Model: TL-SG116E  
Hardware Version: V1
Firmware Version: V1.2 - 20191128

Hello,

 

i have a TL-SG116E (default settings) in my Network for a while now with an IPTV Device connected to that, everything worked fine.

Now i added a second switch, same model same (default) settings.

Since its connected to the first switch with 2 cables, i have created a LAG group for the corresponding ports on each switch.

 

With the addition of the 2. Switch, my IPTV device connected to the first switch lost its internet connection. (Non-IPTV devices work fine on that port)

 

I played around with some settings and dont really get what specifically causes that. Turning off lag or IMPG Snooping on one switch fixes the issue for some reason.

Are there some special settings required when using LAG / 2 IMPG switches?
