I am reading book 'CCNA Routing and Switiching Study Guide - Lammle, Todd' wherein there was a command to create an interface (int f0/0).
On CISCO Router command when I am giving a command Corp(Config)#int f0/0
It is displaying error message as "Invalid interface type and number". Please help me with this command.
Just to rule out, there are routers that only have GigaEthernet interfaces.
Thy this commands:
Router(config)#do show running-config
Router(config)#do show interfaces
In order to help us complete the basic configuration of our Cisco routers, this lesson introduces the use of configuration modes, and how they interact to help us configure the router from the command-line interface.
