Cisco router commands are common across all Cisco devices, so learning these commands enables one to work on and configure all Cisco routers. Cisco is a top network device dealer that makes routers designed for large companies and smaller models for personal networks. Commands change depending on which mode a user is working with, and the three modes of the router are configuration, disabled, and
. enabled. Some of the most common Cisco router commands used are ping, help, exit, enable, show, disable, logout, and disconnect. A question mark may also be typed as a command in order to see other commands available in a specific mode. You can find more information here: http://www.tomax7.com/mcse/cisco_commands.htm
