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:). See System Configuration Supplement: OEM Platforms for detailed information about the use of the vb interface on Alpha VME systems, includ- ing the following topics: VMEbus backplane (vb) network overview Configuring vb network nodes Modifying vb driver attributes Modifying vba_vipvic adapter attributes Modifying vba_univ adapter attributes Examples Related ioctl commands Diagnostic messages Errors RELATED INFORMATION
