Configuring the
Access Point to
Send ARP
Requests
ARP requests are multicast packets, which means they are sent to all
devices on the network. The access point periodically sends an
unsolicited ARP request to the default IP router so that all routers can
update their routing tables. This ARP request enables a network
management program to learn about the access point on the network
by querying routers. The auto ARP period controls the time interval
between ARP broadcasts.
If the address of the default IP router is 0.0.0.0, the access point sends an
ARP request to its own IP address. Without this option, an access point
might not use its IP address for extended periods of time and the IP
address would expire from the router ARP table. If the IP address expires,
the network management program must ping all potential addresses on
a subnet to locate active IP addresses or require the user to enter a list.
You should not let the IP address for the access point expire.
To set the auto ARP period:
1. From the menu, click TCP/IP Settings. The TCP/IP Settings screen
appears, as shown in Figure 22.

2. In the Auto ARP Minutes field enter a time period from 1 to 120
minutes. To disable this parameter, set the time period to 0.
