Cannot switch ethernet port back to vntag mode Cisco UCS 6300 ver 4.1

[yak-dva86]

Hello, Cisco Community.
I studied working with UCS 6300 in gui. 
Initially, I had an ethernet port configured in vntag mode. A c240 server was connected to this port.
As part of an experiment, I reconfigured the port in Apliance. I lost connection with the server.
Then I decided to return the port to the Server role. However, the port is now in trunk mode.
How to switch it back to vntag mode int UCS GUI?

Correct configuration that i need:
interface Ethernet1/29
description S: Server
switchport vntag max-vifs 128
no pinning server sticky
switchport mode vntag
no shutdown

Configuration that i have:
interface Ethernet1/30
description S: Server
no pinning server sticky
switchport mode trunk
switchport trunk native vlan ****
switchport trunk allowed vlan ****,****-****
no shutdown

Looks like port 1/30 is waiting to discover a server/VIC on (internal) VLAN 4044.

May need to re-acknowledge the server, if re-ack doesn't work, then may need to factory default the server.

Once the server/VIC is discovered, then the port will be reconfigured for vntag.

Yes. Recover server button helps. Thanks a lot.
