GS110T/GS110TP Multicast overload bug
Hi, I have the following switches on a network, and they all suffer from this issue: 2x GS110T (v5.4.0.6 - latest?) 2x GS110TP (v5.4.2.30 - latest?) 1x GS110TP (v5.0.5.4) 1x GS110TP (v5.4.2.13) 1x GS110TP (v5.4.2.18) I am using them with a piece of software (Sennheiser WSM) which monitors Radio Mics over broadcast. As soon as this traffic starts the following occours: All switches either do not repond to most pings (70%+ loss), and when they do they have a very high reponse time (average 600ms+) the web interfaces on all switches fails to respond, and any open sessions stop functioning until the traffic is stopped. The traffic continues to pass, and reaches all the PC's ok, it just makes it impossible to monitor the switches, or configure them for anything else. My *guess* is that there is something in the packets that the switch cannot understand, and so the internal CPU is getting maxed out while trying to read it. I have tried with IGMP snooping on and off but there is no difference. I have saved a 25 second wire shark capture. http://jasmine.19inch.net/~james/wireshark/Wireshark-GS110TP-issues2-filtered.pcapng When it is started I am pinging one of the switches (PC IP: 192.168.99.41, Switch IP: 192.168.99.210), which continues all the way through. At 12 seconds I enabled the switch ports with the radio equipment attached. at 12.1 and 12.2 seconds the broadcast traffic from the equipment starts at 13.6 seconds there is the first ping request without a response. For the rest of the capture the ping responses are either very slow, or non-existant Does anyone have any ideas of what I can do to stop the switches overloading, or at least minimize the effect?
