OPERATION AND APPLICATION

Performance Statistics
The REPORT NETWORK MANAGER SECONDARY STATISTICS and
REPORT NETWORK MANAGER NETWORK STATISTICS commands are
provided as network diagnostic aids for locating bottlenecks or faulty
secondaries.
The
REPORT
NETWORK
MANAGER
SECONDARY
STATISTICS command, code 37, returns statistics for a specific secondary
device. These statistics are counters reflecting the communications between the
Network Manager and the secondary.
Each transaction will update the counters until their maximum value is
reached. Then the command must be issued to reset the counters. You may want
to reset the counters before beginning the diagnostic period so that the counts
start at the zero baseline.
The second command, REPORT NETWORK MANAGER NETWORK
STATISTICS — code 38, returns statistical counters for an specific media
channel. The counts reflect the activity between the Network Manager and all
secondary addresses. Like the secondary statistics counters, these counters are
not incremented after reaching their maximum value and must be reset
explicitly with the special command sequence.
The REPORT HIU STATUS command returns the connection status of the HIU
and statistics on network performance. The statistics are counts for Network
Manager to HIU communications. The counters are not updated after reaching
their maximum value and must be explicitly reset.
