Leaf Smart System Upgrade (SSU) provides the ability to upgrade the EOS image with minimal traffic disruption.Note: It is possible that SSU shutdown and bootup are not supported in the same image. If a product has shutdown support in image A and bootup support in a later image B, then SSU upgrade cannot be performed from image A to any images earlier than image B, including image A itself. However, upgrading from image A to image B onwards is allowed.

Leaf Smart System Upgrade (SSU) provides the ability to upgrade the EOS image with minimal traffic disruption. To perform the SSU, Spanning Tree Protocol (STP) should either be disabled or configured as MSTP. Meanwhile, all ports should be configured with admin edge ports (i.e., all ports are supposed to connect to host only) and the BPDU guard should be enabled for all edge ports.

There are two types of reload on a switch running EOS, normal reload and Smart System Upgrade (SSU). Scheduled normal reload is supported via ‘reload in’ command, to perform a normal reload after a specified delay. It asks for saving unsaved configuration changes and confirmation in order to schedule the reload. Scheduled SSU is supported via ‘reload fast-boot in’ command. However, after scheduling an SSU reload, if there are unsaved configuration changes, or saved configuration changes which block an SSU reload, the scheduled reload will be aborted at scheduled time.
