+
+ <p>NETCONF client module.</p>
+
+ <p>The NETCONF client is compliant with RFC 4741 NETCONF Configuration
+ Protocol and RFC 4742 Using the NETCONF Configuration Protocol over
+ Secure SHell (SSH)..</p>
+
+ <p>For each server to test against, the following entry can be added to a
+ configuration file:</p>
+
+ <pre>
+ {server_id(),options()}.</pre>
+
+ <p>The <c>server_id()</c> or an associated <c>target_name()</c> (see
+ module <seealso marker="ct"><c>ct</c></seealso>) must then be used
+ in calls to
+ <seealso marker="#open-2"><c>ct_netconfc:open/2</c></seealso>.</p>
+
+ <p>If no configuration exists for a server, a session can still be
+ opened by calling
+ <seealso marker="#open-2"><c>ct_netconfc:open/2</c></seealso> with
+ all necessary options specified in the call. The first argument to
+ <seealso marker="#open-2"><c>ct_netconfc:open/2</c></seealso> can
+ then be any atom.</p>

+ <section>
+ <marker id="Logging"/>
+ <title>Logging</title>
+ <p>The NETCONF server uses <c>error_logger</c> for logging of NETCONF
+ traffic. A special purpose error handler is implemented in
+ <c>ct_conn_log_h</c>. To use this error handler, add the
+ <c>cth_conn_log</c> hook in the test suite, for example:</p>
+
+ <pre>
+ suite() -&gt;
+ [{ct_hooks, [{cth_conn_log, [{conn_mod(),hook_options()}]}]}].</pre>
+
+ <p><c>conn_mod()</c> is the name of the <c>Common Test</c> module
+ implementing the connection protocol, for example, <c>ct_netconfc</c>.</p>
+
+ <p>Hook option <c>log_type</c> specifies the type of logging:</p>
+
+ <taglist>
+ <tag><c>raw</c></tag>
+ <item><p>The sent and received NETCONF data is logged to a separate
+ text file "as is" without any formatting. A link to the file is
+ added to the test case HTML log.</p>.</item>
+
+ <tag><c>pretty</c></tag>
+ <item><p>The sent and received NETCONF data is logged to a separate
+ text file with XML data nicely indented. A link to the file is
+ added to the test case HTML log.</p></item>
+
+ <tag><c>html (default)</c></tag>
+ <item><p>The sent and received NETCONF traffic is pretty printed
+ directly in the test case HTML log.</p></item>
+
+ <tag><c>silent</c></tag>
+ <item><p>NETCONF traffic is not logged.</p></item>
+ </taglist>
+
+ <p>By default, all NETCONF traffic is logged in one single log file.
+ However, different connections can be logged in separate files.
+ To do this, use hook option <c>hosts</c> and list the names of the
+ servers/connections to be used in the suite. The connections
+ must be named for this to work, that is, they must be opened with
+ <seealso marker="#open-2"><c>ct_netconfc:open/2</c></seealso>.</p>
+
+ <p>Option <c>hosts</c> has no effect if <c>log_type</c> is set to
+ <c>html</c> or <c>silent</c>.</p>
+
+ <p>The hook options can also be specified in a configuration file with
+ configuration variable <c>ct_conn_log</c>:</p>
+
+ <pre>
+ {ct_conn_log,[{conn_mod(),hook_options()}]}.</pre>
+
+ <p>For example:</p>
+
+ <pre>
+ {ct_conn_log,[{ct_netconfc,[{log_type,pretty},
+ {hosts,[key_or_name()]}]}]}</pre>
+
+ <note>
+ <p>Hook options specified in a configuration file overwrite the
+ hard-coded hook options in the test suite.</p>
+ </note>
+
+ <p><em>Logging Example 1:</em></p>
+ <marker id="Logging_example_1"/>
+
+ <p>The following <c>ct_hooks</c> statement causes pretty printing of
+ NETCONF traffic to separate logs for the connections named
+ <c>nc_server1</c> and <c>nc_server2</c>. Any other connections are
+ logged to default NETCONF log.</p>
+
+ <pre>
+ suite() -&gt;
+ [{ct_hooks, [{cth_conn_log, [{ct_netconfc,[{log_type,pretty}},
+ {hosts,[nc_server1,nc_server2]}]}
+ ]}]}].</pre>
+
+ <p>Connections must be opened as follows:</p>
+
+ <pre>
+ open(nc_server1,[...]),
+ open(nc_server2,[...]).</pre>
+
+ <p><em>Logging Example 2:</em></p>
+ <marker id="Logging_example_2"/>
+
+ <p>The following configuration file causes raw logging of all NETCONF
+ traffic in to one single text file:</p>
+
+ <pre>
+ {ct_conn_log,[{ct_netconfc,[{log_type,raw}]}]}.</pre>
+
+ <p>The <c>ct_hooks</c> statement must look as follows:</p>
+
+ <pre>
+ suite() -&gt;
+ [{ct_hooks, [{cth_conn_log, []}]}].</pre>
+
+ <p>The same <c>ct_hooks</c> statement without the configuration file
+ would cause HTML logging of all NETCONF connections in to the test
+ case HTML log.</p>
+ </section>
+
+ <section>
+ <marker id="Notifications"/>
+ <title>Notifications</title>
+
+ <p>The NETCONF client is also compliant with RFC 5277 NETCONF Event
+ Notifications, which defines a mechanism for an asynchronous message
+ notification delivery service for the NETCONF protocol.</p>
+
+ <p>Specific functions to support this are
+ <seealso marker="#create_subscription-6"><c>ct_netconfc:create_subscription/6</c></seealso>
+ and
+ <seealso marker="#get_event_streams-3"><c>ct_netconfc:get_event_streams/3</c></seealso>.
