CoS for NAT Services on ACX Series Routers

For packets that go through NAT services, the classification is done when the packet enters the router, and the resulting forwarding class and the packet loss priority are preserved when the packet goes through the inline services interface. When the packet exits the router through a physical interface, the queuing, scheduling, and rewrite rules configured on the egress physical interface are applied on the basis of the forwarding class and packet loss priority derived during ingress.

Note:

CoS for NAT services is not applicable on ACX5048 and ACX5096 routers.

Queuing and scheduling are supported on the inline services interface to handle congestion at the inline services interface. Congestion at inline services interface is possible when the interface is oversubscribed. In this case, you would need to selectively drop packets based on the packet's forwarding class and packet loss priority. To drop packets based on the packet's forwarding class and packet loss priority, scheduler map configurations are supported on the inline services interface.

Note:

In ACX Series routers, you cannot configure classification and rewrite policies on the inline services interface.
