Thanks. We tried doing this (band steering was already disabled, but we changed all the others) It does not seem to have made any difference - certainly not better

All ports on both Meraki switches are configured as Trunk on the Native vlan. And the SSID is tagged as VLAN2. Wireless->health shows 0% fails on connection steps 0 connection problems by Client 0 connection problems by AP Less than 10ms latency on that AP, up to 11 on others Some authentication problems on several of the APs (but not from the devices we're talking about)

We use Wifi to provide networking on moving irrigation booms - 65 of them. See the attached image. We have a separate SSID and vlan for these moving devices. This system has worked dependably on a Ubiquiti wifi system, but the Ubiquiti cloud key/module has been flaky. We upgraded a portion of our system to a Meraki MR76 WiFi system using the same ssid/vlan settings, and have had mixed results. The native vlan (vlan1) has been rock solid. The irrigation vlan (vlan2) is where we're having issues. The settings are the same in Meraki as Ubiquiti as far as we can tell. On the Meraki system, we are sometimes able to ping the devices (from the server) behind a Netgear router, but are unable to ping the router or access the Web interface. Vlan 2 is entirely static IP, since all the communication from server to device is IP based. It puzzles me how we can have devices with a static IP address, and some are reachable by ping and others are not. Wait a bit, and we might be able to ping the devices that were not "pingable" a few moments ago. Any help would be greatly appreciated. Thanknks

@Nash, can you give me a steer on where to look for the per-vlan per MX network DHCP reservations? I just don't see it. My apologies. I don't see a way to cancel this, but I just found it.

Below is what it looks like now (hopefully a better drawing): That port on the core is now configured as Access, Vlan 95. Nothing else on the Core is configured for Vlan 95 (no routes, no ACLs. It just goes to the MX), But the MX is configured for V95. STP disables the redundant ports on the Cores

Thanks @ww . That did take care of it. Meraki support kept trying to find a way to make my solution work, but in the end he agreed with you. Thank you very much

This is still not solved. Been working with Meraki Tech Support, but so far nothing What works: MX Warm Spare - High Availability Pair Two WAN uplinks What doesn't work: DMZ (VLAN95) connected to both MX devices The problem, as I understand it from Meraki, is that the MX Firewalls do nothing with STP. And the MS Switches use RSTP, but do not deal with STP on a per VLAN basis. As @ww saw, as soon as I unplug the DMZ VLAN from the secondary MX, everything else works. Apparently VLAN95 connected to both MX devices completes a loop and STP shuts down VLAN1 from the Primary MX. One solution, they tell me, is to replace the WAN Breakout MS switch with a Cisco Catalyst switch which has PVST or Per VLAN Spanning Tree. This would isolate VLAN1 from VLAN95 STP wise Can anyone think of anything solutions? Thanks

Good call, @ww , when I disconnected Vlan 95 from MX2, then I could successfully plug in to VLAN1 on MX2. So why is that an issue? Shouldn't STP on the MS120 have stopped it? Or is it possible because the WebServer only had 1 IP address?

Unfortunately that was not the problem. I started out that way with just one connection to the stack from each MX. I still had to disconnect MX2 to have Internet.

I can try that tonight when most people have gone home. I'm not sure I understand your 2nd option. Vlan 95 is supposed to be a DMZ. If it is going through the stack, wouldn't that eliminate the safety of the DMZ?

The MS120 is not connected back to the LAN. It is connecting to the cloud via the ISPs, and I can manage it from the Meraki Dashboard I'm not very good at topology, so here is an attempt: The MS120 has 3 VLANs connected to it: 110, 120, and 95 The Web server has 2 NICS in it, one for VLAN95 and one for VLAN1. This VLAN1 is connected to another MS125 switch which is plugged into both core switches Each of the desktops is on VLAN1 As you can see, MX2 is not plugged into the LAN at all, because when I do, it stops our Internet. That's what I'm trying to correct. MX1 is plugged into both core switches, with STP blocking one.

We have: 2 MX100's setup in HA mode 2 ISP's 2 MS425 Switches stacked 1 MS120 switch between the ISPs and the MX100s The MS120 gives us signal from our ISPs to both MX100 (different IP addresses of course) As far as I can tell, the MX100 are working in HA mode. And both ISPs are working. On MX1 Ports 1 & 2 are connected to ISP1 and ISP2. Port 9 is connected to an onsite web server (configured as a DMZ) Ports 8 and 11 are each connected to a different one of the stacked switches. So far so good On MX2 Ports 1, 2, & 9 are the same as above. However, as soon as I try to connect port 11 to one of the stacked switches, our Internet goes down instantly. Since there is no connection at that point to the cloud, I can't capture packets from that port, can't see what is happening. As soon as I disconnect it from the stacked switch, Internet is back up. Can anyone give me a steer as to what to look for, or what I'm doing wrong? Many thanks
