– Use the ping command to verify connectivity to the remote server. Command-Use the following commands to prepare for and install the new software:.– Remotely-Images are in a remote location and you specify the destination using the remote server parameters and the filename to be used locally. – Locally-Images are locally available on the switch. Retrieve compatible images in one of two ways:.– If you specify a different system image, ensure that it is compatible with the running kickstart image. – If the kickstart image is not specified, the switch uses the current running kickstart image.

Software image-Ensure that the specified system and kickstart images are compatible with each other as follows:.The switch and the remote server must be in the same subnetwork if you do not have a router to route traffic between subnets. Ensure that the switch has a route to the remote server. Power interruptions can corrupt the software image.Ĭonfigure the IPv4 address or IPv6 address for the 10/100/1000 BASE-T Ethernet port connection (interface mgmt0). Hardware-Avoid power interruptions during an installation procedure.Bootflash can be busy due to open or active SFTP session, file operation, and so on. Bootflash-During ISSU, bootflash must be free.Also, run the show system internal flash command to check that the threshold limit for the filesystems /bootflash/mnt/pss /var/tmp and /var/sysmgr are met. The internal bootflash requires approximately 200 MB of free space. Space-Verify that sufficient space is available in the location where you are copying the images.You cannot configure a switch during an upgrade. Ensure that everyone who has access to the switch or the network is not configuring the switch or the network during this time. Scheduling-You should upgrade when your network is stable and steady.You should perform module installations or removals only before or after an upgrade. Topology-You should make topology changes such as Spanning Tree Protocol (STP) that affect zoning or Fabric Shortest Path First (FSPF) before you perform an upgrade.
