Cisco Router Modes-(Cisco exe Mode, Cisco Enable Mode, Global Configuration Mode) and Cisco Commands list

Cisco router and Cisco switch have different modes for different operations depending upon the privileges of the users. Cisco router and switch basically have three modes namely user exe mode, enable mode(privileged exe mode) and global configuration mode. Each mode offers different Cisco commands for router configuration or Cisco switch configuration.

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  is the command used for entering 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.
