VEM Control and Packet Uplink Interfaces

Need to find out which uplink your VEM is sending control or packet information out of?  When using VPC-HM, you can use the following command to determine this information: "vemcmd show port-old" (run from the ESX CLI), or "module vem X execute vemcmd show port-old" (run from the VSM).  The updated "vemcmd show port" output only shows VM interfaces and omits the control/packet interfaces.

LTL 10 is your Control interface
LTL 12 is your Packet interface
LTL 49 and above will be your Virtual Machine Interfaces

If you look under the SG_ID column you'll see the sub group ID of each VMNIC.  From the output below, Control LTL 10 has a Pinned_SGID of 1.  LTL 18 is vmnic1 which is the member interface for SGID 1.  Likewise, Packet LTL 12 has a Pinned_SGID of 0.  LTL 17 is vmnic0, which is the member interface for SGID 0.
