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.
