config packet line
[
<line_number>
] configures packet capturing on the specified
line.
<line_number>
specifies the number of the physical line. You can enter the line
number on the command line or have the script prompt you for it.
The
config packet line
command prompts you for the media type, slot number,
and connector number, so you should gather this information before you begin.
After you enter this information, the script displays available memory and the
maximum packet save size.
As it runs, the script displays the current values of the following items and asks
you to either press [Return] to confirm or enter a new value:
• Capture buffer size
• Packet save size
• Capture direction options: receive, transmit, or both
• Receive trigger options (when to stop capturing packets): when buffer is full,
when filter 1 is matched, when filter 2 is matched, or no filter
• Transmit trigger options (when to stop capturing packets): when buffer is full,
when filter 1 is matched, when filter 2 is matched, or no filter
• Receive filter configuration: Type and Reference options
• Transmit filter configuration: Type and Reference options
For information about all these options, see Appendix B.

command:
