mls qos map premark-dscp to
Overview
This command configures the premark-dscp map. It is used when traffic is
classified by a class-map that has
trust dscp
configured. Based on a lookup DSCP,
the map determines new QoS settings for the traffic.
The
no
variant of this command resets the premark-dscp map to its defaults. If no
DSCP is specified then all DSCP entries will be reset to their defaults.
This command is supported in Software Version 5.4.3A-1.x and later.
Syntax
mls qos map premark-dscp <
0-63
> to [new-queue <
0-4
>]
no mls qos map premark-dscp [<
0-63
>]
Mode
Global Configuration
Usage
With the
trust dscp
command set, the
mls qos map premark-dscp
command
enables you to specify the queue for packets.
When
trust dscp
is enabled on a port, the switch cannot use the CoS (802.1p
priority) value to determine queue settings for traffic egressing that port.
Therefore, non-IP packets will not be prioritized on that port. Non-IP packets will all
go into queue 0.
NOTE
:
Example
To send packets to queue 2 if they have a DSCP of 34, use the commands:
awplus#
configure terminal
awplus(config)#
mls qos map premark-dscp 34 to new-queue 2
Example
To reset the entry for DSCP
1
use the command:
awplus#
configure terminal
awplus(config)#
no mls qos map premark-dscp 1
