i.LON SmartServer 2.0 Programmer’s Reference 14-4
Property Description
Specifies the network management service used to manage the
network. This property can be one of the following values:
• SYNC_STANDALONE. The SmartServer is the network
manager. It transmits all network management commands
to the devices attached to its channel, and network
configuration changes are stored in the internal SmartServer
database.
In standalone mode, the network functions as a master-slave
system, where the SmartServer is the master to the slave
devices.
You can use standalone mode to operate a small,
single-channel network that does not require LNS services,
L
ON W ORKS connections, or connections to other network
management tools. FT-10 networks running in standalone
mode are limited to a maximum of 64 devices; PL-20
networks are limited to a maximum of 200 devices.
• SYNC_LNS. Network messages are routed through the
LNS server specified in the property. The
SmartServer and the devices connected to it communicate
in a peer-to-peer manner. In this mode, the SmartServer
independently initiates communication with the LNS Proxy
Web service, and the SmartServer automatically
synchronizes with the LNS network database.
You should use this mode as long as a firewall is not
blocking the SmartServer’s access to the port on the LNS
Server computer selected for the LNS Proxy Web service
(port 80 by default).
• SYNC_NUL. Similar to SYNC_LNS except that the
SmartServer has to be manually synchronized with the LNS
server specified in the property. This
mode does not require the opening of any ports on firewalls
blocking the SmartServer’s access to the LNS Server
computer.
In this mode, the SmartServer Web interface serves as a
proxy between the SmartServer and an LNS Server that is
behind a firewall.
When you manually synchronize the SmartServer to an
LNS network database, the SmartServer Web interface
requests a list of objects to be synced from the SmartServer
via SOAP and forwards the objects returned by the
SmartServer to the LNS Proxy Web service. The LNS
Proxy Web service returns a set of synced objects to the
SmartServer Web interface, which forwards these objects
back to the SmartServer.
You should only use this mode if a firewall is blocking the
SmartServer’s access to the LNS Proxy Web service port on
the LNS Server computer (port 80 by default). This is the
default.
