Occasionally our 515 or 505 WAPs will go into a problem state displaying a red LED light. In this state, clients cannot connect to them, but the on-prem Controller (7205 running 8.12.0.0) does not report them as "down". This has been the case on both the current OS and previous 8.10 and 8.7 OS.

Does anyone know if there is a way to get alerted (via email) by the controller or SNMP if a WAP goes red-light like this?

We do have SNMP monitoring in place, but it (like the controller) is currently only looking at up/down status.

Thanks,

Demetri

Have you any information as to why the AP is going into an error state? Opened a TAC case to resolve whatever error is occurring or replace the hardware if necessary?

Red Light is due to maxed cpu usage

Red LED for the system status indicates a general system error condition - not necessarily because of or exclusive to CPU usage. Data from the AP would be needed to confirm.

Well that is what is reported in Central when we experience this issue on our 615s. We have over 350 APs deployed.

We haven't experienced many instances since moving to 10.5/10.6 and collapsing our building based clusters to large singular campus groups

But it is an chain effect situation. All it takes is one AP to cause a gradual cascading effect through an entire cluster. A reboot of each AP will clear it until the next one
