       vb,  sys_attrs_vme_vba  - VMEbus backplane Ethernet interface

SYNOPSIS    [Toc]    [Back]

       controller vb0 at vba0

DESCRIPTION    [Toc]    [Back]

       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:).
