Controller Based WLANs

How does the "firewall voip-proxy-arp" command work?

Product and Software: This article applies to all Aruba controllers and ArubaOS 3.0 and later. 

To decrease the amount of broadcast traffic and improve the overall throughput, enable the firewall function of voip-proxy-arp. 

The major broadcast traffic in the wireless network is ARP traffic. When voip-proxy-arp is enabled, the controller converts the broadcast ARP request packet received from the wireless client into unicast if the queried destination IP address is in the controller user table. This greatly decreases the amount of broadcast traffic in the air and improves the overall performance of the wireless network. 

(config)#firewall voip-proxy-arp 

This command is a local command and it needs to be enabled on each controller.
