From today on we review together to learn the debugging of routers and switches. Based on the CCNA tutorial, we practice a few small commands every day, and make up a little, and finally become an amplifier.Enable: Enter privileged mode and the command prompt becomes hostname# after runConfigure Terminal: Enter the global mode command prompt to change to hostname (config) #Hostname: Naming the deviceExit quit PrivilegeNo IP domain-lookup: Turn off add
