Load/Save

With this dialog you can:

Loading a Configuration

In the “Load” frame, you have the option to

If you change the current configuration (for example, by switching a port off), the graphical user interface changes the “load/save” symbol in the navigation tree from a disk symbol to a yellow triangle. After saving the configuration, the graphical user interface displays the “load/save” symbol as a disk again.

Loading configuration of the offline configurator

Installing and starting the offline configurator

To create a configuration file in the offline configurator, proceed as follows:

Creating an XML configuration file with the offline configurator

Note: The offline configurator interface contains only dialogs, tables and input fields for parameters writable to the device. You cannot read parameters from the device in the offline mode. The range of the offline configurator interface is reduced vis-à-vis that of the graphical user interface.

You can find a description of the settings you can make in the offline configurator interface in the respectively appropriate section of this manual.

The following applies to the above example: You can find a description of the parameters that can be set in the offline configurator Basic Settings:System dialog.

See System.

Loading an XML configuration file onto the device

Once the offline configuration file has loaded successfully, the device returns in the subsequent "Configuration" window an overview of the configuration parameters that have loaded. By clicking in this window you can choose between the following two views:

Tables View

In the Tables View you get an overview in tabular format of the configuration parameters that have loaded:

Application date

Point in time (date and time of day) when you loaded the offline configuration file onto the device.

Notation: yyyy-mm-dd hh-mm-ss

yyyy = valid year

mm = 1 to 12

dd = 1 to 31

hh = 0 to 23

Name of the configuration parameter (MIB variable)

Value

Value of the configuration parameter (MIB variable), which was set by loading the offline configuration file.

The device's success at loading the respective configuration parameter

  • (0) = Success

  • (1) = Response PDU Too Big

  • (2) = Variable does not exist

  • (3) = Cannot modify variable: Bad Value

  • (4) = Cannot modify object, Read Only

  • (5) = Cannot perform operation, General Error


Text View

In the Text View you get an overview in textual format of the configuration parameters (MIB variables) that have loaded:

The device lists the individual configuration parameters in the following form. The data are separated by commas:

Saving the Configuration

In the “Save” frame, you have the option to

Note: For script configuration files, note the following characteristics:
Note: The loading process started by DHCP/BOOTP (refer Network) shows the selection of “from URL & save local” in the “Load” frame. If you get an error message when saving a configuration, this could be due to an active loading process. DHCP/BOOTP only finishes a loading process when a valid configuration has been loaded. If DHCP/BOOTP does not find a valid configuration, finish the loading process by loading the local configuration from the device in the “Load” frame.

If you change the current configuration (for example, by switching a port off), the graphical user interface changes the “load/save” symbol in the navigation tree from a disk symbol to a yellow triangle. After saving the configuration, the graphical user interface displays the “load/save” symbol as a disk again.

After you have successfully saved the configuration on the device, the device sends a trap hmConfigurationSavedTrap together with the information about the AutoConfiguration Adapter (ACA), if one is connected. When you change the configuration for the first time after saving it, the device sends a trap hmConfigurationChangedTrap.

Saving configuration for the offline configurator

Configuration Signature

A configuration signature as seen in the “Configuration Signature” frame of the Basic Settings:Load/Save dialog, uniquely identifies a particular configuration. Every time you save a configuration to the device, the device generates a random sequence of numbers and/or letters as a signature for the configuration. The signature changes every time you save the configuration to the device. The device stores the randomly generated signature with the configuration to assure the device loads appropriate configuration after a reboot.

URL

The URL identifies the path to the tftp server on which the configuration file is to be stored. The URL is in the format: tftp://IP address of the tftp server/path name/file name (e.g. tftp://192.168.1.100/device/config.dat).

Note: The configuration file includes all configuration data, including the passwords for accessing the device. Therefore, pay attention to the access rights on the tftp server.

Deleting a configuration

In the "Delete" frame, you have the option to

Note: With the exception of the watchdog configuration, the device stores user defined configurations in Non-volatile Memory. The device stores the watchdog configuration separately. Therefore, when you reset the configurations to the default settings, using the “Current Configuration” or “Current Configuration from the Device” delete functions, the watchdog configuration remains in the device.

Using the AutoConfiguration Adapter (ACA)

The ACAs are devices for saving the configuration data of a device. An ACA enables the configuration data to be transferred easily by means of a substitute device of the same type.

Note: When replacing a device with DIP switches, check the DIP switch settings to ensure that they are the same.

Storing the current configuration data in the ACA:

You have the option of transferring the current device configuration, including the SNMP password, to the ACA and the flash memory by using the “to device” option in the “Save” frame .

Note: The device saves the configuration, with the exception of its SSH key (refer Telnet/Web/SSH Access ). You will find instructions on how to transfer the SSH key of the old device to the new one in the document “Basic Configuration User Manual”, chapter “Replacing defective devices”.

Loading the Configuration file from the ACA:

When you restart the device with ACA connected, the device adopts the configuration data from ACA and saves it permanently in the flash memory. If the connected ACA contains invalid data, for example, if the ACA contains an unchanged default configuration, the device loads the data from the flash memory.

Note: Before loading the configuration data from the ACA, the device compares the password in the device with the password in the ACA configuration data.

The device loads the configuration data if

Tab. ACAstatus

Status

Meaning

notPresent

No ACA present

ok

The configuration data from the ACA and the device match.

removed

The ACA was removed after booting.

notInSync

- The configuration data of the ACA and the device do not match, or only one file exists

In these cases, the ACA status is identical to the status “not in sync”, which sends “Not OK” to the signal contacts and the device status.,
,
or
- no configuration file is present on the ACA or on the device
In this case, the ACA status (“notInSync”) deviates from the status “ACA not in sync”, which sends “OK” to the signal contacts and forwards the device status.
.

outOfMemory

The local configuration data is too extensive to be stored on the ACA.

wrongMachine

The configuration data in external memory originates from a different device type and cannot be read or converted.

checksumErr

The configuration data is damaged.

Cancelling a configuration change

Operation

If the function is activated and the connection to the device is interrupted for longer than the time specified in the field “Period to undo while connection is lost [s]”, the device then loads the last configuration saved.

Note: Deactivate the function after you have successfully saved the configuration. In this way you help prevent the device from reloading the configuration after you close the web interface.
Note: When accessing the device via SSH, also note the TCP connection timeouts for the cancellation of the configuration.

Watchdog IP address

“Watchdog IP address” shows you the IP address of the PC from which you have activated the (watchdog) function. The device monitors the link to the PC with this IP address, checking for interruptions.
