연속적일때.
SW1(config)#int range fa0/23 - fa0/24
연속적이지 않을때
SW1(config)#int range fa0/23 , fa0/25
2950 스위치 이상일때.

Inter - Vlan (Router 에서 설정)
하나의 inter face 를 가지고 여러개의 Vlan과 통신 시켜 준다.
단점 : 혼잡발생
Router 설정
int f0/0 //
no shutdown
int fa0//0.10 // Sub interface
encapsulation dot1q 10 // 10은 vlan 번호
int fa0/0.20
encapsulation dot1q 20 // 20은 vlan 번호
ip address 172.16.2.1 255.255.255.0
Switch interface fa0/1 는 trunk 로 설정 해 주어야 한다.
