Command Reference

12.0(3)T

corrected Number of error packets received through this upstream interface

that were corrected.

uncorrectable Number of error packets received through this upstream interface

that could not be corrected.

noise Number of upstream packets corrupted by line noise.

microreﬂections Number of upstream packets corrupted by microreﬂections.

Guaranteed-rate service queue depth Number of bandwidth requests queued up in the Guarantee-rate

queue. This queue is only available to modems that have a reserved

minimum upstream rate in their Class of Service.

Best-effort service queue depth Number of bandwidth requests queued up in the Best-effort queue.

This queue is available to all modems that do not have any reserved

rate on the upstream.

Total Modems On This Upstream

Channel

Number of cable modems currently sharing this upstream channel.

This ﬁeld also shows how many of these modems are active.

Current Total Bandwidth Reserved Total amount of bandwidth reserved by all modems sharing this

upstream channel that require bandwidth reservation. The Class of

Service for these modems speciﬁes some non-zero value for the

guaranteed-upstream rate. When one of these modems is admitted

on the upstream, this ﬁeld value is incremented by this

guaranteed-upstream rate value.

Current Admission Control Status 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 will be admitted by the CMTS

regardless of how much aggregate bandwidth is actually available.

Users enable admission control via the admission control CLI.

Percentage of Oversubscription Amount of oversubscription to allow on this upstream channel.

Oversubscription is expressed as a percentage of the raw capacity

of the channel. In the example shown, an oversubscription rate of

200% on a 2.56 Mbps channel allows the cumulative bandwidth

reservation on this channel to reach 5.12 Mbps before modems

conﬁgured with non-zero reserved upstream rates are denied

service.

Reservation Limit (with

Oversubscription)

Maximum cumulative bandwidth reservation allowable before

rejecting new modems. In the example shown, this reservation limit

with oversubscription is 5.12 Mbps.

Last Minislot Stamp

(current_time_base)

Indicates the current minislot count at the CMTS. FLAG indicates

the timebase reference. This ﬁeld is used only by developers.

Last Minislot Stamp

(scheduler_time_base)

Indicates the furthest minislot count allocated at the indicated time.

FLAG indicates the timebase reference. This ﬁeld is used by

developers.
