[mst instance] [memory] [config]
Syntax Description
Defaults By default, this command displays the output for technical-support-related show commands. Use
keywords to specify the type of information to be displayed. If you do not specify any parameters, the
system displays all configuration, memory, module, port, instance, and VLAN data.
Command Types Switch command.
Command Modes Normal.
Usage Guidelines
Caution Avoid running multiple show tech-support commands on a switch or multiple switches on the network
segment. Doing so may cause spanning tree instability.
The show tech-support command may time out if the configuration file output takes longer to display
than the configured session timeout time. If this happens, enter a set logout timeout value of 0 to disable
automatic disconnection of idle sessions or enter a longer timeout value.
The show tech-support command output is continuous; it does not display one screen at a time. To
interrupt the output, press Ctrl-C.
If you specify the config keyword, the show tech-support command displays the output of these
commands:
• show config
• show flash
• show log
