Parameter
Description
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

Figure 3-22.1: The UPnP Configuration
These parameters are displayed on the UPnP configuration page:
Mode:
Indicate the UPnP operation mode. Possible modes are:
Enabled:
Enables the UPnP mode operation.
Disabled:
Disables the 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 of 1 to 255.
Advertising Duration:
The duration, carried in SSDP packets, is used to inform a
control point or control points on 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.
