Multi-CPU packet distribution commands

forwarding policy

Use forwarding policy to specify a multi-CPU packet distribution policy.

Use undo forwarding policy to restore the default.

Syntax

forwarding policy { per-flow [ mode { destination-ip | destination-port | source-ip | source-port } | three-tuple ] | per-packet }

undo forwarding policy

Default

The device uses the flow-based policy.

Views

Predefined user roles

Parameters

per-flow: Specifies the flow-based forwarding. The device distributes packets of the same flow to one CPU or multiple CPUs. The CPU processes flow packets by following the first-in first-out rule.

mode: Specifies a flow-based forwarding mode.

destination-ip: Identifies a flow by destination IP address.

destination-port: Identifies a flow by destination port.

source-ip: Identifies a flow by source IP address.

source-port: Identifies a flow by source port.

three-tuple: Identifies a data flow by the three-tuple (source IP address, destination IP address, and protocol number).

per-packet: Specifies the packet-based forwarding. The device forwards packets in sequence to different CPUs, even though they are the same flow. This policy does not ensure packet order.

Usage guidelines

If you do not specify any keyword for flow identification, the device identifies a flow by source IP address, destination IP address, source port number, destination port number, and protocol number.
