Reference Guide

Usage Information If the trust map does not dene dscp values to any trac class, those ows are mapped to the default trac class
(0). If some of the dscp values are already mapped to an existing trac class, you will receive an error. The no
version of this command returns the value to the default.
Example
OS10(conf-tmap-dscp-qos)# qos-group 5 dscp 42
Supported Releases 10.3.0E or later
queue-limit
Congures static or dynamic shared buer thresholds.
Syntax
queue-limit {queue-len value | thresh-mode [dynamic threshold-alpha-value |
static threshold-value]}
Parameters
• queue-len value — Enter the guaranteed size for queue (0 to 8911).
– 45 KB (10G)/111 KB (40G) if queue is priority ow control enabled
– 2 KB (10G)/8 KB (40G) if queue is lossy/link-level ow control
– If this is a priority ow-control queue, this conguration is invalid
– Only supported for POLICY-MAP-CLASS-MAP (pmap-c-queue) mode
• thresh-mode — (Optional) Buer threshold mode.
• dynamic thresh-alpha-value — (Optional) Enter the value indexes to calculate the shared threshold
to the enabled dynamic shared buer threshold (0 to 10). Defaults:
– 0 = 1/128
– 1 = 1/64
– 2 = 1/32
– 3 = 1/16
– 4 = 1/8
– 5 = 1/4
– 6 = 1/2
– 7 = 1
– 8 = 2
– 9 = 4
– 10 = 8
• static thresh-value — (Optional) Enter the static shared buer threshold value in Bytes.(1 to 65535).
Default
Not congured
Command Mode POLICY-MAP-CLASS-MAP
Usage Information Use the queue-len value parameter to set the minimum guaranteed queue length for a queue. The no version
of this command returns the value to the default.

threshold 10
OS10(conf-cmap-nqos-c)# queue-limit 150
