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.
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.
Mapping Protocol of the VCTRUNKs on
the Ethernet boards of the interconnected
equipment at both ends must be set to the
same value.
In this example, this parameter adopts the
default value Scrambling mode [X43+1].
Scramble of the VCTRUNKs on the
Ethernet boards of the interconnected
equipment at both ends must be set to the
same value.
In this example, this parameter adopts the
default value FCS32. Check Field Length
of the VCTRUNKs on the Ethernet boards of
the interconnected equipment at both ends
must be set to the same value.
Calculated Bit Sequence is set to Big
endian. FCS Calculated Bit Sequence of
the VCTRUNKs on the Ethernet boards of
the interconnected equipment at both ends
must be set to the same value.
