When it comes to NX-OS upgrade its quite easy and simple compared to the IOS upgrade of Cisco Catalyst Switches or Cisco Routers. Recently we upgraded our Nexus 5000 Series Switches from the NX-OS version 5.0.3 to 5.2.1. In this post let’s see how to upgrade the Nexus 5000 Series Switch step by step.
Login to Cisco Website and download the NX-OS Kick Start and NX-OS System Software files to your TFTP server.
Make sure that Nexus 5000 Switch has the enough space to install the new image files by using NX-OS command “ dir bootflash”. If there is enough space you are free to install the new NX-OS image files.
If there is no enough memory delete old image files using NX-OS command
Delete boothflash: (kickstart image name)
Delete bootflash: (system image name)
SF01-MB-1256-010# delete bootflash:n5000-uk9-kickstart.5.0.3.n1.1a.bin
SF01-MB-1256-010# delete bootflash: n5000-uk126.96.36.199.n1.1a.bin
Copy the new kickstart and system images to the switch bootflash by using a transfer protocol such as ftp, tftp, scp, or sftp. The examples in this procedure use tftp. Use the following NX-OS command to copy the kick start and image file
Make sure that the TFTP server is started
SF01-MB-1256-010# copy tftp bootflash:
Enter the install all NX-OS command to install the new images, specifying the new image names that you downloaded in the Step 1 as shown below
Once all the files are installed the switch will restart and reload with the new Image files.
