Name
       fza - DEFZA FDDI Network Interface

Syntax
       device fza0 at ibus? vector fzaintr

Description
       The  interface  is  a  high  speed  TURBOchannel  bus to a 100 Mbit/second Fiber Distributed Data Interface (FDDI) timed token ring network
       adapter.  The interface allows the host system to be an FDDI single attachment station.

       The host's Internet address is specified at boot time with an SIOCSIFADDR ioctl.  The interface employs	the  address  resolution  protocol
       described in to map dynamically between Internet and FDDI addresses on the local network.

       The maximum frame size for the interface is 4500 bytes, which is substantially larger that the 1500 bytes maximum packet size of the Ether-
       net interfaces. The interface does not support the BSD trailer encapsulation, which is specific to the VAX architecture.

       The SIOCRPHYSADDR ioctl can be used to read the physical address of the DEFZA adapter. The physical address of the DEFZA adapter can not be
       changed.

       The  SIOCADDMULTI  and  SIOCDELMULTI  ioctls  can  be  used  to	add  or delete multicast addresses.  The DEFZA supports up to 64 multicast
       addresses.

       The SIOCRDCTRS ioctl can be used to read the FDDI driver counters.  The DEFZA adapter status and characteristics can also be  read  through
       this ioctl by providing a FDDI_STATUS flag . The argument to this ioctl is a pointer to a counter or status structure, found in <net/if.h>.

       The SIOCENABLBACK and SIOCDISABLBACK ioctls can be used to enable and disable the interface loopback mode, respectively.

       The SIOCEEUPDATE ioctl can be used to update the adapter's firmware.

       The SIOCIFRESET ioctl can be used to reset the adapter.

Diagnostics
       Diagnostic error messages contain information provided by the driver. For example:

       fza%d: fzaprobe selftest failed
       The DEFZA adapter did not pass the power-up selftest during autoconfiguration.
       fza%d: port init failed
       The DEFZA adapter cannot be initialized.
       fza%d: port in the Halt State -> CNS hardware fault
       The DEFZA adapter went to the Halt state because of an adapter firmware fault.
       fza%d: LINK unavailable
       The network link went down which means that the station is not on the FDDI ring.
       fza%d: Ring Init Received
       A Ring Initialization unsolicited event has been received from the fza%d interface.

NAME
tra - DETRA 4 Mb/s or 16 Mb/s Token Ring interface SYNOPSIS
config_driver tra Entry in the system configuration file DESCRIPTION
The tra interface is a Token Ring TURBOchannel adapter that can operate at 4 Mb/s or 16 Mb/s. The adapter uses a TMS380 chip to implement the Token Ring protocol. The host's Internet address is specified at boot time with a SIOCSIFADDR ioctl. Also the speed at which the interface should operate can be specified using the SIOCSMACSPEED ioctl. The default speed at which the interface will try and enter the ring is at 16 Mb/s. The other supported speed is 4 Mb/s. ifconfig(8) describes how to set the speed of the interface by using the speed option. The maximum MAC frame size supported by the driver on a 4 Mb/s Token Ring network is 4136 and for a 16 Mb/s network it is 8232. The SIOCRPHYSADDR ioctl can be used to read the physical address of the DETRA adapter. The SIOCADDMULTI and SIOCDELMULTI ioctls can be used to add or delete functional addresses. The SIOCRDCTRS ioctl can be used to read the Token Ring driver counters. The DETRA adapter status and characteristics can also be read through this ioctl by providing one of the following options: Reads the counters Reads the characteristics Reads the RFC 1231 mib entry Reads the RFC 1231 status entry The driver does not support reporting information on the timer statistics as defined in RFC 1239. The argument to this ioctl is a pointer to a counter or status structure, ctrreq, found in <net/if.h>. The structures defining the Token Ring counters and status maintained can be found in <netinet/if_trnstat.h>. The SIOCENABLBACK and SIOCDISABLBACK ioctls can be used to enable and disable the interface loopback mode, respectively. The driver enables internal loopback only. The SIOCIFRESET ioctl can be used to reset the adapter. EXAMPLES
To obtain the physical address of the adapter, use the SIOCRPHYSADDR ioctl as in the following program example: #include <stdio.h> /* standard I/O */ #include <errno.h> /* error numbers */ #include <sys/socket.h> /* socket definitions */ #include <sys/ioctl.h> /* ioctls */ #include <net/if.h> /* generic interface structures */ main() { int s,i; static struct ifdevea devea; /* Get a socket */ s = socket(AF_INET,SOCK_DGRAM,0); if (s < 0) { perror("socket"); exit(1); } strcpy(devea.ifr_name,"tra0"); if (ioctl(s,SIOCRPHYSADDR,&devea) < 0) { perror(&devea.ifr_name[0]); exit(1); } printf("Address is "); for (i = 0; i < 6; i++) printf("%X ", devea.default_pa[i] & 0xff); printf(" "); close(s); } To reset the adapter, use the SIOCIFRESET ioctl as in the following program example: #include <stdio.h> /* standard I/O */ #include <errno.h> /* error numbers */ #include <sys/socket.h> /* socket definitions */ #include <sys/ioctl.h> /* ioctls */ #include <net/if.h> /* generic interface structures */ main() { int s; struct ifreq data; /* Get a socket */ s = socket(AF_INET,SOCK_DGRAM,0); if (s < 0) { perror("socket"); exit(1); } strcpy(data.ifr_name,"tra0"); if (ioctl(s,SIOCIFRESET,&data) < 0) { perror("SIOCIFRESET:"); exit(1); } close(s); } ERRORS
Diagnostic messages contain information provided by the tra driver and the adapter. The following messages contain information about the adapter's state, and are printed on the console. Each message begins with the adapter identification, including the number of the adapter: The driver received an adapter check interrupt. The reason for the interrupt is displayed. The driver could not get an aligned address for the System Status Block (SSB). (See Texas Instruments, TMS380 Second-Generation Token Ring User's Guide for an explanation of SSB.) The Bring Up Diagnostics (BUD) failed. The value of the command/status register and the reason for the failure are displayed. The driver received an unknown interrupt. An error while trying to write out the initialization block to the TMS380 Token Ring chip. The value of the command/status register is displayed in hexadecimal. The MAC_CLOSE command returned an unknown status to the driver. A request to close the MAC was previously issued to the adapter. A request to open the MAC was previously issued to the adapter. The command to open the MAC was rejected. The reason is displayed. The driver opened the adapter into the ring at the speed indicated. Only two speeds are supported - 4 Mb/s and 16 Mb/s. If either message is displayed, reset the adapter by issuing the following commands: % ifconfig tra0 down % ifconfig tra0 up If the message persists, an error is occurring while transmitting and receiving packets. You will need to investigate the error. The status of the ring. The driver has taken the adapter off the ring. A timeout occurred while waiting for the MAC_READ_ERROR_LOG command to complete. A timeout occurred while trying to close the MAC; the interface is down. A timeout occurred while waiting for the MAC_OPEN command to complete. RELATED INFORMATION
