Known Restrictions and Limitations:
Known Restriction or Limitation I.D
Certain wireless clients (such as Qualcomm Killer Wireless 1535 and Intel
7265D/8260/8265) have been known to not complete the 4-way handshake in
order to fulfill the association process in networks that have both PMF/MFP
(802.11w) and Fast-Transition (802.11r [FT]) enabled.
The currently recommended workaround is to not enable PMF/MFP configuration
on a service that is also using 802.11r. Such clients have been demonstrated to
work correctly on services with just 802.11r (FT) enabled.

To improve stability of mesh when SmartRF is used with a mesh root AP:
* Use fixed channel width.
* Set SmartRF sensitivity to "Low" to decrease the time that the AP will abandon
the channel for scanning.

When an infrastructure WLAN (used for connecting client bridge APs) has Quiet IE
enable, the client bridge link becomes unstable. It is a best practice to disable
Quiet IE when a WLAN is used for a client bridge connection.

XCC-1486
A reboot of the peer Extreme Campus Controller is required when Availability is
configured for the first time to ensure synchronization of the configuration of
ONBOARD attributes, such as device groups. This issue will be addressed in a
future release.
ECA-622
The switch primary/backup availability is not supported on the EXOS switches
running the 3.4.1.8 Cloud Connector. This affects the deployments where two
appliances are configured in an Availability Pair. If the primary appliance is going
down, then the EXOS switches will not send statistics to the backup appliance and
will be marked in red "Critical" state. When the primary appliance is coming up
again, the switches will resume sending statistics information to the primary
appliance and the state of the switch will be marked with a green "Running" state.
ECA-455
Allow UTF-8 characters in JSON payload for all Rest API so non-ASCII / Unicode
characters are accepted in Rest API requests to comply with current Rest API
standards.
ECA-321
MAC-based authentication and WPA3-Compatibility (SAE or WPA2-PSK) and PMF
"Required" may not work. This issue will be addressed in a future release.
