JUNOS 10.1 Network Interfaces Configuration Guide
Configuring Single-Tag Framing
To configure the router to receive and forward single-tag frames with 802.1Q VLAN
tags, include the
level:
Configuring Dual Tagging
To configure the routing platform to receive and forward dual-tag frames with 802.1Q
VLAN tags, include the
interface-name]
Configuring Mixed Tagging
Mixed tagging is supported for Gigabit Ethernet interfaces on Gigabit Ethernet IQ2
and IQ2-E, and IQ or IQE PICs on M Series and T Series routers, for all MX Series
router Gigabit and 10-Gigabit Ethernet interfaces, and for aggregated Ethernet
interfaces with member links in IQ2 and IQ2-E PICs or in MX Series DPCs. Mixed
tagging lets you configure two logical interfaces on the same Ethernet port, one with
single-tag framing and one with dual-tag framing.
NOTE: Mixed tagging is not supported on Fast Ethernet interfaces or on J Series
Services Routers.
To configure mixed tagging, include the
interfaces ge-fpc/pic/port ]
