Note If an rommon> prompt appears, your switch requires a manual boot to recover. Refer to
the Configuration Fundamentals Configuration Guide for instructions on manually
booting from Flash memory.
Configuring the BOOTP Server
The BOOTP protocol automatically assigns an Ethernet IP address by adding the MAC and IP addresses
of the Ethernet port 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 is the default
for a new switch or a switch that has had its startup-config file cleared using the erase command.)
To allow your ATM switch router 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. The following steps provide an example of creating a BOOTP server
configuration file:
Command Purpose
Step 1
— Installs the BOOTP server code on the workstation, if it is not
already installed.
Step 2
— Determines the MAC address from the label on the chassis.
Step 3
— Adds an entry in the BOOTP configuration file (usually
/usr/etc/bootptab) for each switch. Press Return after each entry
to create a blank line between each entry. See the example
BOOTP configuration file that follows.
Step 4
Switch# reload Restarts the ATM switch router to automatically request the
IP address from the BOOTP server.
