NETCONF over BEEP
First Published: June 19, 2006
Last Updated: June 19, 2006
The NETCONF over BEEP feature allows you to enable either the NETCONF server or the NETCONF 
client to initiate a connection, thus supporting large networks of intermittently connected devices and 
those devices that must reverse the management connection where there are firewalls and network 
address translators (NATs). 
The Network Configuration Protocol (NETCONF) defines a simple mechanism through which a network 
device can be managed, configuration data information can be retrieved, and new configuration data can 
be uploaded and manipulated. NETCONF uses Extensible Markup Language (XML)-based data 
encoding for the configuration data and protocol messages. 
Blocks Extensible Exchange Protocol (BEEP) can use the Simple Authentication and Security Layer 
(SASL) profile to provide simple and direct mapping to the existing security model. Alternatively, 
NETCONF over BEEP can use the transport layer security (TLS) to provide a strong encryption 
mechanism with either server authentication or server and client-side authentication. 
NETCONF over BEEP sends notifications of any configuration change over NETCONF. A notification 
is an event indicating that a configuration change has happened. The change can be a new configuration, 
deleted configuration, or changed configuration. The notifications are sent at the end of a successful 
configuration operation as one message showing the set of changes, rather than individual messages for 
each line in the configuration that is changed.
