NETCONF configuration OLT

Hi,

Introduction

Network Configuration Protocol (NETCONF) is a key technology that simplifies complex network configuration.

Background

With the development of networks, the types and number of communication devices increase rapidly. Traditional Command Line Interface (CLI) or Simple Network Management Protocol (SNMP) configuration methods cannot adapt to the management of complex networks. Especially when devices from multiple vendors exist on the same network, the management methods of devices from different vendors are independent of each other, and the operations are complex. Therefore, automatic configuration is difficult to implement. To resolve this issue, the NETCONF protocol based on Extensible Markup Language (XML) and structured data model defined based on YANG are developed.

Definition

NETCONF provides mechanisms to add, modify, delete, and query the configurations of network devices, and obtain the network device status. With NETCONF, network devices can provide standard application programming interfaces (APIs). Applications can directly use these APIs to send configurations to or obtain configurations from network devices. NETCONF can directly use the existing functional modules of devices. This reduces the development cost of NETCONF and allows users to use new features supported by the devices at any time.
YANG defines a structured data model. It is a machine-oriented model interface, and defines the data structure and constraints to describe data more flexibly and completely.

Value

NETCONF complies with YANG model constraints to implement communication between clients and servers. With standardized deployment, network administrators can use NETCONF to uniformly manage, configure, and monitor various network devices that support YANG, simplifying O&M and reducing O&M costs.

Compared with traditional configuration protocols, NETCONF is more convenient on man-machine interfaces and machine-to-machine interfaces. Table 1 shows the comparison between SNMP and NETCONF.

**Table 1** Comparison between NETCONF and SNMP
Comparison Item	SNMP	NETCONF
Configuration management	Does not provide the protection lock mechanism when multiple users perform operations on the same configuration.	Provides the protection lock mechanism to prevent conflicts caused by multi-user operations.
Query	Supports the query for one or more records in a table but requires multiple interactions.	Supports the direct query for the configuration data of the system, and supports filtering on data query.
Scalability	Poor expansibility	Good expansibility SNMP models are defined by layer and each layer is independent of each other. Extensions to one layer have little effect on the other layers. NETCONF is in the XML encoding format. This expands the management capability and system compatibility of NETCONF.
Security	The SNMPv3 security protocol has no room for expansion.	NETCONF uses existing security protocols to ensure network security, and is not specific to any security protocols. This enables users to flexibly select a security protocol.

Configuring NETCONF

Configure Network Configuration Protocol (NETCONF) to implement remote communication between the network management system (NMS) and devices.

Networking Diagram

As shown in Figure 1, when NETCONF is configured, the NETCONF Manager functions as the client and the NMS is deployed. The NETCONF Agent functions as the SSH server and receives the connection from the NETCONF Manager that functions as the SSH client. In this way, the configuration file can be managed through NETCONF.

Figure 1 NETCONF Scenario

Procedure

Run the sysman server source command to bind a specified source interface.

In V100R018C00SPC600, V100R019C11SPC300, V100R020C00, and later versions, you must perform this step for the NETCONF function to take effect.
Enable NETCONF on the NETCONF agent and create a device user.
Deploy the NMS on the NETCONF Manager.
Log in to the NETCONF Agent from the NETCONF Manager using the NMS.
Verify the configuration.

Example

Example:

Bind the NETCONF service protocol to a specified source port. Set the port type to vlanif and the port index to 300.

Enable NETCONF and set the user name and password. Here, V100R020C10 is used as an example. For other versions, the actual display prevails.
