List of Supported Transceiver Modules
Allegro Packets allows you to use third-party vendor modules in its appliances but guarantees only warranty and support for transceiver modules sold by Allegro Packets. Any malfunction or configuration issue with third-party modules are NOT covered by the warranty.
Allegro Packets does not restrict the use of third-party SFP+ modules for the devices. However, some hardware limitations apply which are described as follows:
Built-in ports vs. expansion cards
The Allegro Network Multimeter 1000/1200/3000/3200 series have two on-board SFP+ ports which are restricted to original or branded Intel modules.
All non built-in ports are not vendor locked and can accept all transceiver modules. However, there are modules that do not work because of specific vendor extensions within the modules. This applies for all ports of the Allegro Network Multimeter x300 and x500 series and all expansion cards for the Allegro Network Multimeter 1000/1200/3000/3200.
The following table shows which kind of modules are supported by Allegro by port type:
|Port type||original or branded Intel modules||non-Intel branded modules|
|built-in SFP+ ports||x||-|
The use of Intel branded modules is mandatory for the built-in SFP+ ports. These restrictions do not apply to the additional network expansion cards (2 port and 4 port SFP+, high precision GPS card, etc.) that are available for the Allegro Network Multimeter 1000 and 3000 series. These ports accept generic modules from a wide range of vendors.
Since auto-negotiation is often not available on 1G/10G SFP+ interfaces, it may be necessary to manually set the correct speed in the `Interface Stats` section of the user interface.
QSFP+ breakout cables are NOT supported.

Link status issues with different network equipment
There is a known incompatibility with our 1G/10G SFP+ fiber modules when used with some Cisco equipment, such as a Cisco Nexus or Catalyst switch with 1G connectivity.
The solution is as follows:
- Disable auto-negotiation for the Cisco switch port which is connected to the Allegro device.
- Manually set speed to 1G for the Cisco switch port
Example configuration for Nexus:
configure terminal interface ethernet x/yy speed 1000 no negotiate auto
Actual commands depends on the Cisco model. Alternative commands are:
speed nonegotiates set port speed 1000
Combinations known to work for 1G connectivity:
- Our 1G/10G SFP+ SR module in an Allegro SFP port (article number 700)
- Cisco GLC-SX-MMD in a Cisco switch
- Cisco switch settings applied as described above
