DHCP servers
You can enable DHCP on your TX54 device to assign IP addresses to clients, using either:
n
The DHCP server for the device's local network, which assigns IP addresses to clients on the
device's local network. Addresses are assigned from a specified pool of IP addresses. For a
local network, the device uses the DHCP server that has the IP address pool in the same
IP subnet as the local network.
When a host receives an IP configuration, the configuration is valid for a particular amount of
time, known as the lease time. After this lease time expires, the configuration must be
renewed. The host renews the lease time automatically.
n
A DHCP relay server, which forwards DHCP requests from clients to a DHCP server that is
running on a separate device.
Configure a DHCP server
Note These instructions assume you are configuring the device to use its local DHCP server. For
instructions about configuring the device to use a DHCP relay server, see Configure DHCP relay .
Required configuration items
n
Enable the DHCP server.
Additional configuration items
n
The lease address pool: the range of IP addresses issued by the DHCP server to clients.
n
Lease time: The length, in minutes, of the leases issued by the DHCP server.
