Release Information

Statement introduced in Junos OS Release 19.3R2 on MX Series routers (MX240, MX480 and MX960) running Next Gen Services with the MX-SPC3 services card.


Configure a policy in a services CoS rule. The policy specifies Differentiated Services (DiffServ) code point (DSCP) marking and forwarding-class assignment for packets that are processed by a service set. The policy identifies the matching conditions for packet source and destination addresses and for packet applications, and the actions to take on those packets. A CoS rule can include multiple policies.

The service set that the CoS rule is assigned to must include at least one stateful firewall rule or NAT rule, or CoS does not work. Only stateful firewall and NAT rules can be used with CoS rules in a service set.
