I have configured my esxi host vSwitch1 to use the secondary NIC on my VMware host.

On vSwitch1 configuration I have set the VLAN to 4095 which specifies to allow all VLANs.

If my cisco switch port configuration is set to an access port my server can ping the vlan interface on the switch.

If my cisco switch port configuration is set to a trunk, whilst it stays UP UP and CDP information is available, I lose my ping from VMware VM server to the local vlan interface on the switch and I lose any server connectivity to my network.

• Switch NIC teaming policy to Route based on originating virtual port ID

• Configuration based on: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006628

  description Host Port
  switchport trunk encapsulation dot1q
  switchport trunk allowed vlan 18,220
  switchport mode trunk
  switchport nonegotiate
  spanning-tree portfast trunk
  end
  
  

Output from ESXI CLI esxcfg-vswitch -l:

~ # esxcfg-vswitch -l

Any tips welcome!!!
