Simplified Upgrade is a single operation that performs a full system upgrade of all the images. The routing and switching functionalities will continue to operate until TOE is reloaded after upgrade is done. It can be as simple as one command from the CLI. However using the copy tftp system command with the new all images and manifest parameters introduced in R05.3.00, you can upgrade your system by issuing only one command.
Use the following command to perform the simplified switch upgrade:
Enable TFTP in FIPS CC mode :
fips policy allow tftp-access
For Extreme NetIron MLX Series devices :
copy tftp system all <Ip addres for the tftp server> manifest <manifest text file name>
The firmware packages are signed using a 2048-bit RSA key with SHA-256 during firmware build and is verified during firmware installation using a public key file on the switch. The digital signature contained within the firmware package is the definitive method to determine the validity of the firmware during download and installation. The installation begins after a successful verification, and an error message displays upon unsuccessful verification.
The process is optimized by introducing a version-check of the images to determine whether it is necessary to download/upgrade the image or not. This simplified upgrade method greatly reduces the possibility of having incompatible interface modules due to incompatible image versions.
The command can be issued to download images from either of the following:
Use the all-images parameter to upgrade the management and interface boot, monitor, and application images, as well as all interface and management FPGA images. Since many of these images are not required to be upgraded for each release and doing so can be time consuming, you can upgrade the management and interface monitor and application images, as well as the combined FPGA images only by omitting the all images parameter.
The default behavior is that the all images parameter is not specified.
Note
Management and interface boot images and individual boot images are generally not required to be upgraded and customers are not recommended to upgrade them, unless it is explicitly stated otherwise in release notes. Copying management interface FPGA images may temporarily affect time-sensitive protocols.Note
For simplified upgrades on the NetIron CER devices, the pbif_mero installation in simplified upgrade will fail and device will need to be reloaded. After all images are installed using Simplified upgrade, the pbif will need to be installed manually, and the device will need to be reloaded again.Note
For a simplified upgrade from R05.6.00d to R05.7.00a, b, or c, the boot image is not upgraded as part of the manifest file due to it not being a necessary upgrade. The 5.6.00 boot image is compatible with the 5.7.00 version. When a show version is run on the Extreme MLX device, it will show the boot image as version 5.6.00, but the Extreme MLX device will be fully functional, and have the full update of 5.7.00c. You may still choose to manually upgrade to the R05.7.00 boot image. Both use cases are acceptable and will function properly on the Extreme MLX device.
