Yep. It would be bad that a feature that has been in the dashboard for many years is being paywalled.

Looks nice but why did they drop the application/traffic overview from the new client view ? Is that still a roadmap thing ?

In this case it's a test setup and we control both sides but if we want to connect to 3rd parties this just looks bad. Will follow your advice and use the feedback button.

Hi all, we were able to succesfully configure a Route based tunnel between a Meraki MX and a Fortigate. BGP is working as expected the only drawback is that we cannot apply any prefix filter at the MX-side (at least we were unable to find any option related to that). This results in too many routes being shared to the firewall that is peering via the VPN tunnel. Is prefix filtering going to be added ? With kind regards, Marcel Tempelman.

Please bring back the green color. I cannot distinguish my Meraki tabs anymore. This is a real step back in end user experience. The Green color was really nice and recognizable, the new color scheme is way too boring business-like (80s IBM called, it want it's colors back).

Hi, I just thought I forgot to add this detail 🙂 Yes one of the MS250 switchstacks does the routing.

Hi, This is a FYI post. We rolled back the MS17.2.1 to MS16.9 (MS250 switch stacks) at a few customer sites because it started causing problems for devices trying to communicate outside their VLAN. Because these are care locations we were unable to do extensive troubleshooting but this is what happens: - devices (camera's and Android based communication devices) connected to the switch or via MR36H work properly after the switch came up after reboot - after a while some of these devices stopped communicating with their primary server which is outside their VLAN (in Azure, reachable via VPN). Communication with the local server in the same VLAN was fine. - resetting a device or cycling a port would restore connectivity but after approx. an half hour problems started to arise again - not all devices were affected. Rollback to 16.9 restored functionality and solved the issues. I've opened a TAC-case with this information. As an engineer I would like to investigate this more and have a real root cause but the care for the clients at these site has priority. With kind regards, Marcel Tempelman.

Hi, A few quick questions : I noticed that non-meraki VPNs now support BGP routing. In any other case (ASA, routers, etc) I would associate this with Virtual Tunnel Interfaces. - So is Meraki supporting VTI-based VPNs without calling them VTIs? - What does this BGP-routing option mean for AutoVPN ; can external routes be advertised over AutoVPN? It seems very interesting (I've been waiting for some kind of VTi-support for quite some time) but I also have many questions 🙂 with kind regards, Marcel Tempelman.

It's a bit trial and error. We have about 10 subnets on both sides. I know that Meraki uses 1 SA for all traffic selectors when using IKEv2, I'm not sure about NSX-T (documentation is scarce). We're also using Fortigates at customer sites to connect NSX-T and we see little issues there (and also with ASAs). The 3rd party VPN issues is really holding us back selling these MXs to customers and that is a shame. For one customer we installed an MX in our datacenter and AutoVPN is rock solid but that's not our preferred solution (although I would'nt mind having a stack of customer MXs in the DC). In the meantime I hope Meraki will give the 3rd party VPN some more love (and add VTI !!!!!)..

We had some differences in the traffic selectors but we fixed that. It's only the phase 2 which is flapping like hell (network instability would affect phase 1) and we do not see these issues with Fortigates.

Hello all, We have a datacenter which is built with VMWare software and for networking we use NSX-T (we migrated from NSX-V this year). VPN-tunnels with NSX-V were not really super table but since the migration VPN-issues are almost a daily occurence. We have contacted support but their standard answer is almost always "we see no issues here" Phase 1 is in general reasonably stable but phase 2 is realy a headache.

Last night I have cleaned up the traffic selectors on both sides and that seems to clear up a lot in the logging (which is not surprising) but I keep seeing these IPSec SA going up and being torn down. Troubleshooting at NSX-T can be done but has to be done at the Linux-level because VMWare does not provide any sensible tooling for that. We have support from a VMWare partner but as goes with a lot of server focused companies they have only the bare minumum knowledge about networking.... Phase 1 and Phase 2 are both the same. We run IKEv2 but we have tried IKEv1 but that is way more unstable. My question is : does anyone have any experience with VMWare NSX-T and Meraki VPN-tunnels?

Hi, when I was playing with the new AP Neighbor option I saw that AutoRF makes strange choices when it comes to channel planning: We're mostly using 40Mhz channels on 5Ghz and what I see is: - Some channels have the lower channel as primary channel, others have the upper channel as primary - AutoRF does not avoid overlap : I see often secondary channels overlapping due to this - AutoRF thinks that Channel 64/100 is also a perfect pair (have never seen this before with other vendors). Although this might technically all work fine (have had no complaints) but I'd like to see a bit more predictability ( In critical environments I opt for a static channel plan) : so no overlap and being able what to use as primary channel.

