Step 2 Stop or restart the servers.
- To stop the Analyzer servers, run the stop.All shell script:
# /opt/CSCOnfa/stop.All
- To restart the Analyzer servers, run the start.All shell script:
# /opt/CSCOnfa/start.All
To start the user interface, enter the appropriate command:
Solaris: # /opt/CSCOnfa/NFADisplay/bin/start.Display
HPUX: # /opt/CSCOnfa/NFADisplay/bin/start.Display
Windows NT: C:\NFADisplay\bin>startPC_Display
This section describes new features for Release 3.0 of the Analyzer.
- NetFlow FlowCollector Control---You can use the Analyzer to create, modify, and delete collections on remote machines running Release 3.0 of the FlowCollector.
Note The Analyzer works best if you run the FlowCollector in Release 3.0 mode. The FlowCollector's default mode is set to NFC20_COMPATIBLE_MODE yes. To run the FlowCollector in Release 3.0 mode, stop the FlowCollector, change the setting in the nf.resources file to NFC20_COMPATIBLE_MODE no, and restart the FlowCollector.
Note To avoid having to log on to a FlowCollector each time you want to modify a NetFlow configuration, run the FlowCollector gateway program (NFCGW) with the PROGRAMFLAGS switch set to -i (dash, lowercase i).
- Traffic matrix statistics (TMS) control---You can use the Analyzer to create and delete TMS data collections on UtilityServers. This capability requires that routers be running IOS Release 12.0(6)T or 12.0(5)S.
- Router configuraton for data export---You can use the Analyzer to set up collection parameters for exporting NetFlow or TMS data from routers.
- On-router aggregation schemes---You can use the Analyzer to set up routers to collect and display data for five new on-router aggregation schemes. These on-router aggregation schemes require that routers have DNS names and be running IOS Release 12.0(3)T or Release 12.0(6)S.
- Online help system---You can use Netscape Version 4.5 or Internet Explorer Version 5 as the Web browser for viewing the Analyzer help system.
Release 3.0(2) of the Analyzer has these new features:
- Support---The Analyzer is supported on HPUX Version 11.0.
- Compressed data files---The Analyzer can read compressed files that the FlowCollector created. NetFlow collection control can also set or unset compression.
- Traffic Matrix Statistics (TMS) histogram charts---Histogram charts can be generated for traffic matrix statistics data.
Following are suggestions for using the Analyzer:
- To run the Display module from a Windows NT platform, use this procedure:
(a) Set protections on the NFADisplay directory and all of its subdirectories by entering the following command at the root level:
# chmod -R 777 /opt/CSCOnfa/NFADisplay
(b) Copy the /opt/CSCOnfa/NFADisplay directory and all of its subdirectories and files to the target directory on your PC.
(c) Change directory (cd) to NFADisplay/bin.
(d) Enter startPC_Display.bat
- Make sure one UtilityServer at a time is collecting TMS data from a given router.
- If you are working in the AS Drill Down window and the Search window, you must use the DetailASMatrix aggregation scheme.
- Use the Router Configuration option on the Tools menu to configure TMS data collection, and then use the TMS Collection Control window to start a collection on the UtilityServer. The router configuration process recognizes only those routers that have DNS entries.
- If the UtilityServer is stopped and then restarted, TMS collections are not resumed.
- To enable the router configuration process to reread the router configuration files, restart the Display module.
- To navigate in the router-based aggregations table in the RouterConfig window, do the following:
- To advance to the next cell, press Tab.
- To advance to the next row, press Return.
- To display the Contents, Index, and Search functions of online Help, enable Java and Javscript in your browser. In Netscape, use the Advanced option under Edit > Preferences.
This section describes known bugs and restrictions for Release 3.0 of the Analyzer.
- The UtilityServer might fail to start. When this happens, wait 3 to 4 minutes and try to restart the UtilityServer by executing the start.UtilityServer script.
- If you cannot invoke the Analyzer Help system while running under Windows NT, do the following:
(a) Open Windows Explorer.
(b) Find the script startPC_Display in the NFADisplay\bin directory.
(c) Click the right mouse button over the script and select Edit. An editor window appears with the script in it.
(d) Move the mouse over the icon that corresponds to your Internet browser.
(e) Click the right mouse button and select Properties.
(f) Go to the field labeled Target, press the right mouse button, and select Copy.
(g) Go to the editor window. Place the cursor after the -browser command line option.
(h) Delete the argument that follows the -browser command line option.
(i) Select Edit and Paste. This places the correct browser path\program name in your script. Make sure that the path\program name is enclosed within quotes.
(j) Select File and Save.
(k) Run the script.
- If a window is blank or all blue/grey, resize the window or minimize the window and then restore it.
- If the Display module runs out of memory, an Out of Memory message appears on the terminal window from which the Analyzer Help system was invoked. If that happens, edit the start_Display file and place the -ss, -oss, and -mx options before the Java call, as shown below:
/opt/CSCOnfa/NFADisplay/RunTimeJava/bin/java -ss2m -oss2m -mx32m -cp ...
- RouterConfig cannot configure routers that prompt for a user name or contain an "enable secret" password.
- TMS collections are not resumed if the UtilityServer is stopped and then restarted.
- If you cannot change the TMS internal/external setting for the router interfaces, the IOS software on the selected router does not support that functionality.
- If you delete a TMS collection, you must wait approximately 15 seconds before starting a new collection on that router. Otherwise, a router in use error message is displayed.
- Although the Display module can run on a UNIX platform and can send output to an X server running on a PC using an X windows emulator, this configuration is not supported.
- The Display module does not run under OpenWindows unless OpenWindows is installed with the motif libraries.
- During the installation of NDA on HPUX, after you answer y to Do you want to start the servers?, ignore the syntax error message regarding the following:
/opt/CSCOnfa/NFAUtility/bin/start.UtilityServer [90]:
Syntax error
The Analyzer servers were successfully started.
The following bugs and restrictions from Release 3.0 are corrected in Release 3.0(2) of the Analyzer:
- The AnalyzerDisplay generated pie charts, bar graphs, and histograms for columns other than the selected columns for the Call Record aggregation scheme.
- When you requested that the Analyzer display traffix matrix statistics data from a directory that contained zero length files, a Get Data error message occurred.
