Configuring EPLAN Services (IEEE 802.1d Bridge)

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.

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.

Service Requirement

In the network as shown in Figure 2-75, the service requirements are as follows:

  • 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.
NOTE:

The application scenarios where one branch needs to communicate with other branches are as follows:

  • Branches F2 and F3 need to communicate with each other.
  • Branches F2 and F3 need not communicate with each other.

If branches F2 and F3 need to communicate with each other, skip 1.d in which you change the Hub/Spoke attributes of ports connected to the bridge.

Figure 2-75  Networking diagram for configuring EPLAN services (IEEE 802.1d bridge)

NOTE:

This topic considers the OptiX OSN 550 as an example to describe the board layout. In the case of other products, the configuration method is the same, except for the slots. For the slot information, see the Hardware Description of the relevant product.

Board Configuration Information

For the EPLAN (IEEE 802.1d bridge) services supported by Ethernet switching boards, refer to Table 2-152.

In this example, the convergence node NE1 is configured with an EFS8 board that supports the IEEE 802.1d bridge to implement EPLAN services wherein user VLANs are not limited.

The access nodes NE2 and NE4 each are configured with an EGT1 board. The EPL services are configured to be transparently transmitted from NE2 and NE4 to NE1.

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.

Figure 2-76 shows the signal flow of the EPLAN services (IEEE 802.1d bridge) and the timeslot allocation to the EPLAN services (IEEE 802.1d bridge).

For the method of calculating the bandwidth of the Ethernet services carried by a VCTRUNK, see Ethernet Service Bandwidths Carried by VCTRUNKs of Ethernet Boards.

Figure 2-76  Signal flow of and timeslot allocation

  • The Ethernet LAN service of user F occupies the first to fifth VC-12 timeslots of the first VC-4 (VC4-1:VC12:1-5) on the SDH link from NE1 to NE2 and the first to fifth VC-12 timeslots of the first VC-4 (VC4-1:VC12:1-5) on the SDH link from NE1 to NE4.
  • The Ethernet LAN service from NE1 to NE2 is added and dropped by using the first to fifth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:1-5) on the EFS8 board of NE1 and the first to fifth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:1-5) on the EGT1 board of NE2.
  • The Ethernet LAN service from NE1 to NE4 is added and dropped by using the sixth to tenth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:6-10) on the EFS8 board of NE1 and the first to fifth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:1-5) on the EGT1 board of NE4.
