Dec 16, 2020GS108Tv3, disable SSDP broadcast on UDP port 1900
I just ainstalled a GS108Tv3 (fw "Software Version 7.0.4.8") and noticed that it is sending (floodding) SSDP broadcast on UDP port 1900. Two broadcasts every 4 seconds.
I do not want nor need this, how can I disable it?
As per the 7.0.4.8 RN this was added (after loooong fights):
- Introduced an option to enable/disable switch discovery (SSDP/UPnP) protocol
Something like there, but not near to any switch:
System -> Management -> Switch Discovery .
PS. Be aware the devices don't chatter on thier own - you must have systems on your network doing some M-SEARCH multicasts on 239.255.255.250, the reply is sent to the requsting IP as a UDP unicast packet 8-) - so the noise is not caused by the device. And no broadcasts involved by the way, too.

Found it. An option was introduced in the very latest firmware 7.0.4.8.
