Question

VMs not accessible when attached 2 vNICs with two different VLANs

Hello, 
We have two Nutanix box each one has a node, both of them are connected to one physical switch.

The Scenario is: We have one VM with Windows Server 2019 that has a File Server solution that needs to be accessible for two different VLANs (10.9.61.xx && 10.9.64.xx)

The Steps that we did.
1- Created one virtual switch "vs0" with Active-Back
2- Created 3 VLANs on the same switch "Vlan0, VLAN 61, and VLAN 64".
3- Attached 2 vNICs with VLAN 61 and 64 to that VM.

The issue is: that we are unable to access the server from the "user device that is part of VLAN61 or 64".  but accessible from VLAN 0 if attached to the VLAN 0.

Hello,

Hope you’re well.

Can you confirm the switch configuration for the physical ports towards the Nutanix hardware?

I think the problem here may be that the switchports are not trunk ports with the allowed vlans - 61, & 64.

A ‘sh run’ or equivalent from the Switch would be good to start with.

Thanks,

Kim

configure trunk port on the switch

configure trunk port on the switch 

and you verified the nic settings to just make sure they are assigned to the correct vlans?
