Reference Guide

• dot1p values — (Optional) Enter either single, comma-delimited, or a hyphenated range of dot1p values (0
to 7).
Default 0
Command Mode TRUST-MAP
Usage Information If the trust map does not dene dot1p values to any trac class, those ows are mapped to the default trac
class (0). If some of the dot1p values are already mapped to an existing trac class, you will receive an error. You
should have a 1:1 dot1p to trac class mapping for PFC-enabled CoS values. You should also have a common dot1p
trust map for all interfaces using DCB. The no version of this command returns the value to the default.
Example
OS10(conf-tmap-dot1p-qos)# qos-group 5 dot1p 5
Supported Releases 10.3.0E or later
qos-group dscp
Congures a dscp trust map to the trac class.
Syntax
qos-group tc-list [dscp values]
Parameters
• qos-group tc-list — Enter the trac single value class ID (0 to 7).
• dscp values — (Optional) Enter either single, comma-delimited, or a hyphenated range of dscp values (0
to 63).
Default 0
Command Mode TRUST-MAP
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 this queue (0 to 8911). Defaults:
• 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 enable dynamic shared buer threshold (0 to 10). Defaults:
