Configuration Files
Because some commands depend on other commands for successful execution, the XP scratchpad
simplifies system configuration by allowing you to enter configuration commands in any order,
even when dependencies exist. When you activate the commands in the scratchpad, the XP sorts
out the dependencies and executes the command in the proper sequence.
The following figure illustrates the configuration files and the commands you can use to save your
configuration:

Figure 1. Commands to Save Configurations
The XP provides many commands for changing configuration information. Use the comment
command to deactivate and reactivate commands, and to enter comments in the active
configuration file. For example, Spanning Tree Protocol is disabled by default. If, after enabling the
Spanning Tree Protocol on the XP, you want to disable STP, specify the comment out command
with the line number in the active configuration that contains the stp enable command. To
reactivate STP, specify the comment in command.
Note: If a user creates a configuration file on a new version of firmware (e.g., E9.0.7.5), the
configuration may not be 100% compatible with older firmware versions (e.g., E9.0.7.4),
resulting in configuration errors.
To enter comments in the configuration file, specify the comment line command with the line
number and the actual comments. To display the comments in the active configuration file, specify
