Hi @SmileitsMe, My mistake. "lldp med topology-change-notification" is to send notification if local has topology change. Please disable "lldp notification" then the syslog will not print "LLDP Remote topologyChange" when receive topology-change-notification LLDP from other devices.

Hi @smalinowski, Thanks for your feedback. To investigate if the switch sent the RADIUS packets, please help to collect the packets by port mirror function. The screenshot below shows the steps to set the port mirror: Please connect a PC to the monitor port and open the Wireshark to collect the packets. You may set the…

Hi @akeix, if I do a reset via the button (or ON/OFF), everything works for a while then nothing again. Does this mean you can do the tests below after rebooting the switch? Ping to the switch. Access the local GUI Find the switch on ZON tool. In addition, please check the network adapter is correct if you cannot find the…

Hi @smalinowski, The model I used is GS1900-8. So, I think I'm the correct one. We're using a similar configuration, but the results are different. This means the authentication process wasn't triggered on your test. This could be because: The PC didn't enable authentication. The PC connected to an 802.1X disable port. The…

Hi @JesJen, Please press the restore button to reset to factory default. The screenshot below is the guide on the restore & reset button. Here's the User's Guide for the XGS1930 series switch for you to reference: https://download.zyxel.com/XGS1930-52HP/user_guide/XGS1930-52HP_V4.70_Ed2.pdf

Hi @smalinowski, My configuration is below, which is similar with yours, and my GS1900 will send Radius request to the Radius server. The packets when I connect a laptop to port 2 of my GS1900: Would you like to share your topology when you were testing the port authentication?

Hi @ilario, Thanks for the details. Based on the size of your home, accessories might not suit this scenario. It is recommended to purchase additional access points to extend the wifi coverage. You may find them on our website: In addition, you may use wireless roaming to allow your wifi client's connection won't be…

Hi @FrankLauer, Thanks for the configuration file. After checking, I found there's no policy that blocks access to device and ping. Since you mentioned you reset the NXC2500, could you help to isolate the NXC2500, only connect a PC to the NXC2500, and access it again? I would like to clarify if there was an IP conflit.

Hi @SmileitsMe, Thanks for the tech support file. The reason for printing the log "interface: LLDP Remote topologyChange" is that you have enabled "lldp med topology-change-notification" on all of the ports. May I know if you need this feature enabled in this network? Could you disable it temporarily? Since the log…

Hi @otello1, 1. The first strange thing is that the switch of the stack is not pingable anymore nor reachable via Graphical interfaces. The new primary does'nt have to be reachable? How we have to configure the switch from now if the 4° switch is dead or permanently removed from the stack (i.e. it is broken) ? This could…

Hi Usually, a network engineer plans VLANs/subnets before building the network. So, this idea is quite new to me. Would you like to share where did you find this feature?
