Parameter descriptions
:
Mode
: Indicates the UPnP operation mode. Possible modes are:
on
: Enable UPnP mode operation. When the mode is enabled, two ACEs are added automatically to trap
UPNP related packets to CPU.
off
: Disable UPnP mode operation. The ACEs are automatically removed when the mode is disabled.
TTL
: Time To Live value used by UPnP to send SSDP advertisement messages. Valid values are 1 - 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, the standard recommends that such refreshing of advertisements 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 100 - 86400.
