The following caveats have not been resolved for firmware version 11.42T:
•
CSCdx03420—Radio might shut down when downgrading firmware.
When you downgrade access point firmware, the unit’s radio might shut down. Workaround: Select
yes for the Require use of Radio Firmware X.XX setting on the AP/Root Radio Advanced page and
follow the firmware downgrade steps again.

CSCdx07970—Cannot restore defaults on the CLI’s Ethernet Protocol Filters and Root Radio
Protocol Filters pages.
Protocol Filters pages.
The Restore Defaults feature does not work on the CLI’s Ethernet Protocol Filters and Root Radio
Protocol Filters. Workaround: Use the web-browser interface to restore defaults on the Ethernet
Protocol Filters and Root Radio Protocol Filters pages.

Protocol Filters and Root Radio Protocol Filters pages.

CSCdx11703—Hot standby packets can flood the network.
Each time a standby access point checks the status of the access point it is monitoring, it sends 11
probe packets. If you have several access points on your network set up for hot standby, the probe
packets can overload your network. Workaround: Enter a higher value for the Polling Frequency
setting on the Hot Standby page. For example, instead of polling the monitored access point every
few seconds, enter 600 in the Polling Frequency entry field to poll the monitored access point every
ten minutes.

If the radio is disabled on the monitored access point when you set up the standby access point, the
standby access point reports an initialization failure and must be rebooted. Workaround: Make sure
the monitored access point’s radio is working when you set up the standby access point.

•
CSCdw16742—Broadcast key rotation does not work with repeater access points.
When broadcast key rotation is enabled on a repeater access point that is authenticated to the
network using LEAP, data cannot be passed between the repeater and the root access point.
Workaround: Do not use broadcast key rotation on a repeater access point.

Workaround: Do not use broadcast key rotation on a repeater access point.
•
CSCdx19068—Unlimited LEAP logins configuration on ACS server can lock out roamed clients.
When the ACS server’s session policy is configured for other than unlimited simultaneous LEAP
logins and a LEAP-enabled client device roams away from the access point long enough for a STOP
record to appear in the Radius Accounting log, the client cannot reauthenticate until it is purged
from the list of logged-in users on the ACS server. Workaround: Set the server’s IETF (028) idle
timeout attribute to a low value so the server ends the roamed client’s session and the client can start
a new session when it returns.

CSCdx19118—The access point reboots when more than 23 workgroup bridges are associated to it
and you change one of these settings:

–
SSID on the Express Setup or AP/Root Radio Hardware pages
–
Classify Workgroup Bridges as Network Infrastructure on the AP/Root Radio Advanced page
–
Requested Status on the AP/Root Radio Advanced page from Up to Down and back to Up
•
CSCdx19270—When the Classify Workgroup Bridges as Network Infrastructure setting is set to yes
on an access point with more than 23 workgroup bridges associated, the access point reboots when
the workgroup bridges send small amounts of data. Workaround: Reduce the number of workgroup
bridges associated to the access point, or change the Classify Workgroup Bridges as Network
Infrastructure setting to no.
