Basic configuration on devices
Basic configuration on devices:
- set hostname;
- set secret password;
- set banner motd;

- line console 0
- set synchronous logging
- set idle time
- set password

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

When to use straight through cable and when to use crossover cable
On the left hand side are devices that use straight-through cable and on the right hand side are devices that use crossover cables.
These are the devices that use a straight-through cable:
- Switch – Router
- Switch – PC
- Switch – Server
- Hub – PC
- Hub – Server

- Switch – Switch
- Switch – Hub
- Hub – Hub
- Router – Router
- Router – PC
- Router – Server
- PC – PC
But nowadays the standard is becoming obsolete due to the fact that Auto-MDIX (automatic medium dependent interface crossover) technology on devices grows with each device that supports it. This means that ports do not need to know what type of cable is used when you connect two devices.
