Clearing Configured fcanalyzer Information

Use the clear fcanalyzer command to clear the entire list of configured hosts. Note that the existing
connections are not terminated.

Displaying Configured Hosts

Use the show fcanalyzer command to display the list of hosts configured for a remote capture. See
Example
Example 58-1 Displays Configured Hosts
switch# show fcanalyzer
PassiveClient = 10.21.0.3
PassiveClient = 10.21.0.3
ActiveClient = 10.21.0.3, DEFAULT
Note The DEFAULT in the ActiveClient line indicates that the default port is used.

Displaying Captured Frames

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 only want to view Exchange Link Protocol (ELP) request
frames. This feature only limits the captured view—it does not affect the captured or the saved frames.
Procedures to specify, use, and save display filters are already documented in the Ethereal web site
(http://www.wireshark.org). Some examples of how you can use this feature are as follows:
