If your cabling is proven then it's a config issue on one side or the other. Is the MS running a vanilla config or is it a legacy unit?  The test MR isn't going to be carrying some of the cruft that a legacy switch might - STP config, port-security, trunk settings, etc. ... View more

After spending an inordinate amount of time troubleshooting in Postman, the only way I am able to get these calls to succeed is by including both timespan and autoResolution.  The rest of the parameters seem to be optional, but without these two the returned data is always incomplete.   BTW the same holds true for dataRateHistory.     https://api.meraki.com/api/v1/networks/N_647955396387955998/wireless/dataRateHistory?timespan=3600&autoResolution=true&deviceSerial=Q2PD-VYZ9-SGKM [ { "startTs": "2020-12-23T18:00:00Z", "endTs": "2020-12-23T18:05:00Z", "averageKbps": 71670, "downloadKbps": 169932, "uploadKbps": 43779 }, { "startTs": "2020-12-23T18:05:00Z", "endTs": "2020-12-23T18:10:00Z", "averageKbps": 69428, "downloadKbps": 246332, "uploadKbps": 36540 }, etc, etc ] https://api.meraki.com/api/v1/networks/N_647955396387955998/wireless/dataRateHistory?timespan=3600&deviceSerial=Q2PD-VYZ9-SGKM [] https://api.meraki.com/api/v1/networks/N_647955396387955998/wireless/dataRateHistory?ssid=0 [ { "startTs": "2020-12-16T00:00:00Z", "endTs": "2020-12-17T00:00:00Z", "averageKbps": null, "downloadKbps": null, "uploadKbps": null }, { "startTs": "2020-12-17T00:00:00Z", "endTs": "2020-12-18T00:00:00Z", "averageKbps": null, "downloadKbps": null, "uploadKbps": null }, etc, etc ] https://api.meraki.com/api/v1/networks/N_647955396387955998/wireless/dataRateHistory?autoResolution=true [ { "startTs": "2020-12-16T19:00:00Z", "endTs": "2020-12-16T20:00:00Z", "averageKbps": null, "downloadKbps": null, "uploadKbps": null }, { "startTs": "2020-12-16T20:00:00Z", "endTs": "2020-12-16T21:00:00Z", "averageKbps": null, "downloadKbps": null, "uploadKbps": null }, etc, etc ]     ...
