kmgmt-3025-cisco-business-mobile-app-overview

Objective

The firmware is the program that controls the operation and functionality of the switch. It is the combination of software and hardware that has program code and data stored in it in order for the device to role.

Upgrading the firmware improves the operation of the device, which could provide enhanced security, new features, and issues fixes. This process is also necessary if you encounter the following:

Frequent network disconnection or intermittent connectedness using the switch
Slow connexion

Yous can upgrade the firmware of the switch through its web-based utility or through the Control Line Interface (CLI).

This article aims to show you lot how to upgrade the firmware on your switch through the CLI. If you are a beginner, you may want to upgrade the firmware using the Graphical User Interface (GUI). This article covers the task of having to update the boot code. How to Upgrade Firmware on 200/300 Serial Switches

Here is a second article that that explains how to upgrade the firmware using the web-based utility. Upgrade Firmware on a Switch.

Applicable Devices | Software Version

Sx300 Series | ane.iv.7.06 (Download latest)
Sx350 Series | 2.2.eight.04 (Download latest)
SG350X Serial | 2.two.8.04 (Download latest)
Sx500 Series | 1.four.vii.06 (Download latest)
Sx550X Series | two.2.viii.04 (Download latest)

Upgrade Firmware on a Switch through the CLI

Download the Latest Firmware

In preparation for the upgrade process, download first the latest firmware of the switch. Follow the instructions below:

Step 1. Select the link for the latest version of firmware using the appropriate link above.

Pace 2. Choose the exact model from the drop-downward listing.

Footstep three. Click Switch Firmware.

Step 4. The page will bear witness the latest firmware version of your switch and the size of the file. Click the Download button.

Brand certain to copy the file to your TFTP folder.

In this example, PuTTY is used as the terminal emulator application.

Step 2. In the PuTTY Configuration window, cull Serial as the Connexion type and enter the default speed for the serial line which is 115200. Then, click Open.

Pace 3. Log in to the switch CLI using your own User Proper name and Countersign.

The default username and countersign is cisco/cisco. In this instance, the default User Name cisco, and a personal password is used.

Footstep iv. Once you are on the CLI, enter the privileged exec manner and check the firmware version your switch is currently using every bit well as the location where the image is installed, and other data by inbound the following:

CBS350#sh ver

In the example prototype beneath, the switch used is the SG350X and the following information is shown:

The switch is running firmware version 2.2.5.68
The image is installed in the wink directory
The MD5 hash string
The time and appointment the paradigm is loaded to the switch

Footstep 5. Browse through your TFTP folder and run the TFTP server in the groundwork in training for the upgrade procedure.

Stride 6. Upload the latest firmware file from your TFTP binder to the switch by inbound the following:

CBS350#boot arrangement tftp://192.168.100.108/prototype/image_tesla_Sx250-350_Sx350X-550X_2.ii.8.4.bin

Note: In this case, the IP address of the TFTP server used is 192.168.100.108.

Step 7. Wait until the folio shows that the operation has been completed.

Step viii. (Optional) To verify that the new image file has been successfully loaded, check your switch firmware data again past entering the following:

CBS350#sh ver

Step 9. Check the firmware information. The page should show both the old and new image files merely should signal that the old image file will exist inactive after reboot and the new image file will be agile after reboot.

Footstep x. Reboot the switch past entering the post-obit:

CBS350#reload

Pace 11. Enter Y in the message prompt to continue.

Stride 12. Await for a few minutes while the arrangement is shutting down and rebooting.

Step 13. Once the organisation has rebooted, log in to the switch again.

Step 14. Verify the if the new epitome file is now agile past entering the following:
