NAME

netopeer2-cli - NETCONF client with command line interface build on libnetconf2

DESCRIPTION

netopeer2-cli serves as a generic NETCONF client providing a simple interactive command line interface. It allows user to establish a NETCONF session with a NETCONF-enabled device on the network and to obtain and manipulate its configuration data. netopeer2-cli is limited to a single NETCONF connection at a time via a forward or a reverse (Call Home) connecting method.

Here is the list of NETCONF capabilities supported by netopeer2-cli:

  • NETCONF protocol version 1.0 and 1.1 (RFC 6241)
  • SSH transport (RFC 6242)
  • TLS transport (RFC 7589)
  • Call Home (RFC 8071)
  • Event Notifications (RFC 5277)
  • Access Control (RFC 6536)
  • :writable-running capability
  • :startup capability
  • :candidate capability
  • :confirmed-commit capability
  • :validate capability version 1.1
  • :with-defaults capability (RFC 6243)
  • :url capability
  • :xpath capability
  • NMDA operations (RFC 8526)
  • YANG Schema Mount (RFC 8528)
  • YANG notification subscriptions (RFC 8639)
  • YANG Push subscriptions (RFC 8641)

TRANSPORT

The supported transport protocols are detected automatically based on how was libnetconf2 compiled. Unsupported (sub)commands are then not available and are hidden in the help. This page, however, contains them all.

COMMANDS

displayown

Shows information about the status of the default client certificates and displays information about any relevant found client certificates ~/.netopeer2-cli/client.crt and ~/.netopeer2-cli/client.pem.

replaceown cert_path [key_path]

Replaces the default client certificates with the PEM certificate in cert_path or the CRT certificate cert_path and private key key_path. All previous client certificates are deleted.
