    The Juniper side of a trunk port would require
    • Create all the vlans that will be included
    • Setting the interface to ethernet switching trunk mode
    • add the vlans via one of two options 
      • Option 1- add the interface to the vlan statement
      • Option 2 - add the vlans to the interface configuration
