configure forwarding ipmc local-network-range

configure forwarding ipmc local-network-range [fast-path | slow-path]

Description

Sets how forwarding of packets to local network IP multicast addresses (224.0.0.x) is handled.

Syntax Description

fast-path

Specifies fast-path forwarding.

Fast-path forwarding dictates that packets traversing the switch do not require processing by the CPU. Fast path packets are forwarded entirely by ASICs and are sent at wire speed rate. This consumes additional system ACL per-port or per-VLAN, depending on configure igmp snooping filters [per-port | per-vlan] selections.

slow-path Specifies slow-path forwarding (default). Packets are processed by the CPU.

Default

Slow-path forwarding is the default configuration.

Example

The following example sets up fast-path forwarding for local network IP multicast addresses:

configure forwarding ipmc local-network-range fast-path
