EXEC Mode
When you initially log in to the switch, by default, you are logged into the EXEC mode. This mode
allows you to view settings and to enter the EXEC Privilege mode to configure the device. While you
are in the EXEC mode, the
> prompt is displayed following the “hostname” prompt, as described
above. which is “FTOS” by default. You can change it with the
hostname
command. See the
command hostname . Each mode prompt is preceded by the hostname.
EXEC Privilege Mode
The enable command accesses the EXEC Privilege mode. If an administrator has configured an
“Enable” password, you will be prompted to enter it here.
The EXEC Privilege mode allows you to access all commands accessible in EXEC mode, plus other
commands, such as to clear ARP entries and IP addresses. In addition, you can access the
CONFIGURATION mode to configure interfaces, routes, and protocols on the switch. While you are
logged in to the EXEC Privilege mode, the
#
prompt is displayed.
CONFIGURATION Mode

configure
command to enter the CONFIGURATION mode and
configure routing protocols and access interfaces.

2. Enter the configure command. The prompt changes to include (conf).

be physical (for example, a Gigabit Ethernet port) or virtual (for example, the Null interface).

1. Verify that you are logged into the CONFIGURATION mode.
2. Enter the interface command followed by an interface type and interface number that is available
on the switch.
