4.8 Configuring EPLAN Services (IEEE 802.1d Bridge)

The EPLAN service (IEEE 802.1d bridge) provides a LAN solution for multipoint-to-multipoint
convergence. This service applies where the user-side data communication equipment connected
to the transmission network does not support VLANs or where the VLAN planning is kept secret
from the network operator.

4.8.1 Networking Diagram

The convergence node needs to exchange Ethernet services with two access nodes at Layer 2.
The two access nodes need not communicate with each other.

4.8.2 Signal Flow and Timeslot Allocation

The Ethernet services of the convergence node are received from an external port, forwarded to
an internal port through Layer 2 switching, encapsulated, and transparently transmitted on the
SDH network. In this way, the node communicates with a remote node.
4.8.3 Configuration Process
At the convergence node NE1, you need to create an EPLAN service (IEEE 802.1d bridge). At
the access nodes NE2 and NE4, you need to configure only transparent transmission EPL
services.

Three branches (F1, F2, and F3) of user F are located at NE1, NE2, and NE4. F1 needs to
communicate with F2 and F3, and requires a 10 Mbit/s bandwidth for communication with
each branch.
The Ethernet equipment of user F provides 100 Mbit/s Ethernet electrical interfaces that
work in auto-negotiation mode and support VLANs. The VLAN IDs and the number of
VLANs, however, are unknown and may change.
The application scenarios where one branch needs to communicate with other branches are as follows:
l Branches F2 and F3 need to communicate with each other.
l Branches F2 and F3 need not communicate with each other.
If branches F2 and F3 need to communicate with each other, skip
Spoke attributes of ports connected to the bridge.
