82 CLI Basics
CLI command modes
Most CLI commands are available only under a certain command mode.
The Ethernet Routing Switch 2500 Series 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 Routing Switch 2500 Series. 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 Routing Switch 2500
Series. 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 Routing Switch 2500 Series.
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.
The Interface Configuration commands allow you to configure parameters
for each port, such as speed and duplex mode. The Interface Configuration
mode is also referred to as config-if mode.
Figure 23 "CLI command mode hierarchy" (page 83) provides an illustration
of the hierarchy of Ethernet Routing Switch 2500 Series CLI command
modes.
