Configuring the System
Changes to system configuration can only be made from the global configuration mode and its
sub-modes, except when working with configuration files or reloading defaults. This is done in
Privileged Exec mode. The following steps outline the sequence.
1. Raise privilege level to 15.
2. Enter global configuration mode.
3. Input appropriate configuration commands. Optionally, enter sub-modes and input appropriate
commands there.
4. Exit global configuration mode.
5. Verify configuration.
6. Save configuration to flash.
Configuration Example
In this example, the hostname and VLAN 1 IP address is configured, verified, and saved. This
example assumes the session is initially unprivileged.
1. Raise privilege level: > enable
Password: ***
2. Enter global configuration mode: # configure terminal
3. Input configuration commands. The IP address is set from within the
! VLAN interface submode:
(config)# hostname my-device
my-device(config)# interface vlan 1
my-device(config-if-vlan)# ip address dhcp fallback 192.168.10.2 255.255.0.0
my-device(config-if-vlan)# exit
4. Leave global configuration mode and go back to Privileged Exec: my-device(config)# end
5. Inspect and verify the configuration (some output omitted for brevity):
my-device# show running-config
Building configuration...
hostname my-device
username admin privilege 15 password encrypted
