Applying DSCP and DSCP IPv6 Classifiers
You can apply classifiers on a physical interface by including the classifiers statement
at the [edit class-of-service interfaces interface-name] hierarchy level and specifying the
dscpand dscp-ipv6 classifier types:
[edit class-of-service interfaces interface-name]
classifiers dscp (classifier-name | default);
classifiers dscp-ipv6 (classifier-name | default) );
For ACX Series routers, you cannot apply separate DSCP and DSCP IPv6 classifiers for
IPv4 and IPv6 packets on a physical interface. Instead, classifier assignment works as
follows:
•
If you assign a DSCP classifier only, IPv4 and IPv6 packets are classified using the DSCP
classifier.
•
If you assign a DSCP IPv6 classifier only, IPv4 and IPv6 packets are classified using the
DSCP IPv6 classifier.
•
If you assign an IP precedence classifier only, IPv4 and IPv6 packets are classified using
the IP precedence classifier. In this case, the lower three bits of the DSCP field are
ignored because IPv4 precedence mapping requires the upper three bits only.
•
You can assign either DSCP, DSCP IPv6, or IPv4 precedence classifier types on a physical
interface.
•
You can configure either DSCP, DSCP IPv6, or IPv4 precedence rewrite rules on a
physical interface. The rewrite rule applies to both IPv4 and IPv6 packets.
•
If you assign either the DSCP or the IP precedence classifier in conjunction with the
DSCP IPv6 classifier, the commit fails.
