6.1.12 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

Description
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.
