I use a WMIC C3205 within a MAR3200 as workgroup bridge in a test bed environment. The other side of the radio link is made of LAP 1242AG controlled by a WLC2006. Only one AP is used for the time being and the link test results provide RSSI around -40dB.
Once the WMIC is associated, messages listed below are displayed when data traffic is started (IP camera, IP traffic generator).
When the WMIC is running the release 12.3(2)JL3, following traces are displayed once:
*Mar 1 00:19:18.873: %DOT11-4-UPLINK_DOWN: Interface Dot11Radio0, parent lost: Had to lower data rate
*Mar 1 00:19:21.950: %DOT11-4-UPLINK_ESTABLISHED: Interface Dot11Radio0, Associated To AP tdst_01_ap1 0018.74fb.e75f [None]
The link break duration is around 3s. When the WMIC is running the release 12.3(2)JL1, the same events occurred every 9s, but the link break duration is less than 200ms.
Does anybody know the source of this behaviour?
