H3C-S5560无线控制模块信道利用率查看优化

H3C-S5560无线控制模块信道利用率查看优化

1.查看要排查无线AP的IP地址

dis wlan ap name ap01 address //“ap01”AP名称

AP name IP address MAC address

ap01172.16.1.10ac74-09d8-5960

2.开启对应AP的telnet功能

sys

[JF-S5560]probe

[JF-S5560-probe]wlan ap-executeap01exec-console enable

3.telnet到对应的AP上

telnet 172.16.1.10

Trying 172.16.1.10...

Press CTRL+K to abort

Connected to 172.16.1.10...

4.查看AP对应的信道利用率

sys

[ap01]probe

[ap01-probe]dis ar5drv 2channelbusy //“1”为5G频段，“2”为2.4G频段

ChannelBusy information

Ctl Channel: 06 Channel Band: 20M//“06”表示信道6

Ext Channel:

Record Interval(s): 9

Date/Month/Year: 19/05/2017

//CtlBusy(%)：总繁忙度；TxBusy(%)：发送繁忙度；RxBusy(%)：接收繁忙度

Time(h/m/s): CtlBusy(%) TxBusy(%) RxBusy(%) ExtBusy(%)

01 09:14:54 25 2 22 0

02 09:14:45 23 2 20 0

03 09:14:36 24 2 21 0

04 09:14:27 28 2 25 0

06 09:14:09 26 2 22 0

07 09:14:00 24 2 21 0

08 09:13:51 25 2 22 0

10 09:13:33 25 2 22 0

11 09:13:24 24 2 21 0

12 09:13:15 24 2 21 0

13 09:13:06 27 2 23 0

14 09:12:57 25 2 22 0

15 09:12:48 22 1 20 0

16 09:12:39 25 2 22 0

17 09:12:30 25 1 23 0

18 09:12:21 29 2 26 0

19 09:12:12 26 2 23 0

20 09:12:03 25 2 21 0

注：

TX和RX相加不等于CtlBusy是因为还存在非wifi干扰。TX+RX=wifi干扰

ChanneBusy是以AP的视角查看当前频道的工作情况，而不是本AP对这个信道的使用情况

一般认为60%以上认为信道忙，80%则认为不可用了，建议优化值在40%以内为好。
