Chapter 68 Configuring Wireshark
How to Configure Wireshark
Defining, Modifying, or Deleting a Capture Point
Although listed in sequence, the steps to specify values for the options can be executed in any order. You
can also specify them in one, two, or several lines. Except for attachment points, which can be multiple,
you can replace any value with a more recent value by redefining the same option, in the following order:
Step 1
Define the name that identifies the capture point.
Step 2
Specify the attachment point with which the capture point is associated.
Multiple attachment points can be specified. Range support is also available both for adding and
removing attachment points.
Step 3
Define the core system filter, defined either explicitly, through ACL or through a class map.
Step 4
Specify the session limit (in seconds or packets captured).
Step 5
Specify the packet segment length to be retained by Wireshark.
Step 6
Specify the file association, if the capture point intends to capture packets rather than merely display
them.
Step 7
Specify the size of the memory buffer used by Wireshark to handle traffic bursts.
To filter the capture point, use the following commands:
File size
No limit
Ring file storage
No
Buffer storage mode
Linear
