DHCP Server
Configuration
(Data and Mgmt)
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 an individual
device IP address on Remotes in the network, but it requires some plan-
ning of the IP address range. One drawback to network-wide automatic
IP address assignments is that SNMP services might become inacces-
sible as they are dependent on fixed IP addresses.
You can make a network of radios with the DHCP-provided IP address
enabled or with DHCP services disabled. In this way, you can accom-
modate locations for which a fixed IP address is desired.
NOTE:
There should be only one active DHCP server in a network. If
more than one DHCP server exists, network devices might
randomly get their IP address from different servers every time
they request one.
NOTE:
Combining DHCP and IEEE 802.1x device authentication
might result in a non-working radio if the DHCP server is
located at a Remote radio. If possible, place the DHCP server
at the AP location.
A DHCP server can be run at a Remote, but it is not recom-
mended if 802.1x Device Authentication is in use and if the AP
gets its IP address from the DHCP server on the Remote. In
this case, the Remote cannot authenticate to allow the AP to
get its address, because the AP needs an address to do perform
802.1x device authentication. This results in an unsolvable
condition where the AP needs to get an IP address from DHCP
at the Remote, but it can’t get the address until it is authenti-
cated.
