Hi Mate,
There is not this option in the NXOS cli.
But you can run bash on Nexus 9000, and from there you can run ssh:
switch# configure treminal
switch(config)# feature bash-shell
switch# run?
run Execute/run program
run-script Run shell scripts
switch# run bash?
bash Linux-bash
switch# run bash
bash-4.2$ ssh -p 922 username@x.x.x.x
Cheers.
