FTOS Configuration Guide for the C-Series - Force10 Networks

When creating a trace list, the sequence of the filters is important. You have a choice of assigning sequence
numbers to the filters as you enter them, or FTOS assigns numbers in the order the filters were created. For
more information on sequence numbering, refer to Chapter 17, IP Access Control Lists, Prefix Lists, and
Route-maps, on page 333.
Configuration Task List for Trace lists
The following configuration steps include mandatory and optional steps.
• Creating a trace list on page 168 (mandatory)
• Applying trace lists on page 172 (mandatory)
For a complete listing of all commands related to trace lists, refer to the Security chapter in the FTOS
Command Reference.
Creating a trace list
Trace lists filter and log traffic based on source and destination IP addresses, IP host addresses, TCP
addresses, TCP host addresses, UDP addresses, and UDP host addresses. When configuring the Trace list
filters, include the count and bytes parameters so that any hits to that filter are logged.
Since traffic passes through the filter in the order of the filter’s sequence, you can configure the trace list by
first entering the TRACE LIST mode and then assigning a sequence number to the filter.
To create a filter for packets with a specified sequence number, use these commands in the following
sequence, starting in the CONFIGURATION mode:
