Chapter 7 Command Line Interface

The command line interface (CLI) is an alternative to the GUI for managing the appliance. A script called pnic is used to perform the same management functions as the GUI.

Invoke the pnic script using the command syntax pnic command; the OS environment variables are set such that this command can be executed from any path.

CLI Commands

CLI commands are given in Command Line Reference on page 79.

The MAC rewrite feature allows the least significant byte (LSB) of a packet’s destination MAC address to be overwritten with a user-specifed value. This feature may be used to load balance or redirect traffic.
