Mediatrix 4100
Automatic Configuration Update
You can configure the Mediatrix 4100 to automatically update its configuration. This update can be done:
 Every time the Mediatrix 4100 restarts.
 At a specific time interval you can define.
Automatic Update on Restart
The Mediatrix 4100 may download new configuration files each time it restarts.
 To set the automatic update every time the Mediatrix 4100 restarts:
1. Set the configuration file server host and port as defined in “
Configuration File Server Settings” on
page 99.
2. Place the configuration files to download on the computer hosting the HTTP or TFTP server.
These files must be in a directory under the root path.
3. If not already done, set the configuration file path as described in “
Setting up the Configuration File
Download” on page 101.
4. In the configFileFetchingMIB, set the configFileTransferProtocol variable to either http or tftp.
If you are using the HTTP protocol to download the configuration, be aware that your HTTP server
may activate some caching mechanism for the file download. This mechanism caches the initial file
download for later processing, thus preventing changes or update of the original file by the user.
This can cause strange problems if a user wants to edit a configuration file to modify values and
upload it immediately. The result will still return the original file and not the new one.
5. If you are using the HTTP protocol to download the configuration and your HTTP server requires
authentication, set the following:
• The user name in the configFileTransferUsername variable.
• The password in the configFileTransferPassword variable.
The Mediatrix 4100 supports basic and digest HTTP authentication, as described in RFC 2617.
6. Set the configFileAutoUpdateOnRestartEnable variable to enable (in the
configFileAutomaticUpdate group).
7. In the sysConfigMIB, set the sysConfigDownloadConfigFile variable to
automaticInitiateFileDownload.
The automatic configuration update will be performed each time the Mediatrix 4100 restarts.
The unit configuration is only updated if at least one parameter value defined in the downloaded
configuration files is different from the actual unit configuration.
Caution: When downloading via HTTP, the configuration file server’s port must be 80. You can query the
actual port assigned in the imagePrimaryPort and imageSecondaryPort read-only variables (in the
ipAddressStatus folder).
If you are using a DHCP server and it did not provide the proper port, reconfigure it with the proper port or
use a static configuration. See “Configuration File Server Settings” on page 99 for more details.
