Traffic Redirecting
Traffic redirecting is the action of redirecting the packets matching the specific match criteria to a certain
location for processing.
Currently, the following four traffic redirecting actions are supported:
z
Redirecting traffic to the CPU: redirects packets which require processing by CPU to the CPU.
z
Redirecting traffic to an interface: redirects packets which require processing by an interface to the
interface. Note that this action is applicable to only Layer 2 packets, and the target interface should
be a Layer 2 interface.
z
Redirecting traffic to the next hop: redirects packets which require processing by an interface to the
interface. This action is applicable to only Layer 3 packets.
