Report Network Bandwidth Allocation — 36

The

REPORT NETWORK BANDWIDTH ALLOCA

TION

command returns the

relative amount of network bandwidth being used by a specific HIU. The

counters

stop incrementing when they reach their maximum value and must be

explicitly

reset. The first set of counters corresponds to the counts for all HIUs

and the second set for the specified HIU. The ratio of the HIUs counts to the

counts

for all HIUs gives a relative indication of the HIUs bandwidth.

Command:
