Roaming/PMK bug

Unanswered Question
Jul 30th, 2008

Does anyone know anything about CSCsl34076? I found it mentioned in the release notes for WLC code 4.2.99, but other than that it's like it doesn't exist. The description of the bug in the release notes state "Controllers cache only one PMK per client device, but they

should cache several PMKs for each client. This defect forces client

devices to reauthenticate and renew the PMK when they roam.

Workaround: None."

I think I may be experiencing that but I've been unable to find out any additional info on the bug. My clients (Symbol scanners running WPA2/PEAP) sometimes do a successful fast roam but most of the time they do another full re-auth.
