SCACP$HELP.HLB  —  SET  IP_INTERFACE
    Sets IP interface management priority parameter.

    Format

      SET IP_INTERFACE  ipinterface

1  –  Parameter

 ipinterface[,...]

    Includes one or more specific IP interface, which you can use
    wildcards to specify.

    o  Use the /EXCLUDE qualifier to exclude an IP interface.

    o  Use the SHOW IP_INTERFACE command to display device names.

2  –  Qualifiers

2.1    /EXCLUDE

       /EXCLUDE=(ipinterface1[,...])

    Excludes one or more specific IP interface which you can use
    wildcards to specify.

2.2    /PRIORITY

       /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.

2.3    /SOCKET_RECEIVE

       /SOCKET_RECEIVE=n

    Sets the socket's receive buffer size (in bytes) for the IP BUS. The
    default value is 178432 bytes, which is 128 times the maximum buffer
    size on an IP Channel. 'n' can be a value between 0 and 137035776. To
    reset the socket buffer size for the IP bus, set 'n' to 0. If the
    management provided value is lesser than the initial default, it is
    ignored.

                                 NOTE

       The maximum socket buffer size is limited by tcpip configuration
       and by default it is 1MB. It can be obtained by the following
       command:

         $ tcpip sysconfig -q socket sb_max

       To increase the size of IP bus' receive socket buffer beyond
       1MB, sb_max parameter has to be increased. Refer to "HP TCP/IP
       Services for OpenVMS Tuning and Troubleshooting" for information
       on changing sb_max.

3  –  Example

  SCACP> SET IP_INTERFACE/PRIORITY=3 WE0

      The command in this example sets the management priority for
      device WE0 to 3.
