UPnP
UPnP Configuration:
Mode: Enable or disable UPnP operation.
TTL: TTL (Time to live) is used to configure how many steps an UPnP advertisement can travel before it
disappears.
Advertising Duration: This defines how often an UPnP advertisement is sent. The duration is carried in Simple
Service Discover Protocol (SSDP) packets which informs a control point how often it should receive a SSDP
advertisement message from the switch. By default, the advertising duration is set to 100 seconds. However,
due to the unreliable nature of UDP, it is recommended to set to the shorter duration since the shorter the duration,
the fresher is UPnP status.
