X620-16x firmware upgrade error - TFTP error file too large for TFTP protocol

[Phillip_Hood]

I have been trying to upgrade one switch with summitx-21.1.3.7.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 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.

Phillip you can check how much space is being used and how much is available by using the command:

ls

as far as removing unneeded files from here you can use the command:

rm

kind regards,

I am very new to EXOS. Could you point me to the command to see how much space is left or how I can remove an old firmware?
