Example of Statistics Screen
The
left
column shows the number of
ARCNET
messages received
by the router. The
right
column shows the number of
Ethernet
messages received by the router. The Idle counters are incremented
when the router
has no
messages to process and is
idle. When
ever
statistics
are
display
ed
, the Idle counter
increments continuously.
Note:
Use the Idle counter only as an indication that the router is
running. It does not provide an accurate estimate of percent
idle time for the router.
The
Normal
message counters indicate the number of Normal
(non-broadcast) messages received by the router. The
Broadcast
message counters
report
the number of Broadcast
messages received
by the router
and
destined for all nodes
in Metasys. The
Retry
message counter tracks the number of RTOS (Real Time Operating
System) messages retransmitted;
low numbers reflect stable N1
communications.
Invalid
counters
report
the number of Invalid messages
received.
Invalid message
s
contains invalid
address
es
.
These
counters
should
always be zero during normal
operation
— otherwise
, the latest
Invalid message
is
display
ed
on the screen below the
statistics.
The ARCNET
Failure
counter indicates the number of times an
ARCNET message could not be delivered to its destination due to
Ethernet errors. While this counter should normally be zero, it will
increment if one of the other
JC-MER-CXB unit
s is offline.
