DHCP client sends official IP address request to the server through the
DHCPREQUEST broadcast messages. The DHCP server sends back the
DHCPACK Unicast message to the client, and confirms the IP address that has
been allocated to the client.
The DHCP function of the PassFinder AP2520 Gateway complies with DHCP of
RFC 2131, BOOTP of RFC 951 and Bootstrap Specifications of RFC 1542. The
DHCP function provides following benefits.
z
It is easy to configure DHCP so the user can save time and cost in
configuring clients.
z
The network manager can easily manage addresses and other related
items of the lower network by managing only the central server.
To implement the DHCP server function, the following conditions shall be
satisfied.
z
When the DHCP server function is enabled, IP addresses to be allocated to
the server shall be separated from the addresses that will not use the DHCP
function. (For example, servers and printers whose addresses shall be
fixed.)
z
If necessary, the user shall define DHCP options to use in the Gateway – the
default Gateway and the DNS server.
PassFinder AP2520 supports not only DHCP Server function but also DHCP
Clients and Relay functions. If it configured DHCP in address field instead IP
Address, AP2520 operate in DHCP Client mode.
