Cisco C93180 switch upgrade guidelines

When using optical modules on a switch, the same switch model may yield different optical module test results with different system versions. This is because different system versions have varying optical module compatibility requirements. To promptly identify or resolve module compatibility issues and improve module adaptability to the device, users can select the appropriate switch system version provided by the manufacturer based on their needs.

The following is a method for upgrading the system version of a Cisco switch using TFTP, based on a specific case:

I. Information/Material Preparation

• TFTP software (32-bit/64-bit, matching the computer's operating system);

• Switch system version file (download from the official website: https://www.cisco.com/c/en/us/support/ios-nx-os-software/index.html ; this upgrade uses NXOS.9.3.6.bin);

• Network cable;

• Switch (Cisco Nexus9000 C93180YC-EX) and computer.

II. Upgrade Steps

1. Configure the Switch Management Port IP

Set the IP address of the switch's management port to be in the same network segment as the interconnected computer (the computer IP used in this upgrade is 192.168.30.16):

cisco(config)# interface mgmt 0

cisco(config-if)# ip address 192.168.30.100 255.255.255.0

2. Configure the TFTP Source Port

Use the switch's management port as the TFTP source port: cisco(config-if)# ip tftp source-interface mgmt 0

3. Launch and Configure TFTP Software

• Current Directory: Fill in the folder path on the computer where the upgrade system version file is stored;

• Service Interfaces (Server Address): Fill in the local IP address of the computer (192.168.30.16 in this case).

4. Test Connectivity Between Switch and TFTP Server

Ping the computer's IP (TFTP server IP) on the switch terminal to verify connectivity: cisco(config)# ping 192.168.30.16 vrf management // Ping the TFTP server IP via the management VRF

5. Copy the System Version File to the Switch Bootflash

Transfer the system file from the TFTP server to the switch's bootflash directory: cisco(config)# copy tftp://192.168.30.16/nxos.9.3.6.bin bootflash:

6. Verify File Upload Success

List files in the bootflash directory to confirm the system file is uploaded successfully: cisco# dir bootflash:

7. Configure the Boot System and Save Settings

Set the upgraded system file as the boot file and save the configuration (note: the file name must match the uploaded version):

cisco(config)# boot nxos bootflash:nxos.9.3.6.bin // Correct the file name to match the uploaded version (9.3.6) cisco(config)# copy running-config startup-config // Save the running configuration to startup-config

8. Reboot the Switch to Apply Upgrade

Execute the reboot command and confirm to restart the switch:

cisco# reload

This command will reboot the system(y/n)? [n]y // Enter "y" to confirm reboot

9. Confirm the Upgraded System Version

After the switch restarts, check the currently running system version to verify the upgrade is successful: cisco# show system

The output will display the current running NXOS version and the corresponding image file name, confirming the upgrade result.
