/PRIORITY=n

    Sets the management priority value for the selected interfaces. n
    can be a value between -128 and +127. Suggested values are:

    o  2 to cause devices to be preferred

    o  -2 to exclude devices

                                   NOTE

       Starting with OpenVMS Version 7.3-2, a channel whose
       priority is -128 is not used for cluster communications.
       The priority of a channel is the sum of the management
       priority assigned to the IP interface and the channel
       itself. Therefore, you can assign any combination of channel
       and IP interface management priority values to achieve a
       total of -128.

                                 CAUTION

       If you set the priority of all devices to -128, you totally
       disable use of the IP for cluster communication. This can
       cause the system to CLUEXIT.
