Parameter Description
min-thresh The minimum threshold the queue depth (as a percentage) where WRED starts marking and
dropping trac.
max-thresh The maximum threshold is the queue depth (as a percentage) above which WRED marks /
drops all trac.
drop-
probability
The percentage probability that WRED will mark/drop a packet, when the queue depth is at
the maximum threshold. (The drop probability increases linearly from 0 just before the
minimum threshold, to this value at the maximum threshold, then goes to 100% for larger
queue depths).
no random-detect queue-parms
Use this command to set the WRED configuration back to the default.
Format no random-detect queue-parms queue-id-1 [queue-id-2 … queue-

trac-shape
This command specifies the maximum transmission bandwidth limit for the interface as a whole. The
bandwidth values are from 0-100 in increments of 1. You can also specify this value for a range of
interfaces or all interfaces. Also known as rate shaping, trac shaping has the eect of smoothing
temporary trac bursts over time so that the transmitted trac rate is bounded.

show classofservice dot1p-mapping
This command displays the current Dot1p (802.1p) priority mapping to internal trac classes for a
specific interface. The unit/slot/port parameter is optional and is only valid on platforms that support
independent per-port class of service mappings. If specified, the 802.1p mapping table of the interface
