Dear Remo,
yes, this is the new switch OS Aruba is using e.g. in their 6x00 series which replaces HP Procurve style models like Aruba 2530 / 2540.
In a different thread I suggested to use the line below inc/libcli.pm, which should not break compatibility with older firmware versions:
$cmd{'ArubaOS'}{'cfst'} = '^version|Version';
Thanks, Gerhard
