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.
