NAME

       vb, sys_attrs_vme_vba - VMEbus backplane Ethernet interface

SYNOPSIS

       controller vb0 at vba0

DESCRIPTION

       The  VMEbus  backplane (vb) interface provides access to an Ethernet network through the VMEbus backplane driver, which acts as an Ethernet
       Datalink Layer driver.  This interface allows VMEbus-based systems to communicate directly over the VMEbus to other VMEbus-based systems on
       the same backplane, or on other Ethernet connected systems outside the backplane through a gateway node on the backplane.

       Both  the  Tru64  UNIX  and VxWorks for Alpha (Version 3.1 or higher) software support the vb driver as well as communication between these
       systems on the same backplane.  The Tru64 UNIX vb driver is supported on AXPvme and Alpha VME SBCs and Alpha VME 2100 systems.

       The VMEbus backplane interface requires you to modify the /etc/sysconfigtab file on your AXPvme or Alpha VME system in order  to  configure
       the  vb driver and to map VMEbus windows for the system.  Mapping the VMEbus windows on one node requires knowledge about every node in the
       vb network.

									  Note

       Do not modify any vme_vba kernel subsystem attributes.  To configure a vb network node, you modify attributes of the vb	driver	(vb:)  and
       the system's VMEbus adapter (vba_vipvic: or vba_univ:).
