EXEC Mode

When you initially log in to the switch, by default, you are logged in to EXEC mode. This mode allows you

to view settings and enter EXEC Privilege mode, which is used to configure the device.

When you are in EXEC mode, the > prompt is displayed following the host name prompt, which is “FTOS”

by default. You can change the host name prompt using the hostname command.

NOTE: Each mode prompt is preceded by the host name.

EXEC Privilege Mode

The enable command accesses EXEC Privilege mode. If an administrator has configured an “Enable”

password, you are prompted to enter it.

EXEC Privilege mode allows you to access all the commands accessible in EXEC mode, plus other

commands, such as to clear address resolution protocol (ARP) entries and IP addresses. In addition, you

can access CONFIGURATION mode to configure interfaces, routes and protocols on the switch. While

you are logged in to EXEC Privilege mode, the # prompt is displayed.

CONFIGURATION Mode

In EXEC Privilege mode, use the configure command to enter CONFIGURATION mode and configure

routing protocols and access interfaces.

To enter CONFIGURATION mode:

1. Verify that you are logged in to EXEC Privilege mode.

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

From this mode, you can enter INTERFACE mode by using the interface command.

INTERFACE Mode

You must use INTERFACE mode to configure interfaces or IP services on those interfaces. An interface

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

To enter INTERFACE mode:

1. Verify that you are logged in to CONFIGURATION mode.

2. Enter the interface command with an interface type and slot/port numbers.

The prompt changes, as listed below, to include the designated interface and slot/port numbers.

NOTE: On the S5000, the valid slot numbers are the supported stack-unit numbers (0 to 11). The

valid port numbers for each interface type are listed below.
