The packet counter on the interface aren't incrementing so there's nothing happening on the port. A packet capture is empty. It's behaving in the same way a port would if connected to a media converter with link fault pass through set to off. That is, active connection to the media converter, but no connection beyond .

The only plausible explanation that I can think of is that there is a repeater/bridge in the fibre that maintains link layer connectivity on the B end, but the cabling contractor insists that it's pure end to end fibre. Unfortunately I'm in London and the kit is in Nice so I'm not in a position to verify.

Thanks for the response. Here is the port status on the B side of the connection where the port is configured as enabled: Here is the status of the A side if the connection where the port is disabled: As you can see, the B end has an active status despite the A end being disabled.

I have two MS120-24P switches equipped with 1000BASE-SX: 1.3 Gbps SFP modules on port 28, and connected to each other with MM fibre. The second switch (call it MS02) was issuing UDLD alerts on the port, but there was no UDLD alerts on port 28 of MS01, which I find strange. If one end of the connection is unidirectional it must surely be the same on the other end? There is another trunk between the two switches so I disabled port 28 on MS01, but port 28 on MS02, the partner port stays active. Why? Does disabled not mean disabled? Also, while the MS01 port was disabled, the SFP module was reseated, and I see this activity on the event log of MS02 in the form of RSTP role changes. Can anyone clarify what disabling a port actually does? My understanding is that is should be the equivalent of an admin shutdown on a Cisco switch, but the logs and port status indicate that this isn't the case.

I have enabled Netflow on Meraki MX appliances, defined the collector address and port number, and the OpManager netflow collector is recording the data. The charts I am getting however have no correlation with what is reported on the historical device data graph on the dashboard for the same time interval. The graphs are so different that it looks like they are from different appliances, where the dashboard records 90%utilisation on the interface, the netflow graph shows about 30%. Does anyone know why these graphs are so different? I can't believe the fault lies on the collector because they produce good graphs from data received from Cisco routers.

I think you're right. I just confirmed with the the remote hands support, he had the appliance connected to his home router for the initial firmware upgrade, so the 5G SIM has probably never worked. I never knew that.

Thanks for the response, I haven't raised a case with Meraki yet, I wanted to try the forum first. If 5G is unsupported, surely the SIM should fall back to 4G like it does on a phone?

Hi All, I am trying to install the above appliance with a 5G capable SIM with the help of remote hands. I have no physical access to the appliance. The appliance network was created on the dashboard, SIM was installed and the appliance was powered up. The installation was doing fine, going through the process of connecting to the dashboard, downloading the latest firmware, but after the reboot, no response from the appliance. My remote hands help was able to connect to the local setup page of the appliance an the SIM and the cellular status page reports missing SIM. I can't find any fault with the SIM, it works on a phone, and worked fine on the appliance until after firmware upgrade reboot. Reset to factory settings had no effect. Am I doing something wrong?
