capture only HTTP traffic, specify port 80.
NOT - Tap On to invert your filter selections. If you have select-
ed multiple filters, the NOT function will give the inverse of
the aggregated filter results. For example, if you have set up a
filter to capture traffic to and from 10.250.0.70 on port 80, and
you select NOT, all traffic will be captured except traffic to and
from 10.250.0.70 on port 80.

ter on if you have specified an IP address in the above IP ad-

Set the File Size Limit and the Frame Slice Size to limit /
control the amount of data that will be captured.
File Size Limit - The analyzer can save up to 2 GB of traffic in
each capture file. You can select a smaller file size if desired.
The capture will stop before exceeding the selected file size.
Frame Slice Size - The Frame Slice Size control limits how much
of each packet is captured. If you select 64 B, the first 64 bytes
of each packet will be captured. This is useful when you are in-
terested in the packet's header, but you don't need to see all
the payload data. You can also use slice size to control the
amount of data captured, and thereby reduce the possibility of
dropped frames.
Enable AutoTest Capture to cause the analyzer to capture
5
traffic automatically when AutoTest is run.
