In this video I cover the very basic router and switch IOS configuration commands that you will use in week 2 of my Cisco CCNA Introduction to Networks course: You can download the text file from this video here: https://drive.google.com/open?id=13PgL3He2XAJZRdV2s4VeuRdxQ3dxouza ================================= Basic Router Commands ================================= Router(greater than sign) ---User EXEC mode exit Router(greater than sign) ? Router(greater than sign) enable --------------- Router# ---Privileged EXEC mode disable, exit Router# ? ----------------- Router# configure terminal Router(config)# ---Global Config mode exit, end, Ctrl+c, Ctrl+z Router(config)# ? ----------------- Router(config)# line vty 0 15 Router(config)# line console 0 Router(config-line)# ---Line configuration mode exit, end, Ctrl+c, Ctrl+z Router(config-line)# ? ---------------------------- Router(config)# interface gigabitEthernet 0/0/0 Router(config-if)# ---Interface configuration mode exit, end, Ctrl+c, Ctrl+z Router(config-if)# ? ---------------------------- Router# Router# configure terminal Router# show ?

Router(conf)# enable password class Router(conf)# enable secret class Router(conf)# service password-encryption Router(config)# line vty 0 15 Router(config)# line console 0 Router(config)# interface gigabitEthernet 0/0/0 ---------------------------------------------------- Router(config-line)# Router(config-line)# password cisco Router(config-line)# login Router(config-line)# transport input all (line vty) ---------------------------------------------------- Router(config-if)# Router(config-if)# interface gigabitEthernet 0/0/0 Router(config-if)# int g0/0 //command abbreviation Router(config-if)# ip address 192.168.1.1 255.255.255.0 Router(config-if)# no shutdown ================================= Basic Switch Commands ================================= Switch(greater than sign) ---User EXEC mode exit Switch(greater than sign) enable --------------- Switch# ---Privileged EXEC mode disable, exit ----------------- Switch# configure terminal Switch(config)# ---Global Config mode exit, end, Ctrl+c, Ctrl+z ----------------- Switch(config)# line vty 0 15 Switch(config)# line console 0 Switch(config-line)# ---Line configuration mode exit, end, Ctrl+c, Ctrl+z ---------------------------- Switch(config)# interface vlan 1 Switch(config-if)# ---Interface configuration mode exit, end, Ctrl+c, Ctrl+z ---------------------------- Switch# Switch# configure terminal Switch# show ? Switch# show running-config Switch# copy running-config startup-config Switch# ping 192.168.1.100 Switch# traceroute 192.168.1.100 Switch# ssh 192.168.1.100 Switch# telnet 192.168.1.100 Switch# debug ?

Router(conf-line)# logging synchronous //prevents logging output from interrupting your command input
