@Switch Port 설정
- Access Port
하나의 VLAN 설정 해당 VLAN Traffic만 처리
Switch(config)#interface fastethernet <port>
Switch(config-if)#switchprt mode access
Switch(config-if)#switchport access vlan <VLAN-ID>

- Trunk Port
어떤 VLAN 에도 속하지 않고 모든 VLAN Traffic 전달
Switch(config)#interface fastethernet <port>
Switch(config-if)#switchport mode trunk
Switch(config-if)#switchport trunk allowed vlan all

@@VTP
각 Switch마다 VLAN 정보를 동기화 시켜주는 프로토콜

Server : VLAN 생성, 수정, 삭제 할 수 있는 모드이고 Client에게 VLAN정보를 복제한다.
Client : VLAN 생성, 수정, 삭제 할 수 없는 모드이고 Server를 통해서 VLAN 정보를 받아서 사용한다.
Transparent : VLAN 생성, 수정, 삭제 할 수 있는 모드이지만 VLAN 정보를 동기화 할 수 없는 독립적인 모드이다.

@VTP 설정
-VTP Domain 생성으로 같은 Domain인 끼리만 동기화
Switch(config)#vtp domain <Domain>

-VTP Password를 통해 인증된 Domain인 끼리만 동기화
Switch(config)#vtp password <Password>

-VTP Mode 설정
Switch(config)#vtp mode <server/client/transparent>
