N Port Tuning Configuration Physical Example
Figure 41-3
provides a sample logical setup in which the virtual N ports are created on ports that are not
a part of the FCIP link for which the throughput and latency is measured.

Logical Example of N Port Tuning for a FCIP Link
Data Pattern
By default, an all-zero pattern is used as the pattern for data generated by the virtual N ports. You can
optionally specify a file as the data pattern to be generated by selecting a data pattern file from one of
three locations: the bootflash: directory, the volatile: directory, or the slot0: directory. This option is
especially useful when testing compression over FCIP links. You can also use Canterbury corpus or
artificial corpus files for benchmarking purposes.
License Prerequisites
To use the SET, you need to obtain the SAN_EXTN_OVER_IP license (see
Chapter 3, “Obtaining and
Installing Licenses”
).
