Switch IP Address
Default IP
enable configure terminal ! interface vlan 1 ip address 192.168.1.111 255.255.255.0 no shutdown exit
Default Gateway

VLAN IP
enable configure terminal ! interface vlan 10 ip address 192.168.11.100 255.255.255.0 no shutdown ! interface vlan 20 ip address 192.168.15.100 255.255.255.0 no shutdown exit
Ports
enable configure terminal ! interface fa0/1 switchport mode access siwthcport access vlan 10 exit interface fa0/2 switchport mode access siwthcport access vlan 20 exit interface fa0/3 switchport mode access siwthcport access vlan 30 exit ! interface range fa0/10-20 switchport mode access siwthcport access vlan 20 exit ! interface range fa0/21-24 switchport mode access siwthcport access vlan 30 exit
Multiple VLAN on Single Interface
enable configure terminal ! vlan 10 name Corporate exit vlan 20 name Wireless exit vlan 30 name Test exit ! interface gigabitEthernet 0/0 no shutdown ! interface gi0/0.10 encapsulation dot1Q 10 ip address 192.168.1.254 255.255.255.0 ! interface gi0/0.20 encapsulation dot1Q 20 ip address 192.168.2.254 255.255.255.0 ! interface gi0/0.30 encapsulation dot1Q 30 ip address 192.168.3.254 255.255.255.0 ! exit
