사전 요구 사항
요구 사항
이 문서에 대한 특정 요건이 없습니다.
사용되는 구성 요소
이 문서의 정보는 다음 소프트웨어 및 하드웨어 버전을 기반으로 합니다.
- CIsco2000용 ESM
- CGR 2010
이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다. 이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다. 현재 네트워크가 작동 중인 경우, 모든 명령어의 잠재적인 영향을 미리 숙지하시기 바랍니다.
문제
공장 재설정을 수행하려면 ESM 모듈의 비밀번호 복구를 수행하거나 CGR 2010에서 손상된 소프트웨어 이미지로 ESM 모듈을 복구하십시오.
참고: 이 절차를 수행하려면 콘솔을 통해 CGR 2010에 직접 연결해야 합니다.
솔루션
1단계. 콘솔을 통해 CGR 2010에 직접 연결합니다.
2단계. service-module gix/x/x reload 명령을 실행하여 ESM을 다시 로드합니다.
service-module gi0/0/0 reload
3단계. ESM 모듈이 부팅될 때 핀을 사용하여 ESM 모듈의 ES(Express Setup) 버튼을 눌러 부팅 시퀀스를 중단합니다.
4단계. service-module gix/x/x session을 실행하여 ESM을 입력합니다.
5단계. 스위치에서 한 번: 프롬프트, 플래시 초기화: flash_init를 실행합니다. 5단계 후 해당 섹션을 따릅니다.
공장 재설정
6단계. config.text 및 vlan.dat 파일을 삭제합니다.
switch: delete flash:config.text switch: delete flash:vlan.dat
7단계. 시스템 이미지를 로드하고 boot flash:<image-name> 명령을 실행합니다.
손상된 소프트웨어 이미지로 ESM 복구
8단계. x-modem을 사용하여 새 이미지를 ESM에 복사할 수 있습니다. ESM 스위치에서: 프롬프트에서 enter 키를 여러 번 눌러 줄을 지웁니다.
9단계. Ctrl + Shift + 6 + X를 눌러 CGR 2010으로 돌아갑니다. 성공적으로 전송할 xmodem에 대한 ESM 세션을 지웁니다.
service-module gigabitEthernet 0/0/0 session clear
10단계. CGR에서 copy 명령 copy flash:<file from CGR2010> xmodem을 사용합니다. 새 ESM 이미지를 xmodem에 복사합니다.
cgr2010-ast03-lab#copy flash:test1 xmodem:test2 **** WARNING **** x/ymodem is a slow transfer protocol limited to the current speed settings of the auxiliary/console ports. The use of the auxiliary port for this download is strongly recommended. During the course of the download no exec input/output will be available. ---- ******* ---- Proceed? [confirm] Destination filename [test2]? Service Module slot number? [1]: 0 Service Module interface number? [0]: 1k buffer? [confirm] Max Retry Count [10]: 2 Xmodem send on slot 0 interface 0. Please be sure there is enough space on receiving side. Continue? [confirm] Ready to send file...........C!!! 3072 bytes copied in 24.596 secs (125 bytes/sec)
11단계. ESM 이미지를 xmodem에 복사한 후 다음을 수행합니다. 성공적으로 ESM 모듈에 로그인합니다.
service-module gigabitEthernet 0/0/0 session
12단계. 스위치에서: esm에서 프롬프트를 표시하고 boot 명령을 사용하여 적절한 이미지를 로드합니다.
