Our phones (Mitel) have an issue with interacting with Meraki switches. I changed out the Merakis with old Dell POE switches that have been factory reset. Have experienced no issues since. So overall, it could be that the phones expect a certain wattage/signal from the switches and they either get bottlenecked or they get some kind of kill signal. Either way, never could find the actual answer from either Mitel or Meraki.

I can't think of a better example of digital transformation than switching from paper charts to an EHR system Moving 150,000 patient's records from paper is no small task. This upgrade goes far beyond changing from pen and paper to computers because this is years and years (and years) of files that must be digitized. This task was not a fun one but we no longer have to search warehouses of records to find the right charts. I can only imagine what kind of ingenuity went into making a place like a Amazon warehouse, that's a whole nother ball game.

After talking with our provider, Mitel, it was suggested that there is an issue where if there is a port scanner that is multi-casting, such as IGMP, turned on then the phones with perceive this as an error. They will reboot to regain the signal. Look at your port packets in the dashboard. Multicast/Broadcast messages on ours are above 10 million a day. Just one suggest of many suggestions we have gotten to fight this thing.

Did them simultaneously to minimize disruption to the end user. Changing the VLAN on the switch will cut the connection to the device momentarily. We are still in testing with this and have found it won't work on daisy chained device (Phone > Computer). You can still change the device's settings without affecting anything else, just don't change the switch.

Another change we made was changed we have made is in the port configuration, we removed the Voice VLAN setting. Before this change, our POE devices were running at about 2.7W. After the change, they are up to 4W. This seems to have been restricting the proper amount of wattage from getting to the POE devices.

So far, what seems to be working is that we have turned off LLDP on the devices. Our POE phones had LLDP turned on and the switch also has LLDP turned on. It's causing a wattage conflict and it reboots the phones. We are letting the switch handle all LLDP request and so far so good. Hopefully, this is the fix! fingers crossed

Right now, the only thing we have been able to figure out is that our POE phones have LLDP turned on and the switches also have LLDP turned on. This could possibly cause a mismatch and make the devices reboot. Really digging deep for this one.

No resolution to the case as of yet. The port STP changes are still occuring. It's fine with the PCs on the switches but it's killing our POE devices.

Thanks, I'll add that to my case and hopefully it will be resolved

Same issue on 2 MS220/2 MS225. Contacted support and they haven't seen anything like it before. Updated to 10.45, checked power supplies, isolated ports, disabled CDP/LLDP, all at the request of Meraki. Still occuring on all POE devices. At least I know I'm not the only one.

Yes, They only run 30-50W/740W on all of them. I'm adding in some power injectors and will rollback updates tonight to see if that makes a difference.

The ports that are giving me the most problems have ShoreTel POE phones plugged into them. It is occurring on ports with computers attached, but the NICs react quicker to port status changes.

That's what I thought at first but there are no loops. Port 22 is just an example of what's happening. If I switch ports, it starts happening on the new port also.

I'd say all of them affected. Whenever I change ports, that port begins to have problems

I've followed everyone's suggestions from this board and many others, but our ports keep changing. It affects all ports, but it really affects our POE phones since they reboot everytime. Our data is on VLAN 1 and our voice is on VLAN 3, so separating them isn't an issue. We are using MS-220s at one location and MS-225s at another. Firmware version is MS 10.45 Anyone able to assist? This goes only 24/7
