My customer recently deployed WLCs and WCS in their environment. However, recently they experienced slow performance. To futher finding out the root cause, I generated the 802.11 counters report from the WCS and noticed the following parameters is shown.
Tx/Rx Fragment Count/Sec and FCS Error Count/Sec
1. Can I make the assumptions that the overall transfer of packet rate in that interval is the Total of Tx/Rx Fragment Count/Sec and FCS Error Count/Sec?
2. If the output rate of Tx/Rx Fragment Count/Sec and FCS Error Count/Sec are the same, does it mean that 50% of the packet are corrupted and this high FCA Error Count/Sec will cause performance degradation to the wireless througphput?
3. What is the baseline of the FCS Error Count/Sec that is acceptable? As for the case with wired, 1% error rate is acceptable. Will wireless have the same baseline?
