Table 5-1	diag Command Reference (continued)
Command		Description
tftp		Specifies that the source of the diagnostic image is a TFTP
		server. This keyword must be followed by the source-path.
		Also see the dl-timeout-plusoption.
flash		Specifies that the source of the diagnostic image is a Flash
		memory card. This keyword must be followed by the
		source-path.
source-path		Path to the diagnostic image. The name of the image file is
		c12k-fdiagsbflc-mz.120-25.S, where 120-25.S
		corresponds to Cisco IOS Release 12.0(25)S. For Flash
		cards, the source path would typically be
		slot0:c12k-fdiagsbflc-mz.120-25.Sor
		slot1:c12k-fdiagsbflc-mz.120-25.S. The TFTP source
		path would typically be
		tftp://tftp_server_ip_address/my_directory/c12k-fdiagsbf
		lc-mz.120-25.S. This option is available and required for
		line card testing only.
halt		(Optional) Stops the field diagnostic testing on the line
		card. This option is only available for line cards and RPs.
previous		(Optional) Displays previous test results (if any) for the
		card. This option is only available for line cards and RPs.
verbose		(Optional) Enables progress and error messages to be
		displayed on the console. By default, only the minimum
		status messages are displayed on the console, along with
		the final result. Due to the comprehensive nature of testing,
		testing without the verbose option will result in up to a
		15-minute delay before any results are displayed. Cisco
		recommends that the verbose option be specified and
		results captured when communicating with Cisco TAC.
