Hello,
I added a vlan to a vswitch and see it with active ports 0
Under Physical adapters all VLANs show, but not this one so what am I missing in adding the VLAN?

Does the VLAN work ?

I assume you just added a number on a virtual machine portgroup ?

Did you make any changes to the physical network configuration and trunk configuration on the physical switches ?

There is a line on vSwtich0 between the VLAN and vnics, but when you select the VNIC information under networks it shows the others except the new one I'm trying to add.  I can't recall what i'm missing

Commented:
There are 2 hosts with VMs on the new VLAN and they can ping each other.  The switch is pass-thru to a core switch that cannot ping either VM on the new VLAN but can ping all other hosts and VMs.

I did add the VLAN, but think I need to do something to the physical adapters in VCenter?

Standard

Added VLAN 20 (see attached)

To Physical Adapters (see attached)

But if you click on the "i" for physical adapter information the vlan20 doesn't show up, where all others do.  I am not in this a lot so it's been a minute and I'm kicking myself I can't find this.

no more configuration than that to do on the vSwitch (virtual machine portgroup).

but vmnic2 and vmnic3 - this is a static trunk ?

and it's configuration has been changed ?

Ok, I wasn’t seeing anything more I could do.

Not sure how VMNIC2 & 3 know of the other VLANs but must be static or I’m of the believe it would have learned of vlan20

Not sure where to change this host?

I'm afraid it's nothing to do with the host! or any configuration.

The host just receives the traffic from the trunk, the trunk must already be configured.

Can we have the configuration information from the switch.

Core Switch to Hyperconverged appliance running VMWare

Can ping between hosts on the two new VMs on vlan 20 but not from the core to the VMs

Although we had the port tagged we have two switches and didn't have the VCP port tagged.
