Configuring a BOOTP Server

The Bootstrap Protocol (BOOTP) automatically assigns an IP address by adding the MAC and IP
addresses of the interface to the BOOTP server configuration file. When the switch boots, it
automatically retrieves the IP address from the BOOTP server.
The switch performs a BOOTP request only if the current IP address is set to 0.0.0.0. (This address is
the default address for a new switch or a switch that has had its startup-config file cleared using the erase
command.)
To allow your switch to retrieve its IP address from a BOOTP server, you must first determine the MAC
address of the switch and add that MAC address to the BOOTP configuration file on the BOOTP server.
To create a BOOTP server configuration file, follow these steps:
Install the BOOTP server code on the workstation, if it is not already installed.
Step 1
Determine the MAC address from the label on the chassis.
Step 2
Add an entry in the BOOTP configuration file (usually /usr/etc/bootptab) for each switch. Press Return
Step 3
after each entry to create a blank line between each entry. See the example BOOTP configuration file
that follows in Step 4.
Step 4 Enter the reload command to reboot and automatically request the IP address from the BOOTP server.
This example BOOTP configuration file shows the added entry:
# /etc/bootptab: database for bootp server (/etc/bootpd)
#
# Blank lines and lines beginning with '#' are ignored.
