Command mode access is determined by access permission levels and password
protection.
If no password is set, you can enter ACLI in User EXEC mode and use enable to move to
the next level, Privileged EXEC mode.
However, if you have read-only access, you cannot progress beyond User EXEC mode, the
default command mode.
If you have read-write access you can progress from the default mode through all of the
available command modes.
User EXEC mode is the default ACLI command mode and the initial access mode. Also known
as exec mode, it is the most restrictive ACLI mode and has few commands available; for
example, ping and logoff. User EXEC commands are available from the other modes.
Privileged EXEC mode is an unrestricted command mode that can display all switch settings,
and, if you are logged on with write access, you can access all configuration modes and
commands that affect switch operation from this mode. In Privileged EXEC mode, also known
as privExec mode, you can perform basic switch level management tasks such as downloading
software images, setting passwords, and starting the switch. Privileged EXEC commands are
also available in Global and Interface configuration modes.
Global Configuration mode, also known as config mode, provides commands used to set and
display general switch configurations such as IP address, Simple Network Management
Protocol (SNMP) parameters, Telnet access, and Virtual Local Area Networks (VLAN).
From the Global Configuration mode, access the Router Configuration Mode by entering one
of the following commands:
• router rip
• router ospf
• router vrrp
Interface Configuration mode, also known as config-if mode, provides commands used to
configure parameters for each port or VLAN such as speed, duplex mode, and rate limiting.
With sufficient permission, you can use the rules in the following table to move between the
command modes.
