Chapter1 Command-Line Interface
Understanding Command Modes
When you start a session on the Catalyst4500 series switch, you begin in user mode, often called EXEC
mode. Only a limited subset of the commands are available in EXEC mode. In order to have access to
all commands, you must enter privileged EXEC mode. Normally, you must enter a password to enter
privileged EXEC mode. From privileged EXEC mode, you can enter any EXEC command or enter global
configuration mode. Most EXEC commands are one-time commands, such as show commands, which
show the current status of a given item, and clear commands, which clear counters or interfaces. The
EXEC commands are not saved across reboots of the Catalyst4500 series switch.
The configuration modes provide a way for you to make changes to the running configuration. When you
save changes to the configuration, the changes remain intact when the Catalyst 4500 series switch
reboots. From global configuration mode, you can enter interface configuration mode, subinterface
configuration mode, and other protocol-specific modes.
ROM-monitor mode is a separate mode used when the Catalyst4500 series switch cannot boot properly.
If your Catalyst4500 series switch or access server does not find a valid system image when it is booting,
or if its configuration file is corrupted at startup, the system might enter ROM-monitor mode.
Table1-3 provides a summary of the main command modes.
