    Private-VLAN Configuration

    Kenard Lawson

      I am currently creating private-vlans on a 3560G switch. However it does not accept the the following commands when configuring the switchports;

       

      switchport mode private-vlan host
      switchport mode private-vlan promisc

       

      under the interfaces. Would that affect the operation of the private vlan? I am unable to test config as no end hosts are currently connected to switch. Config can be seen below..

       

      Thanks
