(2) 서로 다른 Switch 간 동일 VLAN 통신 확인

  • SW1의 Access Mode인 포트로 Import할 때, 포트에 설정한 10번 Tag를 Frame에 추가
  • SW1의 Trunk Mode인 포트로 Export할 때, 포트에 설정한 10번 Tag가 Frame에 존재하므로 Tag 유지
  • SW2의 Trunk Mode인 포트로 Import할 때, 포트에 설정한 10번 Tag가 Frame에 존재하므로 Tag 유지
  • SW2의 Access Mode인 포트로 Export할 때, 포트에 설정한 10번 Tag를 Frame에서 제거

 

  • SW2의 Access Mode인 포트로 Import할 때, 포트에 설정한 10번 Tag를 Frame에 추가
  • SW2의 Trunk Mode인 포트로 Export할 때, 포트에 설정한 10번 Tag가 Frame에 존재하므로 Tag 유지
  • SW1의 Trunk Mode인 포트로 Import할 때, 포트에 설정한 10번 Tag가 Frame에 존재하므로 Tag 유지
  • SW1의 Access Mode인 포트로 Export할 때, 포트에 설정한 10번 Tag를 Frame에서 제거

 

2) 서로 다른 Switch 간 다른 VLAN 통신

(1) 서로 다른 Switch 간 다른 VLAN 통신 Configuration

(2) 서로 다른 Switch 간 다른 VLAN 통신

  • SW1의 Access Mode인 포트로 Import할 때, 포트에 설정한 10번 Tag를 Frame에 추가
  • SW1의 Trunk Mode인 포트로 Export할 때, 포트에 설정한 10번 Tag가 Frame에 존재하므로 Tag 유지
  • SW2의 Trunk Mode인 포트로 Import할 때, 포트에 설정한 10번 Tag가 Frame에 존재하므로 Tag 유지
  • SW2의 Access Mode인 포트로 Export할 때, 포트에 설정한 20번 Tag가 Frame에 없으므로 Frame의 Tag를 제거하지 못하여 ge-0/0/1로 Export 불가
