Using Circuit-level Protocol Prioritization
2-21
Parameter: Prioritization Algorithm Type
Default: BANDWIDTH ALLOCATION
Options: BANDWIDTH ALLOCATION | STRICT
Function: Selects the dequeuing algorithm that protocol prioritization uses to drain
priority queues and transmit traffic. With strict dequeuing, the router
always transmits traffic in the high-priority queue before traffic in the
other queues. With bandwidth allocation dequeuing, the router transmits
traffic in a queue until the utilization percentage for that queue is reached,
and then the router transmits traffic in the next-lower-priority queue. (You
configure the percentages for bandwidth allocation by setting the Hiqh
Queue, Normal Queue, and Low Queue Percent Bandwidth parameters.)
Instructions: Accept the default of BANDWIDTH ALLOCATION or select STRICT.
MIB Object ID: 1.3.6.1.4.1.18.3.5.1.4.1.1.24
Parameter: High Queue Percent Bandwidth
Default: 70
Range: 0 to 100 percent
Function: If you select the bandwidth allocation dequeuing algorithm, this
parameter specifies the percentage of the synchronous line’s bandwidth
allocated to traffic that has been sent to the high-priority queue. When you
set this parameter to a value less than 100, each time the percentage of
bandwidth used by high-priority traffic reaches this limit, the router
transmits traffic in the normal- and low-priority queues, up to the
configured percentages for those priority queues.
Instructions: Specify the percentage of the line’s bandwidth allocated for high-priority
traffic. The High Queue Percent Bandwidth, Normal Queue Percent
Bandwidth, and Low Queue Percent Bandwidth values must total 100.
