HP Cache Server Appliance Administrator Guide

Chapter 2 Getting Started

Starting Traffic Line

Traffic Line is a text-based interface that can be accessed through a Telnet session. You can use Traffic Line

to perform many of the tasks you can perform in Traffic Manager. For ease of use, it is recommended that

Traffic Manager be used unless a function only available in Traffic Line is required.

Traffic Line has two command-line modes:

• TrafficLinebatchmode

You can use the batch mode to execute individual commands or to script multiple commands in a shell.

Refer to Appendix C‚ Traffic Line Commands for a list of commands.

• TrafficLineinteractivemode

You can use interactive mode to retrieve statistics and to configure Traffic Server. Traffic Line interactive

mode consists of several levels of commands. The Traffic Line interactive levels consist of the same

commands available on Traffic Manager Monitor and Configure tabs.

To start a Traffic Line session:

1. Telnet into the HP web cache appliance and select Shell Access as described in Overview of Access

Methods‚ on page 7.

You are now ready to enter Traffic Line commands.

Traffic Line commands take the following form:

traffic_line -flag argument

2. For a list of traffic_line commands, enter:

traffic_line -h

3. To enter Traffic Line interactive mode, enter the following command:

traffic_line -i

For information about monitoring Traffic Server using Traffic Line interactive mode, refer to Viewing

Statistics from Traffic Line‚ on page 68.

For information about configuring Traffic Server using Traffic Line interactive mode, refer to Configuring

Traffic Server using Traffic Line‚ on page 76.
