+    The <emphasis>set-config</emphasis> command instructs the server to replace
+    its current configuration with the new configuration supplied in the
+    command's arguments. The supplied configuration is expected to be the full
+    configuration for the target server along with an optional Logger
+    configuration.  While optional, the Logger configuration is highly
+    recommended as without it the server will revert to its default logging
+    configuration. The structure of the command is as follows:
+      </para>
+<screen>
+{
+    "command": "set-config",
+    "arguments":  {
+        "&#60;server&#62;": {
+        },
+        "Logging": {
+        }
+     }
+}
+</screen>
+      <para>
+    where &#60;server&#62; is the configuration element name for a given server
+    such as "Dhcp4" or "Dhcp6".  For example:
+      </para>
+<screen>
+{
+    "command": "set-config",
+    "arguments":  {
+        "Dhcp6": {
+            :
+        },
+        "Logging": {
+            :
+        }
+     }
+}
+</screen>
+      <para>
+    If the new configuration proves to be invalid the server will retain
+    its current configuration.  Please note that the new configuration is
+    retained in memory only.  If the server is restarted or a configuration
+    reload is triggered via a signal, the server will use the configuration
+    stored in its configuration file.
+
+       The server's response will contain a numeric code, "result" (0 for success,
+    non-zero on failure), and  a string, "text", describing the outcome:
+<screen>
+    {"result": 0, "text": "Configuration successful." }
+
+    or
+
+    {"result": 1, "text": "unsupported parameter: BOGUS (&#60;string&#62;:16:26)" }
