Customizing show tech Command Output

Use the copy show tech command to customize the detailed switch information displayed with the show tech command to suit your troubleshooting needs.

To customize the information displayed with the show tech command:

1.Determine the information that you want to gather to troubleshoot a problem in switch operation.

2.Enter the copy show tech command to specify the data files that contain the information you want to view.

Syntax: copy <source> show- tech

Specifies the operational and configuration data from one or more source files to be displayed by the show tech command. Enter the command once for each data file that you want to include in the display.

Default: Displays data from all source files, where <source> can be any one of the following values:

command-output “< command >”

Includes the output of a specified command in show-techcommand output. Enter the command name between double-quotation marks; for example, copy “show system” show-tech.

crash-data [slot-id master]:

Includes the crash data from all management and interface modules in show tech command output.

To limit the amount of crash data displayed, specify an installed module or management modules, where: slot-id: Includes the crash data from an installed module. Valid slot IDs are the letters a through h.

master: Includes the crash data from both management modules.
