Use the following information to troubleshoot the startup process for a standard power (SP) 6GHz AP starting up from zero power or a cold reboot.
The SP AP powers up:
The 6GHz LPI service starts up.
ExtremeCloud IQ deletes previously reported FTM and GPS data.
APs discover the neighboring APs. They collect the FTM ranging data and upload new data to ExtremeCloud IQ.
AP with a built-in GPS module starts collecting GPS samples and uploads new data to ExtremeCloud IQ.
Geo-Location Agent:
APs - The FTM data is used to locate the APs on the floor map. The Geo-Location Agent determines their geo-locations.
Anchor APs with GPS module:
The FTM data is used to locate the anchor APs on the floor map. The Geo-Location Agent determines if the anchor AP has been moved from previous location. If the AP has been moved, then the new GPS coordinates are used to locate the AP and the agent re-aligns the map to the new coordinates.
Anchor APs set up by Mobile App:
The FTM data is used to locate the anchor APs on the map. The Geo-Location Agent determines if anchor AP was moved from previous location. If the AP has moved, then the operator is alerted to use the Mobile App and provide new geo-location coordinates for the anchor AP.
Using the updated geo-location, the AFC agent queries the AFC server and restores AFC service.
The SP AP operating with co-ordinates coming out of a soft reboot, or one with the device still powered on.
After ExtremeCloud IQ adopts the AP, then ExtremeCloud IQ restores the previous location and spectrum of the AP as the AP was not moved.
ExtremeCloud IQ Contoller – availability pair recovery
ExtremeCloud IQ Controller Upgrade, single ExtremeCloud IQ Controller boot or crash:
All AP co-ordinates are synchronized between both controllers. A seamless recovery is expected if only one of the controller reboots.
Both controllers lose power:
The AP coordinates are lost
The FTM and GPS data must be collected from scratch and all co-ordinates recalculated.
