Hi @Zyxel_Judy I did some further tests with your advice GS1900-24 uplinked to a live LAN but only hosting test PCs itself. In all cases below, the switch MAC table looks correct, it contains all the hosts connected to the switch itself, and those from the rest of the LAN. HP and Asus pinging each other Untagged: Pings…

Apologies @Zyxel_Judy, I made a mistake with that sentence. Correction: When the GS1900-24 is isolated, the pings drop after about 1.5 hours and do not return at all. When the switch is connected to a LAN with other devices on it, then the pings drop in less than 5 minutes and also do not return at all - until I change the…

Thank you @Zyxel_Judy, I have attached before and after logs. Actually, the pings now stop well before 5 minutes. For comparison, I have an identically configured GS1900-48, running the same firmware. On here, the pings stay solid and consistent (<= 1ms) for over 1.5 hours, but, still the ping test stops and doesn't come…

To change the settings I go to the NICs' "Properties > Configure > Advanced tab > VLAN ID: Value" then simply change the value from 3 to 2 and click OK, then from 2 back to 3 and OK. It's a GS1900-24 with V2.80(AAHL.1) | 08/08/2024My configuration doesn't follow your suggested guid exactly, it uses a different VLAN numbers…

Thank you very much @Zyxel_Melen that worked, so essentially I just have to use a normal uplink and make it a member of all VLANs I wish it to pass. I was thinking I had to make that uplink a VLAN trunk.

Thank you @Zyxel_Judy - I thought I was going crazy. Is there a way to change that MAC table timeout, or it's there for safety reasons? So is it recommended to not use tagged VLAN at all, regardless of OS, if the host NIC variations are the problem? That guide is exactly what I used to set up my VLAN test lab, it's very…

Hi, I have exactly the same scenario but using a GS1900-24 and GS1900-48, configured identically and disregarding the extra 24 ports on the larger switch. Both firmware V2.80(AAHL.1). I was happy to find this post but cannot quite match up settings described here. The closest menu option I can find is Configuration > VLAN…
