In the example configuration above, ge-1/1/0 supports single-tag logical interfaces, and
ge-1/1/1 supports mixed tagging. The single-tag logical interfaces ge-1/1/0.10 and
ge-1/1/1.20 each bundle lists of VLAN IDs. The dual-tag logical interface ge-1/1/1.20
bundles lists of inner VLAN IDs.

TIP: You can group a range of identical interfaces into an interface range and
then apply a common configuration to that interface range. For example, in
the above example configuration, both interfaces ge-1/1/0 and ge-1/1/1 have
the same physical encapsulation type of flexible-ethernet-services. Thus you
can define an interface range with the interfaces ge-1/1/0 and ge-1/1/1 as its
members and apply the encapsulation type flexible-ethernet-services to that
defined interface range. For more information about interface ranges, see
Configuring Interface Ranges.

Associating VLAN IDs to VLAN Demux Interfaces
The following sections describe how to configure VLAN demux interfaces to receive and
forward VLAN-tagged frames:

Associating VLAN IDs to VLAN Demux Interfaces Overview
64
To configure a VLAN demux interface to receive and forward VLAN-tagged frames, you
must associate a VLAN ID or dual tagged (stacked) VLAN ID to the interface. Table 5 on
page 64 shows the configuration statements you use to associate VLAN IDs to VLAN
demux interfaces, depending on the VLAN tag framing you use:
Table 5: Configuration Statements Used to Associate VLAN IDs to VLAN Demux Interfaces
Statement
Format
Single-Tag Framing
vlan-id vlan-id;
Dual-Tag Framing
vlan-tags outer tpid. inner tpidvlan-id;
You can include all of the statements at the following hierarchy levels:
• [edit interfaces interface-name unit logical-unit-number]
• [edit logical-systems logical-system-name interfaces interface-name unit
logical-unit-number]
• [edit interfaces demux0 unit logical-unit-number]
