5. Cisco 2 - Routers Perrine. J Page 53/7/2016 Chapter 3 Configure a Router - Show One will compile a list of “show” commands to help debug the router. Some of the commands will be: show interface show interface serial port show version show protocol show startup-configuration show running-configuration

6. Cisco 2 - Routers Perrine. J Page 63/7/2016 Chapter 3 Configure a Router - Interfaces In the following commands, type, refers to either, ethernet, or serial ports. Router(config)#interface type port OR Router(config)#interface type slot/port To bring a port down, or ‘shut it down’, do: Router(config)#interface type port Router(config-if)#shutdown To bring ‘up’ an interface or ‘initialize’ it, do: Router(config)#interface type port Router(config-if)#no shutdown

7. Cisco 2 - Routers Perrine. J Page 73/7/2016 Chapter 3 Configure a Router - Interfaces Before one does a ‘no shutdown’, all interfaces are in the state: administrative down, line protocol down

8. Cisco 2 - Routers Perrine. J Page 83/7/2016 Chapter 3 Configure a Router - Interfaces When you are at interface mode, you need to give characteristics to the ethernet or serial port: Router(config)#interface serial 0/0 Router(config-if)#ip address If the serial port is the DCE, then the clock rate must be applied: Router(config-if)#no shutdown Router(config-if)#clock rate 56000 Router(config)#interface serial 0/0 Router(config-if)#ip address

9. Cisco 2 - Routers Perrine. J Page 93/7/2016 Chapter 3 Configure a Router To erase the configuration of a router: Router#erase startup-config Router#reload To load the running configuration of a router into NVRAM, do: Router#copy running-config startup-config
