Entry
Detectio
n
VCTRUNK1: Enabled
VCTRUNK1 is used by the service between
user D1 and user D2 and the service between
user E1 and user E2. Then, you need to enable
the entry detection function to detect the
VLAN tags of the received packets.

Value in This Example Description
Port
Attribut
es
VCTRUNK1: UNI
UNI indicates the user-network interface,
namely, the interface of the service provider
located near the user side. The UNI interface
processes the tag attribute of IEEE 802.1Q-
compliant packets. That is, the UNI interface
processes and identifies the VLAN
information of the accessed user packets,
according to the supported tag flag, namely,
Tag Aware
,
Access
, and
Hybrid
.
