Channel Filters
Defining Filters and Triggers
Use the Channel filters to specify different wireless channels to include
as part of this filter. Acceptable values range from 1-161. You can enter
either multiple values separated by commas or a single range separated
by a hyphen. For example, you could enter a range like this:
1-12
Alternatively, you could enter multiple individual values like this:
5,7,12,149
Speed Filters
Use the Speed filters to specify different wireless traffic speeds (in
Mbps) to include as part of this filter. Packets matching one of the
specified speeds are included as part of the filter.
You can enter either multiple speeds separated by commas or a single
speed range separated by a hyphen. For example, you could enter a
range like this:
1-10
Alternatively, you could enter multiple individual values like this:
48,54
Setting Filter Options in the Buffer Tab
Set options for the capture buffer on the Buffer tab. (These settings are
used only if the filter is being used as a capture filter.) For a description
of the capture buffer settings, refer to Capture Buffer on page 124.
Working with Display Filters
A display filter allows you to filter out unwanted packets when you
display the contents of a capture buffer or trace file in the postcapture
window. The profile defined for a capture filter can also be used for
filtering out packets from the postcapture Display by using the Display
> Select Filter command – the dialog box that appears will display all
defined Capture Filter profiles under their own entry. See Selecting
Filters / Combining Multiple Filters on page 174 for details.
The procedure for defining a display filter is identical to the procedure
for a capture filter.
