4.2.7 UPnP

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

Figure 4-2-9

appears.

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.

The TTL value is used by UPnP to send SSDP advertisement messages. Valid

values are in the range of 1 to 255.

TTL

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 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.
