HI as per to this to VMware Knowledge Links Vlan ID for port group should be set to "0" for Physical Switch Configuration.

https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003806
https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004074

My doubt is that since switch port mode access is configured on the interface. How the traffic will be segregated between 2 nic adapters having different Standard Distribution Switch. Since I'm able to ping both on both adapters.

What I mean how can I control this?

Hope my question is clear.

Thanks,

a VLAN Tag of ZERO (0) is a special internal VLAN, which usually should not be used.

Could you explain what you are trying to do ?

I have 3 Subnets
10.42.5.0/24 Vlan 5 Management (Switchport Trunkport configured in physical switch allowed vlan 5,10,20)
10.43.5.0/24 Vlan 10 VM Machine Network port group
10 44.5.0/24 Vlan 20 FT logging for (Hearbeat)

Currently i configured switchport mode access on the switch to allow communication on all 3 vlans.

created 3 distribution switch and separated the subnets.

All VM's are on Production Standard Distribution Switch

But port group VLAN ID is currently set to 0 if i set it to 10 im not able to ping the subnet gateway 10.43.5.1

If you do not set any VLAN Tag on your ESXi virtual machine portgroups or switches, ethernet traffic will flow down the DEFAULT VLAN on your physical ports.

It's usual to configure physical ports with a default VLAN.

you need to use Inter VLAN Routing in your physical switches, or use a router.