9m is just above the recommended height for the 3-D antenna. It might work but you might experience some problems at the ground level. The 3-E is more suited for that. The antenna portfolio is still the same. Must say after doing a few Cisco jobs again, Meraki has a better antenna portfolio than Cisco.... (more choice). A chat or call is no problem.

Be sure spanning-tree is working properly between the MS390 and the HP Procurve switch. A wrong config might block traffic in VLANs between the switches (MS390 runs MST (i believe) and the Procurve can run this as well (default spanning-tree is disabled on a procurve).

Hello, we have a few customers who require users to use a VPN client to access to other local VLANs also when they are at the office or workplace (so not at a remote site). Normally these users only have access to a few local resources and the Internet but with an established VPN connection they have access to more resources/VLANs. Question: Does the MX support Client VPN and/or AnyConnections from LAN-clients? It seems it does not support it with AnyConnect. If so we need to keep the old ASA up and running. With kind regards, Marcel Tempelman.

I have tried setting the power manually but even then the dashboard keeps telling me the max output power is lower than expected. I haven't done any measurement tests to see if the measured output power increases when setting it manually higher. If so the dashboard is not reporting it right but considering the explanation that this is "working as designed" I doubt there will be any difference between the dashboard and the actual output power of the AP.

I'm trying to wrap my head around this how we should consider this in a design: Let's say I design a VoWLAN network with every AP (MR46) at 14 dBm EIRP (@ 5Ghz). This means I set the AP in the dashboard at 8dBm (as far as I know that's always the AP output power without the antenna) and with the antenna gain I end up at 14dBm EIRP. Does the beam forming gain only add up when I allow more output power than 14 dBm?This could result in sticky clients. When beam forming kicks in does the output power of the AP go back to 2 dBm to compensate the 6 dBm gain to keep the max at 14 dBm? I'd like to hear Meraki explaining this because if the behavior is unclear you can end up with pretty wonky designs.

Just checking my case notes : my test on channel 100 (20mhz) saw the output power max out at 13dBm. The 3F gain is almost 11 dBm so 13+11=24 dBm which is 6 dBm below the regulatory 30 dBm. This makes sense if beamforming takes 6 dBm... (why isn't this in the datasheet ?).

I have a customer with MR46E with MA-ANT-3F antennas and it's impossible to get the output power above 6dBm on UNII-1 and UNII-2e (max EIRP 17dBm instead of the expected max 23 dBm). It allows 12 dBm on UNII-2e channels. On 2.4Ghz 3 dBm is the max output power. Support could not give me an answer (like above) why the settings are lower than the MR42E (MR42Es do not have these limitations or uses the 3dBm margin, they are 3x3:3). All in all the dashboard is a bit confusing when it comes to output power and EIRP values. Edit : customer is in ETSI region also.

I often use MA-ANT-3-E6 antennes to cover ground areas if the ceiling is above 8m (in designs). Below that I'd advise you to use a downtilt omni antenna. Main advantage of the 3-E is that you get a smaller coverage cell than with an omni so if roaming is required this will give you a more predictable wireless environment. This is a MR42E with a 3-E antennes at approx 11m in a warehouse. 3-F antennes are used for getting the signal between the racks (also mounted at 11m) and standard APs at the docks (mounted at 3m).

The Meraki example which I posted was during a MS Teams call from my iPhone 8 (started at 15:16 and took 6 minutes). The call was quite good (some glitches). The experience with the Gigaset smartphone was quite horrible but that's because it's crap hardware (sticking to APs up to -90+ dBm.......). But that aside when I look at the iPhone roaming the number do not make any sense to me. When I look at your example it seems to make sense.

Yesterday I did some testing with a Android smartphone from Gigaset. These phones are horrible when it comes to roaming. So I made a round with my iPhone 8. If I look at the timeline from a wireless troubleshooting perspective then this is a useless tool. The reporting is not consistent (sometimes the time to connect is missing) and the reported time values are nowhere near what you want to see when checking requirements. For example if you check Voice over WLAN requirements you want to see if the device roams within 150ms. Do not know who developed this but this is developed without any knowledge about wireless troubleshooting. This is useful information (Cisco Wireless Debug Analyzer):
