[XS1930-12HP] CARP MAC gets falsely marked as static

Unable to find IP management - GS1920-24HP
Hello, I have an old GS1920-24HP that works flawlessly, but I want to implement VLANs on my network and I can't find the management IP address of the switch. I've tried Zyxel One Network Utility (ZON), but it doesn't find anything on the network. Could this switch to be older version that is NOT managed? Google (and AI…

GS1200 Management VID DHCP-IP on tagged VLAN.
Hi, I am pleased to see some basic managed switched now supporting Management VID. However the GS1200-5 (v1) that I picked up to test, seems the DHCP client does not operate on the tagged VLAN that is set for the Management VID. Is this known behaviour? I don't want to set a PVID and untagged for the management VLAN. I…

GS1920-8HP V5.00(ABKZ.2) - LACP NOT working

GS1900 - Enable Port PoE not working with v2.9
Hi, I've just upgraded the firmware of my GS1900-8HP switch vom v2.0 to v2.9. After upgrading, the OID “.1.3.6.1.2.1.105.1.1.1.3.1.x” for PoE enabling/disabling does not work anymore. SNMP Clients report that there is no such variable name in the MIB. With v2.0 this worked. Did the OID change? Cheers michiba

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…

Brand new XGS1250-12. Seems it may be dropping 10G port randomly
The switch is on a shelf so plenty of circulating air and ambient is ~70 fahrenheit. So far I've had it for about 3 days and had 3 drops. It's connected to my router (running opnsense with a Chelsio T540-BT) which had been working fine by itself as a software switch for months. I see the NIC card that connects from…

XS 1930-12HP link speed settings in aggregation mode missing (Nebula Cloud Interface)
I want to create an aggregated link between my GS1900-24 and the XS1930-12HP with 2 DAC cables on the SFP ports. If I configure the individual SFP+ ports and set the link speed on the XS1930 to 1G (because GS1900 only supports SFP = 1 G) then the links work fine. When I then aggregate the two ports the link setting is…

We're experiencing instabilities around clients that authenticate with 802.1x doesn't get redirected to the correct VLAN. A cable disconnect/connect or reboot may help. On a Windows client these commands helped: netsh lan reconnectipconfig /releaseipconfig /renew. Any tips to improve this?

Configuring a Voice VLAN on GS1915 8/24 EP Switch
Reading the User Guide (UG) [Version 4.70 Edition 5, 12/2024] and online posts for Voice VLAN is causing some confusion. The configuration of OUI is straight forward but what is required beforehand is not, [at present] I have a Peplink Router with networks 1.1 and 10.1, the GS1915 switch configured for 2 VLANs (1 & 10) all…

However, when I set port 28 as PVID on VLAN 1 (managed by my firewall) and as trunk, with a fixed no-tagging for port 28 on VLAN 1 and a…

Where is a manual and other documents like Declaration of Conformity, for EOL product?
A crystal void now appears at this address: https://www.zyxel.com/ua/uk-ua/support/download?model=xgs2210-52hp Is this a sign that the company is ashamed of its engineers' old work and acknowledges the worthlessness of such information?
