Description
Total amount of bandwidth reserved by all CMs sharing this
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.
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).
Amount of oversubscription to allow on this upstream channel, as
configured with the
cable upstream admission-control
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.
Maximum cumulative bandwidth reservation allowable before
rejecting new CMs. In the example shown, this reservation limit
with oversubscription is 5.12 Mbps.
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
Maximum virtual bandwidth of this capacity, in bits per second
(bps), when admission control is enabled.
Indicates the current minislot count at the CMTS. FLAG indicates
the timebase reference. This field is used only by developers.
Indicates the furthest minislot count allocated at the indicated time.
FLAG indicates the timebase reference. This field is used by
developers.
Number of Unsolicited Grant Service (UGS) flows that are
currently active on the upstream.
Maximum number of UGS service flows, minimum number of
UGS service flows, and average number of UGS service flows that
have been allocated on the upstream over the last hour and last five
minute period.
