Problem with Netgear GSM7224R

[JoseM]

Hello,

My name is Jose from Spain, and i have begun in the phorum this morning.
I wish you can help me and i wish i can help us we i know something, but i am begginer with this kind of equipment.

I am working with a Switch (Netgear GSM7224R) to develop a communications network and i have a problem.

In the network we have a Laser detection device with MAC address 00:00:00:00:00:00 and sends its data (UDP) to a broadcast address 192.168.3.255The switch drops all the packets. We tried to send data to the same broadcast address from a PC (with legal MAC address) and then switch forwarded the packets. So we suspect that MAC address causes a problem.

Can you please suggest us what can be done? Is it possible to configure the switch somehow to enable the communication?

Thanks in advance for your help.

Regards

[JoseM]

Hola,

Prueba a cambiar esa MAC por otra más normal.

Si no se puede cambiar esa MAC, mira de darla de alta en el switch a ver si se puede bien sola o bien por una IP fija.

Supongo que se podría intercalar "algo" que cambie esa MAC por otra normal. Puede que un simple router sencillo sirva, incluso en modo repetidor.

Saludos.

Jose,
I don't accept that the switch is the problem.
Is it handling normal internet traffic.?
Do other switches, even un-managed work?

I am not happy about an all zero MAC address.
The first 6 digits are the manufacturer's stamp, and the 2nd 6
are "burnt in" and unique to the device itself.
The switch has to learn the MAC address of the connected
devices, and add to its MAC address table.
In my view the Laser has an incomplete MAC address.
