Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

Listing the Commands Used with Each Command Mode
You can display the commands available in any command mode by typing a question mark (?) at the switch
prompt.
CLI Command Hierarchy
CLI commands are organized hierarchically, with commands that perform similar functions grouped under
the same level. For example, all commands that display information about the system, configuration, or
hardware are grouped under the show command, and all commands that allow you to configure the switch
are grouped under the configure terminal command.
To execute a command, you enter the command by starting at the top level of the hierarchy. For example, to
configure an interface, use the config terminal command. Once you are in configuration mode, enter the
interface command. When you are in the interface submode, you can query the available commands.
The following example shows how to query the available command in the interface submode:
switch# configure terminal
switch(config)# interface ethernet 1/1
switch(config-if)# ?
bandwidth Set bandwidth informational parameter
cdp Configure CDP interface parameters
channel-group Add to/remove from a port-channel

EXEC Mode Commands
When you start a session on the switch, you begin in EXEC mode. From EXEC mode, you can enter
configuration mode. Most of the EXEC commands are one-time commands, such as show commands, which
display the current configuration status.
