Cisco Router Modes (User exe Mode, Enable Mode, Globel Configuration Mode)

Router Modes

Router1>   User exe Mode :

This is the default mode of cisco routers and is called user exe mode. In this mode user cannot write or add configuration to the router. User exe mode is good for those users who are not supposed to save any changes to the router but can view the configuration.

This mode allow users to run quite a few show commands which are as follows:

connect        Open a terminal connection

disable         Turn off privileged commands

disconnect   Disconnect an existing network connection

enable          Turn on privileged commands

exit               Exit from the EXEC

logout          Exit from the EXEC

ping             Send echo messages

resume        Resume an active network connection

show            Show running system information

ssh               Open a secure shell client connection

telnet           Open a telnet connection

terminal      Set terminal line parameters

traceroute   Trace route to destination

Router1#  Privileged exec mode / enable mode :

Router1> enable    Entering this command will get you to the enable mode.

This # sign after your host name confirms that you are in privileged/enable mode, in our case the host name is Router1 and Router1# confirms that we are in privileged mode. This mode has more commands for showing and adding configuration to the router.
