    Troubleshooting Network Boot Problems Guidelines for Using Packet Capture Use the Packet Capture utility to view incoming or outgoing BootP or TFTP packets and isolate errors to a specific router interface. This utility is available through the Technician Interface on routers running BayRS Version 7.80 or later. See Using Technician Interface Software for instructions on how to use Packet Capture.

    Troubleshooting Network Boot Problems Compare the bootptab file with the sample bootptab file in Chapter 2 (see Figure 2-1 on page 2-8) and correct any inconsistency. If you cannot find an inconsistency, boot the router and view the bootpd debugger messages to determine the cause of the error. Table B-1 provides an example of the sequence of messages when a BootP exchange is successful.

    Troubleshooting Network Boot Problems Maintaining the Router Software The AN/ANH or ARN router file system resides on the flash memory card, which is not user serviceable. You use Technician Interface commands to maintain the local file system on the AN/ANH or ARN router flash memory card. For more information, see Using Technician Interface Software and Using Technician Interface Scripts.

    Configuring Remote Access for AN and Passport ARN Routers Restoring a Local File System If the AN/ANH or ARN router’s local file system becomes corrupted, you must restore it by upgrading the software image. If the router resets, reboots, or loses power while restoring or compacting its flash memory card, it automatically netboots the configuration file and software image.
