UPnP Discovery
UPnP (Universal Plug and Play) allows for automatic discovery of devices that can
communicate with your security appliance. The UPnP Portmaps table displays the
port mapping entries of the UPnP-enabled devices that accessed your security
appliance.
Click Device Management > Discovery Protocols > UPnP.
Enter the following information:
•
Universal Plug-n-Play (UPnP): Click On to enable UPnP, or click Off to
disable UPnP. If UPnP is disabled, the security appliance will not allow for
automatic device configuration.
•
LAN: Choose an existing VLAN to which the UPnP information is
broadcasted and listened on.
•
Advertisement Period: Enter the value in seconds of how often the security
appliance broadcasts its UPnP information to all devices within range. The
default value is 1800 seconds.
•
Advertisement Time to Live: Enter the value 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.
The default value is 4.
Click Save to apply your settings.
After you enable UPnP, the information in the UPnP Portmaps table will be
refreshed immediately. Click Refresh to manually refresh the data.
