forwarding-class (CoS Host Outbound Traffic)


Hierarchy Level


Specify the name of the forwarding class to which host outbound traffic is assigned on all egress interfaces. The output queue associated with the forwarding class must be properly configured on all interfaces. In the case of a restricted interface, the traffic flows through a restricted queue.

For egress interfaces hosted on MX Series routers, M120 routers, or Enhanced III FPCs in M320 routers, both Routing Engine sourced traffic and distributed protocol handler traffic are affected. For all other egress interfaces, only Routing Engine sourced traffic is affected.

This statement does not affect transit traffic or incoming traffic.


If you do not configure an output queue for host outbound traffic, the router uses the default queue assignments for host outbound traffic.
