Fabric Engine 8.10 automatically upgrades the boot loader (uboot) image on 5420 Series to version 2.3.2.15.
The new uboot image for 5420 Series significantly reduces memory utilization.
When you activate the 8.10 software image, the uboot default information is updated and the switch boots with it. After the reboot, the alternate uboot information is updated.
In Release 8.10, the spbm-node-scaling boot config flag is enabled by default.
The warning message about enabling spoof-detect on both SMLT aggregation switches no longer displays when you enable spoof-detect on a port.
