CHAPTER 4
WEB OPERATION & CONFIGURATION
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.
