4.4.5 Support for NetRAIN Network Interface
Tru64 UNIX now provides support for detecting the physical loss of network
connectivity, and subsequent automatic switchover to a working network
interface. This feature is called Redundant Array of Independent Network
adapters (NetRAIN).
NetRAIN uses two or more network interfaces to provide redundancy.
Although only one interface at a time is actually used for communication, all
interfaces are monitored to ensure that trafficisflowing on each. If the
interface currently being used should suffer a loss of connectivity, NetRAIN
will switch network traffic to the next working interface. All the context of
the previous interface is maintained: hardware address, multicast addresses,
and so on.
NetRAIN is configured through extensions to the ifconfig command. It
also features a programming interface via ioctl() for manual program
control.
NetRAIN supports the following network adapters:
• DE435 (PCI/Ethernet)
• DE500-XA (PCI/Fast Ethernet)
• DE500-AA (PCI/Fast
• DE504-AA (Four-port/Fast Ethernet)
• DE500-BA (PCI/Fast Ethernet)
• DEFEA (EISA/FDDI)
• DEFPA (PCI/FDDI)
• DE422 (EISA/Lance Ethernet)
• DE425 (EISA/Ethernet)
• DEMFA (XMI/FDDI)
• DEMNA (XMI/Ethernet)
• ATM Emulated LAN (ELAN) interface (any supported ATM adapter)
TruCluster Software users should consult the Software Product Descriptions
(SPDs) for TruCluster Software for a list of network interfaces supported by
that product.
For more details about NetRAIN, see the Network Administration guide and
the nr(7) and ifconfig(8) reference pages.
