Cisco Bug: CSCta29484 - Radio stops beaconing for 10-second period
Jun 30, 2016
- Cisco Aironet 3700 Series
Known Affected Releases
12.4(10b)JDA 12.4(21a)JA1 4.2(207.0) 6.0(182.0)
Symptom: Access points may intermittently get into a state where nearby clients cannot see them. A client associated at this time will lose communications briefly, and will likely roam to a more distant AP. Then, the AP will again be visible to clients. This cycle will repeat erratically. Conditions: This is seen on the 802.11g and 802.11a radios, in 1200/1100/1310/1130/1240 APs, and where U-APSD clients are in use. This bug is seen in both CUWN and in aIOS environments (for example, this bug affects aIOS 12.4(21a)JA1.) The problem is especially prevalent in environments where the AP must frequently retry its transmission.
