Advanced > Advanced Network > UPnP
Universal Plug and Play (UPnP) is a feature that allows the controller to discovery
devices on the network that can communicate with the controller and allow for auto
configuration. If a network device is detected by UPnP, the controller can open internal
or external ports for the traffic protocol required by that network device.
Once UPnP is enabled, you can configure the controller to detect UPnP-supporting
devices on the LAN (or a configured VLAN). If disabled, the controller will not allow
for automatic device configuration.
Configure the following settings to use UPnP:
Advertisement Period: This is the frequency that the controller broadcasts UPnP
information over the network. A large value will minimize network traffic but cause
delays in identifying new UPnP devices to the network.
Advertisement Time to Live: This is expressed in hops for each UPnP packet. This is
the number of steps a packet is allowed to propagate before being discarded. Small
values will limit the UPnP broadcast range. A default of 4 is typical for networks with
few controllers.
