Example: Configuring a CoS Policy for IPv6 Packets

1. Define a new classifier of type DSCP IPv6.

   [edit class-of-service]

   classifiers {

   dscp-ipv6 core-dscp-map {

   forwarding-class best-effort {

   loss-priority low code-points 000000;

   }

   forwarding-class assured-forwarding {

   loss-priority low code-points 001010;

   }

   forwarding-class network-control {

   loss-priority low code-points 110000;

   }

   }

   }

2. Define a new rewrite rule of type DSCP IPv6.

   [edit class-of-service]

   rewrite-rules {

   dscp-ipv6 core-dscp-rewrite {

   forwarding-class best-effort {

   loss-priority low code-point 000000;

   }

   forwarding-class assured-forwarding {

   loss-priority low code-point 001010;

   }

   forwarding-class network-control {

   loss-priority low code-point 110000;

   }

   }

   }

3. Assign the classifier and rewrite rule to a logical interface.

   [edit class-of-service]

   interfaces {

   so-2/0/0 {

   unit 0 {

   classifiers { # Both dscp and dscp-ipv6 classifiers on this interface.

   dscp default;

   dscp-ipv6 core-dscp-map;

   }

   rewrite-rules { # Both dscp and dscp-ipv6 rewrite rules on this interface.

   dscp default;

   dscp-ipv6 core-dscp-rewrite;

   }

   }

   }

   }
