22 UpnP
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 3-23.1: The UPnP Configuration
These parameters are displayed on the UPnP Configuration page:
Mode:
Indicates the UPnP operation mode. Possible modes are:
Enabled:
Enables UPnP mode operation.
Disabled:
Disables 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 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 assumes that the switch no longer exists. Due to the
unreliable nature of UDP, it is standardly recommended that a refreshment of
advertisements should 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.
