♦ VTP
- VLAN Trunking Protocol
- 여러개의 스위치들이 VLAN 설정 정보를 교환할 때 사용하는 프로토콜
♦ VTP 동작 원리
- 스위치에서 VLAN을 추가, 수정 삭제할 때 새로운 VLAN정보 전송 필요
- 스위치는 VTP 설정번호를 기존값보다 1증가 시켜 전송
- 수신한 번호가 크면 수신한 VLAN정보로 교체
- 수신한 번호가 같으면 정보 무시
- 수신한 번호가 낮으면 자신의 VTP정보를 전송
♦ VTP 도메인
- VTP 도메인 이름이 같은 스위치간에만 정보를 교환
- VTP가 동작하려면 도메인이름이 같아야 되고 trunk연결 되어있어야 함
- 하나의 스위치에서 VTP도메인 이름을 지정하면 자동으로 연결된 스위치도 VTP 도메인 이름 설정
- 스위치 간 VTP 도메인 이름이 다르면 VTP정보 무시
- VTP정보는 라우터를 넘어가지 못함
- 설정 : vtp domain "xxx"
- 확인 : show vtp status
♦ VTP모드
1. server mode(기본 모드) : VLAN생성, 삭제, 변경 가능. VTP정보를 다른 스위치에게 전송. 최신정보로 업데이트. 중계
2. client mode : VLAN 생성, 삭제 불가능. VTP정보 전송. 최신정보로 업데이트. 중계
3. transparent mode(VTP 미사용) : VLAN 생성, 삭제 가능. VTP정보 전송하지 않음. 최신정보로 업데이트하지 않고 중계만 함.
※ VTP모드 설정 : vtp mode "xxx"
♦VTP pruning
- broadcast를 보낼 필요가 없을 때 trunk포트를 통해 차단
- 설정 : vtp pruning
♦ 확장 VLAN
- VLAN 번호가 1006 ~ 4094
- VTP transparent 모드에서 설정가능
- VTP는 확장 VLAN을 지원하지 않음(server, client)
♦ 새로운 스위치 추가할 때
- VTP에 의해서 스위치가 잘못 동작하지 않도록 VTP 설정 번호를 초기화 시켜 0으로 만들어야 함
- 새로운 스위치 연결시 설정 번호가 기존 스위치보다 높으면 기존 스위치들의 VLAN설정 정보가 모두 삭제됨(server, client)
- 초기화 방법
1. delete clan.dat → reload
2. trasparent 모드로 변경후 server, client모드로 변경
♦ VTP
- VLAN Trunking Protocol
- The protocol used by several switches to exchange VLAN configuration information.
♦ How VTP works
- New VLAN information needs to be added when adding, modifying and deleting VLANs on the switch
- The switch transmits the VTP setup number by 1 more than the existing value.
- If received number is big, it replaces with received VLAN information
- Ignore information if the same number is received
- If the received number is low, it transmits its own VTP information.
♦ VTP domain
- exchange information only between switches with the same VTP domain name
- For VTP to work, domain name must be same and trunk must be connected.
- If you specify a VTP domain name on one switch, the automatically connected switch also sets the VTP domain name
- Ignore VTP information if the switch-to-switch VTP domain name is different
- VTP information could not cross the router
- Setting: vtp domain "xxx"
- Verification: show vtp status
♦ VTP mode
1. server mode (default mode): Create, delete, and change VLANs. Send VTP information to another switch. Update to the latest information. Relay
2. client mode: VLAN creation, deletion disabled. VTP information transfer. Update to the latest information. Relay
3. transparent mode (VTP not used): VLAN can be created and deleted. Do not transmit VTP information. Relay only without updating to the latest information.
※ VTP mode setting: vtp mode "xxx"
♦ Pruning VTP
- Block through trunk port when broadcast is not needed
- Setting: vtp pruning
♦ Extended VLAN
- VLAN numbers 1006 to 4094
- Configurable in VTP transparent mode
- VTP does not support extended VLANs (server, client)
♦ When adding a new switch
- The VTP setup number should be initialized to 0 to prevent the switch from malfunctioning by VTP.
- When the new switch connection number is higher than the existing switch, all the VLAN configuration information of the existing switches is deleted (server, client)
- Initialization method
1. delete clan.dat → reload
2. Change to trasparent mode, then change to server, client mode
