The NETCONF protocol operations are realized as remote procedure calls (RPCs).” NETCONF protocol layers NETCONF is connection oriented. A client sends series of one or more RPC requests, which causes the server to respond with rpc reply. There are 2 ways of establishing NETCONF sessions: Normal : client initiates the connection towards server Call Home : NETCONF server initiates connection towards NETCONF client Datastores Running : mandatory Startup Candidate Operational : running datastore (if backend updates any value, then that value will be shown and not running datastore) + ro Data Model access Xpath based Subtree filtering NETCONF Operations Following is the list of som...
