Hello Experts,
I find issue "PTK Challenge Failed" issue in random clients which always complain we lost our connection.
We have MM with running version 8.10.0.6 LSR with 2 controller (Model7502) and 158 APs with same image version.
I would like to get rid of this issue, Could you please share with me your experience in this regards?
is disabling OKC and Prohibit IP spoofing can help ?
I used these commands but still did not find answer:
show ap client trail-info
show ap debug radio-stats ap-name xxxx radio 0 advanced
show auth-tracebuf mac
show ap debug client-table ap-name xxxx
show ap debug client-deauth-reason-counters
