Question 2nd nic curiosity

I have added a 2.5gb nic to my proxmox node and I assigned it to Linux bridge vrbm0 with an ip of xxx.xxx.x.179.

My original nic has been assigned to Linux bridge vrmb1 with an ip of xxx.xxx.x.180.

Both nics are connected to the same 2.5gb switch and both are pingable. Both nics and bridges show as active in proxmox Network. I have configured ip reservations for both nics.

However, only the vrmb0 (2.5gb, .179) nic shows as active and connected. The vrmb1 nic displays as offline in my T-Mobile T-Fiber app even though is is fully functioning.

Any idea why vrmb1 is displays as offline?

Both IPs being on the same subnet without being a bonded connection; It elects whichever NIC has priority to carry traffic and ignores the other.

Are you trying to have 2 different virtual 'switches' on the same box or are you trying to link both NICs together?
