Wireless Cable Voice Gateway Model CVG824G Reference Manual
•Advertisement Period. The number entered in this field (in minutes) determines how often the router will advertise (broadcast) its UPnP information. This value can range from 1 to 1440 minutes. The default period is for 30 minutes.
–Shorter durations will ensure that control points have current device status at the expense of additional network traffic.
–Longer durations may compromise the freshness of the device status but can significantly reduce network traffic.
•Advertisement Time To Live. The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. A hop is the number of steps allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, then you may need to increase this value a little.
•UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP device that is currently accessing the router and which ports (internal and external) that device has opened. The UPnP Portmap Table also displays what type of port is opened and if that port is still active for each IP address.
To activate UPnP:
1.Check the Turn UPnP On radio box.
2.Click Apply.
To Save, Cancel or Refresh the Table:
•Click Apply to save the new settings to the gateway router.
•Click Cancel to disregard any unsaved changes.
•Click Refresh to update the portmap table and to show the active ports that are currently opened by UPnP devices.
