Configuration Files
The ESP serial hub will accept a DOS or UNIX style text file containing configuration commands.
A configuration file may be loaded from a BootP or DHCP server for initial configuration. A
download may also be initiated using the web interface or the configuration utility.
A file-based reconfiguration of an ESP hub may also be initiated using a third party SNMP agent.
An SNMP MIB is available through Avocent Technical Support.
The configuration file is processed one line at a time. If an error is encountered, the line containing
the error and all remaining lines in the file will be ignored. Commands in lines that were parsed
before the errored line will be executed.
Sample Configuration File
A sample configuration file is available through the web interface. This file contains every
supported command with most of the required and optional parameters for one serial port. All lines
are preceded by a comment character (#).
To use the sample configuration file as a template:
1. Access the web interface. See Accessing the Web Interface on page 31.
2. Select Documentation from the Main Menu.
3. On the Available Documentation page, enable the Sample Configuration File radio button,
then click Apply. The sample file will be displayed.
4. Copy the sample file. You may either select and paste the content or save the frame to
your system.
5. Using an editor of your choice, remove the comment character (#) from the beginning of each
line containing a command you want to execute.
6. Following the rules listed in File Format and Command Syntax on page 56, tailor the required
and optional parameters to meet your requirements. For example, if the sample command
enables a feature and you want to disable it, replace the word enable with disable. Replace
address and port parameters with values that are meaningful to your configuration.
7. Copy and edit the commands as needed to configure all serial ports.
8. Save the customized file.
