Note that the signal strength on wifi doesn´t mean anything. What means everything is the SNR or Signal to Noise ratio. If you have good signal but he noise floor is high, you will still have problems. That you should check. If you live in an apartment, lower the channel width which give 3 dB better SNR every time to…

You could use spanning tree to avoid loops when creating a ring. Read about STP priority as well if you connect serveral swiches. You could also do link aggregation as suggested above to create a logical 2 GBps link out of 2 1GBps physical links. But note that you cannot aggregate the bandwidth of those links to one big…

Hi @Zyxel_Judy As I have sent the tech report I guess you can se the switch is delivering power. So to be clear… I am not using any PoE injectors. The Zyxel Switch is delivering power. And before it was my old switch with no problems for years. Now… The switch ports did not flap up and down when these messages appeared.…

Hi @Zyxel_Judy Just a note it that I cannot see any practical issues so far. And not any port flapping. All seems to work ok. But those messages worries me… A start is that you tell me what that message actually mean. Is it a software bug, is the switch about to fail even if it seems to work ok, or what? I can for sure say…

Hi This is a PoE++ Switch. So the changes you connect devices that are out of spec wont exist…. Port 6 is a class 0 device and takes 4.8W (A cisco 8 port switch), Port 7 is a class 0 device and taks 2.6W (Axis outdoor business camera M3026-VE). Just checked the power values. Totat power used on switch is 46W at the moment.…

Hi Well…No special scenario. It is just that I think it is resonable to be able to change IP:s behind the used DNS names in the IT environment. This so you can both skip the hunt to find all systems that uses the actual IP you are about to change, but also to skip login in to many systems and do reconfiguring. Ok. if you…

Yes. Now it is clear to me. It is just ZynOS that confuses me a bit. I would have expected "no lldp" on the interface level as well and not a different syntax like "lldp admin-status disabled" as it has the same meaning as "no lldp". I think disabling it on the switch and the interface would be the same syntax. I also had…

Latest firmware. I sent you config as a direct message

This happens to other Zyxel switches as well. Exit ssh from a Zyxel GS1930-12HP works ok but exits with (connected with OpenSSH client on FreeBSD): switch0.incedo.org> exit client_loop: send disconnect: Broken pipe vader@xanadu:~ # Exiting from a SSH on an ArubaOS it says (connected with OpenSSH client on FreeBSD):…

Tnx for the reply. I was a little bit confused because it was named "no lldp" on the switch level, but on the interface level the ekvivalent was "lldp admin-status disabled". But I will probably go for just receiving with "lldp admin-status rx-only" from the ISP on the fiber port :) Tnx @Zyxel_Kay

I had not yet tested a real SFP+ when posting here… Just looked for the equivalent commands in the cli and the cli PDF… Sorry for that. Now I have added one physical fiber optics and one 10GbaseT SFP+, and indeed I see the info I am looking for with the "show interfaces transceiver NN" Tnx and sorry for not trying that out…

Ok. That explains it :) Tnx för the quick reply @Zyxel_Melen
