The show ib-path command displays the entire IB path, including the individual links that comprise the overall IB path. A typical IB path might contain the following items:
A link from a host server's HCA to an IB switch that is located between the host and the fabric.
A link from the IB switch to the fabric.
One or more links within each fabric that correspond to links between the hardware on the fabric board.
At each of these individual links, performance statistics and error counters are tracked and displayed in a table so that you can check the functionality of the IB path at different points. In the CLI, use the following syntax for the show ib-path stats command:
show ib-path stats physical-server1 physical-server2
Additional information about the statistics includes the following:
Statistics are not polled or refreshed at regular intervals, so you must explicitly issue the command every time you want to display an updated set of statistics.
You can reset statistics to zero to allow them to accumulate by using the optional –clear option.
Statistics are reset if the fabric board is reset. For example, the fabric is power cycled.
