Ophir,
That command from step 7 "show ports type" or "port..." is not recognized on my sx1012. I ran some of the other ones that are mentioned in that link that work:
[standalone: master] (config) # show system capabilities
Ethernet: Supported, Full L2, L3
Ethernet Max licensed speed: 40Gb
[standalone: master] (config) # show system profile
eth-single-switch
[standalone: master] (config) # show port
% Unrecognized command "port".
Type "show ?" for help.
[standalone: master] (config) # show ports
% Unrecognized command "ports".
Type "show ?" for help.
The only option that 'port' gives me is "load-balance"
