Logical Units

Hello to all,


When i try to assign a secondary logical interface on a physical interface (unit 2) i get this error message:


[edit interfaces reth2]

  'unit 1'

    Only unit 0 is valid for this encapsulation

error: configuration check-out failed


te only way to configure unit 1 or unit 2 is tagging the interface?


Thanks and regards.

If You are not using "vlan-tagging" knob, only one unit is allowed on Ethernet interface and it has to be unit 0.

It may help to think about JUNOS units as Cisco IOS subinterfaces: AFAIR, one is not allowed to configure >1 Ethernet subinterface if "encapsulation dot1q XYZ" is not used.
