I recently had an entire hive pop a major orange alarm (nearly every AP had the same alarm): "Default DTLS passphrase is in use. Push a complete config to update the passphrase automatically, or set it manually and push a complete or delta config. " The alarm eventually cleared, but I was advised by someone internal that this was caused by my monitoring auto refresh rate being set to five seconds rather than a larger amount of time. Is that true? I can't repeat it, and I haven't found any evidence on the Googles to back that claim up. There are about 500 APs in the hive.
