Basic configuration on devices:

• set hostname;
• set secret password;
• set banner motd;
• encrypt passwords;
• line console 0
  • set synchronous logging
  • set idle time
  • set password
  • use login
• line vty 0 15
  • set password
  • use login
  • set history size

Below you have the commands. The hostname is at the end, because if you want to copy-paste them, you will have to modify the hostname:

enable
conf t
enable secret cisco
banner motd #AUTHORIZED ACCESS ONLY !#
service password-encryption
line console 0
logging synchronous
exec-time 0 0
password cisco
login
history size 256
line vty 0 15

history size 256
exit
