Filtering ARP frames is often used for controlling and managing network activities.

Filtering ARP frames

It is possible to match all ARP packets using the EtherType header, which is 0x0806 for ARP. For example:
flow create 0 group 0 pattern eth type is 0x0806 / end actions queue index 0 / end
This command creates a flow rule that matches frames with the EtherType, 0x0806 to deliver ARP frames to queue 0.
