Hello Vince
Try looking up this command "tftp"
"tftp [host-name | ip-address] {-v vr_name} [-g | -p] [{-l [internal-memory local-"
"file-internal | memorycard local-file-memcard | local-file} {-r remote-file} | {- r remote-file} {-l [internal-memory local-file-internal | memorycard local-file-"
"memcard | local-file]}]" in the EXOS_Command_reference_Guide _15_4 it should start in page 316.
There is a big writeup on using the USB slot. The command reference guide can be downloaded from the main web site
www.extremenetworks.com documentation.
Let me know if this helps or if you have any further questions
Thanks
P
