Juniper EX3400 Features Guide

When you configure the no-vlan-interface-name and use-interface-description statements,
the format displays the IRB interface description:
irb_descr
If you configure the no-vlan-interface-name and use-interface-description statements,
and no description for the IRB interface is found, the format displays the IRB interface
name:
irb.subunit
When you configure the no-vlan-interface-name and include-irb-and-l2 statements, the
format displays the Layer 2 logical interface name and the IRB interface name:
(fe | ge)-fpc/pic/port.subunit+irb.subunit
When you configure the no-vlan-interface-name, include-irb-and-l2 and use-interface-name
statements, the format displays the Layer 2 interface description and the IRB interface
name:
l2_descr+irb.subunit
If you configure the no-vlan-interface-name, include-irb-and-l2 and use-interface-name
statements, and no description for the Layer 2 interface is found, the format displays the
Layer 2 logical interface name and the IRB interface name:
(fe | ge)-fpc/pic/port.subunit+irb.subunit
