Using a LAN Protocol Analyzer: Guidelines

Refer to the following guidelines when you use a LAN protocol analyzer:

• If Netboot is failing, connect the analyzer to the BOOTP server interface to

determine whether it is receiving and responding to Netboot and TFTP

requests.

To read the ASCII translation, view the BOOTP reply packets for the

configuration file pathname in hexadecimal mode.

• If the BOOTP server is not receiving the requests, make sure the upstream

router is receiving and forwarding them. If it is, make sure each router

interface between the upstream router and the BOOTP server is receiving and

forwarding them.

If the BOOTP server is receiving requests, but failing to respond, refer to

“Router Fails to Netboot” earlier in this appendix.

Resolving Connectivity Problems

This section describes how to

• Display the ASN’s parameter settings.

• Change the ASN’s parameter settings.

• Debug the BOOTP server.

• Verify the BOOTP server’s setup.

• Display the IP routes.

• Display the number of BOOTP packets forwarded and dropped.

If you want to configure the ASN’s startup interface, refer to Installing and

Maintaining ASN Routers and BNX Platforms.

Note:

The LAN protocol analyzer does not decode all of the vendor tag fields.
