Hardware Control and Troubleshooting
3 Hardware Control and Troubleshooting
The operating system command-line interface (CLI) includes commands
that display hardware configuration and status information, allow hardware
troubleshooting, and provide hardware control and recovery. You enter all
commands through the management port or the console port on the active
controller card. When the system is powered on or reloaded, the active
controller card is in slot 7.
The mode in which you enter a command is as follows:
• Enter show commands in any mode.
• Enter clear and reload commands in exec mode.
• Enter the card command and the port command for any type of port or
channel in global configuration mode.
• Enter the loopback and shutdown commands in the configuration mode
for the port or channel.
3.1 Hardware Status
The CLI commands listed in Table 30 display status information, such as
power, temperature, ports, and alarms for the fan tray and individual cards
and ports. Required characters and keywords are shown in bold; arguments
for which you must supply a value are shown in italics. You can enter show
commands in any mode.
For descriptions of the output for any CLI command, see related documentation
