Configuring the

Access Point to

Send ARP

Requests

ARP requests are multicast frames, which means they are sent to all
devices on the Ethernet network. You can configure the access point to
periodically send an unsolicited ARP request to the IP router so that all
routers can update their routing tables. This ARP request lets a network
management program learn about the access point on the network by
querying routers. The auto ARP minutes parameter controls the time
interval between ARP requests.

If the address of the IP router is 0.0.0.0, then 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 Main Menu, select TCP/IP Settings. The TCP/IP Settings

screen appears.

2. In the Auto ARP Minutes field enter a time a period from 1 to 120

minutes. To disable this parameter, set the time period to 0.

3. Select Submit Changes to save your changes. To activate your

changes, select Save/Discard Changes from the menu bar then Save
Changes and Reboot
. For help, see Saving Configuration Changes
