This attribute provides an improved layer of security between Metasys Site Directors and devices. With this attribute set to True, backward compatible methods of communication between the Site Director and its network engines are disabled, which means a Site Director at Release 10.0 or later discards all communication attempts from network engines prior to Release 10.0. This setting applies to the entire site, so change this attribute to False if you have any network engines on the site that are running a Metasys release prior to Release 10.0.
When you change this attribute to True, a user message appears to indicate that all network engines prior to Release 10.0 remain online, but are disconnected from the site because they no longer communicate with the Site Director. If this message appears, click OK to continue and set the attribute to True, or Cancel to keep the attribute set to False.
