Troubleshooting Network Boot Problems

Router Fails to Perform Directed Netboot
If the AN/ANH or ARN router 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 required files reside on the TFTP file server.
•The boot image file is krnl_an.exe for an AN/ANH or krnl_arn.exe for an
ARN.
Contact the Nortel Networks Technical Solutions Center if you cannot find and
correct the problem.
Router Netboots, but Fails to Load Applications
If the AN/ANH or ARN router netboots a kernel file successfully, but displays an
error message indicating that it cannot load specific applications, it is unable to
retrieve files from the TFTP server that were provided on the software image.
These files are required to perform functions such as running the protocols
specified in the configuration file and displaying the log.
To troubleshoot a failure to load applications, do the following:
1. Ensure that, after booting, you have at least one interface configured
through which the file server that supplied the kernel file can be reached.
This is required for a router that has obtained its software image over the
network to load application or string files.
2. Ensure that all the application and string files (files wit h .exe and .str
file-name extensions) reside in the same directory as the kernel file.
3. Verify that you have TFTP configured on the router. To do this, display
the router’s loadmap screen message.
If tftp.exe is missing, load it on the router.
4. Use Site Manager to ensure that IP is enabled and that TFTP is
configured in the router configuration file.
