I try to configure qos profile configure for per c-vid in untagged traffic, but not success. Is there any way to configure qos profile for untagged traffic in per c-vid.

 

I write policy as below and appply to the ingress interface as below.

 

entry replace_DSCP_46 {
if match vlan-id 54 {
} then {
qosprofile qp6;
replace-dscp;
}
}

entry replace_DSCP_38 {
if match vlan-id 56 {
} then {
qosprofile qp5;
replace-dscp;
}
}

entry replace_DSCP_26 {
if match vlan-id 58 {
} then {
qosprofile qp4;
replace-dscp;
}
}

Hi,

 

I didn’t play with it so far, but VID 0 theoretically allows to apply a 802.1Q header to a frame and have 802.1p in TCI field then. Maybe this.

 

Hope that helps,

Tomasz

Have you associated the respective DSCP code-points with those QOS profiles?

# configure diffserv replacement <qos-profile> code-point <value>
