CLI command modes
Most CLI commands are available only under a certain command mode. The
Ethernet Switch 325/425 has the following four command modes:
• User EXEC
• Privileged EXEC
• Global Configuration
• Interface Configuration
The User EXEC mode is the default mode; it is also referred to as exec. This
command mode is the initial mode of access on powering-up the Ethernet Switch
325/425. In this command mode, the user can access only a subset of the total CLI
commands; however, the commands in this mode are available while the user is in
any of the other four modes. The commands in this mode are those you would
generally need, such as
ping
and
logout
.
Commands in the Privileged EXEC mode are available to all other modes but the
User EXEC mode. The commands in this mode allow you to perform basic
switch-level management tasks, such as downloading the software image, setting
passwords, and booting the Ethernet Switch 325/425. The Privileged EXEC mode
is also referred to as privExec mode.
The Global Configuration mode and the Interface Configuration mode allow you
to change the configuration of the Ethernet Switch 325/425. Changes made in
these command modes are immediately applied to the switch configuration and
saved to NVRAM.
The Global Configuration commands allow you to set and display general
configurations for the switch, such as the IP address, SNMP parameters, the
Telnet access, and VLANs. The Global Configuration mode is also referred to as
config mode.
