F0615-O
Known Restriction or Limitation
I.D
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™. 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 servers 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 return 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
Docker requires exclusive use of subnet 172.17.0.0/24 for containers. Customers
should not use an IP address in that range for any VLAN or network interface.
ECA-532
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.
ECA-1484
Interaction with ExtremeManagement Center – Management of Extreme Campus
Controller by ExtremeManagement Center will be enhanced over time with the
roadmap. ExtremeManagement Center v8.5.2 is the minimum release base for
integration. Version 8.5.2 provides recognition of an Extreme Campus Controller and
representation of Wireless Clients and managed Access Points included in the
Wireless tab.
Additional integration will be delivered in upcoming releases. ExtremeManagement
Center 8.5.2 is the current recommended minimum release.
Info
Several old Intel clients (i.e., Intel dual band Wireless AC – 7260) if they are using old
drivers are NOT seeing BSSID / SSID advertising 11x capability. This is a client issue
(forward compatibility). Other older clients may have this issue.
