Learning IP Information From a DHCP Server
7-28 TCP/IP Network Characteristics
DHCP Client Operation
During initialization, the access server acts as a DHCP client to obtain IP configuration
parameters (excluding the IP address; use a BOOTP server or the DEFINE
INTERNET ADDRESS command to configure the IP address). The access server
requests the following IP configuration parameters from a DHCP server:
• Default gateway
• Domain name
• Domain Name System (DNS) servers
• Windows Internet Naming Service (WINS) servers
The following occurs when the access server acts as a DHCP client:
The access server writes the
information it learns from the
BOOTP server to NVRAM.
The access server does
not
write the
information it learns from the DHCP server to
NVRAM. This ensures that the access server
receives the most recent information from the
DHCP server.
