The following new software features are supported by the Cisco 7000 family for Cisco IOS
Release 12.1(5)T:
AutoInstall Using DHCP for LAN Interfaces
Platforms: Cisco 7100 series, Cisco 7200 series, and Cisco 7500 series routers
The AutoInstall Using DHCP for LAN Interfaces feature replaces the use of the Bootstrap Protocol
(BOOTP) with the use of the Dynamic Host Configuration Protocol (DHCP) for Cisco IOS AutoInstall
over LAN interfaces. AutoInstall is a Cisco IOS software feature that provides for the configuration of
a new routing device automatically when the device is initialized. DHCP (defined in RFC 2131) is based
on the Bootstrap Protocol, which provides the framework for passing configuration information to hosts
on a TCP/IP network. DHCP adds the capability of automatic allocation of reusable network addresses
and additional configuration options. In Cisco IOS Release 12.1(5)T, the IP address procurement phase
of the AutoInstall process is now accomplished using DHCP for Ethernet, Token Ring, and FDDI
