Hello Everyone,

I take a screen shot.
network disconnected.jpg

Sorry for naming is different from previous discriptions.
It should be modified as follows:

4 NICs (NIC 0~3) correspond to 4 Networks (Network 0~3)
Only NIC 2 is not connected to a physical switch.
Network 0 is the management interface.
I create "External Network" called VLANNetwork2 & VLANNetwork3, assign VLAN ID 2 & 3 respectively, and link both to NIC3.
However, their Link Status is "Disconnected"
Does anyone know what is wrong?

Dear Todd,

Thanks. I noticed that.
Originally, there is only sw1.
For VLAN, I add sw2 and connect NIC2 to it.
The management interface is on Network1 instead of Network2.

Note that "XenServer management interfaces cannot be assigned to a
XenServer VLAN via a trunk port."
