Basic configurationno ip domain-lookup | hostname [hostname] | service password-encryption | banner motd #Unauthorized access to this device is prohibited!# | enable secret class | line console 0 | line vty 0 15 | password cisco |
This is just basic configuration and has nothing to do with vtp or etherchannel
VTP commandsvtp domain [domain] | Set (change) the vtp domain | vtp mode [server|client|transparent] | Set vtp mode | vtp password [password] | Set vtp password | show vtp status | Verification command concerning vtp |
Show vtp status also shows the revision number of a certain switch.

An etherchannel summarizes a few physical cables to one logical cable and speeds up the entire process of data transmission -> 4 cables -> 3.9 times faster
DTP commandsinterface f0/1 | Enters interface configuration mode for f0/1 | switchport mode [mode] | Sets mode | show interfaces trunk | Verification command concerning dtp |
| | Link Aggregationinterface range f0/[number-number] | Enters the interface configuration mode for a couple interfaces | switchport mode trunk | Sets the switchport | switchport trunk native vlan | Specifies the port's native VLAN | channel-group [number] mode [mode] | Adds the current "selected" ports to etherchannel 1 |
Is the same as etherchannel, but all devices can use it, so it's not cisco only.
VLAN commandsvlan [number] | Creates vlan with a certain number and automatically enters vlan configuration mode | name [name] | Give the vlan a specific name | show vlan brief | Verify your configuration |
By default all interfaces are in vlan 1
