GS110T/GS110TP Multicast overload bug
Hi, I have the following switches on a network, and they all suffer from this issue:

Hi DaneA,
Sorry for the delay, I had been trying to make sure that everything was stable with the updated firmwares before updating.
As you say they were able to provide an updated firmware, that appears to be working fine for the GS110TP models.
for the GS110T switches I was given a work around from Engineering, which I will post below for anyone else who has this problem:
"The root cause is, the reserved range multicast packets comes to switch CPU and the IGMP application fowards them to other ports in same VLAN. Since, the packets are coming at high rate, CPU is becoming slow and failing to open GUI connection.
On GS110T, you can try installing an ACL and drop the multicast packets in the range 224.0.0.1 to 224.0.0.255. If you need these packets, then configure ACL with redirect action (redirect the matched packets to desired port)."Cheers

Hi JMSladen,
Welcome to the community! :)
Kindly answer the questions below:
a. How is everything connected? Is the PC with the Sennheiser WSM installed directly connected to each switch? It would be best if you post a diagram of your existing network setup.
b. What is the behavior of the LED lights on the switches when the problem occurs?
Regards,
DaneA
