MX# clear qos
success: change accepted.
The following command resets the mapping used to classify packets with DSCP value 44:
MX# clear qos dscp-to-qos-map 44
success: change accepted.
clear qos-profile
Clears a QoS profile from the configuration.
Syntax clear qos-profile profile-name
Defaults None
Access Enabled
History Introduced in MSS Version 6.2.
Examples To clear a QoS profile with the profile name, best_voice, from the MSS configuration,
use the following command:
MX# clear qos-profile best_voice
success: change accepted
set qos cos-to-dscp-map
Changes the value that MSS maps an internal QoS value when marking outbound packets.
Syntax set qos cos-to-dscp-map level dscp dscp-value
Defaults The defaults are listed by the show qos command.
Access Enabled.
History Introduced in MSS Version 4.1.
Examples The following command maps internal CoS value 5 to DSCP value 50:
MX# set qos cos-to-dscp-map 5 dscp 50
warning: cos 5 is marked with dscp 50 which will be classified as cos 6
If the change results in a change to CoS, MSS displays a warning message indicating the change.
In this example, packets receiving CoS 5 upon ingress are marked with a DSCP value equivalent
to CoS 6 upon egress.
