Ports Flapping/Resetting
Region : UnitedStates
Model : TL-SG3210
Hardware Version : V2
Firmware Version : 1.9.8 Build 20140818
ISP : Comcast
Greetings All,
I recently purchased two 3210's for my home. They are connected together via a standard CAT6 cable, Switch 2 (SW2) Port 1 uplinks to Switch 1 (SW1) Port 8; and then SW1 Port 1 uplinks to my Sophos UTM router.
I have attached a basic ASCII drawing:
Network.txt
I haven't delved into anything really exotic yet as I am trying to figure out how they will handle performance wise, and so far, I'm completely dumbfounded. The Port 1 of SW 1 keeps resetting itself. It might be 10 minutes, it might be an hour, it's not happening on a standard interval. Unfortunately, however, it's causing the entire network to lose connection to the UTM and therefore the internet.
I've tried setting the interfaces statically to 1000MFD on both the inside of the UTM and SW1 Port 1, this did not help. I have tried enabling Flow Control on SW 1 Port 1, no change. At this point, I'm worried there is something wrong with the switch, but I was wanting to check here before I looked into returning it.
Would anyone have any suggestions as to what the issue may be? Also, is there a way to turn on more verbose logging to determine why this is happening?
