15.15 pass-through-dscp
Command:
pass-through-dscp
no pass-through-dscp
Function:
Forbid the egress packets rewriting DSCP value.
Default:
The egress packets rewrite DSCP value.
Command mode:
Port Mode.
Usage Guide:
The egress packets can not rewrite DSCP value when configuring pass-through-dscp on the ingress.
This command may associate with other commands of QoS, such as mls qos trust command. After
QoS actions are valid, the egress packets save the original DSCP value.
Example:
Configuring ethernet port 1/0/1 to trust CoS value, i.e., classifying the packets according to CoS
value.
Switch(config)#interface ethernet 1/0/1
Switch(config-if-ethernet1/0/1)#mls qos trust cos
Switch(config-if-ethernet1/0/1)#pass-through-dscp
