Configuring a Non-Protection Ring

How to configure a Non-Protection Ring on Huawei OSN 3500

The Huawei Transmission OptiX OSN equipment supports various network level protection schemes, including the linear MSP and ring MSP. Configuring the Protection Subnet on Huawei SDH. In this article, we will learn how to Configure a Non-Protection Ring.

When services on a ring do not need protection, you can configure a non-protection (NP) ring. All timeslots on the ring can be used to transmit services.

Prerequisites

1 You must be an NM user with NE and network maintainer authority or higher.

2 The NE data must be configured, and fibers must be properly created.

Procedure

Step 1 Choose Service > SDH Protection Subnet > Create Unprotected Ring from the Main Menu to display the Create Protection Subnet dialog box.

Step 2 Enter the name of the protection subnet.

The default name is usually used, for example, NP_Ring_1.

Step 3 Select the rate of the protection subnet,

for example, STM-4.

Step 4 Select Resource Sharing and Assigned by VC4 as needed.

NOTE

1 If multiple protection subnets use one port of a board, you need to check the Resource Sharing check box. If MSP Sharing is enabled, you can check the Resource Sharing check box to map a port of the board to multiple MSPs. If different protection subnets use different ports of a board, do not check this check box.

2 Select the Assigned by VC4 option when there are different VC4s belonging to different protection subnets to achieve MSP only in some channels protection. For example, for an STM-16 fiber, the VC4s 1-4 belong to an STM-4 MSP, and VC4s 5-8 belong to a PP.

3 OptiX OSN 1500/2500/3500/3500 II/7500 /7500 II do not support Transoceanic Protocol

Step 5 Add nodes to the protection subnet to be created. Double-click the NE on the Main Topology and add it to the node list in the left-hand pane. Meanwhile, is displayed on the NE icon. If you want to cancel the selection, double-click the NE again.

How to Creat a DLAG

OptiX OSN 7500 II/7500/ OSN 3500 /1500 Configuration Guide: Creating the Network, the second steps: Configuring the Equipment Level Protection. The OptiX OSN equipment supports various equipment level protection schemes, including the

TPS, 1+1 board protection, board level protection, and port protection.

You can set the main/slave relationship and revertive mode for the corresponding ports on two identical boards to provide 1+1 protection for the ports.

Prerequisites

You must be an NM user with NE operator authority or higher.

Background Information

The restrictions on the application of the DLAG function are as follows:

1 The equipment configured with a DLAG must be interconnected with the equipment that

runs the LACP protocol. If any intermediate equipment exists between the two sets of

equipment configured with DLAGs, the intermediate equipment must transparently

transmit the LACP protocol packets.

2 The main/slave relationship can be configured only for two identical boards. Specifically,

the port on the slave board is used to protect only the corresponding port on the main board.

3 One DLAG can contain a maximum of two ports, which must have the same port number.

4 The slave board cannot be configured with services (including Ethernet services, LAG,

cross-connections, LPT, and paths bound to VCTRUNK ports).

5 The bandwidth of the slot where the slave board is installed must be equal to or higher than the bandwidth of the slot where the main board is installed.

6 One Ethernet board cannot be configured with the BPS, PPS, and DLAG protection at the same time.

7 The port configured into a DLAG must be an external physical Ethernet port. In addition,

one port cannot be configured into a DLAG and a LAG at the same time.

8 During the configuration of a DLAG, the attributes of the slave port automatically become consistent with the attributes of the main port.

9 Do not perform a selfloop on an external physical port that needs to be configured into a

DLAG.

10 If Ethernet services are already created, ensure that the level of the timeslots bound to a path is consistent with the level of the configured cross-connections.

11 If Ethernet services are already created, ensure that the external physical port that needs to be configured into a DLAG does not share the same VCTRUNK port with other external physical ports.

12 One external physical port of a DLAG may correspond to multiple VCTRUNK ports; one VCTRUNK port, however, can correspond to only one external physical port of a DLAG.

Therefore, the external physical ports of different DLAGs cannot be configured into one

virtual bridge (VB), because one VCTRUNK may correspond to multiple external physical

ports in such a case.

Procedure

Step 1 In the NE Explorer, select the required NE and choose Configuration > Ethernet Distributed Link Aggregation Management from the Function Tree.

Step 2 Click New.

Step 3 In the Create Distributed Link Aggregation Group dialog box that is displayed, set the attributes and ports of the DLAG.

Step 4 Click OK.

Step 5 Create a DLAG on the Huawei SDH interconnected NE at the opposite end.

----End

Follow-up Procedure

1. Change of Revertive Mode of a DLAG

Change of Revertive Mode does not affect the services carried by the DLAG.

2. Deletion of a DLAG

l When the DLAG on the equipment at one end is deleted, the equipment at the opposite

end starts link re-negotiation. In this case, the DLAG_PROTECT_FAIL alarm is

reported but the services are not interrupted.

