[f-nsp] Script to simplify software upgrade process

[Piper, James]

Hi All,

I'm not sure if I missed something but I haven't found anything in the
documentation that gives a simple list of commands to execute in order
to perform a software upgrade from a TFTP server. In response I wrote
this simple script to parse a software release directory and generate a
file listing the exact commands in order to cut-and-paste onto the
switch. Be good if SNMP could be used instead. Hope it helps someone..

Regards,
James
