[Step-by-Step] "시스코 스위치 OS 업그레이드" by FTP 서버

안녕하세요~

 

오늘은 FTP 서버를 사용해서 "시스코 스위치 OS 업그레이드" 하는 방법을 올리려 합니다. 

 

보통 "TFTP 서버"를 많이 사용하실텐데요. 어느 방법이든 OS image 파일을 스위치로 업로드만 하시면 아주 간단히 진행할 수 있습니다.

 

Step 1. FTP 서버 준비 

(저는 알FTP 서버를 사용했습니다.)

 

위 설정 상으로는 "C:\"에 OS image를 올려두시면 되겠죠?

 

Step 2. 스위치에서 OS 다운로드

OA-SW#copy ftp://admin:admin@10.70.3.198/cat9k_iosxe_npe.17.12.04.SPA.bin flash: Destination filename [cat9k_iosxe_npe.17.12.04.SPA.bin]? Accessing ftp://*:*@10.70.3.198/cat9k_iosxe_npe.17.12.04.SPA.bin ...!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Step 3. 파일 상태 확인

OA-SW#dir Directory of flash:/ 262145  drwx             4096   Dec 6 2024 11:01:00 -04:00  .installer 196639  -rw-       1303572959   Dec 6 2024 11:00:39 -04:00  cat9k_iosxe_npe.17.12.04.SPA.bin 196625  -rw-          5242880   Dec 6 2024 06:35:21 -04:00  ssd 196611  -rw-          2097152  Nov 25 2024 09:59:08 -04:00  nvram_config_bkup 196610  -rw-          2097152  Nov 25 2024 09:59:08 -04:00  nvram_config 196635  -rw-                0  Aug 30 2024 06:25:54 -04:00  dope_hist 196633  -rw-            16999  Aug 30 2024 06:25:54 -04:00  rdope_out.txt 196634  -rw-               89  Aug 30 2024 06:25:53 -04:00  rdope.log

 

"cat9k_iosxe_npe.17.12.04.SPA.bin" 파일이 업로드 되어 있는 것을 확인할 수 있습니다.

 

Step 4. 신규 Image 설치

OA-SW#install add file flash:cat9k_iosxe_npe.17.12.04.SPA.bin activate commit install_add_activate_commit: START Fri Dec  6 11:17:06 GMT 2024 install_add_activate_commit: Adding PACKAGE install_add_activate_commit: Checking whether new add is allowed .... --- Starting initial file syncing --- Info: Finished copying flash:cat9k_iosxe_npe.17.12.04.SPA.bin to the selected switch(es) Finished initial file syncing --- Starting Add --- Performing Add on all members   [1] Add package(s) on switch 1   [1] Finished Add on switch 1 Checking status of Add on [1] Add: Passed on [1] Finished Add Image added. Version: 17.12.04.0.4826 install_add_activate_commit: Activating PACKAGE gzip: initramfs.cpio.gz: decompression OK, trailing garbage ignored Following packages shall be activated: /flash/cat9k-wlc.17.12.04.SPA.pkg /flash/cat9k-webui.17.12.04.SPA.pkg /flash/cat9k-srdriver.17.12.04.SPA.pkg /flash/cat9k-sipspa.17.12.04.SPA.pkg

 

Step 5. 스위치 자동 Restart

This operation may require a reload of the system. Do you want to proceed? [y/n] y --- Starting Activate --- Performing Activate on all members   [1] Activate package(s) on switch 1     --- Starting list of software package changes ---     Old files list:       Modified cat9k-cc_srdriver.17.06.04.SPA.pkg       Modified cat9k-espbase.17.06.04.SPA.pkg       Modified cat9k-guestshell.17.06.04.SPA.pkg . . . .

SUCCESS: install_add_activate_commit  Fri Dec  6 11:31:40 GMT 2024   PID TTY          TIME CMD

 

Step 6. 스위치 재시작 후 OS Version 확인, 완료!!

아주 간단하죠? ^^
