Multiple Configuration Users
When a user enters CONFIGURATION mode and another user(s) is already in that configuration
mode, FTOS generates an alert warning message similar to
Figure 2-2 :
Figure 2-2. Configuration Mode User Alert
When another user enters CONFIGURATION mode, FTOS sends a message similar to the following,
(the user in this case is “admin” on vty2):
% Warning: User “admin” on line vty2 “172.16.1.210” is in configuration
Navigating the Command Line Interface
The command line interface (CLI) prompt displayed by FTOS is comprised of:
• “hostname”— the initial part of the prompt, “FTOS” by default. You can change it with the
hostname command, as described in hostname .
• The second part of the prompt, reflecting the current CLI mode, is shown in Table 2-1 .
The CLI prompt changes as you move up and down the levels of the command structure.
Table 2-1 lists the prompts and their corresponding command levels, called modes . Starting with
CONFIGURATION mode, the command prompt adds modifiers to further identify the mode. The
command modes are explained in
Command Modes .
