The services of multiple users received from the same external port on an Ethernet board of a
station are transmitted to different stations on different VCTRUNKs.
Service Requirement
In the network as shown in
, the service requirements are as follows:
l
The headquarters C1 of user C is located at NE1. Two branches (C2 and C3) of user C are
located at NE2 and NE4. The services between C1 and C2 are transmitted in the VLAN of
which the VLAN ID is 100. The services between C1 and C3 are transmitted in the VLAN
of which the VLAN ID is 200.
l
The services of C2 are isolated from the services of C3. The services of C2 and C3 require
a 20 Mbit/s bandwidth respectively.
l
The Ethernet equipment of C1, C2, and C3 provides 100 Mbit/s Ethernet electrical
interfaces that work in auto-negotiation mode. The Ethernet equipment of C1 supports
VLANs, but the Ethernet equipment of C2 and C3 does not support VLANs.
–
The VLAN ID used by the Ethernet services between C1 and C2 is 100.
–
The VLAN ID used by the Ethernet services between C1 and C3 is 200.

Board Configuration Information
In this example, NE1 is configured with an EFS8 board. VLAN IDs are used to isolate the data
of different users received from the same port. NE2 and NE4 are each configured with an EGT1
