Bug搬运工-CSCve57121--Cisco 2800, 3800 and 1560 series APs fail to pass traffic

Cisco 2800, 3800 and 1560 series APs fail to pass traffic
CSCve57121
Description
Symptom:
A wireless client automatically associates, but after a few seconds, it is no longer able to ping its default gateway.

If, at that time, the following output from the AP CLI is examined:

1. show controllers dot11Radio 0 client
2. show controllers dot11Radio 1 client
2. show controllers nss status

The client MAC address is present in the "show controllers dot11 0[ or 1] client"output and NOT present in "show controllers nss status" - this is the footprint of this bug.

Conditions:
Problem is seen on 2800/3800/1560 series access points, not on IOS APs nor on other AP-COS AP models (1800, 1540 series.)

Problem is seen regardless of client type.

Workaround:
Have the client reassociate to the SSID.

Further Problem Description:
Although this fix CSCve57121 is committed to 8.3.140.0, the symptoms described in this bug DO NOT actually affect any 8.3 release.
