Hello Expert

I have a trunk on a Nexus 1000V Interface

interface Ethernet3/7
  inherit port-profile MY-UPLINK

interface Ethernet3/8
  inherit port-profile MY-UPLINK

++++++++++++++++++++

port-profile type ethernet MY-UPLINK
  vmware port-group
  switchport mode trunk
  switchport trunk allowed vlan 500, 600, 700                                          
  no shutdown
  system vlan 500
  state enabled
++++++++++++++++++++

Vlan 600 will be in Future a Private Vlan associated wit private Vlan 601 and 602

##
sh feature
conf t
fearture private-vlan
vlan 601 private-vlan isolated
vlan 602 private-vlan isolated


vlan 600 private-vlan primaery
private-vlan association 601, 602

##################################################

is the Trunk Config Ok like this?

++++++++++++++++++++

port-profile type ethernet MY-UPLINK
  vmware port-group
  switchport mode trunk
  switchport trunk allowed vlan 500, 600, 601, 602, 700

Why do you want to do that? A private vlan separates the vlan into separate broadcast domains, trunks connect switches and extend vlans and broadcast domains so you can add hosts anywhere in the switch mesh, the trunk port is not where you want to implement PVLANs.

You config is technically correct.  But if the Nexus switches are all operating as layer 2 devices, they will not route traffic between VLAN's anyway.  If you want an isolated VLAN on the Nexus switches, simply do not allow that VLAN to pass across the uplinks to your core switch/router (or where the intra VLAN routing is taking place)
