UCCE Server/Client Tool Use to Troubleshoot the Network

Introduction

This document describes the Server/Client tool and provides clarification about the output generated and the usage parameters. The Server/Client tool is supplied with all Unified Contact Center Enterprise (UCCE) versions and is located in the c:\icm\bin folder. It can be useful in order to troubleshoot the network or to prove that the network has problems. Network issue identification is important in the UCCE environment, because the usual ping command does not provide a full picture of the network.

Setup

Here are the steps for quick setup:

1. On Router B (PGB), open a command prompt window and input:
   
   

   server ServerHighIPAddress 50001 /rptintvl 10000

   
   

   Note: For the command, enter the high priority IP address of Router B for the ServerHighIPAddress.

   
   
   
2. On the Router A (PGA), open a command prompt window and input:
   
   

   client ServerHighIPAddress 50001 /localaddr ClientHighIPAddress
    
    /htbt 1 /msgintvl 100 /burst 30 /msgsize 1000
    
    /rptintvl 10000 /bucketsize 50

   
   

   Note: For the command, enter the the high priority IP address of Router B (PGB) for the ServerHighIPAddress and the high priority IP address of Router A (PGA) for the ClientHighIPAddress.

   
   
   This generates approximately 2.4Mbps of high priority traffic bidirectionally. The tool prints a report after every 10,000 packets (rptintvl value in number of packets).
   
   
3. Manually stop the tool with Ctrl-c after the test is complete. The .exe files are located in the C:\icm\bin, which should be in the path already.

Usage Parameters

This section provides clarification about the usage parameters.

/bucketsize - The size of the bucket into which the report classifies packets with a certain range of Round Trip Time (RTT) delay. For example, this output shows a bucket size of 50ms:

11:10:28 After 30000: min rtt = 0ms, max rtt = 94ms, avg rtt = 1ms

0- 49:9978 -> 9978 packets with RTT between 0 and 49 - first bucket

50- 99:22 -> 22 packets with RTT between 50 and 99 - second bucket

100- 149:0 -> 0 packets with RTT between 100 and 149 - third bucket

/rptintvl - The report interval in number of packets. The report is printed whenever the number of packets specified here is reached.

/msgsize - The size of the message sent in bytes. This value together with the /msgintvl value determines the amount of bandwidth consumed with the test.

In order to check bandwidth consumption during the test, access the Task Manager > Network tab:
