    362362To configure the latency and bandwidth tests we want for our slice we go to the ''Scheduled Tests'' configuration page. We will not cover the configuration tool in details in this quick start guide. Please refer to the [http://code.google.com/p/perfsonar-ps/wiki/pSPerformanceToolkit31#Scheduled_Testing Scheduled Testing section] of the pS-Performance Toolkit Tutorial for a detailed explanation of the configuration tool. We will only cover the modifications done to the interface for LAMP.

    364 The first difference is the ability to select which node we want to configure. These tests are always scheduled in a '''star''' configuration, with the node where the tests are being configured as the source endpoint of the test. We will configure the following scheduled tests on our slice:
    365 
    366 * '''node1:''' 
     364The first difference is the ability to select which node we want to configure. These tests are always scheduled in a '''star''' configuration, originating from the node where the tests are being configured. However, OWAMP (one-way latency) and BWCTL (throughput) tests will run in both directions (managed by the same node). We will configure the following scheduled tests on our slice:
     365
     366* '''node1:''' Ping test (default parameters) to node2. One-way delay test (default parameters) to node2.
     367
     368* '''node2:''' Throughput test to node1 at 15 minutes interval (all other parameters default). Note that only ''iperf'' is currently installed on the LAMP image.
     369
     370Another change from the pS-Performance Toolkit is that we restrict the hosts that can be selected as targets for the tests to the nodes in the slice topology. We use the localname of each node so that the addresses on the virtual topology will be used for the tests (i.e. tests will not go through the control plane). The configuration for each node should look like this:

     372[[Image(node1-pinger.png)]]
     373[[Image(node1-owd.png)]]
     374[[Image(node2-bwctl.png)]]
