What Does Line console 0 means:
Line console is referred to the physical port of a switch/router which is used for connecting to a system i.e PC or laptop for configuration or monitoring the switch/router. Where as the “0” in line console 0 command means that we have one console port on our router/switch therefore we are connecting through that single port. If there are more than one console ports on a specific router/switch then we can specify those ports as console line 0 being the first port , console line 1 as the second port and console line 2 as a third port.
