VLAN in VMWare not showing up under physical adapters after adding to VSwitch

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
operationsITAuthor 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?

Is this Standard Switches ?

please supply screenshots

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 ?
operationsITAuthor Commented:
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?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
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
interface GigabitEthernet2/0/15
 switchport access vlan 20

Nexus sitting between Core and Hyperconverged appliance as backbone to Hyperconverged appliance running VMWare
interface Port-channel10
 description Nexus uplink
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 999
 switchport mode trunk

Can ping between hosts on the two new VMs on vlan 20 but not from the core to the VMs
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
okay, so that interface is probably not tagged as VLAN 20, it just states put that port in VLAN 20.

so there is no need to actually add VLAN 20 (number) to the portgroup...

BUT that does mean, that the entire port is in VLAN 20 ONLY.

The ports need to be a static trunk,  carrying all VLAN tags.

So your networking configuration is wrong on the physical switch.

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