2-20 UPnP

UPnP is an acronym for Universal Plug and Play. The goals of UPnP are to allow devices to

communications, and entertainment) and in corporate environments for simplified installation
of computer components

Figure 2-20: 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.
