CLI Transport Provider

CLI Transport Provider Overview

The CLI Transport Provider acts as a bridge between the core CLI API and the device. It also aids the CLI API to communicate with any protocol stack. Thus the CLI Transport Provider makes WebNMS CLI API protocol independent.

The CLI Transport Provider is an entity that provides services of a transport interface and the CLI Session is an entity that requires and utilizes these services. The session accesses the services of the transport provider by issuing the appropriate service requests. Service request is a command sent to the device to get / set device details or to start a service. Service event is an autonomous message sent by the device. CLI Transport Provider offers various services like establishing a connection to the devices, sending requests, receiving autonomous messages and responses, etc. The figure below shows the flow of data between the CLI Session and the Network Device.

Some of the key features of the CLI Transport Provider are:

• Supports multiple protocols: The framework allows the user to plug in a provider implementation for any custom transport protocol.
• Supports protocol specific configuration: The parameters specific to the protocol can be configured using the CLI ProtocolOptions interface.
• Provides reference implementations: Reference protocol implementations are provided for Telnet, SSH (SSH1 and SSH2), Serial/RS232, etc.
