and then when the ATM is proven to be reliable evaluate the same traffic with
the Advisor LAN to find existing LAN problems.
To use the Advisor LAN on your ATM 622 traffic you will need to do the
following steps:
1. Connect the ATM 622 undercradle to the network under test and capture
desired LAN traffic using any VCC filters desired. Filters can be used to
limit the amount of traffic to only the desired traffic, if no filters are used
then all LAN traffic running over AAL-5 is analyzed.
2. Save the captured traffic to a data file on the hard drive. This file can later be
opened by the ATM 622 application and additional post process filters
applied to reduce the amount of traffic if desired.
3. Start the Advisor LAN found under the Start menu. Use the Start | Agilent
Advisor | ATM Analysis | Off-Line LAN-ATM Expert path. This will open
the program with a default set of parameters. You can now import the ATM
622 file into this application. Select [File] then [Open (Load Data)]. You
will now see a list of all of the *.dat files that have been saved by the Advisor
LAN. As a part of the open window you should see an input box labeled
“Files of type”. You will need to click on the pull-down arrow and select the
file type identified as “*.cap”. This will now apply a file filter to only show
you the ATM 622 files and most likely the file list window will be blank.
You will need to use the directory navigator icon in the open box to move up
until the “Look in” box has the “Advisor” directory listed. Now select
“622Vu” then “Capture” and now you should see the ATM 622 files that
have been stored.
Note: If you change the default directory for the file save you will need to
change to that directory to do the import.
4. Once you have a list of the ATM 622 files you can select one file to open.
Click one time and wait for the import function to validate the file be verify
that you can open this file. You will see a “Created by:” box that lists the
application used to create the file if it can be imported along with a yellow
indicator. This yellow indicator lets you know that you have selected a file
that will need to be converted to the Advisor LAN format. Click on the
“Open” button to start the import function. NOTE: if the ATM file does not
have LAN traffic carried over AAL-5 the import will fail and you will see a
missing file notification.
5. Once you have imported the file you will be able to use the Advisor LAN
decode engine to decode the LAN traffic in detail. You can also let the
“Expert Analyzer” look through the traffic by switching to the Expert screen.
From the “Run” pull-down select “Run From Buffer” to start the expert and
select the range of frames to evaluate. You will then be able to watch the
