vPC 개체 추적
소개
이 문서에서는 vPC 개체 추적, 사용 이유 및 작동 방법에 대해 설명합니다.
vPC 개체 추적
네트워크 다이어그램
이 데모에 사용되는 네트워크 다이어그램은 다음과 같습니다.
vPC 피어 링크는 Port-channel 1입니다. Ethernet 5/1은 vPC peer-keepalive 링크입니다. 각 N7K 박스마다 L3/30 링크 e3/3 및 e3/4를 통해 연결되는 두 개의 코어 라우터가 있습니다. N5KA 및 N5KB는 vPC 100 및 vPC 101에 연결된 L2 스위치 vPC를 시뮬레이션하고 있습니다. N7KA는 vPC 기본 디바이스입니다.

vPC 개체 추적은 이와 같은 시나리오에서 사용됩니다. 하나의 M132 모듈이 vPC 피어 링크와 코어에 대한 L3 업링크에 사용됩니다. HW 장애로 인해 M132 모듈을 잃을 경우 vPC 피어 링크와 L3 업링크가 손실됩니다. vPC 보조 박스(N7KB)에서 이러한 문제가 발생할 경우 운영 기본 피어가 운영 보조 서버에서 vPC 포트 채널 및 VLAN 인터페이스를 일시 중단하므로 문제가 되지 않습니다. 문제는 운영 기본 장치(N7KA)에서 HW 오류가 발생한 경우에 발생합니다. 개체 추적을 사용하지 않으면 N7KB에서 모든 vPC 포트 채널 및 VLAN 인터페이스를 일시 중단합니다. 피어 링크도 다운됩니다. 이 시나리오에서는 코어 트래픽을 vPC VLAN으로 라우팅할 방법이 없습니다.
Object Tracking(개체 추적)은 운영 기본 시스템의 vPC를 다운시켜 코어에 남은 업링크가 있는 상자의 Vlan 인터페이스 및 vPC 포트 채널을 종료하지 않도록 하는 이 시나리오를 통해 이를 해결합니다.
다음은 ethanalyzer를 사용하는 vPC 피어 keepalive 메시지입니다.

이제 당신은 이 상태로 남아 있습니다. N7KA는 vPC 기본 피어이지만 N7KB가 일시 중단되지 않도록 vPC 피어 keepalive 메시지 전송을 중단합니다. N7KB는 업링크가 있는 유일한 시스템입니다.

vPC Peer-keepalive 실패 세부 정보:
peer-keepalive 링크를 사용하여 어떤 일이 발생하는지 확인하려면 테스트를 다시 실행합니다.
keepales를 양방향으로 전송합니다. 현재 모든 것이 작동되고 있습니다.