                                                  

l When the DLAGs on the interconnected equipment at both ends are deleted at the same

time, the services are not interrupted.

How to Creat a LAG

Huawei Transmission OptiX OSN 7500 II/7500/ OSN 3500/1500 Configuration Guide: Creating the Network, the second steps: Configuring the Equipment Level Protection. The OptiX OSN equipment supports various equipment level protection schemes, including the

TPS, 1+1 board protection, board level protection, and port protection.

Link aggregation allows all the members in a LAG to share incoming and outgoing service loads, increasing bandwidth. In addition, the members in the LAG provide dynamic backup for each other, providing more reliable connections.

Prerequisites

1 You must be an NM user with NE operator authority or higher.

2 The slave port cannot be configured with services.

3 The Ethernet ports configured in a LAG must work in full-duplex mode and at the same

rate.

4 An Ethernet port and a VCTRUNK port cannot be configured into the same LAG.

Procedure

Step 1 In the NE Explorer, select the required Ethernet board and choose Configuration > Ethernet Interface Management > Ethernet Link Aggregation Management from the Function Tree.

Step 2 Click the Link Aggregation Group Management tab, and then click New. In the Create Link Aggregation Group dialog box that is displayed, set the required parameters.

Step 3 Click OK. In the dialog box that is displayed, click Close.

Step 4 Optional: Click the Link Aggregation Parameters tab. Set Port Priority and System

Priority.

NOTE

1 A port ID consists of Port and Port Priority. The port that has the smallest port ID in a LAG is always aggregated first.

2 A system ID consists of System Priority and System MAC Address. When a system negotiates with the remote system, the system with the smallest system ID can always choose the port to be aggregated first. In this example, the system refers to the board, and accordingly the system MAC address refers to the MAC address of the board. The factory-set MAC address is globally unique and cannot be modified.

----End

Deleting a LAG

1 When the LAG on the equipment on one side is deleted, the services carried by the LAG

are interrupted and the LAG_DOWN alarm is reported.

2 When the LAGs on the interconnected equipment on both sides are deleted at the same

time, the services are interrupted during the deletion. The services, however, are restored

after the deletion.

Creating Inter-Board Port Protection Groups

OptiX OSN 7500 II/7500/3500/1500 Configuration Guide: Creating the Network, the second steps: Configuring the Equipment Level Protection. The OptiX OSN equipment supports various equipment level protection schemes, including the

TPS, 1+1 board protection, board level protection, and port protection. Addition: OSN 8800 the different version the configuration would be different.

Creating Inter-Board Port Protection Groups

The inter-board port protection switching (PPS) is a protection scheme based on ports between boards. This protection scheme requires an active board and a standby board. When the active board detects a link down failure of any port, or detects a board hardware failure, the crossconnect board on the equipment switches the services of one or more affected ports to the standby board. In this case, a protection switching of the entire board is not required. Compared with the board protection switching (BPS), the PPS has less impact on external systems and the network.

Prerequisites

1 You must be an NM user with NE operator authority or higher.

2 The Ethernet boards must be installed in pairs. There must be no services on the protection board.

3 The available bandwidth of the protection board is higher than or equal to the available

bandwidth of the working board. In addition, the interface boards must be of the same type

and quantity.

4 The same EMS4/EGS4 board cannot be configured with BPS and PPS simultaneously.

5 Before configuring the PPS for the Huawei SDH EMS4 board, you must set the working mode of the

corresponding interface board such as N1ETF8/N1EFF8 to 100M full-duplex.

Context

When the following prerequisites are met, the protection group can be switched automatically.

1 The equipment that is interconnected with the protection group has the same working mode as that of the protection group.

2 The transmit end and the receive end should be connected directly through optical fibers

or network cables. There should be no equipment between the two ends.

3 The working mode at the receive end should not be modified before the protection group

is deleted. Otherwise, the protection group works abnormally.

NOTE

1 After the inter-board port protection group is created, the protection port cannot be used to transmit other services.

2 Add all the ports to the port protection group when you configure an inter-board port protection group.

3 The N1EMS4, N1EGS4, and N3EGS4 boards support the inter-board port protection.

4 Configuration of the intra-board port protection is similar to the configuration of the inter-board port protection. The difference is that the configuration of the intra-board port protection is based on different ports on the same board.

Procedure

Step 1 In the NE Explorer, select an NE and choose Configuration > Port Protection from the Function Tree.

Step 2 Click New and the Create Port Protection Group dialog box is displayed.

Step 3 Enter Protection Group ID, select Working Port and Protection Port.

NOTE

If you directly click OK without specifying the Protection Group ID, the system automatically allocates the protection group ID. Click OK in the Warning dialog box.

Step 4 Click OK. A prompt dialog box is displayed, indicating that the operation is successful.

Step 5 Click Close.
