示例：在 MX、M、T 和 PTX 系列路由器上配置实时性能监控
配置由探测名称和 probe1 测试名称 test1标识的 RPM 实例：
[edit services rpm]
probe probe1{
test test1 {
dscp-code-points 001111;
probe-interval 1;
probe-type icmp-ping;
target address 172.17.20.182;
test-interval 20;
thresholds rtt 10;
traps rtt-exceeded;
}
}
probe-server {
tcp {
destination-interface lt-0/0/0.0
port 50000;
}
udp {
destination-interface lt-0/0/0.0
port 50001;
}
}
probe-limit 200;
配置数据包分类，使用 lt- 接口将探测数据包发送到逻辑隧道输入接口。通过将数据包发送至逻辑隧道接口，可以为探测数据包配置常规分类器和多域分类器、防火墙过滤器以及标头重写。要使用现有隧道框架， dlci 必须配置 and encapsulation 语句。
[edit services rpm]
probe p1 {
test t1 {
probe-type icmp-ping;
target address 10.8.4.1;
probe-count 10;
probe-interval 10;
test-interval 10;
source-address 10.8.4.2;
dscp-code-points ef;
data-size 100;
destination-interface lt-0/0/0.0;
}
}
[edit interfaces]
lt-0/0/0 {
unit 0 {
encapsulation frame-relay;
dlci 10;
peer-unit 1;
family inet;
}
unit 1 {
encapsulation frame-relay;
dlci 10;
peer-unit 0;
family inet;
}
}
[edit class-of-service]
interfaces {
lt-0/0/0 {
unit 1 {
classifiers {
dscp default;
}
}
}
}
在接收 RPM 探测的接口上配置输入过滤器。此过滤器支持对收到的 RPM 数据包进行优先级划分，使它们与同一接口上收到的常规数据包分离。
[edit firewall]
filter recos {
term recos {
from {
source-address {
10.8.4.1/32;
}
destination-address {
10.8.4.2/32;
}
}
then {
loss-priority high;
forwarding-class network-control;
}
}
}
[edit interfaces]
fe-5/0/0 {
unit 0 {
family inet {
filter {
input recos;
}
address 10.8.4.2/24;
}
}
}
配置 RPM 实例并为自适应服务接口上的扩展提供商软件包启用 RPM：
[edit services rpm]
probe probe1{
test test1 {
data-size 1024;
data-fill 0;
destination-interface ms-1/2/0.10;
dscp-code-points 001111;
probe-count 10;
probe-interval 1;
probe-type icmp-ping;
target address 172.17.20.182;
test-interval 20;
thresholds rtt 10;
traps rtt-exceeded;
}
}
[edit interfaces]
ms-1/2/0 {
unit 0 {
family inet;
}
unit 10 {
rpm client;
family inet {
address 192.0.2.1/32;
}
}
[edit chassis]
fpc 1 {
pic 2 {
adaptive-services {
service-package {
extension-provider {
control-cores 1;
data-cores 1;
object-cache-size 512;
policy-db-size 64;
package jservices-rpm;
syslog {
daemon any;
}
}
}
}
}
}
配置启用 TWAMP 所需的最小语句：
[edit services]
rpm {
twamp {
server {
authentication-mode none;
port 10000; # Twamp server's listening port
client-list LIST-1 { # LIST-1 is the name of the client-list. Multiple lists can be configured.
address {
198.51.100.2/30; # IP address of the control client.
}
}
}
}
[edit interfaces sp-5/0/0]
unit 0 {
family inet;
}
unit 10 {
rpm {
twamp-server; # You must configure a separate logical interface on the service PIC interface for the TWAMP server.
}
family inet {
address 203.0.113.50/32; # This address must be a host address with a 32-bit mask.
}
}
[edit chassis]
fpc 5 {
pic 0 {
adaptive-services {
service-package layer-2; # Configure the service PIC to run in Layer 2 mode.
}
}
}
配置其他 TWAMP 设置：
[edit services]
rpm {
twamp {
server {
maximum-sessions 5;
maximum-sessions-per-connection 2;
maximum-connections 3;
maximum-connections-per-client 1;
port 10000;
server-inactivity-timeout ;
client-list LIST-1 {
address {
198.51.100.2/30;
}
}
}
}
}
