Re: Subinterfaces vs VLAN interfaces

Sorry for the confusion adwivedl. What I'm finding in researching is you can either config as:

Specify a new VLAN, which will be used for switching, in this case vlan 100:
user@host# set vlans vlan-100 vlan-id 100

Assign this VLAN interface as your Layer3 Interface on this VLAN:
user@host# set vlans vlan-100 l3-interface vlan.100

Configure a VLAN interface with an IP for this VLAN.   (It must be on a different L3 subnet than the other VLANs.)
user@host# set interfaces vlan unit 100 family inet address 192.168.10.1/24

  When you do that, I'm finding (if I read right) that you config the physical interface:

set interfaces ge-0/0/0 unit 0 description ge-0/0/1
set interfaces ge-0/0/0 unit 0 family ethernet-switching port-mode trunk/access
set interfaces ge-0/0/0 unit 0 family ethernet-switching vlan members vlan-name [names]
set interfaces ge-0/0/0 unit 0 family ethernet-switching native-vlan-id 3

The other example I've found is just configure sub-interfaces on the physical interface:

set interfaces ge-0/0/0 vlan-tagging
set interfaces ge-0/0/0 native-vlan-id 100
set interfaces ge-0/0/0 unit 100 vlan-id 100
set interfaces ge-0/0/0 family inet address 192.168.1.1/24

set interfaces ge-0/0/0 unit 200 vlan-id 200
set interfaces ge-0/0/0 family inet address 192.168.2.1/24

set interfaces ge-0/0/0 unit 300 vlan-id 300
set interfaces ge-0/0/0 family inet address 192.168.3.1/24
