Reference Guide
Usage Information If the trust map does not dene dscp values to any trac class, those ows are mapped to the default trac class
(0). If some of the dscp values are already mapped to an existing trac 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
Congures static or dynamic shared buer 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 conguration is invalid
– Only supported for POLICY-MAP-CLASS-MAP (pmap-c-queue) mode
• thresh-mode — (Optional) Buer threshold mode.
• dynamic thresh-alpha-value — (Optional) Enter the value indexes to calculate the shared threshold
to the enabled dynamic shared buer 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 buer threshold value in Bytes.(1 to 65535).
Default
Not congured
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.
Example
OS10(config)# policy-map type network-qos nqGlobalpolicy1

OS10(conf-cmap-nqos-c)# pause buffer-size 45 pause-threshold 30 resume-
threshold 10
OS10(conf-cmap-nqos-c)# queue-limit 150
Example (queue)
OS10(config)# policy-map type queuing pmap1
OS10(config-pmap-queuing)# class cmap1
