DHCP servers
You can enable DHCP on your IX14 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.
