TCP/IP Network Characteristics
Learning IP Information From a DHCP Server
Description
You can use the Dynamic Host Configuration Protocol (DHCP) to automatically
configure TCP/IP characteristics on the access server and remote clients. DHCP
provides dynamic assignment of IP addresses and discovery of IP configuration
parameters (for example, subnet mask or default gateways). A DHCP client
requests and receives this information from a DHCP server on the network.
Enabling DHCP on the access server allows it to learn some of its IP configuration
information from a DHCP server. The access server does not receive its IP address
from the DHCP server; you must manually configure it or use a BOOTP server.
Enabling DHCP on the access server also allows remote dial-up clients to receive
dynamically assigned IP addresses and IP configuration parameters from the
DHCP server. Depending on the situation, the access server acts as a DHCP client
or proxy.
By default, the DHCP setting on the access server is ENABLED. If you do not
have a DHCP server on your network, disable DHCP. (See the Enabling and
Disabling DHCP section in this chapter.)
