Hi Rahman
I attached two configurations of the two X440's.
Yes, The DCHP server is the firewall, recently We added to the network five DM-NVX-350 witht statics ip address.

Is the same configutation for two switch.

The log looks good. But obviously you are using more than the 5 devices.
Are you sure, you don't have any duplicate MAC-Adress in yout network? That would explain everything.

[Rahman_Duran]

Can you send config of the two X440's? With default config, they should work like dump switches and you should connect to internet.

Do you add IP addresses to PC's manually or does your firewall/router(192.168.1.1) distributes them via DHCP?

Doe it work when you directly connect the PC's to 192.168.1.1?
