Question Description

How to upgrade the smart network element in Huawei OSN1500 devices?

Solution

The host software must be the version that supports intelligent features, the master subrack is a dual master configuration, and the supporting shipped network management must be the version that supports intelligent features.

ASON features are controlled by the License on the network management, and you are allowed to turn on the smart features only if you have applied for and purchased a License for the ASON feature management function or received a special license from Huawei.

Steps to configure intelligent network elements:

Check the consistency of the logical veneer with the physical veneer.

Inconsistency between the types of logical and physical veneers will cause the veneers to fail to work properly, affecting the services. Therefore, you should check the consistency of the logical single board and the physical single board before tuning the service.

1、Set the DCC working mode

Before starting the intelligent software, you need to query the DCC working mode of the network element and reset the DCC working mode.

2、Modify the node ID

Node ID is independent of network element ID and network element IP. In an ASON network, each intelligent network element is configured with a unique node ID throughout the network to identify the network element. It is required to determine the configuration of the node ID when planning the network.

3. Enabling Intelligent Features

A network element has smart features only after enabling smart features. When the device is shipped from the factory, the smart feature is disabled by default.

4.Uploading Network Element Configuration Data

During the device tuning process, the network element data already exists on the network management. After enabling the intelligent characteristics of the intelligent network element, you can no longer perform initialization operations on the network element, nor can you perform data download operations on the network element. You need to perform data upload operations after enabling and disabling smart features to ensure that the data on the network management side and the network element side are consistent.

5. Creating Intelligent Domain

The network manager manages the intelligent network in the form of intelligent domains, which are usually created automatically. Network elements that are not synchronized to the intelligent domain during the upload process for some reasons can be divided into a domain by creating a domain that belongs to the same intelligent network elements of the ASON network.

6. Synchronizing Intelligent Network Elements

Network synchronization is performed through the main network element to automatically discover other intelligent network elements in the network.

7、Setting up primary and backup network elements

In the ASON network, each intelligent network element has access to the topology information of the whole network. The main network element is used as the network element that communicates with the network manager and is responsible for obtaining intelligent control plane information and reporting intelligent events to the network manager. To improve the reliability, a backup network element can be set up as a backup for the main network element. In case of failure of the primary network element, the backup network element replaces the primary network element and maintains the communication between the ASON and the network management. Usually, the gateway network element is selected as the primary or backup network element to avoid wasting ECC bandwidth.

8、Synchronize the whole network control link

Synchronize the control links so that the control link data in the network management is consistent with the control link data on the network element side of the ASON network.

9、Synchronize TE links

Get the link resources of the whole network by querying the main network element, so that the link data in the network management is consistent with the ASON network.

10、Automatic creation of fiber

Automatically create fibers between intelligent network elements through network management.
