- 본 글은 MC-AE Mode인 "active-active"와 "active-standby"의 차이를 확인하는 목적
1. Introduction to MC-LAG MC-AE Mode
- MC-LAG에서 MC-AE Mode는 "active-active" 또는 "active-standby"로 설정 가능
1) MC-AE Mode Active-Active
- 두 MC-LAG Peer의 MC-AE 인터페이스를 동시에 사용할 수 있어 일반적으로 해당 Mode를 사용
- ICL이 반드시 필요
2) MC-AE Mode Active-Standby
- 두 MC-LAG Peer 중, Active Status 장비의 MC-AE 인터페이스만 사용 가능
- Standby Status 장비의 LACP는 Standby로 유지되어 MC-LAG Client도 해당 LACP Member Link 사용 불가
- MC-LAG Peer의 "Mux State"는 "Waiting"으로 표시
- MC-LAG Client의 "Mux State"는 "Attached"로 표시
- 두 MC-LAG Peer의 MC-AE 인터페이스 동시 사용 불가능
- 둘 중, 하나의 MC-LAG Peer의 MC-AE 인터페이스를 사용할 수 없으므로 ICL이 불필요
- "mc-ae mode active-standby" 명령을 먼저 commit 한 장비가 "active status"로 동작
- 해당 모드는 "Hidden Configuration"으로, "tab" 버튼으로 자동 완성 불가능
3) 테스트 장비
| Hostname | Model | OS Version | BIOS(Firmware) |
| QFX1 | QFX5120-48T-6C | 23.4R2-S2.1 | CBDE_P_LIG1_00.29.01 |
| QFX2 | QFX5120-48T-6C | 23.4R2-S2.1 | CBDE_P_LIG1_00.29.01 |
| EX3 | EX4300-24T | 21.4R3-S3.4 | - |
- 아래 테스트한 내용은 위와 같은 장비로 진행
