Default DSCP and DSCP IPv6 Classifiers

To enable the default DiffServ code point (DSCP) classifier, include the default statement at the [edit class-of-service interfaces interface-name unit unit-number classifiers dscp] hierarchy level.

To enable the default DSCP IPv6 classifier, include the default statement at the [edit class-of-service interfaces interface-name unit unit-number classifiers dscp-ipv6] hierarchy level.

Note:

If you deactivate or delete the dscp-ipv6 statement from the configuration, the default IPv6 classifier is not activated on the M5, M10, M7i, M10i, M20, M40, M40e, and M160 routing platforms. As a workaround, explicitly specify the default option to the dscp-ipv6 statement.

Table 1 shows the forwarding class and packet loss priority (PLP) that are assigned to each well-known DSCP when you apply the explicit default DSCP or DSCP IPv6 classifier.
