2-15 UPnP
UPnP is an acronym for Universal Plug and Play. The goals of UPnP are to allow devices to
connect seamlessly and to simplify the implementation of networks in the home (data sharing,
communications, and entertainment) and in corporate environments for simplified installation
of computer components.
Web Interface
To configure the UPnP Configuration in the web interface:
1. Click Configuration, UPnP.
2. Scroll to select the mode to enable or disable.
3. Specify the parameters in each blank field.
4. Click the save to save the setting.
5. If you want to cancel the setting then you need to click the Reset button.
It will revert to previously saved values.
Figure 2-15: The UPnP Configuration
Parameter description:
These parameters are displayed on the UPnP Configuration page:
Mode
Indicates the UPnP operation mode. Possible modes are:
Enabled: Enable UPnP mode operation.
Disabled: Disable UPnP mode operation.
When the mode is enabled, two ACEs are added automatically to trap UPNP related packets
to CPU. The ACEs are automatically removed when the mode is disabled. .
TTL
The TTL value is used by UPnP to send SSDP advertisement messages. Valid values are in the
range 1 to 255.
Advertising Duration
The duration, carried in SSDP packets, is used to inform a control point or control points
how often it or they should receive an SSDP advertisement message from this switch. If a
control point does not receive any message within the duration, it will think that the switch
no longer exists. Due to the unreliable nature of UDP, in the standard it is recommended
that such refreshing of advertisements to be done at less than one-half of the advertising
duration. In the implementation, the switch sends SSDP messages periodically at the interval
one-half of the advertising duration minus 30 seconds. Valid values are in the range 100 to
86400.
