Protocol Analyzer
Using Packet Capture Instances
356 5967–9446
To configure the capture buffer
1 Create a new instance, if necessary.
2 Select Settings➤Capture Buffer… from the base
window.
3 Indicate the type of capture buffer.
4 Specify the size of the buffer.
5 Indicate whether to slice packets.
When Protocol Analyzer captures packets, it stores them in the capture
buffer on the agent. You can specify the type of capture buffer, its size,
and whether to slice (truncate) packets.
The capture buffer configuration window contains the following fields.
See Also “To display Traffic Trend (packet match counts)” on page 396.
Circular Indicates whether the buffer wraps around when full; that is, when the
buffer is completely filled, packet capture continues, and older data is
overwritten. If Circular is not checked, packet capture stops
automatically when the buffer is full.
KBytes Indicates how large to make the capture buffer, in kilobytes.
Note that you can specify a buffer size of 0 kilobytes. This setting is
useful when you want to know how many packets match the current
filter but don’t need to view the packet contents. For further
information, refer to page 396.
Truncate After Specifies whether to truncate (slice) packets. To keep all data for each
packet, choose Don’t Truncate. Otherwise, choose the number of bytes
to keep for each packet.
