We continue to see this problem on MS425's, MX100, MX250, and MS225 series switches. The MS425's are still the most problematic.

I havent noticed the links not coming back on the MS425's, but I also havent tested that scenario. If I get some time next week I will put a MS425 up in a lab and test it out to see if I can replicate your problem.

Yes, the SFP's work and will provide a link.....but the tension on the cables can also pull them out over time since they are not secured in the sfp port.

After further investigation, I believe that this is going to be a widespread issue with Meraki manufacturing. I have now tested 6 new MS425's and 6 new MX100's. They are all exhibiting the same issues with copper SFP's. The Meraki copper SFPs; (which are simply Cisco GLC-TE's in a Meraki bag) are only locking in to 84% of the ports on these devices. I am trying to push Support to figure out what is really happening, but so far I am not seeing any interest from the Meraki side in actually figuring out what has happened.

Yes, to me it looks like the metal SFP ports are a little to far back, and the SFP's can go far enough in to lock. The SFP's hit the front metal faceplate that surrounds the ports before the SFP is all the way locked in. What's strange is that it is the same way on 2 new 425's and 2 new MX100's. I hope we arent seeing the beginning of a manufacturing error that is going to be present on a large number of 425's and MX units.

@BlakeRichardson @PhilipDAth I have never had this problem before on our MS425's either; but these 2 newest MS425's sure have an issue. Waiting to see if support will do anything to get me a RMA on this gear, as we cant leave these in production with no way of holding the SFP's in the switches.

Does anyone else have any experience with MS425 core switches not being able to lock in copper SFP's? I just installed a stack of 2 MS425's, and on both switches there are multiple SFP+ ports that will not lock in a copper SFP. It looks like the Copper SFP can not be put in far enough to engage the locking mechanism. We have tried Cisco and Finisar SFP's, and I am wondering if anyone else is seeing these problems now also? It looks to me like the SFP+ ports on the MS425's may be recessed just a tiny bit too much behind the face of the switch? Also have this same problem on a pair of MX100's....but I dont really need the copper SFP ports on it.

Glad to help!! On firmware version 15.42 our SAP traffic works properly, but we found another application that was incorrectly categorized as bittorrent. Of course, you cant do the AnyConnect VPN stuff on 15.42, so you are at the mercy of Meraki support and the next version of code they release.

Not sure about the AnyConnect fixes, but 16.6 is still incorrectly categorizing SAP client traffic on my test box.

Not sure if this will help, but I have identified and opened a case with Meraki Support about our MX's that we are testing 16.4 on. 16.4 is incorrectly identifying our SAP application traffic as P2P application (bittorrent), and since I have a rule that blocks all P2P applications it is getting blocked. I wonder if some of your O365 traffic is being classified as an incorrect application and being blocked by the Layer 7 firewall rules? Do you have any Layer 7 firewall rules? If so, can you disable them and see if everything starts working? If you are dumping all the MX logs to a syslog server, you can search the syslog messages for "l7_firewall" to see if you are getting traffic blocked. I dump ours in to splunk, and it shows up like this: May 5 21:46:25 10.x.x.x 1 1620265585.486264487 XXX_FW01 l7_firewall src=10.X.X.X dst=X.X.X.X protocol=tcp sport=58700 dport=3299 decision=blocked Hope it helps.
