Understanding DSCP IPv6 Rewrite Rules
After Junos OS CoS processing, a rewrite rule maps the forwarding class and loss priority after Junos OS CoS processing to a corresponding DSCP value specified in the rule. Typically, you use rewrite rules to alter the CoS values in outgoing packets to meet the requirements of the targeted peer.
You can use the CLI show command to display the configuration for the CoS classifiers. The following command shows the configuration of the default DSCP IPv6 rewrite rule:
user@host# show class-of-service rewrite-rule type dscp-ipv6 Rewrite rule: dscp-ipv6-default, Code point type: dscp-ipv6, Index: 32 Forwarding class Loss priority Code point best-effort low 000000 best-effort high 000000 expedited-forwarding low 101110 expedited-forwarding high 101110 assured-forwarding low 001010 assured-forwarding high 001100 network-control low 110000 network-control high 111000
