Basic Interface configurations includes:

IN THE BELOW EXAMPLE WE WILL CONFIGURE A SUB-INTERFACE

Interface Gi 1.1
Vlan 10
Ip address 100.100.100.100 /24
Security level 100

#configure terminal (Specifying the config mode)
#int gi 1.1 (Dividing the interface for vlan 10 only)
#vlan 10 (Assigning vlan 10 to above interface)
#ip address 100.100.100.100 255.255.255.0 (ip address)
#security-level 100 (Assigning the security level)
#nameif Inside (Naming the Interface)
#no shut (Waking up the interface)
