The following table shows the commands and their order of use to configure a Cisco router. The commands allow the network device to be defined from the administrator's name and password to the configuration of communication protocols and various security mechanisms. Essentially, all commands and their order of use refer to the entire series of devices of this type.

Commands for configuring of Cisco router
==================================================================================
UEM = User Exec Mode (view only)
PEM = Privileged Exec Mode (enabled)
GCM = Global Configuration Mode (configuration)
-------------- UEM -> PEM -> GCM -> SCM -----------------
SCM = Specific Configuration Mode
---------------------------------------
ICM = Interface CM (part of SCM)
LCM = Line CM (part of SCM)
RCM = Router CM (part of SCM)
---------------------------------------------------------
SCM #exit --> GCM
SCM #<CTRL>+<Z> --> PEM
