This chapter describes preparing to install and installing the TrafficDirector application on an AIX system. It consists of:
The TrafficDirector application lets you monitor and record information about network usage, events, and trends, and identify and isolate many fault conditions.
The TrafficDirector application consists of a centralized, SNMP-compatible network management console and data-gathering agents located at various points on a network.
You can use the TrafficDirector application to perform several basic functions:
Before beginning the installation, consider the following:
 |
Caution Cisco Systems strongly recommends that you use the default installation path of /usr/CSCOtd. If you wish to override the default and install the software in a preexisting location, you must install the software in a directory subordinate to that location (for example, /alternate_location/CSCOtd). |
The following sections describe prerequisites and other factors you should consider before installing the TrafficDirector application.
To view the online help, you must install a web browser on the UNIX workstation on which the TrafficDirector software will be installed. This installation supports Netscape Navigator, Release 4.61.
Table 2-1 shows the minimum system requirements for the TrafficDirector application.
| Requirement Type | Minimum Requirement |
|---|---|
System hardware |
|
256 MB minimum. | |
Available disk space |
|
Additional software | You must install CiscoWorks2000 CD One first if you are upgrading to Campus Manager 3.0. For more information, see Installing and Setting Up CiscoWorks2000 CD One on HP-UX and AIX. |
 |
Note You can upgrade to TrafficDirector Release 5.8 on systems running TrafficDirector 5.5.x or later. |
TrafficDirector Release 5.8 is part of the LAN Management Solutions (LMS) bundle. If the CWSI Campus package is installed on your system, and you upgrade to Campus Manager 3.0, the data from the older version of the TrafficDirector application is backed up. The TrafficDirector application is upgraded to the TrafficDirector Release 5.8 and the backed-up data restored.
If the standalone version of the TrafficDirector application is installed on your system, and you are upgrading to TrafficDirector Release 5.8, you must follow the installation procedure described in the next section, "Installing the TrafficDirector Application."
|
Caution If you are installing the TrafficDirector application as part of the Campus Manager 3.0 package, you must install CiscoWorks2000 CD One before you can install the TrafficDirector application. For more information, see Installing and Setting up CiscoWorks2000 CD One on HP-UX and AIX. |
To run the installation program, follow these steps:
Step 2 Log into the system as the root user.
Step 3 If the CD is not already mounted, enter the following command and press Enter:
mount -r -F hsfs /dev/sr0 /cdrom
|
Note The actual syntax you use may differ slightly depending on your system configuration. Substitute the appropriate values where necessary. For more information see, "Mounting and Unmounting a CD-ROM." |
Step 4 To change directories, enter the following command and press Enter:
cd /cdrom/disk1
Step 5 To run the installation script, enter the following command and press Enter:
./setup.sh
|
Note To stop the installation procedure at any time, press Ctrl-C. This command terminates the last UNIX command you entered and returns you to the shell prompt. Continue the installation by reentering the last UNIX command, or discontinue the installation procedure. |
Step 6 If you are installing the TrafficDirector application for the first time, the installation script prompts you to enter the product location. Accept the default location of /usr/CSCOtd or enter an alternate installation location and go to
Step 10.
|
Caution Cisco Systems strongly recommends that you use the default installation path of /usr/CSCOtd. To override the default and install the software in a preexisting location, you must install the software in a directory subordinate to that location (for example, /alternate_location/CSCOtd). |
If a previous version of the TrafficDirector application is already installed on your system, the following message is displayed:
If you proceed, Setup will archive key data in the current versions of TrafficDirector prior to removing them from the server. As this setup completes and you proceed to install programs of the new versions of Resource Management Essentials and/or Campus TrafficDirector the data archived by this Setup program can be imported to the new version. If you do not want older versions impacted at this time, exit this setup program and restart it on a server that does not have the above products loaded on it. Do you want to proceed (y/n)? [y]
Step 7 Press Enter to continue.
The installation script prompts you to enter the location where the data from the current versions will be backed up. The default directory is /opt/CW2000/OldData
Step 8 To choose the default location, press Enter or give a different path where the data will be backed up and press Enter.
The following message is displayed:
Uninstall TrafficDirector (y/n)? [y]
Step 9 To uninstall the previous version of TrafficDirector, enter Y, or enter N to abort the installation.
Step 10 The installation script prompts you to enter the full Netscape browser executable pathname.
The following message is displayed:
Enter the full netscape browser executable pathname: ? [/usr/netscape/netscape]
|
Note The installation procedure does not allow you to leave this information blank, but does allow you to specify an incorrect location during the installation. The installation procedure recognizes the location as incorrect, but allows you to continue. You must correct this after completing the installation. If you set the browser path incorrectly, users cannot use the TrafficDirector online help. See the "Configuring a Web Browser" section for configuration instructions. |
To accept the default location, press Enter, or enter the absolute path to your installed web browser and press Enter.
Step 11 The installation script prompts you to confirm that the installation location and browser executable path are correct. The following message is displayed:
Are these values correct (y/n)? [y]
Step 12 If correct, press Enter, or enter N and press Enter to change the information. If the TrafficDirector installation finds data backed up from a previous version of TrafficDirector, the following message is displayed:
Setup has detected that some data was backed up from the previous Traffic Director installation. Would you like to restore the data (y/n)? [y]
Step 13 Enter Y to restore the data or N to ignore it.
