About DHCP
You can use DHCP to perform the following actions on a single or multiple Console
Server (the ‘unit(s)’)s on its/their boot-up:
auto-configure with minimal information; e.g. only an ip address
auto-configure with basic setup information (ip address, subnet mask, broadcast
address, etc.)
download a new version of software
download a full configuration profile (saved from another unit)
DHCP is particularly useful for multiple installations: you can do all the unit’s
configuration in one DHCP file, rather than configure each unit manually.
Another advantage of DHCP is that you can connect a unit to the network, turn on its
power and let auto-configuration take place. All the configuration is carried out for you
during the DHCP process.
The the unit’s implementation of DHCP is compatible with RFC 951.
On bootup or power-up, the unit will send a broadcast request to the DHCP server(s) on
the network. The request contains the ethernet address of the unit; it asks for network
configuration details (internet address, subnet mask, etc.). This process is shown in
DHCP request and response on page 35 .
You can stop the DHCP server from replying to the unit; see Appendix F BOOTP
