{
{      This subcommand provides the operator with the capability to change
{ the state of the local host and/or any of the remote hosts defined in
{ the currently active RHFAM configuration. This command is valid only while
{ the RHFAM system task is active. The OFF state of a host is lost when
{ the RHFAM system task is de-activated. Changing the state of any host to
{ OFF will inhibit the establishment of subsequent connections between the
{ local host and the corresponding remote host. Changing the state of the
{ local host to OFF has an additional impact. Subsequent connects from any
{ remote host are inhibited. Use of the keyword ALL when specifying the host
{ physical identifier along with the OFF state is an effective way of idling
{ all traffic to or from the local host.
{
{      The caller must have NETWORK_OPERATION capability specified in the
{ validation file, or be the system job in order to use this command.
