I have been trying to upgrade one switch with summitx-22.214.171.124.xos that came out on February 1st and I am having issues. I have 2 of these and one upgraded with no problem. The other will not upgrade via Netsight/Extreme management center and says device busy, please wait. While trying one TFTP method, I get the error "file could no be unwrapped". When I tried the command "download image <ip address> <image_name.xos> primary" I get the error file too large for TFTP protocol. What other method can I use? I cannot use USB, I have tried that. There is no "memorycard" command on the version running on the switch.
