I must ask to customer about physical ports configuration, I could answer your question tomorrow
My configuration is like following lines for each vSwitch
~ # esxcfg-vswitch -l
Switch Name Num Ports Used Ports Configured Ports MTU Uplinks
vSwitch0 128 11 128 1500 vmnic3
PortGroup Name VLAN ID Used Ports Uplinks
VM Network 504 8 vmnic3
Management Network 504 1 vmnic3
Switch Name Num Ports Used Ports Configured Ports MTU Uplinks
vSwitch1 128 4 128 1500 vmnic1
PortGroup Name VLAN ID Used Ports Uplinks
vSwitch_20 20 2 vmnic1
Any more idea ? If you have more questions or idea. I could collect more information until tomorrow
Best regards and thanks for your reply
