Link auto-negotiate not working on port 9-11 on XGS1250-12 - V2.00(ABWE.1)C0 (Februari 2025)
Hi, I have the following issue with auto-negotiate on ports 9 - 11. They always go to 100M, doesn't matter if I try it with my Realtek 2.5Gbe or Intel 1Gbe NIC, they always go to 100M on these ports. I got the 2.5Gbe NIC working when setting port 9 to 2.5G statically and statically on the PC. But after 5 minutes of working…

XGS1210-12 hangs under heavy load when using VLANs
I have a rather basic configuration: an uplink @2.5Gbps (tried 10Gbps as well; same failure) set to VLAN=10, and some local devices. One of local devices is a server, and every morning at 0545 it backs up its ~1/4 TiB drive via the uplink (VLNAN=10). This results in theswitch hanging - web ui works, I can tell it to…

XGS1210-12 can't get GUI and Switch function is weird/borked
Out of the box one of the 3 brand new switches I just bought for my classroom fails to show GUI @ 192.168.1.3 so I change it to our LAN plan. After several reset there is no way to retreive normal behaviour. What do I do ? [EDIT]. I brought it at home tonight where I have a dhcp server in my ISP router. Same issue, I can't…

Problem with 802.1X. Sometimes not working correctly and reboot needed
Hi everybody, I'm having troubles with a GS1920-48HP V2 (firmware: V4.80(abmk.1). Sometimes 802.1X service doesn't work properly. The radius server tells the switch to put a port on a vlan but the switch doesn't obey. I tried to desactivate then reactivate the 802.1X but it didn't solve the problem. After a reboot all is…

Does the XGS1250-12 have/use active cooling?
About a month ago I purchased a pair of XGS1250-12 Ethernet switches and, while there appears to be a fan port on the backs of the switches, I don't actually hear or feel them running. When I put them into service they operated at uncomfortably warm temperatures. Updating firmware from v1.00 to V2.00(ABWE.0)C0 helped a…
