User EXEC mode
The User EXEC mode (also referred to as exec mode) is the default CLI
command mode. User EXEC is the initial mode of access when you
first turn on a switch. User Exec mode provides a limited subset of CLI
commands, is the most restrictive CLI mode, and has few privileges.
Privileged EXEC mode
Use Privileged EXEC mode (also referred to as privExe mode) to
perform basic switch-level management tasks, such as downloading
software images, setting passwords, and booting the switch.
Global Configuration mode
Use Global Configuration mode (also referred to as config mode) to set
and display general configurations for the switch, such as IP address,
SNMP parameters, Telnet access, and VLANs.
Interface Configuration mode
Use Interface Configuration mode (also referred to as if-config mode) to
configure parameters, such as speed, duplex mode, and rate-limiting,
for each port or VLAN.
