I tried to set (change) the mode of my port, and I read the book and followed it step by step. But I still get a lot of error.
There were what I input.
(Routing) (Interface 0/3)#switchport mode general
(Routing) (Interface 0/6)#switchport mode access
(Routing) (Interface 0/6)#switchport mode trunk
All of the problems are Invalid input detected at '^' marker.
I search a lot, and everyone always says "switchport mode access/trunk/general", but I could not input it.
