Enabling DHCP D DHCP, or Dynamic Host Configuration Protocol, is an open industry standard that simplifies administering networks based on Transmission Control Protocol/ Internet Protocol (TCP/IP). DHCP allows network resources to go farther by enabling a unique IP address to be assigned to a specific device (HP bridge, client host, etc.) on a non-permanent, dynamic basis. DHCP makes network administration easier-the larger the network, the greater the benefit. DHCP accommodates larger networks since it can assign temporary IP addresses for a specified time interval. DHCP frees network administrators from having to configure each bridge or host manually. Other benefits of a DHCP environment include: ■ No additional address configuration is required for client hosts. ■ IP addresses can be reused or leased for specific time periods. ■ IP address assignment is better managed. For example, if the IP address for a bridge in a network changes and 250 client computers have to be updated with the new address, you do not have to manually reconfigure every workstation. Without DHCP, permanent IP address configuration is the only option. This means a network administrator is required to manually configure a permanent IP address for each individual bridge or client host. Permanent IP addresses require more network resources, but are useful when dealing with smaller LAN environments. Without dynamic address assignment, bridges and hosts have to be configured manually one by one. IP addresses must be managed to avoid duplicate use, and changes must be applied to clients by hand. Configuration information is not centralized, and it is difficult to get a view of all bridge or host configurations. The use of TCP/IP and DHCP both contribute to networking and the growth of the Internet. TCP/IP uses open protocol standards that enable the forming of wide area networks (WANS). For each HP bridge to identify itself on a TCP/IP network, it must be uniquely identified by the following information: 235

Enabling DHCP
DHCP, or Dynamic Host Configuration Protocol, is an open industry standard
that simplifies administering networks based on Transmission Control Protocol/
Internet Protocol (TCP/IP). DHCP allows network resources to go farther by
enabling a unique IP address to be assigned to a specific device (HP bridge,
client host, etc.) on a non-permanent, dynamic basis.
DHCP makes network administration easier-the larger the network, the greater
the benefit. DHCP accommodates larger networks since it can assign
temporary IP addresses for a specified time interval. DHCP frees network
administrators from having to configure each bridge or host manually.
Other benefits of a DHCP environment include:
■
No additional address configuration is required for client hosts.
■
IP addresses can be reused or leased for specific time periods.
■
IP address assignment is better managed. For example, if the IP address for
a bridge in a network changes and 250 client computers have to be
updated with the new address, you do not have to manually reconfigure
every workstation.
Without DHCP, permanent IP address configuration is the only option. This
means a network administrator is required to manually configure a permanent
IP address for each individual bridge or client host. Permanent IP addresses
require more network resources, but are useful when dealing with smaller LAN
environments. Without dynamic address assignment, bridges and hosts have
to be configured manually one by one. IP addresses must be managed to
avoid duplicate use, and changes must be applied to clients by hand.
Configuration information is not centralized, and it is difficult to get a view of
all bridge or host configurations.
The use of TCP/IP and DHCP both contribute to networking and the growth of
the Internet. TCP/IP uses open protocol standards that enable the forming of
wide area networks (WANS). For each HP bridge to identify itself on a TCP/IP
network, it must be uniquely identified by the following information:
