Class based forwarding (CBF) is a means for steering network traffic into colored tunnels based on one or more fields of the ingress traffic. Rephrased, CBF is forwarding of traffic based on “classes” which are derived from fields in the ingress packet headers and policies provisioned on the router.

Rate limiting of mirrored traffic provides support to control the rate of mirrored traffic that can egress the switch. This feature can be applied to both regular port mirroring and encapsulated mirroring (e.g., mirroring to GRE tunnel), depending on the platform.

The ‘redirect’ action used in TCAM profile has lower priority than system rules, if packets match both TCAM rule using ‘redirect’ action and system rules. Hence ‘redirect’ action does not take effect on these packets.
