WX 3520X AC 客戶端Seamless roam漫游怎么开启

您好，参考

2.6.9  Wi-Fi 6零漫游医疗场景典型配置举例

1. 组网需求

如图2-9所示，网络中的大部分无线客户端支持802.11k和802.11v协议，通过配置Wi-Fi 6零漫游功能，实现无线客户端在一个ESS（Extended Service Set，拓展服务集）区域中的无缝漫游。

2. 组网图

图2-9 Wi-Fi 6零漫游医疗场景配置组网图

3. 配置步骤

# 创建无线服务模板wifi6_zero。

<AC> system-view

[AC] wlan service-template wifi6_zero

# 配置无线服务的SSID为wifi6_zero。

[AC-wlan-st-wifi6_zero] ssid wifi6_zero

# 开启BSS切换管理功能。

[AC-wlan-st-wifi6_zero] bss transition-management enable

# 配置切换解除关联功能。

[AC-wlan-st-wifi6_zero] bss transition-management disassociation recommended timer 45

# 开启漫游优化流量保持高级功能。

[AC-wlan-st-wifi6_zero] sacp roam-optimize traffic-hold enable advanced

# 开启FT功能。

[AC-wlan-st-wifi6_zero] ft enable

# 使能无线服务。

[AC-wlan-st-wifi6_zero] service-template enable

[AC-wlan-st-wifi6_zero] quit

# 创建手工AP，名称为ap1，序列号为219801A28N819CE0002T。

[AC] wlan ap ap1 model WA6320

[AC-wlan-ap-ap1] serial-id 219801A28N819CE0002T

# 进入Radio 1视图。

[AC-wlan-ap-ap1] radio 1

# 开启射频资源测量功能。

[AC-wlan-ap-ap1-radio-1] resource-measure enable

# 开启获取BSS候选列表功能。

[AC-wlan-ap-ap1-radio-1] sacp roam-optimize bss-candidate-list enable

# 配置射频每2秒进行信号强度检测，在支持802.11v的无线客户端信号强度低于-30dBm时，引导其进行BSS切换，对不支持802.11v的客户端强制下线处理。

[AC-wlan-ap-ap1-radio-1] sacp anti-sticky enable rssi 30 interval 2 forced-logoff

# 将无线服务模板wifi6_zero绑定到ap1的Radio1上。

[AC-wlan-ap-ap1-radio-1] service-template wifi6_zero

[AC-wlan-ap-ap1-radio-1] radio enable

[AC-wlan-ap-ap1-radio-1] quit

[AC-wlan-ap-ap1] quit

# （可选）配置对无线客户端进行差异化反粘滞管控制。

·     创建ACL规则，将CCC9-5DE2-512D终端按照OUI匹配规则加入到弱信号ACL匹配规则中。

[AC] acl number 4500

[AC-acl-mac-4500] rule permit source-mac ccc9-5de2-512d ffff-ff00-0000

[AC-acl-mac-4500] quit

·     指定编号为4500的ACL匹配的无线客户端，在信号强度低于-25dBm时，由AP引导其进行BSS切换。

[AC] wlan ap ap1

[AC-wlan-ap-ap1] radio 1

[AC-wlan-ap-ap1-radio-1] sacp anti-sticky acl 4500 rssi 25

[AC-wlan-ap-ap1-radio-1] quit

[AC-wlan-ap-ap1] quit

4. 验证配置
