cdxQosMaxUpBWExcessRequests The number of upstream bandwidth requests which exceeds
the maximum upstream bandwidth allowed for a service
defined in the Quality of Service profile associated with this
Sid. The request which exceeds the maximum upstream
bandwidth allowed will be rejected by the upstream's rate
limiting process using one of the rate limiting algorithm.
Note that the value of this counter cannot be directly used to
know the number of upstream packets that got dropped at the
MTA. A single upstream packet drop of a modem can result
in up to 16 increments in this counter, since the modem keeps
retrying and keeps getting bandwidth request drops at CMTS
if it has consumed its peak rate.
cdxQosMaxDownBWExcessPackets The number of downstream bandwidth packets which
exceeds the maximum downstream bandwidth allowed for a
service defined in the Quality of Service profile associated
with this Sid. The packet which exceeds the maximum
downstream bandwidth allowed will be dropped by the
downstream's rate limiting process using one of the rate
limiting algorithm.
cdxBWQueueNameCode The name code for the queue.
• cirQ: Committed Information Rate (CIR) type of service
• tbeQ: Tiered Best Effort (TBE) type of service
cdxBWQueueOrder The relative order of this queue to the other queues within the
cable interface. The smaller number has higher order. That is,
0 is the highest order and 10 is the lowest order. The
scheduler will serve the requests in higher order queue up to
the number of requests defined in
cdxBWQueueNumServedBeforeYield before serving
requests in the next higher order queue.
If there are n queues on this interface, the queue order will be
0 to n-1 and maximum number of requests defined as
cdxBWQueueNumServedBeforeYield in order 0 queue will
be served before the requests in order 1 queue to be served.
cdxBWQueueNumServedBeforeYield The maximum number of requests/packets the scheduler can
serve before yielding to another queue. The value 0 means all
requests must be served before yielding to another queue.
cdxBWQueueType The queuing type which decides the position of a
request/packet within the queue.
unknown (1): queue type unknown.
other (2): not fifo, and not priority.
fifo (3): first in first out.
priority (4): each bandwidth request has a priority and the
position of the request within the queue depends on its
priority.