The installation script unpackages the files, extracts them to the installation location you specified, then performs the installation.
When the installation is complete, the following messages are displayed:
The file /usr/CSCOtd/.traffdir.sh or .traffdir.cshrc contains the shell cmds required to set the environment for running TrafficDirector. The file /usr/CSCOtd/X/RMONmanager is the application resources file for TrafficDirector. You may want to modify this file in order to customize the application, for example, to change the screen background colors. Installation completed. To start traffic director from a shell command line, follow these steps: 1) Make sure your DISPLAY variable is set correctly, and X binaries are in your path 2) Issue the command: For csh: % (source /usr/CSCOtd/.traffdir.cshrc ; /usr/CSCOtd/bin/tdir)&
For sh or ksh: # (. /usr/CSCOtd/.traffdir.sh ; /usr/CSCOtd/bin/tdir)& (Do not forget the dot at the beginning followed by space)
Step 14 Enter the appropriate command to unmount the CD-ROM.
Step 15 Remove the TrafficDirector CD-ROM from the drive.
Step 16 Log out of the root user account.
To effectively use the TrafficDirector online help feature, you must install and configure a web browser on your system and create a link that points to the browser.
|
Caution Because the TrafficDirector installation is performed by the root user (and, therefore, the files are owned by root), you must make the changes while logged into the system as the root user. |
If you chose not to configure the web browser during the installation procedure, you can set up the link now.
Edit the .traffdir.cshrc or .traffdir.sh file and add a line similar to the following to point to the location of your web browser:
setenv HTMLBIN install_path
where install_path is the absolute path of the web browser executable.
For example, if your browser is installed in your home directory, your path would look similar to the following:
setenv HTMLBIN /home/netscape/netscape
To start the TrafficDirector application in the background, follow these steps:
Step 2 Enter the following command and press Enter:
%(source /usr/CSCOtd/.traffdir.cshrc;/usr/CSCOtd/bin/tdir)&
#(. /usr/CSCOtd/.traffdir.sh;/usr/CSCOtd/bin/tdir)&
The TrafficDirector main window is displayed (Figure 2-1).

Note For more comprehensive information, see Using the TrafficDirector Application. |
When you run the TrafficDirector application, it starts the dbchkd daemon that launches all daemons responsible for logging and reporting. At regular intervals, dbchkd verifies that all logging and reporting daemons are running, and if necessary, restarts daemons that are not running, thereby ensuring the integrity of logging and reporting.
If you need to shut down the TrafficDirector application, when you close the TrafficDirector main window (using File > Exit from the menu bar), a confirmation window is displayed, asking if you want to shut down all daemons.
Do one of the following:
You can disable the daemon shutdown message that is displayed when you shut down the TrafficDirector application (Do you want to shut down all daemons?).
To disable the message, follow these steps:
Step 2 Using a text editor, open the default.dvp file for editing.
Step 3 Locate the text string ok-to-shutdown-msg.
Step 4 Disable the display of the confirmation message by replacing the default value of Yes with No.
Step 5 Save the change.
|
Note Disabling this message does not impact logging or reporting. All daemons continue to run and logging and reporting are enabled. |
After you have installed the TrafficDirector application, verified that you can open it on your network management station, and configured a SQL server database for logging data for create trend reports, you must perform these additional tasks:
Step 2 Define the type of data to be monitored, including protocols, topologies, and views of network traffic.
Step 3 Establish how much data you want to capture for real-time monitoring, including any limits and associated actions.
Step 4 Configure alert messages and parameters so they are triggered when established limits are reached.
Step 5 Determine the content and appearance of printed statistical reports.
Step 6 If necessary, modify the default aging, baseline, and utilization parameters.
For more information about these tasks, see Using the TrafficDirector Application.
To remove the TrafficDirector application, follow these steps:
Step 2 Click Yes to shut down all TrafficDirector-related daemons.
Step 3 Log into the system as the root user.
Step 4 Insert the TrafficDirector CD-ROM into a CD-ROM drive.
Step 5 Make sure that the CD-ROM is mounted.
For more information, see "Mounting and Unmounting a CD-ROM."
Step 6 To change directories, enter the following command and press Enter:
cd /cdrom/cdrom0/disk1
Step 7 To run the uninstallation script, enter the following command and press Enter:
./uninstall.sh
Step 8 To continue with the uninstallation at the following confirmation prompt, enter
Y and press Enter, or enter N and press Enter to cancel the uninstallation.
CSCOtd Delete the tdir packages (y/n)? [y]
Step 9 The uninstallation procedure continues.
To reinstall the TrafficDirector application on AIX platforms, you must kill the resolver process before starting the reinstallation.
To kill the resolver process, follow these steps:
ps -ef | grep resolver
Information similar to the following is displayed:
smith 20144 22608 1 14:49:43 pts/1 0:00 grep resolver
The first number displayed (in this example, 20144) is the resolver process ID.
Step 2 To kill the resolver process, enter the following command and press Enter:
kill 20144
After killing the resolver process, complete the installation by following the procedures in the "Installing the TrafficDirector Application" section.
