The administration page allows the following actions:



Reboot or power off the Allegro Network Multimeter.

After clicking on the buttons, a confirmation dialogue will appear. Most of the time, rebooting is not necessary since it takes a significant time. If packet processing needs to be restarted because some options cannot be changed during runtime, the next option is a better choice since it minimizes downtime.


Restart the Allegro Network Multimeter processing software. This will reset all measured statistics.

Choosing this option will stop packet processing but the machine and its web interface is still available as the device itself is not rebooted. The packet processing core is restarted with the current settings and will begin processing packets after a few seconds.


By clicking on the Reset System Configuration button a dialog is displayed that allows to reset all settings, including the network configuration, to factory defaults and the system will be restarted. As of version 3.4 the dialog allows to keep certain settings (management interface settings, users and passwords, disk and packet ring buffer cluster settings) while setting the rest of the system configuration to defaults.

The Export System Configuration button allows you to export the entire configuration of the *Allegro Network Multimeter*. A zip compressed file can be downloaded and used for import.

The Import System Configuration button allows you to select several configuration items:

  • All settings: All settings of global settings, module settings, incident settings, user defined names, virtual link groups, Ingress (NIC) filter and IP groups, excluding management interface settings, multi-device settings, and user settings. It is possible to import these settings to all configured remote devices.
  • Management interface settings: All settings of the management interface (e.g. Wi-Fi, LAN, hostname).
  • Multi device settings: All settings on the configured remote devices.
  • Users: All users and their passwords. The admin user cannot be changed and cannot be deleted by a configuration import.

The button Save current system configuration on Multimeter will store the current configuration as a file on the device itself (in contrast to the export feature, which will download the file the user's computer).

When there are saved configuration available, any of them can be selected and load onto the system again. It is also possible to delete the configuration.

SSL certificate

The appliance comes with a pre-installed generic SSL certificate but an own certificate can be installed: The Install SSL certificate button will open a dialogue that will allow you to upload a X.509 certificate file and a RSA key file. Upon successful upload, this certificate will be used to serve the user interface. The Reset to default SSL certificate button will remove any user-provided SSL certificate and the user interface will be served using the default SSL certificate. It is currently not possible to issue a signing request procedure. To use a certificate which needs to be signed by a company CA, the user has to create that certificate on a separate machine, create the signing request, and deploy the final certificate to the appliance using the above option.

Some features also connect to external SSL services, for instance when sending email notifications via SMTP or when searching for firmware updates. Usually these SSL connections are verified with the builtin CA certificate pool. It is also possible to upload one or many own CA certificates which are used additionally to the system ones.

The button "Install SSL CA certificates" opens a dialog where the file can be selected and uploaded. This file must contain certificates in the PEM format. It may contain multiple certificates. Uploading new certificates will replace the existing ones. The button "Remove SSL CA certificates" will delete the previously installed custom CA certificates so that only the system CA pool is used again for certificate verification.
