Note:
When capturing PM traces, you need the ability to filter the PM primitives so you can find
commands quicker.
Filtering Direction
You can select items for filtering in a single direction or both directions by checking the
corresponding Port. By default, all ports are enabled. Uncheck the port check boxes for
ports not to include in the filter.
Filter Idle
Depending on the Filter Type (Hide/Show), Idle packets in the Sample Viewer are shown
or hidden.
Save Filter Setup
After you have set up a Filter configuration, you can save it as an SAS Filter file ( *sfl ) or
SATA Filter file ( *.tfl ) by clicking Save . You can then use it on a different capture by clicking
Load in the Filter dialog.
Filter Logic
After you have set up Filter options, you can set filter logic to And Related Items to apply
"AND" logic on related selected options (for example, SCSI commands and SAS Addresses)
or
OR to apply "OR" logic on all selected options.
Filter only applies to entities in a trace. When you choose SCSI command AND SSP frame,
for instance, Filter affects all entities in the trace that are SCSI commands, AND are SSP
frames. Any SCSI commands that are NOT SSP frames, will not, in this case, be filtered.
If you choose OR , Filter affects all entities that are SCSI commands, as well as all SSP
frames.
The AND operator is only applicable for some cases, such as:

A SCSI command AND a Tag.

A SCSI command AND a source/destination address.
For example, when you choose a SCSI command AND a tag = 0x1, you will filter all entities
on a trace that are SCSI commands that have tags equal to "0x1" in that SCSI command.
As a general rule, it is not possible to apply AND to two packet types (frames, commands,
primitives, training sequences or bus conditions). It only works when you apply AND to
one packet type with other items such as source/Destination Addresses, TAG, Task
attribute.
Multilevel Filtering in SAS
You can set up a filter in a sequential steps by Multi level filtering . In each level, you can
select specific items to “AND” to the previous level. The results of all levels show in views
(see
following screen captures).
