ETS Installation Guide
Area to Check Explanation
The ETS is in the
loadhost’s
/etc/hosts file
The ETS must be in this file for the host to
answer a BOOTP or TFTP request.
The download file is in the
correct directory and is
world-readable
The download file must be in the correct
directory and world-readable. Specify the
complete pathname for the download file in
the BOOTP configuration file, or add a
default pathname to the download filename.
The ETS and host are in
the same IP network
Some hosts will not allow BOOTP replies
across IP networks. Either use a host
running a different operating system or put
the ETS in the same IP network as the host.
RARP Troubleshooting
Table B-5. RARP Troubleshooting
Area to Check Explanation
The ETS name and
hardware address in the
host’s /etc/ethers file
The ETS name and hardware address must
be in this file for the host to answer a RARP
request.
The ETS name and IP
address in the /etc/hosts
file
The ETS name and IP address must be in
this file for the host to answer a RARP
request.
The operating system
Many operating systems do not start a
RARP server at boot time. Check the host’s
RARPD documentation for details, or use
the ps command to see if there is a RARPD
process running.
Entering Commands at the Boot Prompt
If the Boot> prompt appears on the serial console instead of the Local> prompt, one
of two things may be wrong. Either the ETS does not have enough information to
boot, or the network or flash boot has failed. If pressing the Return key does not
display a prompt, press any other key. The Boot> prompt should appear.
If the ETS does not have enough information to boot, or the network or flash boot has
failed, it will print a message to the console and wait ten seconds for serial port
activity. If it detects no serial port activity, it will continue booting provided the flash is
good. However, if the user presses a key during that time period, the ETS will display
the Boot> prompt.
Note: If you see the message “Will attempt another download in x minutes,” press
any key for the Boot> prompt.
A series of commands called Boot Configuration Program (BCP) commands can be
entered at the Boot> prompt to configure the ETS. These commands are a subset of
the entire ETS command set. For example, a typical TCP/IP configuration might use
the following commands:
