某WLAN热点在进行瘦AP改造后，发现上网质量不如改造前，下载速率慢、网络时延高，经傲天厂家检查，表示通过以下命令可以对上网质量有明显优化，该命令主要针对有下带11n AP的AC，如果AC下带有11n AP，建议配置该命令。
config capwap-tunnel
set wifi_qos enable
set fast_fowording_qos enable
为了验证上述命令配置后对上网速率的优化效果，进行了ping网关和下载测试，命令配置前后测试进行对比。
配置前
ping网关：
Packets: Sent = 100, Received = 100, Lost = 0 (0% loss),<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
Minimum = 2ms, Maximum = 1056ms, Average = 20ms
pingDNS：
Packets: Sent = 100, Received = 100, Lost = 0 (0% loss),
Minimum = 4ms, Maximum = 2207ms, Average = 103ms
配置后
ping网关：
Packets: Sent = 100, Received = 100, Lost = 0 (0% loss),
Minimum = 2ms, Maximum = 1379ms, Average = 29ms
pingDNS：
Packets: Sent = 100, Received = 100, Lost = 0 (0% loss),
Minimum = 4ms, Maximum = 423ms, Average = 85ms
从以上的ping测试可以发现，命令配置前后，并没有明显的优化效果，以下配置前后的飞信下载测试对比，从下载测试结果来看，对下载速率是产生了非常明显的优化效果，配置后，下载平均速率提升超过100%。
以上命令在配置过程中，对用户业务没有任何影响，不需要在业务闲时才配置；建议其优化效果，建议下带11n AP的AC都进行配置。
为了确认该热点业务质量问题是否和AC上联网络或者AC有关系，在AC上配置了一个空闲端口，配置命令也比较简单，如下所示，将空闲端口eth0-3加入到热点所在的ebr3中；空闲端口 连接笔记本进行业务测试，笔记本获取的IP地址和无线侧获取的IP地址是同网段的。
config ebr 3
set ebr add interface eth0-3
exit
测试结果发现，有线侧质量非常好，测试结果如下所示，时延很稳定，下载速率达到4.02Mbyte/s
ping网关：
Packets: Sent = 100, Received = 100, Lost = 0 (0% loss),
Minimum = 0ms, Maximum = 10ms, Average = 0ms
pingDNS：
Packets: Sent = 100, Received = 100, Lost = 0 (0% loss),
Minimum = 2ms, Maximum = 3ms, Average = 2ms
