Cisco Router Basic Configuration

There are three mode in a router
1. Exe mode
2. Privilege mode
3. Configuration mode
Exe Mode: Exe mode can be determined by seeing that the router in the following symbol:
“router > ” [indicating that router in exe mode],

Privilege Mode: By typing enable [router > enable / en] in the exe mode we can enter in to the privilege mode.
router > enable / en
router #                       [indicating privilege mode]

Privilege mode commands are given below:
# show / sh version
# show history
# show terminal
# show start
# show run
# show flash
# show int
# show ip int br
# show controller
# show ip route [to see the routing table]
# show int S0/0

Configuration Mode: To move from privilege mode to configuration mode we have to give the configuration terminal or config t command in the privilege mode.

Ex.  Router # configuration terminal / config t
Router (config)#   [indicating the configuration mode]
