Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
ps:
Configure terminal means configuring the terminal. The word is long. The following solutions can be used:
- Tab key auto-completion
- Abbreviated as conf t

Switch(config)#?
Configure commands:
access-list Add an access list entry
banner Define a login banner
boot Boot Commands
cdp Global CDP configuration subcommands
clock Configure time-of-day clock

Convert global configuration mode to interface configuration mode:
Switch(config-if)#interface f0/1
Switch(config-if)#
Convert global configuration mode to vlan configuration mode:
Switch(config)#vlan 4
Switch(config-vlan)#
5. Mode switching diagram
2. Switch name, password and other settings
1. In global mode-rename the switch
In global mode:
Switch(config)#hostname song
song(config)#
2. In interface mode - configure port speed and working mode
2.1 Configure port speed
song(config-if)#speed ?
10 Force 10 Mbps operation
100 Force 100 Mbps operation
auto Enable AUTO speed configuration
ps: By default, it will automatically match 10Mbps or 100Mbps
song(config-if)#speed 10
song(config-if)#speed 100
song(config-if)#speed auto
song(config-if)#
2.2 Configure working mode
song(config-if)#duplex ?
auto Enable AUTO duplex configuration
full Force full duplex operation
half Force half-duplex operation
3. In privileged mode - View switch history commands
In principle, you can scroll up to find all the historical commands one by one, but it is inconvenient.

4.Revocation of order
Some commands can be overwritten to achieve the purpose of undoing and writing again, but some commands can only be completed by undoing and writing again.
song(config-if)#speed 100
song(config-if)#no speed 100
song(config-if)#
