Using CLI Command Modes
Switches in the Cisco Nexus 5000 Series have two main command modes: user EXEC mode and
configuration mode. The commands available to you depend on the mode you are in. To obtain a list of
available commands in either mode, type a question mark (?) at the system prompt.
Table 2-1 lists and describes the two commonly used modes, how to enter the modes, and the resulting
system prompts. The system prompt helps you identify which mode you are in and the commands that
are available to you in that mode.
Command Purpose
ssh {hostname | ip_addr}
Makes an SSH connection from your host to the switch that you
want to access.

mode are generally

system resets.

mode command.
switch#
Configuration mode Enables you to configure
features that affect the
system as a whole.

mode are saved
