2. Hardware Deployment

2.1. Management Access

Step 1: Connect power supply

Allegro 1000/3000 (portable version):

Allegro 1200/3200 (rack version):

Step2: Connect management LAN connection to the port labelled as "MGMT" (the bottom left port):


Allegro 200 (portable version):

Connect management LAN connection to the USB-Ethernet adapter and insert into any USB post:

By default, the device will query an IP address via DHCP dynamically from your network.

Alternative: Insert WiFi Adapter to any of the two USB ports:

By default, the device will open an access point so other smartphones, tablets, or laptops can connect to the access point and access the web interface.

During initial install, your network connected to the MGMT port assigns an IP address to the Network Multimeter via DHCP. Later in the web configuration section, it is possible to configure a fixed IP or enable a DHCP server running on that network interface. Also, the wireless device can be enabled to access the web interface as a WiFi client or access point.

If access is not possible with the default configuration, a temporary IP address can be assigned: After booting, connnect an USB keyboard to any of the USB ports and press "Shift+S". Now the IP address is assigned to the LAN interface and it is valid until power off. If this is already taken another address in the range from to will be used. You can check the current IP address on a connected monitor.

2.2. Network Measurement Installation

The Allegro Network Multimeter analyzes all traffic going through any of network interfaces. It can be deployed in the following setups:

1. Bridge Mode

Every pair of interfaces build a layer-2 bridge, sending all incoming traffic to the corresponding interface. Each vertival pair of interfaces forms a bridge.

The interface number 1 only processes incoming traffic from a mirror port.


Both interfaces build a layer-2 bridge, sending all incoming traffic to the corresponding interface:

2. Sink mode

Received packets will be processed, but not forwarded. Connect the network multimeter to a hardware tap by connecting both tap ports to the device. Alternatively, a switch or router mirror port can be connected to any of the device network interfaces:

Default behavior is the bridge mode, thus running as an in-line device. The link mode can be configured via web interface (menu „Settings → Global settings“):

3. Device Start

1. Press the power button at the front of the device. The device will boot within two minutes.

2. LAN access: The device got its IP from the DHCP server in your network. Check the console output on an attached monitor or ask the server administrator for the IP of the device, then enter the IP into the URL bar of your web browser.

3. WiFi access: 

  • - SSID: allegro-mm-xxxx (the last characters depend on hardware parameters of the individual device)
  • - WPA2 password: Allegro-MM
  • - Enter http://allegro/ or into the URL bar of your web browser.

4. Web interface authentication:

  • - User name: admin
  • - Password: allegro

4. Management Interface Configuration

You can configure the management interfaces by accessing the web interface at „Settings → Management interface settings“. The available options are described in the online manual which can be accessed in the web interface.

5. IP KVM Interface (Allegro 1000/3000 only)

The device supports a dedicated IPMI based device management which can be accessed by connecting the „IP KVM“ port to your network. The vendor of the interface is SuperMicro, so please refer to the IPMI manual available at the homepage:

6. Configutarion Reset and Automatic Firmware Update

The Configuration Reset can be used to remove all user-made settings and restore the configuration to the factory settings.

1. Using the web interface: Go to menu Settings → Administration and click on "Reset system configuration". All settings including the network configuration will be reset to factory default.

2. Using the boot menu: This method can be used if access is no longer possible (maybe due to misconfiguration). Follow the instruction in the next section and select "Configuration reset" from the menu.

3. Using a keyboard: The Configuration reset is also possible with an attached keyboard. This method will also search for a new firmware version and install it automatically. This option may be selected if the device should use the latest firmware and default settings (for example, when the device is sent to a different user). To do so, attach a keyboard to an USB port and press "Shift+R". After the successful reset and update the Multimeter will turn off. Otherwise, it will still stay powered on. Attach a monitor to check error messages.

7. Firmware Update Notification

Update information via email

With each release, Allegro Packets will send you an email with release notes and a link to download the update. If you want to be added to this mailing list, please send us an email with your serial number to with the subject „Release“. You will find the serial number via the web interface under Info → System Info → System ID. A link to unsubscribe from the mailing list is included in every email.

On the website

All information about updates are summarized for you on our website under Our product → Support.

Using the Allegro web interface

Start your Allegro and click Settings on the left side of the menu and then „Firmware updates“. Click on "Check for new firmware" and the Allegro will tell you if a new version is available for download. If so you can choose to download it directly to the device. In addition, this page provides an overview of all versions available to you. To start the new version, click on „Activate“.

8. Factory Reset

To reset the device configuration back to factory settings, follow these instructions one by one. The factory reset will clear the whole system installation and restores the firmware version to the version which was originally shipped with the Multimeter. You may want to update to the current firmware afterwards (see the Firmware update section).

9. Additional Notes

Allegro 200 may get warm: The Allegro Network Multimeter is a passively cooled high-performance device. Depending on environment, the device may get warm. Enclosure temperatures up to 40 – 50 C are considered normal. The device is certified up to 104 C. Place the device on a heat conductive surface or make sure at least one side is not covered to provide enough air flow.

Manual: The device manual can be accessed from the web interface. Each web section contains a button to access context specific documentation, the complete manual can be opened by clicking on the manual link in the menu.
