protocol arp

Address Resolution Protocol (ARP) is a network layer protocol that

automatically maps IP addresses to hardware Media Access Control (MAC)

addresses. When a network node sends data to an IP address on its

segment, it broadcasts an ARP request to resolve the IP address to an

Ethernet MAC address.

ARP protocol must be protected to be able to forward traffic, especially the

high priority flows including VoIP flows. Protecting ARP ensures ARP

resolutions to succeed so the critical flows are correctly forwarded.

When QoS is turned on, always protect ARP. See arp table

Syntax config protocol arp gq <class>

Parameters qg class Enter the quality group class.

Example The following command creates the quality group arp_protect then assigns

it.

> config qos group arp_protect qg A3 type policed committed

100000

> config protocol arp qg arp_protect

commands
