Wondering if anyone has ever seen anything like this or has any ideas what could cause this.

We have an office that has a total of 6 Meraki MS350-48 switches. They are in two stacks in two separate locations. Two switches in one stack upstairs connected to an APC UPS with an MX and some servers. The other 4 switches are in a stack in a warehouse connected to a PDU in a rack. Two CAT6 runs connect the two stacks.

Late last week we suddenly had the site go down and started troubleshooting. It turned out one of the switches in the first stack was down and simply would not even boot up - power supplies cables etc all good but switch won't even power on. We move the uplink to the other switch but it won't link up - like no link light even. The MX is on and all good - reachable, hasn't gone down etc... We notice some of the link lights on the switch seem weird - like the right half of the switch has some link lights on on ports with no cables and some ports won't link up at all. But roughly port 1-24 seem to have normal link lights so we move the uplink to port 24 and voila it links up and gets uplink. We also move the downlink that goes to the other stack to one of these ports and it also lights up. So of these two switches one is dead and one has half the ports completely failed. We even troubleshoot with Meraki on the phone and this is the result. No firmware updates or power outages seem to have occurred.

So this isn't even the end of the story - now the other stack. Similar story - the entire stack is offline - switch-1 has dead ports including the stacking ports. Switch 2 and 3 are the same. Switch 4 is offline and won't even power on. We end up replacing all 4 switches in the second stack as well to get everything back online.

Out of six switches, two are completely dead and four others have ports dead we can't get to work - even after reset. They were in two separate locations and some of them were on a UPS. We've had the occasional switch fail before but how can 6 switches all fail at the same time? Nothing else at the site seems to have had any issues.

Good Afternoon,

A Cisco rep emailed me in regards to four APs on our network, MR18s, being EoL. The rest of our APs are MR44s which are not EoL. We currently have an active agreement with Cisco.

What's stopping me from buying four new (or used but unclaimed) MR44s from eBay, removing the MR18s, and putting the MR44s in? I can get four MR44s for the price of one new Meraki AP. The MR44 serves us well in our environment and we don't have a need for anything with more capabilities at this time.

Thoughts?

I've got a client that moved to Meraki a while back.

They just purchased a bunch of C9300L coming with the cloud managed firmware. Some of these will be stacked using the C9300L stacking kit. What's interesting is the order for the stacking kits and cables actually state "MERAKI".

I've been following the documentation since Jan. for changes to Meraki cloud management for these switches and TBH, the documentation is confusing.

My questions:

1. Can I pre-provision & pre-configure the switches that will be stacked?

2. I believe standalone switches can be pre-provision & pre-configure. Am I right?

The plan is the pre-provision all the switches, pre-configure them, then once onsite assemble everything, perform any firmware updates / stacking requirements and then connect and *HOPE* the pre-configuration works.

Thanks in advanced!

Hey,

I'd like to use an MX for my homelab / home setup. I got an unclaimed MX64 at a very good price. Now I am searching for a reseller in Europe (specifically Germany if that matter).

Could you recommend any?
I contacted two different companies, but unfortunately they only sell to businesses.

I am aware of the EOL next year.

Or school is expanding to a new building they bought next door. There is a large auditorium with 20-30' ceiling. What are the best access points to use in here? And, yes I am pushing them to pay for a site survey.

Hey folks,
I was troubleshooting some wifi issues today and realized i've never actually looked into WPA3 or what the impact of moving to that would be, so glanced at some settings and noticed that there's also a WPA3 transition mode, which appears to allow clients that need WPA2 that are already hitting the wifi to keep working. I'm looking to see if anyone else has made this transition recently, and if there was any real impact or if it went pretty smoothly. We generally don't have much old gear using the wifi here, but there might be some older personal devices getting on guest wifi. Or if maybe i'm just way off base and there's no point switching from WPA2 in the first place.

Thank you!

In April I moved all 750 of my MR56 to 32.1.6. I couldn't tell you what I was at before. Since then the number of wireless issues has climbed.

I am a k-12, with most of the APs being in classrooms. 40Mhz on 5 ghz (debating on cutting back to 20mhz but I am hoping the higher bandwidth makes it more attractive). Using DFS. No band steering.

These tickets seem to be coming from areas with lower density. Using the Meraki dashboard, I can't see anything markedly bad. In one case I did have the 100% utilization on 5ghz issue, which is a known bug and swapped the AP out, with no noticeable change (other than no 100% utilization).

Changing signal strength isn't making a difference. Changing distance to the AP isn't making a difference

So my questions:

1. is anyone else seeing this?

2. I see a 32.1.7 that was released a few days ago or should I kick up to GA 32.2.3? Are the GA's generally stable?

3. Also it occurs to me that most of the people complaining have HP laptops, which is only like 6% of my deployed devices. Has anyone seen that?

4. Is there a good Meraki wireless based troubleshooting guide out there? There is a lot to the interface and while I have been doing Cisco forever, the Meraki interface seems to hide some of the indicators like re-transmits that I am used to looking for.

What is the best course Meraki ?
