Hello,
We are running into issues where IAPs that were installed years ago were never properly joined to the working cluster so they were never upgraded. This is causing major problems after recent network refreshes that are putting those old IAP into the correct VLAN, which is allowing them to try and join the cluster.
I am parsing through the syslog data for one of the clusters and I see this trap. Not sure if this is the smoking gun I need to use to ID other clusters that may have this issue as well.
SNMP Trap Category is Hardware or SNMP Trap Category is Software (Normal) System Alert
