Chapter 11 Managing Packet Queue Congestion
On the PRE3 and PRE4, the supported random-detect commands specify the aggregate profile for
•
the queue. To configure a default drop profile for a queue, the random-detect basis command is
used (for example, random-detect dscp-based aggregate command). The random-detect
discard-class-based, random-detect atm-clp-based and random-detect atm-clp-based
commands do not have an aggregate form of the command on the PRE3 and PRE4.
If you do not specify any arguments, WRED uses the default IP precedence in the WRED calculations.

Controlling Congestion Using Weighted Random Early Detection
Description
A number that indicates the drop eligibility of a
packet based on the differentiated services code
point. Value numbers are from 0 to 63.
A number that indicates the drop eligibility of a
packet based on the IP precedence level. Valid
values are from 0 to 7. Typically, 0 represents low
priority traffic that can be aggressively managed
(dropped) and 7 represents high priority traffic.
A number that indicates the drop eligibility of a
packet based on the discard-class. Valid values
are from 0 to 7.
