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?

Hi @Brianza, I am glad to see that everything is fine now. Thank you for your feedback. I will share it with our team to help us improve. If there's any problem occurring from your network, please feel free to let us know.

Dear @Brianza, Thanks for providing the detailed information to us. After investigation, we found that the order is a switch with a "priority shipping" service. You contacted the Zyxel store agent about the shipping progress on 4/16. The agent found that we were not able to fulfill an expedited delivery to their address…

Hi @lukipilot, This has some workaround without additional devices. You may: 1. Place the IOT devices (Sonos, Philips, and smart TV) within VLAN1. 2. You can create an SSID for VLAN 44. Then you can control the IoT device when connecting to this SSID. By the way, a home network normally separates private VLAN and Guest…

Hi @SmileitsMe, Could you help to collect the tech support after the issue happens for me to check? Please reference this FAQ to collect the tech support: And what is the topology of this case?

Hi @Brianza, In order to investigate your problem, could you send the email and your order ID/number via a private message for me to check? Thanks. Edit: Also the link you purchased the POE switch.

Hi @smalinowski, GS1900 does support 802.1X port authentication. And your configuration of 802.1X part is correct. I found your switch and Radius server are in different VLANs. Since you mentioned "No authorization packets are sent from switch to Radius server", could you help to check if the switch can ping to your Radius…

Hi @ilario, 250m2 seems like your home area. Could you share the approximate length and width?

Hi @FrankLauer, Thanks for your feedback. Since you can access the NXC2500 via serial cable, could you help to dump some information? Please enter these commands to dump: show version show interface all show running-config Thanks in advance.

Hi @Mkmkmk, Please reference the reply below: Can you see the current tower cell-id you are connected to right now? The Cell ID information could be found in local GUI >> System Monitor >> Cellular WAN Status >> Cell ID. Is it possible to scan for a list of towers nearby? FWA510 doesn't support this feature. Is it possible…

Hi @otello1, May I know did you set slot 1 as a force master before you start testing? 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…

Hi @lukipilot, Thanks for the details about your VLAN configuration. I searched how Sonos and Philips Hue Bridge discover their device. Based on my research, both Sonos and Philips Hue Bridge use mDNS to find the devices. However, mDNS is not a routable multicast traffic. That's why you can find the devices in the same…
