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.
Following is the list of commands you can enter in Privileged exe / enable mode:
auto Exec level Automation
clear Reset functions
clock Manage the system clock
configure Enter configuration mode
connect Open a terminal connection
copy Copy from one file to another
debug Debugging functions (see also ‘undebug’)
delete Delete a file
dir List files on a filesystem
disable Turn off privileged commands
disconnect Disconnect an existing network connection
enable Turn on privileged commands
erase Erase a filesystem
exit Exit from the EXEC
logout Exit from the EXEC
mkdir Create new directory
more Display the contents of a file
no Disable debugging informations
ping Send echo messages
reload Halt and perform a cold restart
resume Resume an active network connection
rmdir Remove existing directory
send Send a message to other tty lines
setup Run the SETUP command facility
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
undebug Disable debugging functions (see also ‘debug’)
vlan Configure VLAN parameters
write Write running configuration to memory, network, or terminal
Router1(config)# Global Configuration mode :
