MS130-48P: All ports connected to APs are down

[mcoomber]

I've got 5 MS130-48P switches working within the LAN.

However yesterday, one of the switches went offline without any configuration change. This is the switch where the APs (MR44) are connected. After rebooting the switch came back online but all the APs are down. Other devices connected to the switch are on. Log shows the Port status change from designated -> disabled. 

The ports connected to the APs are Access Ports with RSTP enabled and STP guard disabled. 

When the APs are connected to the other switches they come online.

Did the switch ports show they were supplying PoE?  Did the MR44s power up?

[mcoomber]

Yes, the ports showed they were supplying PoE. They are powered up. 

[PhilipDAth]

Could you see the SSID?  Could you connect to the SSID?

When you say all the MR44s were down, what specifically was going wrong?

[mcoomber]

The SSIDs were off. 

The LED lights on the  APs were in a blinking mode. 

From the dashboard they were showing No connectivity.  

However once I changed the switch to which they were connected, the SSID was available and users could connect. 

[Nibss]

Do they work in a trunk port configuration. Are you working with SSID's on different VLANs?

Check the route bridge of your switches sounds like a potential spanning tree issue. 

Check the uplink configuration on the switch you are having issues with. 

Honestly, need to see the full topology & understand where your gateways are situated to look at this in detail. 

Can you ping the gateway the AP's are using from the switch having issues via the dashboard? Check there are no duplicate IP's on any gateway devices (I once had a Meraki access point manage to steal a gateway IP after a device rebooted and lost its lease after a power outage).

Hi Nibss,

I have attached the config of the 3850 switch to which the MS130-48P is connected. I've also attached the screenshot of the config of the Uplink port and the config for the switch.Uplink port config

Currently used config even though static settings are applied.
