@panzerscope, Thanks for your feedback, since you have also raised the eITS ticket, and based on the log I can see that your transceiver is in the high operating temperature therefore it will trigger the "SFP detect" once it has been triggered then the fan speed will keep in the high RPM in order to cool down the…

@Lee201028, Could you let me know which model you use?

@Hoygen83, May I know if the issue still persists? Based on the logs, there is a topology change occurs, more likely there is a ring topology in the environment which may cause a loop if there is a misconfiguration. The easy way is to check the SW port LED in the front panel and see if a port is blinking fast. Or you may…

@n5hzr, Does the firmware 2.70 patch 0 or patch 1? I have tried to reproduce this issue with firmware version 2.70 unfortunately, I did not see the issue, can you provide the specific step that I can try to follow. On the other hand, please collect the tech support file and private message me.

@white782, It's already in our roadmap and also the candidate for a release. :)

@businessuer, Many thanks for your input, will improve this part and make it more smooth in the future. :)

@Jurgen_lucca, It's been a while not hearing from you, there is one thing I'd like to confirm with you, when you mention about "the speed rate is too variable and is set to 20 - 30 MBit" does that means the speed drops down to 30Mbps or it's like if the speed limit was 100 and you only get 70~80 Mbps?

@businessuer The current design needs to activate firmware status then the front-end (browser) can get the device's relevant information and the browser can know if this device is available to do the firmware upgrade. It's not a bug 

@businessuer, Please check the firmware status column first then can use the upgrade feature. :)

@bandchef, Glad to know your issue has been resolved, you do not need additional settings, because IGMP snooping is the feature that only forwards the multicast packet to the port which need to watch the channel. :)

@LIN,感謝您的回覆，想知道這些client (包含PC與IP phone)是使用DHCP或是static IP? 因為根據您的描述也有可能是因為有IP conflict，某些設備的IP衝同導致這個問題。 另外可以提供GS1200與GS2210的configure檔給我們嗎，謝謝

@LIN, 我們在本地端無法複製出問題，想請問pinginfoView的結果是會掉多少封包? (有幾%會遺失)，能讓我們知道一下結果。 另外想請問一下是否連ping GS1200的mgm (192.168.10.168) 相同VLAN也會掉包嗎?

@bandchef, May I know if your ethernet symptom is the networking disconnected? If it is the case, could you please help activate IGMP snooping (there is the quick link on the home page) and set "Unknown Multicast frame" to drop, should improve the issue.

@rickyu, Believe that are the clients you have blocked via client page, on the right corner where you can add the "Policy" checkbox then will show up. For your second question, since in the current stage APP cannot hide those clients, for now, please use sorted as status.

@Jurgen_lucca, This is a known issue on GS1900 series for gaps on TCP traffic ingress rate limit performance. Zyxel has made effort to improve accuracy of ingress rate limit performance on business Switch GS2220 series and above as this is more frequently used as an advanced requirement for business network. For product…
