{
{      This subcommand provides the operator with the capability of changing
{ the state of a local and/or remote network access device(NAD) defined
{ in the currently active RHFAM configuration to ON, OFF, or DOWN (only local
{ NADS may be set DOWN). OFF or DOWN states are not preserved when the system
{ task is deactivated. Changing the state of a local NAD to OFF or DOWN will
{ cause all activity on that device to terminate immediately, in addition,
{ setting a local NAD DOWN subjects the NAD to the local maintenance routines.
{ While the NAD is DOWN, its state may not be changed by this command. The
{ NAD state may be automatically changed to ON if the maintenance routines
{ deem the NAD usable.
{
{      The caller must have NETWORK_OPERATION capability specified in the
{ validation file, or be the system job in order to use this command.
