Appendix C
Summary of Libraries
622Vu Advisor is shipped with several cell libraries that are designed to help
with specific types of ATM analysis, as detailed in this appendix. You can use
these libraries for your own purposes, or modify them as needed.
Table 13. Libraries Distributed with the System
Library Name Description
cb_std.lib Contains one sample script and samples of filtersets used to capture UNI,
ILMI, CLP, OAM, etc., traffic. Good as a base to edit and customize.
sample1.lib Contains two sample scripts:
One for full bandwidth split between VCIs 1 – A, transmitted in raw cell
mode (not as part of PDUs), with ten cells repeated 13,000 times. This
results in 130,000 cells, which fills the 8 MB of capture RAM on
certain devices.
The other is designed to test Bad HEC counts, and sends three good HEC
cells then three bad. It repeats this process 1,000 times for a total of
6,000 cells.
Includes samples of filtersets that you can modify, showing all the
combinations of options (wrap, no-wrap, include idle cells, don’t include
idle cells, etc.).
sample2.lib Contains sample scripts you can customize, including:
•
One for full bandwidth to send on VCIs 6–E, to test a switch’s ability
to forward a full-bandwidth pipe to ten VCIs that will each be 10%
loaded.
•
Some UNI 3.1 traffic that you can retransmit on any VPI/VCI of your
choosing.
Includes some basic (non-wrapping) filtersets for simplified capture of idle
cells or specific VCCs.
sample3.lib Provides bandwidth scripts you can use to load ATM networks at various
rates (1, 5, 10 – 100%), independent of the interface type. These scripts are
all sent out on VCC 99/99, but you can edit the sequence to change this, as
necessary, by going in at the transmit sequence level (see Chapter 9).
Includes a buffered filterset that captures VCC 99/99 and displays the
percent-of-bandwidth captured. This is useful for blasting through switches
and verifying sustained throughput at different levels.
