AppNote - NETCONF Call Home and ConfD

Phone Home, Network Element

NETCONF Call Home and ConfD ImageConnections between network elements can be tricky with all of the restrictions and security required to function in today’s networks. NETCONF Call Home enables a NETCONF server in a network element to "call home" to a NETCONF client in a controller or orchestrator.

NETCONF Call Home can be leveraged for both the initial deployment and ongoing management of networking elements. Some of the use cases include:

  • Allowing access which is normally prevented by NAT/firewall boundaries between peers
  • Proactively registering a networking element with a management system
  • Enabling an ad-hoc management interface without permanently opened networking ports
