We detected most of our AP with Flagged status. This status happened randomly with random APs. The Flagged type is AP health high connection failure flag. Code 330. Do anyone has any idea why this issue can occurred and how to solve it.
FYI, I was told the same, that the new firmware will fix the problem. I upgraded my vSZ and APs to 184.108.40.206.624. There was no change. I still have over half my APs in flagged status, despite having a very low number of devices compared to normal.
Just closing the loop on this one... got a final explanation for this on my case. Looks like Ruckus considers this new behavior a feature 😕
"As [redacted] mentioned, In 3.6 we
introduced a new feature where the AP would calculate all types of client
connection failures and report it to SZ. That's where you see a huge difference
between 3.5 and 3.6. The AP would take into account Auth, Assoc, EAP, RADIUS
and DHCP into account for reporting connection failures. In 3.5 AP didn't have
even 50% of this ability.
In 3.5, SZ maintains the
connection failure history for up to 1 week, AP reports failures in multiple
counters to the controller. In 3.6.2 it is changed to use a different counter
that was delta.
Please refer 3.6.2 Release
Resolved an issue where the controller kept a track of old client connection
data, which resulted in incorrect display of client connection failures.
To understand these failures,
you can select an AP where you are seeing high failures and go to health tab
for that AP. Under the health tab you have two sections, one for performance
and the other for client connection failures. If you go to client connection
failures you will have complete plots showing under which above category are
the failures happening. Now if necessary you can choose failure types as show
below and also click on individual failure type to see which clients are failing.
This feature was introduced to help customer debug his network issues."
