Object 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.
• 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 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.
