Creating Display Filters
You can selectively view captured frames by using the display filters feature. For example, instead of
viewing all the frames from a capture, you may want to view only ELP request frames. This feature limits
the captured view only—it does not affect the captured or the saved frames. Procedures to specify, use,
and save display filters are already documented at the following website under MDS 9000 Family
software: http://www.cisco.com/kobayashi/sw-center/sw-stornet.shtml. Click Cisco MDS 9000 Family
Port Analyzer Adapter to view the filters. The following list includes examples of ways to use this
feature:
