you should be able to use the vifptarget command to set the host as your target so you won't have to type in the credentials each time.
vifptarget -set hostname
Then you can issue commands directly to that host.
in which case this poster will be helpful

otherwise you would just issue the command and specify the host after the command;

obviously it's a lot easier if you add it as a target and run commands to it that way.
