I did a reset on the…

Both of my GS1200-5 and GS1200-8's web interface stopped working completely.
Hello, While I wanted to configure both of my switches, I couldn't connect to the web interface of them. No matter what I've done (factory reset, pinging 192.168.1.1 and 192.168.1.3), the Windows machine output was "PING: transmit failed. General failure.", and my Kubuntu's terminal thrown out "Network is unreachable". How…

XGS1250-12 / 2 10G ports (9 and 10) are not working after short power cut
I have noticed that this particular switch seems to be susceptible to this kind of failure as there are a couple of posts on this forum describing my exact issue. Before the power cut only port 9 was being used on the switch. For some reason when power was restored ports 9 and 10 no longer worked. I still have access to…

Import certificate - ERROR: Import custom CA fail
Hi, I just received today an XMG1915. I configured almost everything but can't import custom certificate. We run our own CA and all our services in our lab are using certificates issued by our own CA so they are trusted by our browsers in the company because the CA-Certificate is distributed to all computers.

Zyxel XGS1935 and routing
Hello team, We have 6 Zyxel GS1915 and GS1920 switches that need to be connected to a new xgs1935-28hp. Since we will probably use static routing and since we use Traffic Inspector as our Default Gateway, do we need a real physical router on our network or xgs1935-28hp would be sufficient? Thank you.

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…

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
