Reference Guide

Beneath CONFIGURATION mode are submodes that apply to interfaces, protocols, and features. The following example
shows the submode command structure. Two sub-CONFIGURATION modes are important when configuring the chassis
for the first time:
• INTERFACE submode is the mode in which you configure Layer 2 and Layer 3 protocols and IP services specific
to an interface. An interface can be physical (Management interface, 1 Gigabit Ethernet, or 10 Gigabit Ethernet,
or synchronous optical network technologies [SONET]) or logical (Loopback, Null, port channel, or virtual local
area network [VLAN]).
• LINE submode is the mode in which you to configure the console and virtual terminal lines.
NOTE: At any time, entering a question mark (?) displays the available command options. For example, when you
are in CONFIGURATION mode, entering the question mark first lists all available commands, including the possible
submodes.
The CLI modes are:
Navigating CLI Modes
The FTOS prompt changes to indicate the CLI mode.
The following table lists the CLI mode, its prompt, and information about how to access and exit the CLI mode. Move
linearly through the command modes, except for the end command which takes you directly to EXEC Privilege mode
and the exit command which moves you up one command mode level.
NOTE: Sub-CONFIGURATION modes all have the letters “conf” in the prompt with more modifiers to identify the
mode and slot/port information.
Table 1. FTOS Command Modes
CLI Command Mode Prompt Access Command
EXEC
FTOS>
Access the router through the
console or Telnet.
EXEC Privilege
FTOS#
• From EXEC mode, enter the
enable command.
• From any other mode, use the
end command.
CONFIGURATION
FTOS(conf)#
• From EXEC privilege mode,
enter the configure
command.
• From every mode except
EXEC and EXEC Privilege,
enter the exit command.
NOTE: Access all of the following
modes from CONFIGURATION
