XT12 ethernet port 3 yellow?

[Muyfa666]

Hi.

On the topic, I have 5x XT12 connected by Cat6 lan cables.

I still get a yellow prompt in the admin console.

I use the XT12's as switches so to speak, so I have conmnected WAN port as incoming and Lan1 as outgoing on all units.

I don't really see any slowdowns, but any idea why I get a yellow notice?

It's means that this port does not seem to communicate at full speed (i.e. 2.5 G). First step is to swap the related cable with one of the other correctly working ports then if the port remains yellow then swap the devices (if possible) since if it is not cable related that it could be either the connector on the router or the one on the other device presently connected via that port.

All cables are new Cat6 cables and as far as I can tell, the only cables are connecting modern hardware with faster than 100mbps ports.

 

[ColDen]

Are you using a network switch or any other connector/adapter/extender between the router and the other device on that port?

 

[RMerlin]

Check what device is on that port. Some devices are still limited to 100 Mbps, like VoIP ATAs or many smart TVs.

How do I know which of the units it is?

 

[ColDen]

In this case, the one connected to port 3.

Disconnect the cable to port 3 and see which device(s) on your network no longer has network/internet access.

I don't think its the condition of wiring. But it could be a mode issue along with using the 1G ports in conjunction with 2.5G back haul. The only real setting would be making sure it chooses WAN first for back haul.

This router might not have the concentration circuit on its 1G ports, so the back haul might be operating in mixed mode (both 1G and 2.5G) which I can see someone raising notice like a yellow symbol telling you its not running purely in 2.5Gb.

If you want to use a 2.5G back haul, you need to develop the 2.5G network tree properly.

To fix this, you add a managed switch to each area you have an XT12 at to break out the back haul network.

I would recommend MikroTik CSS610-8G-2S+in with two 2.5G base-t spf+ modules as the back haul tree switch servicing the 1 Gb wired net at each location.

But port 3 is Wan, and I only have Lan to Wan between the XT12's, nothing else and Cat6 cables. They are all chain connected, so if I disconnect any port 3, all units after that will loose cable connection.

Then its just the first router that needs a switch.

You can not use LAN1 and LAN2 (the 1Gb ports) while having the backhaul on the 2.5G lan (port 3) and 2.5G Wan
To service the 1 Gb devices, you use a manage switch at that location and daisy chain the 2.5Gb uplinks in the 2.5Gb back haul.

Their term back haul is another name for a spanning trunk if you are a telcom guy.

I'm a bit lost, sorry to say. Will a gigabit switch remedy this?

Do I understand correct that I cannot use the 2,5g lan port for anything, because then I will not get backhaul in the right speed?

I suspect the yellow notice may be a bug on the Network Map and not reflect reality. If you hold the mouse cursor over the yellow port 3 icon it should tell you what it thinks the link speed is.

If you then go to the AiMesh page and click on the two directly connected nodes and select the "Network" tab on the right, again it should show you the uplink speed to the router.

I use the XT12's as switches so to speak, so I have conmnected WAN port as incoming and Lan1 as outgoing on all units.

I don't understand this. LAN1 is outgoing to what? Other nodes? You appear to have two nodes connected to LAN1 and LAN2 on the router, so what's connected to the yellow LAN3 port?

 

[Muyfa666]

The lan3 is actually wan. I connect "in" to wan and "out" from lan.

Sorry, I'm not a native english speaker.

Per your image in your first post. The WAN and LAN ports.

On the ZenWiFi Pro XT12, the bottom port (2.5/1GB LAN) port (aka LAN port #3), indicated in the yellow box below, seems to be the one you are having a problem with, yes?

 

[Muyfa666]

I see. Should I NOT use the Lan3 at all if I want to have the full benefit of 1G?

You need to check the ethernet cable and the client device that is connected to that bottom 2.5G/1G LAN port. Check for any bent pins, lint, pet hair, dust, etc. that might be in either device's port. Swap the Ethernet cable connected to that bottom port as a troubleshooting test if you haven't done so already. Check that the device connected to that bottom 2.5G/1G LAN port is capable of 1G or 2.5G speed. Avoid using any power line extenders or similar connected to that bottom 2.5G/1G LAN port as a troubleshooting step. Sometimes the client network device offers the ability to adjust the duplex mode or 1G/2.5G mode on the ethernet port and possible it is stuck in half duplex mode or similar misconfigured mode causing the notice in the router's bottom 2.5G/1G LAN port.

In the end sometimes there is just a misconfiguration between devices that cause an Ethernet port to report the wrong speed. It is usually not common, but does happen from time to time.

Either cable is not good, this you can test by using another cable. Or the client connected to LAN3 is a device that run's at at 100Mbps.
In my case this is my smarttv.

So follow the cable inserted in LAN3 towards the client and check the config if the device. Maybe 100 Mbps is the max or the network config is wrong and not running at fullduplex

There are several different types of switches, but they run in two categories (managed/unmanaged) But the switch you need is 1GB to 2GB uplink with a 2Gb pass though for the trunk. You use a switch with connection concentration so it takes the 2.5G network and break it out into 1G. I run switches like this but at 10Gbase -T so I can run 1Gb devices from the 10Gb network.

Since the two SPF ports are pass through (or can be set up as pass through) it would not matter where it is inserted in the 2.5G back haul. But the way these were presented by Asus was all of them in a chain then the last output 2Gb port of the back haul was the start of the hard wire computer network. But You still need a switch like I suggested to keep everything 2.5Gb.

Will a 100mb device always cripple the speed of the whole nod?
