This chapter describes use cases for running applications on IOS XR.

Hosting iPerf in Docker Containers to Measure Network Performance using Application Manager

Measuring the network performance is important to test the efficiency of the network. Network throughput, bandwidth, latency, and packet loss are some of the parameters used to measure the network performance. iPerf is a commonly used application for measuring network performance. The iPerf application is hosted on systems at both ends of the connection that is measured. One system is used as the server, and the other system is used as the client. At least one system must be a Cisco IOS XR router, the other system can be any other external entity like a controller or another router.

This use case illustrates the procedure for hosting the iPerf application in docker containers on two Cisco IOS XR routers, Router A and Router B to measure network performance. Router A hosts the iPerf server and Router B hosts the iPerf client.

In this usecase, we demonstrate the example of testing network bandwidth when a route update takes place. Router A hosts the iPerf Server and Router B hosts the iPerf Client. Router C and Router D are intermediate routers that allow traffic flow from Router A to Router B and vice-versa.
Figure 1. Hosting iPerf Application in Cisco IOS XR Routers

Verify Connection between Router A and Router B

The ping command verifies the connection between the IOS XR software on the routers, while the bash ping command verifies the connection between the linux kernel that hosts the IOS XR software on the routers.

Procedure

Check the connection between Router A and Router B using the ping and bash ping commands.

Install the iPerf Server Application

Procedure

Step 1

Install the iPerf application RPM on Router A. Only the RPM file format is supported. 

Router#appmgr package install rpm /misc/disk1/iperf-0.1.0-XR_7.3.1.x86_64.rpm

Router#show appmgr source-table

Step 2

Configure the application to run as iPerf server.

Router#config
Thu Dec  3 09:57:54.034 UTC
Router(config)#appmgr
Router(config-appmgr)#application iperf-server-app
Router(config-application)#activate type docker source iperf docker-run-opts "--net=host" docker-run-cmd "iperf3 -s -d"
Router(config-application)#commit
Thu Dec  3 09:57:54.398 UTC
Step 3

Verify the basic details (application name and state) about the activated iPerf server application.

Install the iPerf Client Application

Procedure

Step 1

Install the iPerf application RPM on Router B. 

Router#appmgr package install rpm /misc/disk1/iperf-0.1.0-XR_7.3.1.x86_64.rpm
Router#show appmgr source-table

Step 2

Configure the application to run as iPerf client with a timeout (600s in this case).

Router#config
Thu Dec  3 09:57:54.034 UTC
Router(config)#appmgr
Router(config-appmgr)#application iperf-client-app
Router(config-application)#activate type docker source iperf docker-run-opts "--net=host" docker-run-cmd "iperf3 -c 30.5.7.1 -t 600"
Router(config-application)#commit
Thu Dec  3 09:57:54.398 UTC
Note 

Hosting the iPerf client application on Router B by providing the iPerf server physical interface IP address (30.5.7.1) establishes communication between Router B and Router A.

Step 3

Verify the basic details (application name and state) about the activated iPerf client application.

Step 2

Check the network performance between iPerf client and iPerf server (on Router B and Router A).

You can view the network monitoring parameters by executing the show appmgr application name iperf-client-app logs command, on Router B that hosts the iPerf client.

Step 3

Bring down the interface on Router D using the shut command to trigger a route update. 

Router(config)#interface FourhundredGig0/0/0/0
Router(config-if)#shut
Router(config-if)#commit
Note 

Because of the interface shutdown, the route to 30.5.7.1 needs to be updated and hence momentarily there will be no route to this address.

Step 4

During the route update, check the network performance by executing the show appmgr application name app_name logs command.

You will notice that the entries in the Bandwidth field is Zero for a short duration, when the new route is installed.

Stop iPerf Applications

Procedure

Stop the iPerf applications on Router A and Router B using the appmgr application stop name app_name command. The application stop command can only be used for applications that are registered, activated, and are currently running. The application stop command stops only the application and does not clean up the resources used by the application.

You can verify the status of the application using the show appmgr application-table command. The Status is displayed as Exited if the application has been stopped successfully. 

Router#appmgr application stop name iperf-server-app

Start iPerf Applications

Procedure

Start or restart an application that has been stopped (and not deactivated) using the appmgr application start name app_name command. 

Router#appmgr application start name iperf-server-app

Router#

Deactivate iPerf Applications

Procedure

Step 1

Deactivate the iPerf applications using the no appmgr application app_name command. You deactivate the installed application when you want to release all resources used by the application. 

Router#config
Router(config)#no appmgr application iperf-server-app
Router(config)#commit
Step 2

Verify the status of the application by using the show appmgr application-table app_name stats command. 

Router#show appmgr application-table
Mon Nov 30 13:39:51.197 UTC
Router#
Note 

You can activate a deactivated application using the appmgr application app_name activate type docker source source_name command.

Uninstall iPerf Applications

Procedure

Uninstall the applications using the appmgr package uninstall package package_name command.

After the application is successfully uninstalled, executing the show appmgr source-table command displays no result. 

Router#appmgr package uninstall package iperf
table
Mon Nov 30 13:41:05.155 UTC
Router#show appmgr source-table
