IOS Modes on Cisco Devices

As stated earlier in this guide, the Cisco IOS is comprised of several modes,

each of which contains a set of commands specific to the function of that

mode.

By default, the first mode you enter when logging into a Cisco device is

User EXEC mode. User mode appends a “>” after the device hostname:

Router>

No configuration can be changed or viewed from User mode. Only basic

status information can be viewed from this mode.

Privileged EXEC mode allows all configuration files, settings, and status

information to be viewed. Privileged mode appends a “#” after the device

hostname:

Router#

To enter Privileged mode, type enable from User mode:

Router> enable

Router#

To return back to User mode from Privileged mode, type disable:

Router# disable

Router>

Very little configuration can be changed directly from Privileged mode.

Instead, to actually configure the Cisco device, one must enter Global

Configuration mode:

Router(config)#

To enter Global Configuration mode, type configure terminal from

Privileged Mode:

Router# configure terminal

Router(config)#

To return back to Privileged mode, type exit:

Router(config)# exit

Router#
