Caveats
Problem occurs with one access point configured as a WDS with one infrastructure access point with
WDS associated, and dot1x authentication configured on the infrastructure access point. Using the
GUI, if key management is selected an error message prints after clicking Apply. In addition, the
key management checkbox is in a disabled state after deselecting it.

CSCsr79628—Number of supported BSSIDs not shown in access point GUI.
The show controllers command report the number of BSSIDs supported, but is not shown on the
GUI.

CSCsr79832—No option available to configure guard-interval using the GUI.
Workaround: Use the
guard-interval
CLI command.
•
CSCsr81316—MALLOCFAIL and tracebacks occur in SSH process.
During normal operations, the access point’s memory becomes fragmented. The access point
eventually reloads, triggering a MALLOCFAIL and tracebacks in the system logs

CSCsr97839—1130 series access point incorrectly buffers frames destined for 7921 phone.
After some time on a call the 1130 appears to incorrectly buffer frames destined for a 7921 causing
1-way audio for the conversation. The 7921 continues to send audio and the other party can still hear
but the RTP back to the 7921 is seen hitting the access point port but not over the air. The 1130
appears to be sending QoS null packets to the 7921 thinking that the 7921 is in power save mode
and therefore buffers the frames. If the user presses a button on the 7921 when 1-way audio is
occurring, the audio works again in both directions for a few seconds then fails again reverting to
1-way audio. 7920s talking to the same access point do not experience the 1-way audio but they do
not use U-APSD.

Workaround: None other than rebooting the 7921 to start a fresh authentication with the access
point.

CSCsu11294—Ethernet driver issue.
WMIC uses f0 interface to connect to C3250 f0/0 interface (or other router Ethernet interface).
When the WMIC f0 interface is shutting down, the C3250 f0/0 interface line protocol status still
shows as up. This scenario is also seen on 1310, Releases 12.4(3G)JA, JA1, 12.4(10b)JA images.
The issue is not observed on Release 12.3(8) images.

point with WPA2/PSK configured deauthenticates and will not reassociate.
point with WPA2/PSK configured deauthenticates and will not reassociate.
The WGB associates and clients can pass traffic for about 20 minutes, after which the root access
point deauthenticates the WGB. Eventually the WGB reassociates, but could take 20 minutes or
more. Usually if the WGB radio interface is reset, the WGB can associate and begin passing traffic
again.

Workaround: Try toggling the WGB radio interface.
