by the way, I found this one of good ways to check network performance to a certain application.

Thanks Brash. SD-WAN & Traffic shaping > Uplink statistics , I changed from default which was 8.8.8.8 to a SAP cloud application (I am in Thailand and SAP app is in Sydney), and the Uplink statistic now shows that my Internet1 has a lot of hiccups reaching SAP app.

How does MX report its RTT Latency and Jitter report in MX Summary (Organization > Summary Report) Does MX measures RTT, Latency based on real traffic which goes through each WAN ? or it measures against the IP destination that we configure in SD-WAN & Traffic shaping > Uplink statistics ? Thanks, Sakul

In the Meraki Mesh document (as of Oct 3,2023 update), it said that the New Mesh Features in MR 29.1+ Firmware supports AP Mesh over 6GHz on new Wifi6E AP (for example MR57). I understand If we use 6GHz for Mesh backhaul, that means we free up 2.4GHz and 5GHz to serve to clients only, which should be a good thing in term of RF Management. But I try to search information on how much this will improve in term of clients throughput and latency. Have anyone done any test on the Mesh throughput when using 6GHz as a backhaul? Does it provide much better Mesh throughput for client devices? Assuming that most of the clients are still 2.4GHz/5GHz devices. Thanks, Sakul

I end up keeping this 'Policy-NAT VPN' with Cisco ASA, and move everything else to Meraki MX Thanks everyone for the suggestion.

Thanks Karstenl, but the client has already bought the MX with 5 year Adv Sec license 🙂 In fact, the client has been moving to Meraki Full stack, last year they replaced old Switch and AP to Meraki MS, and MR. and this last piece to replace is the MX. So, I just want to confirm that MX is incapable of doing this 'S2S VPN another WAN IP NAT'? by the way, is there a specific term we call this kind of NAT? Thanks again,

My client is a supplier for a large US automaker. The automaker requires every suppliers to crate a S2S VPN for its auto sequencing process. Currently my client uses Cisco ASA, and the setup goes like this. Now, I am replacing the ASA5505 with Meraki MX75, but I cannot find a way to do the S2S VPN NAT on the Meraki. I have tried the ‘Site to Site VPN Translation’ https://documentation.meraki.com/MX/Site-to-site_VPN/Using_Site-to-site_VPN_Translation, but when I tried to translate 210.1.xx.48/28 to 192.168.200.51, it gives me the ‘overlapping VPN subnet ’error. And I think this ‘Site to Site VPN Translation’ does not serve my purpose because the MX will translate all the WAN subnet (I need to only translate one IP). Can anyone shed me some light? Thanks,

Just want to check if now (May 2021) Meraki has plan to add this DOM feature in to the SFP/SFP+ ports?

Today Meraki MS120 shows connectivity problem "Disable switch (bad IP assignment) MM-DD HH:MM:SS)" However, this error message is not found in the Event Log. I wonder why Meraki does not capture this in the Event Log. I also found that Meraki Event Log is quite limited compared to Cisco classic world.

@Bruce @PhilipDAth @GIdenJoe I am very sorry. It was my typo. I meant X550-AT2 (10GBase-T). Your inputs are very helpful. Thanks again all and the community.

MS350-24X has eight of mGig RJ45 ports. On the Server side is Intel X550-AT2 (10Base-T) NIC. My customer worries that since mGig is Cisco proprietary protocol, will it be compatible with standard 10Base-T ? On the Intel X550-AT2, I can search for information easily, it supports 802.3an, 802.3az, P802.3bz/D1.1 But I cannot find such information from Meraki side... whether Meraki mGig support 802.3an, az ... ?

Hi PhilipDAth, in this case I did not do the "RTLS" style.. rather I did "Presence Detection" style. where I have AP1 in hallway and AP2 is meeting room 30 meters away and the Tag is located around the middle of the two APs. As I observed, the "NearestApMac" is more accurate in pointing me the location of the tag. So, I wonder what does "Last Seen By" mean exactly?

