4.2.1.9 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

appears.
The page includes the following fields:

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 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.
IP addressing mode provides two ways to determine IP address assignment:
Dynamic: Default selection for UPnP. UPnP module helps users choosing the IP address of the
switch device. It finds the first available system IP address.
Static: User specifies the IP interface VLAN for choosing the IP address of the switch device.
The index of the specific IP VLAN interface. It will only be applied when IP Addressing Mode is
static. Valid configurable values ranges from 1 to 4095. Default value is 1.
