Ethernet Link (H/W) Watch
(AP Only)
—Detects the lack of an Ether-
net connection to the LAN port at the electrical level (link integ-
rity). The current AP will broadcast a beacon signal indicating
its “NOT AVAILABLE” status so Remotes that hear it do not
try to associate to it. Once the Ethernet connection is restored,
this beacon signal changes to “AVAILABLE” and Remotes are
allowed to join in. [

Ethernet Link Poll Address
(AP Only)
—When an IP address is pro-
vided, the Access Point pings the remote IP device every 60 sec-
onds to test the integrity of the backhaul link. If this link is not
available, the AP will advertise its “NOT AVAILABLE” status
in the beacon signal so Remotes do not try to associate to it.
Once the IP address is reachable, this beacon signal changes to
“AVAILABLE” and Remotes are allowed to join in. 0.0.0.0 dis-
ables this function. Any other valid IP address enables it.

2.4.4 DHCP Server Configuration
A transceiver can provide automatic IP address assignments to other IP
devices in the network by providing DHCP (Dynamic Host Configura-
tion Protocol) services. This service eliminates setting individual device
IP address on Remotes in the network, but it still requires thoughtful
planning of the IP address range. One drawback to network-wide auto-
matic IP address assignments is that SNMP services may become inac-
cessible as they are dependent on fixed IP addresses.
The network can be comprised of radios with the DHCP-provided IP
address enabled or with DHCP services disabled. In this way, you can
accommodate locations for which a fixed IP address if desired.
