Hi @Smartqwerty, But can i check this in switch web or cli? » You cannot check the jumbo frame status via web GUI or CLI since it is always enabled. And what is maximal MTU? I didnt found this in references. » XS3800 supports 12K jumbo frame for 10G and 9K jumbo frame for 2.5G.

Hi @n_j, The problem is fixed.

Hi @networkblizzard, Static MAC is used to fix the MAC address on this port and never ages out. It is normally combined with port security to ensure other devices cannot access the network via this port. When a port connects with a server or printer that is not usually moved, you can configure its MAC address as a static…

Hi @Smartqwerty, XS3800 enables jumbo-frame by default, you don't need to config it.

Hi @NEP I can access the APs (VLAN120) from my PC (VLAN1). However, like the docs mentioned above, I am unable to access the switches (VLAN120) from my PC (VLAN1). » Can you ping the switch IP address on VLAN 120 but cannot access the web GUI from your PC (VLAN1)?

Hi @jpmlore, Only on VLAN10 (a server on 192.168.10.13 can for ex. ping and have internet access) Servers on VLAN20 an VLAN30 cannot ping .1 nor internet Thanks for updating this result. This result shows that the switch configuration is correct on VLAN 10. As you mentioned before, VLAN 20 and 30 are configured as same as…

Hi @Carlo, The problem has been fixed. Please verify, thanks.

Hi @networkblizzard, Is there any way I can associate an MAC address with a specific VLAN each time it connects? » This needs the device to support MAC-based VLAN function which GS1900 does not support it. Please consider GS1915 or the above model which can fulfill your requirement.

Hi @jpmlore, So for you, nothing wrong on the switch conf (VLAN, tagged, untagged!) ? > Yes, as you mentioned you can ping each gateway 192.168.x.1 on each server. This means your configuration is correct.

Hi @westcoast, Thanks for sharing your idea. We will monitor this idea post if other community users like it. Anyone who likes this idea or has more ideas or feedback, please feel free to share.

Hi @SMRTechnik, Please check the message box. I have sent the file to you.

Hi @neukrisz, This is because the previous user still owns the used GS1920 although it does not in any organization. Please download the Nebula Mobile APP Android / iOS and scan the QR code sticker on the device to register.

In addition, the unexpected upload speed you mentioned is also the same scenario. Although the PC all way through to the ONT are 2.5 Gbps, the ONT to the Internet is 1 Gbps. This is still a low throughput scenario and will cause the client tends to send more packets. And just like I mentioned above, enabling flow control…

Hi @SMRTechnik, Please provide the model of your switch and firewall. I will provide the file to you via private message after confirming the model.

Hi @jpmlore, The switch configuration looks correct. Have these servers configured the default gateway? If not, please configure the default gateway first. If yes, but it still cannot ping the Internet, the problem could be on the router. You might need to check the router's configuration. You also can do a traceroute to…
