.Dd February 5, 2019 .Dt EX 4 vax .Os .Sh NAME .Nm ex .Nd Excelan 10 Mb/s Ethernet interface .Sh SYNOPSIS .Cd "ex0 at uba0 csr 164000 vector excdint" .Sh DESCRIPTION NOTE: This driver has not been ported from x 4.4 yet.
p The .Nm ex interface provides access to a 10 Mb/s Ethernet network through an Excelan controller used as a link-layer interface.
p Each of the host's network addresses is specified at boot time with an .Dv SIOCSIFADDR .Xr ioctl 2 . The .Nm ex interface employs the address resolution protocol described in .Xr arp 4 to dynamically map between Internet and Ethernet addresses on the local network. .Sh DIAGNOSTICS l -diag t "ex%d: HW %c.%c, NX %c.%c, hardware address %s." This provides firmware revisions levels, and is expected during autoconfiguration. t ex%d: can't initialize. There was a failure in allocating UNIBUS resources for the device. t "ex%d: configuration failed; cc = %x." The hardware indicated an error when trying to initialize itself. The error code returned is described at length in the device Reference Manual. t ex%d: receive error %b. The hardware indicated an error in reading a packet from the cable. Specific Error bits are provided t ex%d: transmit error %b. The hardware indicated an error in transmitting a packet to the cable or an illegally sized packet. Specific Error bits are provided t ex%d: can't handle af%d. The interface was handed a message with addresses formatted in an unsuitable address family; the packet was dropped. .El .Sh SEE ALSO .Xr arp 4 , .Xr inet 4 , .Xr netintro 4 .Sh HISTORY The .Nm driver appeared in x 4.3 .