Meraki launched BLE version 3 in late 2020. This BLE v3 API introduces a new property "nearestApMac" which tells that tag is nearest to that AP. Also in the Dashboard>Wireless>Monitor>Bluetooth Clients shows you the list of tags with "Last seen by" AP. I found many time the "nearestAPMac" and "Last seen by" are different APs. For example, for the same BLE Tag, API tells you "nearestApMac" is AP1, but Dashboard tells you "Last Seen By" AP2 I wonder if Meraki uses different algorithm to determine these 2 values differently ? note: AP1 and AP2 are in adjacent areas.

The good news is that Meraki BLE API version3 can now produce LAA tags. I just tested and saw it (LAA BLE tag) posted via the API.

Hi @littleboots I created a support ticket, first the support told me to call local Meraki telephone number. But I insisted that he escalate this case to Meraki Dev team. I also create a "make a wish" request for allowing Scanning API for BLE with LAA. Hi @colinster In my case, I am developing Asset Tracking for my customer's warehouse. I plan to deploy about 50 of BLE Tags attached to their pallets. So far, i bought 20 BLE Tags but Meraki API allow me to see only half of them. Thanks.

Hi Littlebots... Stay Safe... I will also open a case for this. I still have the Tags (both visible and non-visible) with me so Meraki engineer can check from my Dashboard anytime.

Hi littleboots, Super.... How could you figure this out ? I checked my Tags and concur your finding. Only the Tags with "0" on 7th bit show on Scanning API. Have you openned a helpdesk ticket with Meraki, btw ?

I have same issue. I have 15 of BLE tags (Brand: Kontakt, all tags are same model, same firmware level). Dashboard > Wireless > Monitor > Bluetooth Clients can see all 15 tags correctly. But Scanning API only POST out 8 tags. So, now I buy 4 more BLE tags from different brand (Brand: AprilBeacon). Only 2 BLE tags get POST from API. As a result, i bought a total of 19 BLE tags, and only 10 tags can work with Scanning API...I am scratching my head.

ha ha ha, actually what i want to achieve is warehouse asset tracking. I plan to buy beacons (from Kontakt or Estimote). And since this script gives me "bluetooth clients" data, I wonder once I have beacons .. will the beacon data show here as well?

and after the "version" is correct. POST data starts to flow to my console.. So I think all my problems are now solved.

Yes, PhilipDAth... Meraki API is sending version "2.1" so I changed the Python script (line 43) to "2.1", and now I have POST / 200 OK status... Thanks again!

Thanks PhilipDAth.. You pointed me to the right Python script. Now I can see POST data coming to my Flask... 😊 But there is still some error as the POST data is printed only when I hit Ctrl-C (breaking the Python script). Sure, there is something in the script I need to adjust to fix this problem. (as I am new to Python, i need to study more). I will update again once I got it fixed. btw, here is the POST data I got..

Hi, I am building a API for MR33 AP. I follow the https://developer.cisco.com/meraki/ 's Location Services steps. 1. In my PC, use sample Meraki Python script, import Flask, run API server => successful 2. In my PC, run ngrok http 5000 => successful 3. In Meraki Dashboard, Enable Scanning API, Got Validator key, Enter Validation key into step1, Enter Post URL from ngrok in Step2, run "Validate" button => Validated successfully 4.In my PC, Flask showed "200 OK" and Python program was waiting for POST data to come... However, there was no data from Meraki Dashboard coming. So, I checked at Meraki Dashboard, I saw the Post URLs status is red, and scanning message said "HTTP 404 : Host is dropping Scanning API POSTs" What has i missed, please anyone advise? Thanks, Sakul p.s. I noticed that in the Meraki Dashboard > Location and scanning > Post URL, there is a "Secret" field. However, in your https://developer.cisco.com/meraki/ Location Services, I do not see any line verifying the "secret" key in the Python sample script. Is that the case ?

First, look at Addressing & VLANs, make sure that the MX is in "routed" mode, and the LAN IP rang is set to 192.168.1.0/24 . By default MX device has DHCP enable that why your direct connect laptop can access Internet. But the default IP that MX is giving you can be different than what you have in your LAN.
