소개

이 문서에서는 Cisco Connected Grid Router 2010(CGR 2010)에서 ESM(Ethernet Switch Module)의 공장 재설정 또는 비밀번호 복구를 수행하는 방법에 대해 설명합니다. 이 절차는 손상된 소프트웨어 이미지가 있는 ESM 모듈을 복구하는 데에도 사용할 수 있습니다.

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 CGR 2010에서 ESM 모듈의 비밀번호 복구 또는 손상된 소프트웨어 이미지를 사용하여 ESM 모듈을 복구합니다.

참고:이 절차를 수행하려면 콘솔을 통해 CGR 2010에 직접 연결해야 합니다.

솔루션

1단계. 콘솔을 통해 CGR 2010에 직접 연결합니다.

2단계. ESM을 다시 로드하려면 service-module gix/x/x reload 명령을 실행합니다.

service-module gi0/0/0 reload

3단계. ESM 모듈이 부팅될 때 ESM 모듈의 ES(Express Setup) 버튼을 눌러 부팅 시퀀스를 중단합니다.

4단계. ESM을 입력하여 service-module gix/x/x 세션을 실행합니다.

5단계. 스위치에서 한 번:프롬프트, 플래시 초기화:flash_init를 실행합니다. 5단계 이후 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. 새 이미지를 x-modem을 사용하여 ESM에 복사할 수 있습니다.ESM 스위치에서프롬프트를 여러 번 눌러 선을 지웁니다.

9단계. CGR 2010으로 돌아가려면 Ctrl + Shift + 6 + X를 누릅니다.성공적으로 전송하려면 xmodem에 대한 ESM 세션을 지웁니다.

service-module gigabitEthernet 0/0/0 session clear

10단계. CGR에서 copy 명령 copy flash:<file from CGR2010> xmodem:새 ESM 이미지를 xmodem에 복사합니다.

cgr2010-ast03-lab#copy flash:test1 xmodem:test2

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.

11단계. ESM 이미지를 xmodem에 복사한 후:성공적으로 ESM 모듈에 로그인합니다. 

service-module gigabitEthernet 0/0/0 session

12단계. 스위치에서ESM에서 프롬프트를 표시하고 boot 명령을 사용하여 적절한 이미지를 로드합니다.

비밀번호 복구

13단계. dir 플래시 문제:명령을 사용합니다.

Switch#dir flash:
Directory of flash:/

4 -rwx 3423 Jan 1 1970 00:27:29 +00:00 config.text.backup

14단계. 컨피그레이션 파일의 이름을 변경하려면 rename flash:config.text flash:config.old를 입력합니다.

switch: rename flash:config.text flash:config.old

15단계. boot 명령을 실행합니다.

switch: boot
