Troubleshooting Network Boot Problems
114084 Rev. A A-5
4.
Make sure that the tftp dgram entry in the /etc/inetd.conf file is correct
for your system.
Refer to “Setting Up a TFTP Server” in Chapter 3.
5. Refer to “Verifying the BOOTP Server Setup” later in this appendix.
Router Fails to Perform Directed Netboot
If the AN/ANH/ARN fails to perform Directed Netboot, verify the following:
The interface that connects the router to the TFTP file server is configured
with an IP address.
All necessary files are, in fact, residing on the TFTP file server.
The boot file is krnl_an.exe for an AN/ANH or krnl_arn.exe for an ARN.
Contact your local Bay Networks Technical Response Center if you perform the
instructions in these sections but still cannot find and correct the problem.
Router Netboots, but Fails to Load Applications
If the router Netboots a software image successfully, but displays an error
message indicating that it cannot load specific applications, it is failing to retrieve
files from the TFTP server that provided the software image. These files are
necessary to perform functions such as running the protocols specified in the
configuration file or displaying the log.
Do the following:
1. Make sure that, after booting, you have at least one interface configured
through which the file server that supplied the kernel image can be
reached.
This is necessary for a router that has obtained its image over the network to
load application or string files.
2. Make sure that all the application and string files (files with .exe and .str
filename extensions) reside in the same directory as the kernel image.
3. Verify that you have TFTP on the router. To determine this, display the
router’s
loadmap screen message.
If tftp.exe is missing, load it onto the router.
