SOLVED The network is already in use by another NIC

[hafedh]

Hello everyone,

I have an HyperV server with FreeNAS virtual machine installed on it.
I'm doing a test envirenment with this virtual machine.
I have One virtual NIC (172.19.11.120) for web administration
I have added two other virtual network car for configuring LACP, it's OK but when i try to configure a static IP Address i have the following error message:

• The network 172.19.11.0/24 is already in use by another NIC

Can you explain me the root cause of this issue ?

Thanks
Hafedh

Configure your LACP from the console menu, because you shouldn't have 2 NICs on the same subnet, and that's what it thinks you are doing

Thanks for your reply,

Effectively, i have all the nic in the same subnet, can you give a link describing this point and the best practices.

Best regards,
Hafedh
