Upgrade the Software

1. Enter Global Configuration mode:

   enable

   configure terminal

2. If you are using the USB port to transfer files, go to the next step. If you are using FTP or SFTP to download the files, start the FTP daemon on the switch and enable the ftpd flag for FTP or sshd flag for SFTP:
   

   Note

   Start an FTP session from your computer to the switch using the same user name and password used to Telnet or SSH to the switch. Upload or copy the image to the switch.

   boot config flag <ftpd | sshd>

   end

3. Download the files to the switch through FTP or SFTP, or transfer them to the switch through the USB port.
4. Enter Privileged EXEC configuration mode by exiting the Global Configuration mode.

   exit

5. Extract the release distribution files to the /intflash/release/ directory:

   software add WORD<1-99>

   After you enter this command, the switch verifies it has sufficient space to install the new image. If space is not insufficient, the switch checks the total space of the log files. If the total log file space is sufficient for the new image, the switch prompts you to remove log files.

6. Optional: Respond if you see the following prompt:

   Log files need to be removed to have enough space to install the new image.

   Do you want to remove all log files except the current one?

   If your response is affirmative, the switch removes all log files except the currently active file and displays the following message for each file removed: Log file %s was removed

7. Install the image:

   software activate WORD<1-99>

8. Restart the switch:

   reset

   

   Important

   After you restart the system, you have the amount of time configured for the commit timer to verify the upgrade and commit the software to gold. If you do not commit the software to gold and auto-commit is not enabled, the system restarts with the last known working version after the commit timer has expired. This feature ensures you can regain control of the system if an upgrade fails. By default, auto-commit is enabled.

9. After you restart the switch, enter Privileged EXEC configuration mode:

   enable

10. Confirm the software is upgraded:

    show software

11. Commit the software:

    software commit

    

    Important

    If you disable the auto-commit feature, you must run the software commit command manually before the commit timer expires to commit the new software version, otherwise the system restarts automatically to the previous (committed) version. By default, auto-commit is enabled.
