Command History
Usage Guidelines 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.
Examples The following example configures the data pattern file for an N port.
switch# san-ext-tuner
switch(san-ext)# nWWN 10:00:00:00:00:00:00:00
switch(san-ext)# nport pwwn 12:00:00:00:00:00:00:56 vsan 13 interface gigabitethernet
