Known Restriction or Limitation
I.D
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-1570
ExtremeCloud IQ-Site Engine 21.4.11 or Extreme Management Center 8.5.6 is the
minimum required revision for representation of Extreme Campus Controller
5.36.01 or later revisions.
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.
ECA-1961
AP310 models are not currently supported by ExtremeLocation
TM
. Do not enable
ExtremeLocation settings in the configuration Profile for an AP310 device group.
Doing so may have a negative impact on AP performance.
ECA-1620
For Extreme Campus Controller configured for authentication of administrators
over RADIUS server, the GUI responsiveness may be slow, possibly over 30
seconds if target server(s) are unavailable/unreachable at login time. If outage is
extensive, system will eventually timeout to validate against local credentials when
provisioned.
ECA-1396
For High-Availability installations, on systems configured with RADIUS Accounting
or Smart RF enabled, clients (end-systems) may experience a momentary
disconnect during the upgrade process (maintenance window).
Users immediately reconnect to the available infrastructure, so impact is negligible.
For smoother session availability with fast-failover during a failover event, it is
recommended to not run these options. This issue is being investigated and will be
addressed in a future release.
ECA-1264
Upgrade failure will occur when using special characters (escape back slash) in
topology.
ECA-466
In SmartRF mode, the AP510 power may temporarily drop to 0dBm and returns to
4dBm.
ECA-469
With on-air-busy channel conditions, it is possible for the ACS not to produce the
expected results. In this instance, perform manual channel selection.
ECA-528
Widgets do not show tooltips for lower and upper values. This issue will be
addressed in a future release.
ECA-567
Firmware for ExtremeWireless AP3900 series access points does not currently
support Smart RF. No Smart RF data is displayed.
