Locking the configuration

# Copy the following text to the client to lock the configuration:

<?xml version="1.0" encoding="UTF-8"?>
  <rpc message-id="100" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
    <lock>
      <target>
        <running/>
      </target>
    </lock>
  </rpc>

After receiving the lock request, the device returns a response in the following format if the <lock> operation is successful:

<?xml version="1.0" encoding="UTF-8"?>
  <rpc-reply message-id="100" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
     <ok/>
</rpc-reply>
