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 net‐
work 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) soft‐
ware support the vb driver as well as communication between these sys‐
tems 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/syscon‐
figtab 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:).
