Real@Time&Performance&Monitoring&(RPM)&

Objective!

To validate the ability of Juniper EX Series switches to perform real-time health checks

on attached devices.

Background!

Juniper’s Real-Time Performance Monitoring (RPM) feature can perform “health

checks” on attached network devices and servers using ICMP, HTTP, TCP and UDP

probes and requests. These active probes monitor devices across any network and

investigate reachability problems. RPM keeps a history of the most recent 50 probes;

such monitoring over time can be useful in troubleshooting and capacity planning.

Topology!

In this example, a Juniper Virtual Chassis comprising two Juniper EX9208 switches uses

uses ICMP probes to monitor round-trip times between it and a Cisco Catalyst 3850E

switch. Note that no RPM-specific commands are needed on the Cisco switch. The

same RPM configuration on the Juniper switch will work with any Cisco switch, or

indeed any remote device capable of responding to pings (ICMP probe requests).

Figure 11 illustrates the RPM validation test bed. The Juniper Virtual Chassis in this

example uses an IP address of 192.18.0.10/24 assigned to interface xe-5/3/1. This

interface sends ICMP probe requests to a Cisco switch with an address of

192.18.0.1/24. The same RPM configuration would work in a Juniper switch

configuration in which a VLAN is created and an IP address is assigned to the VLAN.
