9.4 Expanding & Collapsing Traffic

Management Datagrams and Transport Functions can
be "opened" to reveal their constituent packets by
double-clicking the first cell in of a Transport Function
or MAD or by clicking once on the small arrow on that same cell. The
packets will then display below the message. The following screenshot
shows an example of a message and its packets.

9.5 MAD Formats

Management datagrams are displayed as a separate decode level - this fact
needs some explanation. Because a MAD is an unreliable datagram
composed of a single packet, CATC could have elected to display MADs as
a decode within the packet level or as a decode within the Transport
Function level. CATC chose to display MADs as their own level in order
to present MAD data more clearly.

9.6 MAD, SA and SRP Decoder Script Files

IBTracer uses decoder script files to decode MADs, Subnet Administration
transactions, and SCSI RDMA protocol transactions. Decoder script files
are automatically read when the IBTracer software is started. Thereafter,
when MAD, SA, or SRP traffic is encountered, the Analyzer software is
able to decode the traffic.

Decoder script files are shipped with IBTracer and located in the
IBTracer\Scripts directory.

Users may edit the decoder scripts or create new ones to decode vendor-and
application-specific classes and attributes.

NOTE: Details about how to edit CATC decoder scripts or write your own
are provided in the manual CATC Scripting Language Reference Manual
for IBTracer and MAD Decoders
available from CATC.
