H3C S3500-EA NQA UDP Jitter测试的典型配置

H3C S3500-EA NQA UDP Jitter测试的典型配置

一、  组网需求：

使用UDP-jitter功能测试本端（Device A）和指定的目的端（Device B）之间传送报文的时延抖动。

二、  组网图：

三、  配置步骤：

(1) 配置Device B

# 使能NQA服务器，配置监听的IP地址为10.2.2.2，端口号为9000。

<DeviceB> system-view

[DeviceB] nqa server enable

[DeviceB] nqa server udp-echo 10.2.2.2 9000

(2) 配置Device A

# 创建UDP-jitter类型的NQA测试组并配置相关测试参数。

<DeviceA> system-view

[DeviceA] nqa entry admin test

[DeviceA-nqa-admin-test] type udp-jitter

[DeviceA-nqa-admin-test-udp-jitter] destination ip 10.2.2.2

[DeviceA-nqa-admin-test-udp-jitter] destination port 9000

[DeviceA-nqa-admin-test-udp-jitter] quit

# 启动UDP-jitter测试操作。

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

# 测试执行一段时间后，停止UDP-jitter测试操作。

[DeviceA] undo nqa schedule admin test

# 显示UDP-jitter测试中最后一次测试的结果。

[DeviceA] display nqa result admin test

四、  配置关键点：

UDP-jitter测试中每次探测发送一组报文，这组报文对应一条历史记录。因此，如果想了解UDP-jitter测试的结果，建议通过display nqa result命令来查看探测结果，不要通过display nqa history命令查看历史记录
