Failed to create New port Group on ESXi 7.0 - "A Specific Parameter was not correct"

[88Kahi]

Wondering if anyone experienced same or whats workaround for this? 

I have two machines running ESXi 7.0 Update 1 Lenovo Customized Image.

On one of them I cant add new port group, neither from ESXi nor from vCenter, gives me an error all the time no mater what name or vlan I define. 

I have administrator rights and also tried to create another admin user and assign admin right to it but same. 

Also, I cant changed any parameter of Default TCP/IP stack either on same machine which refuses adding port group. 

On second machine I have no problem at all.

Any ideas?

Hi,

There are vmware kb that explain how to create it in comman line, as a troubleshouting test you can see if it lets you create it in this mode.

Configure VSS or VDS:

Configure VLAN ID:

@Alex_Romeo  Thanks for that! 

Actually I found what was causing it, I had another vSwitch created beside default one, which was causing this issue. I have deleted it as I had no use for it and it was just for testing and everything works as expected now.

I built a vSAN cluster with 5 ESXi hosts, with 2 standard vSwitch0 & vSwitch1, I mainly use vSwitch0 for production vms, and vSwitch1 just for Dell iDRAC passthrough network connectivity. 

So I am facing exactly the same issue. I am able to create a virtualmachine portgroup on first ESXi host, but not the rest of 4 ESXi hosts from my vCenter UI. it report error "A Specific Parameter was not correct". 

you mentioned another vswich, but I don't understand what to do with another vSwitch?

resolved it. it was due to the vswitch1 had a broken uplink adapter. fixed it, and I am able to add portgroup to vswitch0 now.
