모델: cisco Nexus9000 C93108TC-FX3P
설정한 비밀 번호를 알 수 없는 경우, 아래와 같은 과정을 거쳐 새로 설정한다.
1. 스위치와 콘솔케이블을 연결한다. 속도는 9600bps
2. 부팅이 시작될 때 Ctrl+C 키를 눌러서 ‘loader > ‘프롬프트로 진입한다.

3. cmdline recoverymode=1 을 입력한다.
loader > cmdline recoverymode=1
4. dir 명령으로 부트 이미지를 확인한다. 보통 .bin 확장자를 가진다.
loader > dir bootflash:: lost+found .rpmstore evt_log_snapshot .swtam eem_snapshots virtual-instance virtual-instance.conf virt_strg_pool_bf_vdc_1 scripts 20230118_041926_poap_3056_init.log platform-sdk.cmd nxos.9.3.5.bin home 20230118_043549_poap_2598_init.log 20230216_020623_poap_2373_init.log poap_retry_debugs.log 20230310_073030_poap_2375_init.log
5. 위에서 확인 한 부트 이미지로 부팅을 한다. 위에서 확인한 파일은 nxos.9.3.5.bin 이다.

6. 부팅이 완료되면 switch(boot)# 프롬프트가 보인다. 이때, admin-password 명령으로 비밀번호를 설정한다.
switch(boot)# conf t Enter configuration commands, one per line. End with CNTL/Z. switch(boot)(config)# admin-password Cisco123! WARNING! Enabling local authentication for login through console due to password recovery switch(boot)(config)# exit
7.load-nxos 명령으로 스위치를 재부팅 한다.
