NETCONF Operation Steps

NETCONF Operations

NETCONF Operation has three common steps. These steps are:

• Session Establishment
• Operation Request and Reply
• Session Close

Firstly, the Session is Established with the

messages. Both NETCONF Client and NETCONF Server send

message for the negotiation about their capabilities, supported models, versions etc.

After Session Establishment, Operation Request and Reply messages are sent. These messages are for specific operations. Here, the message used for Operation Request is send with

message and the Operation Reply is sent with

message. In other words, NETCONF Client sends its requests to the NETCONF Server with

message. And Server replies with

message.

Lastly, session is closed with

message. Client sends this message and the server replies back with

message.

NETCONF Messages

We have talk about NETCONF Operation Steps and we saw the messages that are sent between NETCONF Client and NETCONF Server. Now, let’s check a little deeply and see the content of these messages.

First of all, let’s start with Hello messages. As you know, Hello messages establishes NETCONF session. These messages includes the capabilities of the sending device.

Now, let’s check Operational RPC Messages. There are two RPC Messages used in NETCONF. All these operations are done within these main messages. These RPC Messages are:
