Traffic redirecting configuration
Traffic redirecting overview
Traffic redirecting is the action of redirecting the packets matching the specific match criteria to a certain
location for processing.
The following redirect actions are supported:
• Redirecting traffic to the CPU: redirects packets that require processing by the CPU to the CPU.
• Redirecting traffic to an interface: redirects packets that require processing by an interface to the
interface. Note that this action applies to only Layer 2 packets, and the target interface must be a
Layer 2 interface.
• Redirecting traffic to the next hop: redirects packets that require processing by an interface to the
interface. This action only applies to Layer 3 packets.
