Field Description
Avg upstream channel utilization Average percent of the upstream channel bandwidth being used.
Avg percent contention slots Average percent of slots available for CMs to request bandwidth
using contention mechanisms. Also indicates the amount of unused
capacity in the network.
Avg percent initial ranging slots Average percent of slots in the initial ranging state.
Avg percent minislots lost on Average percent of slots that were lost because a MAP interrupt
late Maps
was too late.
Current Total Bandwidth Total amount of bandwidth reserved by all CMs sharing this
Reserved
upstream channel that require bandwidth reservation. The CoS for
these CMs specifies some nonzero value for the
guaranteed-upstream rate. When one of these CMs is admitted on
the upstream, this field value is incremented by this
guaranteed-upstream rate value.
CIR admission control Indicates the status of admission control on the upstream channel.
ENFORCED status allows users to enable admission control on a
per-port basis. This controls how limited bandwidth is allocated.
NOT ENFORCED status indicates that there is no admission
control. Every modem that registers with a class of service
specifying a minimum upstream rate is admitted by the CMTS,
regardless of how much aggregate bandwidth is actually available.
Users enable admission control via the admission control
command-line interface (CLI).
Subscription Level Amount of oversubscription to allow on this upstream channel, as
configured with the cable upstream admission-control command.
Oversubscription is expressed as a percentage of the raw capacity
of the channel. In the example shown, an oversubscription rate of
200 percent on a 2.56 Mbps channel allows the cumulative
bandwidth reservation on this channel to reach 5.12 Mbps before
CMs configured with nonzero reserved upstream rates are denied
service.
Reservation Limit (with Maximum cumulative bandwidth reservation allowable before
Oversubscription)
rejecting new CMs. In the example shown, this reservation limit
with oversubscription is 5.12 Mbps.
Admission requests rejected Number of CMs that attempted to register on this interface but were
rejected because of the admission control policy that has been
configured with the cable upstream admission-control command.
Last Minislot Stamp
Indicates the current minislot count at the CMTS. FLAG indicates
(current_time_base)
the timebase reference. This field is used only by developers.
Last Minislot Stamp
Indicates the furthest minislot count allocated at the indicated time.
(scheduler_time_base) FLAG indicates the timebase reference. This field is used by
developers.
