이 단계에서는 VSS 대기 섀시가 재부팅되고 새 이미지로 다시 로드되며 새 이미지를 실행하는 SSO(Stateful Switchover) 이중화 모드에서 VSS 대기 섀시로 초기화됩니다. 이 단계는 Bulk sync succeeded(대량 동기화 성공) 메시지에 표시된 대로 섀시 컨피그레이션이 동기화될 때 완료됩니다. 새 이미지가 로드되고 VSS 대기 섀시가 SSO 모드로 전환되는 데 몇 초에서 몇 분 정도 걸릴 수 있습니다.

7단계. 롤백 타이머를 중지하려면 issu acceptversion 명령을 사용합니다. 타이머가 만료되면 업그레이드된 섀시가 다시 로드되고 이전 소프트웨어 버전으로 되돌아가기 때문에 이 과정이 필요합니다.

사례 연구 트러블슈팅

시나리오 1. 교차 VSL 연결이 없을 때 지연 모드에서 업그레이드

WS-C6504-E-1#issu loadversion 1/1 bootdisk:s2t54-adventerprisek9-mz.SPA.155-1.SY13.bin 2/1 slavebootdisk:s2t54-adventerprisek9-mz.SPA.155-1.SY13.bin
WS-C6504-E-1#*Apr 16 23:31:12.528: SW1:  Quad-sup ISSU Staggered mode VSL requirement(Parallel/Cross VSL connectivity) is NOT met. Disable Staggered mode using config cli "no issu upgrade staggered" to perform ISSU in default mode which is In-tandem.

진행할 교차 VSL 연결이 없으므로 요구 사항이 충족되지 않았다는 오류 메시지가 표시됩니다.

스태거링된 를 비활성화하여 업그레이드를 수행할 수 있습니다.

Tandem 대 Stagger

VSS를 탠덤 또는 듀얼 슈퍼바이저(SUP)용으로 업그레이드할 수도 있지만, 수퍼바이저의 전체 부팅 기간 동안 섀시 하나가 오프라인 상태가 됩니다.

한 번에 하나의 수퍼바이저가 Sup2T 지연 모드의 기본 모드에서 다시 로드됩니다. 즉, 라인카드가 다시 로드될 준비가 되면 해당 버전을 사용하는 수퍼바이저가 존재하게 됩니다. 라인 카드가 수퍼바이저보다 훨씬 빠르게 다시 로드되므로 결과적으로 섀시의 다운타임이 크게 줄어듭니다.

또한 오래된 프로그램을 사용하는 수퍼바이저를 사용할 수 있으므로 필요한 경우 롤백 시간을 훨씬 단축할 수 있습니다. Sup2T의 경우 기본 모드는 스태거링됩니다.

스태거링된 업그레이드 방법은 이 명령을 사용하여 비활성화할 수 있습니다.

시나리오 2. 이전 이미지가 있는 활성 적중

기본적으로 ISSU Run Version에서 공격을 받을 수 있습니다.

ISSU Run Version(ISSU 실행 버전)에 롤백 타이머가 이미 활성화되어 있습니다. 더 이상 진행할 수 없는 경우 타이머가 자동으로 이전 이미지로 롤백합니다.

ISSU 커밋 버전과 관련하여, 수락된 버전을 제공했으므로 롤백 타이머가 비활성화됩니다. 따라서 이전 이미지로 롤백하려면 이 명령을 수행해야 합니다.

WS-C6504-E-1# issu abortversion

시나리오 3. Post Switchover Standby가 작동 중이 아님

VSL(Virtual Switch Link) 링크를 물리적으로 끊고 USB/TFTP 방법을 사용하여 디바이스를 새 이미지로 업그레이드합니다.

업그레이드 후 디바이스의 전원을 끕니다. VSL 링크를 연결하고 디바이스를 VSS로 가져와서 대기 상태를 형성할 수 있도록 합니다.

시나리오 4. 업그레이드 후 ICS SUP가 이전 버전으로 유지됨

액티브 가 정상적으로 작동하므로 영향을 받지 않는 예비 섀시 또는 스탠바이 섀시에 SUP만 연결합니다.

USB/TFTP 방법을 사용하여 디바이스를 새 이미지로 업그레이드합니다.

그런 다음 전원을 끄고 동일한 슬롯으로 가져와서 이미지가 업그레이드되고 최신 이미지로 다시 In-Chassis Standby(ICS)로 돌아옵니다.
