在华为Wlan中,特别是部署了很多的AP,信道间肯定有干扰,这个时候可以开启射频调优功能自动选择AP最佳信道和功率,不过实际的工作中,信道调优还可以,关于自动功率调优是不建议的

# 创建RRM模板“wlan-rrm”,在RRM模板下使能信道自动选择信道功能和发送功率自动选择信道功能。缺省情况下,信道自动选择信道功能和发送功率自动选择信道功能都已经使能。

[AC-wlan-view] rrm-profile name wlan-rrm
[AC-wlan-rrm-prof-wlan-rrm] undo calibrate auto-channel-select disable
[AC-wlan-rrm-prof-wlan-rrm] undo calibrate auto-txpower-select disable
[AC-wlan-rrm-prof-wlan-rrm] quit

# 在域管理模板下配置调优信道集合。

[AC-wlan-view] regulatory-domain-profile name default
[AC-wlan-regulate-domain-default] dca-channel 2.4g channel-set 1,6,11
[AC-wlan-regulate-domain-default] dca-channel 5g bandwidth 20mhz
[AC-wlan-regulate-domain-default] dca-channel 5g channel-set 149,153,157,161
[AC-wlan-regulate-domain-default] quit

# 创建空口扫描模板“wlan-airscan”,并配置调优信道集合、扫描间隔时间和扫描持续时间。

[AC-wlan-view] air-scan-profile name wlan-airscan
[AC-wlan-air-scan-prof-wlan-airscan] scan-channel-set dca-channel
[AC-wlan-air-scan-prof-wlan-airscan] scan-period 60              //单位是毫秒
[AC-wlan-air-scan-prof-wlan-airscan] scan-interval 60000
[AC-wlan-air-scan-prof-wlan-airscan] quit

# 创建2G射频模板“wlan-radio2g”,并在该模板下引用RRM模板“wlan-rrm”和空口扫描模板“wlan-airscan”

[AC-wlan-view] radio-2g-profile name wlan-radio2g
[AC-wlan-radio-2g-prof-wlan-radio2g] rrm-profile wlan-rrm
[AC-wlan-radio-2g-prof-wlan-radio2g] air-scan-profile wlan-airscan
[AC-wlan-radio-2g-prof-wlan-radio2g] quit

# 创建5G射频模板“wlan-radio5g”,并在该模板下引用RRM模板“wlan-rrm”和空口扫描模板“wlan-airscan”

[AC-wlan-view] radio-5g-profile name wlan-radio5g
[AC-wlan-radio-5g-prof-wlan-radio5g] rrm-profile wlan-rrm
[AC-wlan-radio-5g-prof-wlan-radio5g] air-scan-profile wlan-airscan
[AC-wlan-radio-5g-prof-wlan-radio5g] quit

# 在名为“ap-group1”“ap-group2”AP组下引用5G射频模板“wlan-radio5g”2G射频模板“wlan-radio2g”

[AC-wlan-view] ap-group name ap-group1
[AC-wlan-ap-group-ap-group1] radio-5g-profile wlan-radio5g radio 1
Warning: This action may cause service interruption. Continue?[Y/N]y
[AC-wlan-ap-group-ap-group1] radio-2g-profile wlan-radio2g radio 0
Warning: This action may cause service interruption. Continue?[Y/N]y
[AC-wlan-ap-group-ap-group1] quit
[AC-wlan-view] ap-group name ap-group2
[AC-wlan-ap-group-ap-group2] radio-5g-profile wlan-radio5g radio 1
Warning: This action may cause service interruption. Continue?[Y/N]y
[AC-wlan-ap-group-ap-group2] radio-2g-profile wlan-radio2g radio 0
Warning: This action may cause service interruption. Continue?[Y/N]y
[AC-wlan-ap-group-ap-group2] quit

# 配置射频调优模式为手动调优,并手动触发射频调优。

[AC-wlan-view] calibrate enable manual
[AC-wlan-view] calibrate manual startup

# 待执行手动调优一小时后,调优结束。将射频调优模式改为定时调优,并将调优时间定为用户业务空闲时段(如当地时间凌晨00:00-06:00时段)。

[AC-wlan-view] calibrate enable schedule time 03:00:00

关于华为Wlan的理论知识点,其实还有蛮多蛮多的,这儿仅仅是做了一个射频调优的笔记。
