UPNP
Configure UPnP on this page.
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.
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 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.
