I have a few X480 extreme switches here at Intel and want to upgrade the OS on them
I already got summitX480-220.127.116.11-patch1-14.xos from extreme website but during downloading it to switch (after tftpd32 finished its job) switch says "Error: File could not be unwrapped"
I thought maybe there is an upgrading step probably to a lower version first that I'm missing
Can someone help me out?
Except, it sounds like you already did this... check that the MD5/SHA256 sum is correct on that file.
