Defaults All zero pattern. Command Modes SAN extension N port configuration submode. Command History Release 2.0(x) Modification This command was introduced. 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 1/2 switch(san-ext-nport)# data-pattern-file bootflash://DataPatternFile Related Commands Command nport pwwn san-ext-tuner show san-ext-tuner Description Configures SAN extension tuner N port pWWNs.
