1 WLAN上行链路检测

1.1  WLAN上行链路检测简介

当AC的上行链路出现故障时，该AC将无法提供访问外部网络的服务，而已关联的无线客户端无法感知AC上行链路的故障，因此不能自动切换接入的无线网络。通过配置WLAN上行链路检测功能，可以将AC下的AP射频状态与上行链路状态进行关联，及时关闭不能正常提供服务的射频，使无线客户端能够主动切换至其它无线网络。

上行链路检测功能的实现方式是将监测模块、Track项与WLAN上行链路检测模块进行联动。监测模块负责监测上行链路的可达性；Track模块根据监测模块的监测结果改变Track项的状态；WLAN上行链路检测模块根据Track项的状态调整射频的工作状态：

·     如果Track项状态为Positive，则允许开启AP射频。

·     如果Track项状态为Negative，则关闭AP射频。

·     如果Track项状态为NotReady，则不更改AP射频的当前状态。

1.2  WLAN上行链路检测与Track项联动配置限制和指导

为使WLAN上行链路检测功能能够正常运行，需要先配置对上行链路进行监测的监测模块，并将配置的监测模块与Track进行联动。

1.3  配置WLAN上行链路检测与Track项联动

(1)     进入系统视图。

system-view

(2)     配置WLAN上行链路检测与Track项联动。

wlan uplink track track-entry-number

缺省情况下，未配置WLAN上行链路检测与任何Track项联动。

1.4  WLAN上行链路检测典型配置举例

1.4.1  WLAN上行链路检测基本组网典型配置举例

1. 组网需求

AC 1管理的AP 1和AC 2管理的AP 2共同为一个区域的无线客户端提供服务。要求在AC上配置WLAN上行链路检测功能，使用NQA测试组监测上行链路可达性。当AC发现上行链路出现故障，其管理的AP的Radio将被关闭，让客户端仅可以通过上行链路正常工作的AC下的AP接入网络。

2. 组网图

3. 配置步骤

(1)     配置AC 1

# 创建ICMP-echo类型的NQA测试组。

<AC1> system-view

[AC1] nqa entry admin test

[AC1-nqa-admin-test] type icmp-echo

# 配置ICMP-echo测试操作中探测报文的目的IPv4地址为10.1.1.1。

[AC1-nqa-admin-test-icmp-echo] destination ip 10.1.1.1

# 配置测试组连续两次测试开始时间的时间间隔为1000毫秒。

[AC1-nqa-admin-test-icmp-echo] frequency 1000

# 建立序号为1的联动项，连续探测失败5次，触发其他模块联动。

[AC1-nqa-admin-test-icmp-echo] reaction 1 checked-element probe-fail threshold-type consecutive 5 action-type trigger-only

[AC1-nqa-admin-test-icmp-echo] quit

# 启动ICMP-echo测试操作。

[AC1] nqa schedule admin test start-time now lifetime forever

# 创建与NQA测试组（管理员为admin，操作标签为test）中联动项1关联的Track项1。

[AC1] track 1 nqa entry admin test reaction 1

[AC1-track-1] quit

# 配置上行链路检测与Track项1关联。

[AC1] wlan uplink track 1

[AC1] quit

(2)     配置AC 2

# 创建ICMP-echo类型的NQA测试组。

<AC2> system-view

[AC2] nqa entry admin test

[AC2-nqa-admin-test] type icmp-echo

# 配置ICMP-echo测试操作中探测报文的目的IPv4地址为11.1.1.1。

[AC2-nqa-admin-test-icmp-echo] destination ip 11.1.1.1

# 建立序号为1的联动项，连续探测失败5次，触发其他模块联动。

[AC2-nqa-admin-test-icmp-echo] reaction 1 checked-element probe-fail threshold-type consecutive 5 action-type trigger-only

[AC2-nqa-admin-test-icmp-echo] quit

# 启动ICMP-echo测试操作。

[AC2] nqa schedule admin test start-time now lifetime forever

# 创建与NQA测试组（管理员为admin，操作标签为test）中联动项1关联的Track项1。

[AC2] track 1 nqa entry admin test reaction 1

# 配置上行链路检测与Track项1关联。

[AC2] wlan uplink track 1

[AC2] quit

4. 验证结果

# 完成以上配置后，通过display track命令和display wlan ap命令查看Track项的信息和AP的信息可以看到当Track项状态为Positive时，AP的射频状态为Up。
