SLX-OS Firmware Download with Maintenance Mode

With the firmware download with maintenance mode feature, you can download firmware on one or more devices in the IP Fabric with the smallest possible disruption to data path traffic. Both CLOS and Non-CLOS fabrics are supported. Maintenance mode feature is supported only on SLX devices running SLXOS 20.1.x.

New features for this release include:

• Firmware download with maintenance mode
  • Asynchronously launched operation
  • Sanity and pre-install script check
  • Configuration to set convergence timeout, enable, and disable
  • Persist the running configuration so that device configuration and maintenance mode configuration is preserved after reboot
  • Firmware download with no commit option to allow restoration of firmware to the previous version
  • During maintenance mode, no configurations will be allowed on the device.
• Firmware host registration, with support for register, update, delete, and list operations
• Firmware download preparation, with support for add, remove, and list operations
• Firmware download execute to start firmware download with maintenance mode asynchronous operation
• Firmware download show, to display a table of devices in the Fabric and their corresponding status

Limitations

• Switch firmware must be SLX-OS 20.1.x or later to support firmware download with maintenance mode for a hitless firmware upgrade.
• This feature assumes an existing host which contains SLX-OS firmware images ready to be downloaded from.
• This feature should not be launched on the same switch where EFA TPVM is deployed.
