H3C-S5560無線控制模塊信道利用率查看優化

H3C-S5560無線控制模塊信道利用率查看優化

 

1.查看要排查無線AP的IP地址

<JF-S5560>dis wlan ap name ap01 address //「ap01」AP名稱

AP name                IP address              MAC address

ap01                  172.16.1.10              ac74-09d8-5960

 

2.開啓對應AP的telnet功能

<JF-S5560>sys

[JF-S5560]probe

[JF-S5560-probe]wlan ap-execute ap01 exec-console enable

 

3.telnet到對應的AP上

<JF-S5560>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對應的信道利用率

<ap01>sys

[ap01]probe

[ap01-probe]dis ar5drv 2 channelbusy //「1」爲5G頻段，「2」爲2.4G頻段

 

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(%)：總繁忙度；TxBusy(%)：發送繁忙度；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

 05     09:14:18         26          2         23          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

 09     09:13:42         24          2         21          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相加不等於CtlBusy是由於還存在非wifi干擾。TX+RX=wifi干擾

ChanneBusy是以AP的視角查看當前頻道的工做狀況，而不是本AP對這個信道的使用狀況

通常認爲60%以上認爲信道忙，80%則認爲不可用了，建議優化值在40%之內爲好。
