示例：在 MX 系列路由器上配置 TWAMP 客户端和服务器
此示例说明如何配置 TWAMP 客户端和服务器，并包含以下部分。
要求
此示例使用以下硬件和软件组件：
-
MX 系列路由器。
-
Junos OS 15.1 或更高版本。
概述
此示例说明了双向主动测量协议 （TWAMP）。TWAMP 是一种开放式协议，用于测量支持 TWAMP 协议的任何两台设备之间的网络性能。TWAMP 控制协议用于设置性能测量会话。TWAMP-Test 协议用于发送和接收性能测量探针。
TWAMP 架构由以下实体组成，这些实体负责开始监控会话并交换数据包：
-
控制客户端会发送“开始会话”消息启动所有请求的测试会话，服务器会进行确认。如有必要，控制客户端会发送一条消息以停止所有测试会话。
-
会话发送方和会话反射器根据每个活动会话的 TWAMP-Test 协议交换测试数据包。接收 TWAMP-Test 数据包时，会话反射器仅反射测量数据包，不会在 TWAMP 中收集数据包统计信息。
TWAMP 服务器是管理一个或多个 TWAMP 会话的终端系统，并且能够配置每个会话端口。服务器侦听 TCP 端口。在 IP 服务级别协议操作中，会话反射器与服务器组成 TWAMP 响应程序。
对于 15.1，控制客户端和会话发件人都将驻留在同一个瞻博网络路由器上。客户端设计不会强制服务器和会话反射器在同一系统上。因此，瞻博网络 TWAMP 客户端也将能够处理第三方服务器实施。
TWAMP 客户端的配置
CLI 快速配置
要快速配置此示例，请复制以下命令，将其粘贴到文本文件中，删除所有换行符，更改详细信息，以便与网络配置匹配，然后将命令复制并粘贴到 SG1 路由器的 [编辑] 层次结构级别的 CLI 中。
配置机箱
set chassis fpc 4 pic 1 inline-services bandwidth 1g
配置接口
set interfaces si-4/1/0 unit 0 family inet set interfaces si-4/1/0 unit 10 rpm twamp-client set interfaces si-4/1/0 unit 10 family inet address 10.60.60.1/32
配置服务
set services rpm twamp client control-connection c1 destination-interface si-4/1/0.10 set services rpm twamp client control-connection c1 history-size 500 set services rpm twamp client control-connection c1 target-address 10.70.70.1 set services rpm twamp client control-connection c1 test-count 1 set services rpm twamp client control-connection c1 test-interval 1 set services rpm twamp client control-connection c1 traps test-iteration-done set services rpm twamp client control-connection c1 traps control-connection-closed set services rpm twamp client control-connection c1 test-session t1 target-address 10.70.70.1 set services rpm twamp client control-connection c1 test-session t1 data-fill-with-zeros set services rpm twamp client control-connection c1 test-session t1 data-size 1400 set services rpm twamp client control-connection c1 test-session t1 probe-count 55 set services rpm twamp client control-connection c1 test-session t1 probe-interval 1
配置 TWAMP 客户端
逐步过程
以下示例要求您在配置层次结构中的各个级别上导航。
-
配置机箱。
[edit chassis] user@router1# set fpc 4 pic 1 inline-services bandwidth 1g
-
配置接口。
[edit interfaces] user@router1# set si-4/1/0 unit 0 family inet user@router1# set si-4/1/0 unit 10 rpm twamp-client user@router1# set si-4/1/0 unit 10 family inet address 10.60.60.1/32
-
配置服务。
[edit services] user@router1# set rpm twamp client control-connection c1 destination-interface si-4/1/0.10 user@router1# set rpm twamp client control-connection c1 history-size 500 user@router1# set rpm twamp client control-connection c1 target-address 10.70.70.1 user@router1# set rpm twamp client control-connection c1 test-count 1 user@router1# set rpm twamp client control-connection c1 test-interval 1 user@router1# set rpm twamp client control-connection c1 traps test-iteration-done user@router1# set rpm twamp client control-connection c1 traps control-connection-closed user@router1# set rpm twamp client control-connection c1 test-session t1 target-address 10.70.70.1 user@router1# set rpm twamp client control-connection c1 test-session t1 data-fill-with-zeros user@router1# set rpm twamp client control-connection c1 test-session t1 data-size 1400 user@router1# set rpm twamp client control-connection c1 test-session t1 probe-count 55 user@router1# set rpm twamp client control-connection c1 test-session t1 probe-interval 1
结果
在路由器 1 的配置模式下，输入 、 show interfaces和show services rpm twamp命令，show chassis以确认您的配置。如果输出未显示预期的配置，请重复此示例中的说明，以更正配置。
user@router1# show chassis
fpc 4 {
pic 1 {
inline-services {
bandwidth 1g;
}
}
}
user@router1# show interfaces
si-4/1/0 {
unit 0 {
family inet;
}
unit 10 {
rpm twamp-client;
family inet {
address 10.60.60.1/32;
}
}
}
user@router1# show services rpm twamp
client {
control-connection c1 {
destination-interface si-4/1/0.10;
history-size 500;
target-address 10.70.70.1;
test-count 1;
test-interval 1;

}
test-session t1 {
