Testing Capabilities of the
IBTrainer
This section lists the key test capabilities of the IBTrainer. They are
structured along the following ISO/OSI layers as described in the
InfiniBand specification:
• Physical layer
• Link layer
• Network layer
• Transport layer
“Testing Capabilities in Terms of Concrete Tests” on page 31 gives a list
of the capabilities of the IBTrainer as defined by the Compliance
Interoperability Work Group (CIWG).
Physical Layer
The IBTrainer is not capable of testing the physical layer.
As described in the IB specification, the physical layer is the physical
connection between two devices. Thus, there are certain aspects of
InfiniBand connections that the IBTrainer does not test:
• Signal level, quality, and frequency
• 8B/10B encoding and decoding
The IBTrainer makes comma and skip insertions according to the
InfiniBand specification (1 comma and 3 skip symbols occur every 4352
to 4608 clocks). The number of skips cannot be influenced. The
IBTrainer generates idle packets as described in the InfiniBand
specification.
You can, however, insert running disparity errors into the data stream.
Running disparity errors can be created only within packets. This is
controlled by the packet behavior setting. Such packet behavior is
controlled by the packet property setting.
