无线AP绑定的SSID，是否可以随机分配给不同的VLAN管理

组网需求

如图1所示，Switch作为DHCP服务器为AP和Client分配IP地址，在AC上配置两个VLAN组，VLAN-group test1和VLAN-group test2。现要求：Client分别接入不同VLAN组，VLAN组可以为Client随机分配组内的VLAN，使Client被均衡地分配在所有VLAN中。

3.2  配置步骤

3.2.1  配置AC

(1)     配置AC的接口

# 创建VLAN 2及其对应的VLAN接口，并为该接口配置IP地址192.12.0.2/16。AP将获取该IP地址与AC建立CAPWAP隧道。

<AC> system-view

[AC] vlan 10

[AC-vlan10] quit

[AC] interface vlan-interface 10

[AC-Vlan-interface10] ip address 192.10.0.2 16

[AC-Vlan-interface10] quit

[AC-wlan-st-1] client vlan-alloc static

# 开启无线服务模板。

[AC-wlan-st-1] service-template enable

[AC-wlan-st-1] quit

(4)     配置AP

# 创建手工AP，配置AP名称为ap1，型号为WA5320，序列号为219801A0YDC14C000225。

[AC] wlan ap ap1 model WA5320

[AC-wlan-ap-ap1] serial-id 219801A0YDC14C000225

# 进入ap1的Radio 1视图，并将无线服务模板1绑定到Radio 1上，同时指定VLAN-group。

[AC-wlan-ap-ap1] radio 1

[AC-wlan-ap-ap1-radio-1] service-template 1 vlan-group test1

# 开启Radio 1的射频功能。

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

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

[AC-wlan-ap-ap1] quit

[AC-wlan-ap-ap2] radio 1

[AC-wlan-ap-ap2-radio-1] service-template 1 vlan-group test2

# 开启Radio 1的射频功能。

[AC-wlan-ap-ap2-radio-1] radio enable

[AC-wlan-ap-ap2-radio-1] quit

[AC-wlan-ap-ap2] quit

3.2.2  配置Switch
