Configure UPnP on this Page. 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. The UPnP Configuration screen in
appears.

Description
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.
The TTL value is used by UPnP to send SSDP advertisement messages.
Valid values are in the range of 1 to 255.
The duration, carried in SSDP packets, is used to inform a control point or control
points how often it or they should receive a 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.
