Troubleshooting

Overview

This appendix provides some guidance for troubleshooting the HP ProCurve

Threat Management Services (TMS) zl Module. It first provides general trou-

bleshooting information that you can use whether the TMS zl Module is

operating in routing mode or monitor mode:

■ “Basic Troubleshooting Tools” on page D-3

■ “Troubleshooting Problems with the Installation and Boot Process” on

page D-14

The remainder of the appendix is divided into two sections:

■ “Troubleshooting the TMS zl Module in Routing Mode” on page D-19

■ “Troubleshooting the TMS zl Module in Monitor Mode” on page D-107

Basic Troubleshooting Tools

Before you begin troubleshooting, you should be familiar with some basic

troubleshooting tools that the TMS zl Module provides (in either routing mode

or monitor mode):

■ ping

■ traceroute command

■ nslookup command

■ show commands

■ capture command

You can use ping from either the Web browser interface or the command line

interface (CLI). The other commands are available from the CLI.

In addition to using these tools, you may also want to obtain a third-party

protocol analyzer so that you can capture and view the packets being trans-

mitted on different interfaces on your network. You can also configure the

module’s capture command to send output to a file and then open that file in

a protocol analyzer. This allows you to analyze the capture in more depth.
