Vlan And S-Vlan References; Creating A Vlan Subinterface; Creating A Vlan Major Interface - Juniper JUNOSE SOFTWARE 11.0.X - LINK LAYER CONFIGURATION GUIDE 4-1-2010 Configuration Manual

JUNOSe 11.0.x Link Layer Configuration Guide
For ERX7xx models, ERX14xx models, and ERX310 router, use the
slot/port[.subinterface ] format. For example, the following command specifies a
VLAN subinterface configured on port 0 of an I/O module in slot 4.
For E120 and E320 routers, use the slot/adapter/port[.subinterface ] format, which
includes an identifier for the bay in which the I/O adapter (IOA) resides. For example,
the following command specifies a VLAN subinterface configured on port 0 of the
IOA installed in the upper adapter bay of slot 3.
For more information about interface types and specifiers on E Series models, see
Interface Types and Specifiers in JUNOSe Command Reference Guide.

Creating a VLAN Subinterface

Ethernet interfaces support IP, PPPoE, MPLS, or both IP and PPPoE on each VLAN.
In addition to a VLAN major interface level, a VLAN subinterface level distinguishes
the VLAN.
NOTE: You cannot configure VLANs on the Fast Ethernet port of the SRP module.
Tasks to configure VLAN subinterface are:

Creating a VLAN Major Interface

To use VLANs, you must first configure the Ethernet interface for VLAN encapsulation.
This creates the VLAN major interface. For example:
