Drop VM's in this Port profile and they are no connected;

port-profile type vethernet VM-10.42.252.0_24-VLAN3252-lse_prodc
  vmware port-group
  switchport mode access
  switchport access vlan 3252

Upstream ports are 3750 ports configured below:

interface GigabitEthernet4/0/28
switchport trunk encapsulation dot1q
switchport trunk native vlan 999
switchport trunk allowed vlan 600,3244,3246,3248,3250,3252,3254
switchport mode trunk
no mdix auto
spanning-tree portfast

Port channel status on the 1000v:

                                     Eth3/5(P)    Eth3/8(P)    Eth3/9(P)

Need an idea of where to go.. Already have TAC case.

Moved the VM's using the 1000v port profile over to the VSwitch for now until I can get the port profile working agin.

Hey Paul,

Two questions for you...

First one: If you put a host on that port-profile and try to ping it, are you learning a MAC out of either of your corresponding eth ports?

Second one: Can you post output of "module vem # execute vemcmd show bd" and "module vem # execute vemcmd show trunk"? Where # is the module number of the VEM we're looking at, of course.

Hi Paul,

Whenever I got issues with uplinks there was the recomondation to use "spanning-tree portfast trunk" on the uplink port of your 3750

try this:

interface GigabitEthernet4/0/28

spanning-tree portfast

Chris
