SysKonnect FDDI PCI Adapters

UnixWare 7 supports these FDDI PCI adapters:

• SK-NET FDDI PCI series adapters

For most PCI adapters, no special setup procedure is required. Consult your hardware documentation for more information.

For advanced configuration of these adapters, the Network Configuration Manager prompts you for:

• USER Data [USERDATA,s]:
  User data to be passed to the SMT.

• PMF password [PMFPASSWD,s]:
  Parameter Management Frame (PMF) password for the adapter. A nonzero PMF password enables authorization checking of the adapter for remote change requests. A PMF password of 0 disables the authorization checking of the adapter. The PMF password consists of 16 hexadecimal digits. Default value is 0.

• SMT T-Req [TREQ,n]:
  This parameter provides local write access to the T-Req value that is registered as fddiMAC 51 in the SMT Standard. The value for T-Req is specified in milliseconds. The valid range is between 5 ms and 165 ms. If an invalid value is specified, the default value for T-Req (165 ms) is used.

• SMT TVX lower bound [TVX,n]:
  This parameter provides local write access to the TVX attribute registered as fddiMAC 54 in the SMT Standard. This attribute provides local control of the recovery time from transient ring errors. The value for TVX is specified in microseconds. The valid range is between 2500 us and 10000 us. The default value is 2700 us.
  
  NOTE: Due to hardware limitations the upper value for the TVX attribute is restricted to 5200 us. It is recommended to set a value below this limit.

• Alternate MAC/SMT Address [MACADDR,s]:
  This parameter specifies the alternate MAC address that is used instead of the adapter's default factory address. A valid MAC address consists of 12 hexadecimal digits. The default value is none, in which case the adapter's factory address is used. The valid address format is: xx:xx:xx:xx:xx:xx or x:x:x:x:x:x or xx:x:xx:x:x:x::

• SBA Payload [SBAPAYLOAD,n]:
  This parameter defines the requested synchronous bandwidth for manual static allocations. The valid range is between 0 and 1562 bytes per 125 us. For example : if the required bandwidth is 1 MBits/s (125,000 Bytes/s) , the value of the payload is 125,000 * 125E-6 = 15.625 round up to 16. The default value is zero which means no synchronous bandwidth is used. The user should define the amount of bandwidth to be able to send synchronous frames. If this parameter is not specified, the keywords SBA OverHead, MaxTneg, MinSegment - Size and SBA Category take no effect. The end station supports either the static allocation model if the requested payload is specified by the parameter SBA_Payload or the dynamic allocation model. This means that the required synchronous bandwidth is allocated by a multimedia application. If a multimedia application can dynamically allocate bandwidth, the parameter SBA PayLoad should not be specified.

• SBA Overhead [SBAOVERHEAD,n]:
  This parameter defines the requested overhead for static allocations. The valid range reaches from 0 to 5000 bytes. If a value is specified which is outside the limits, the upper/lower limit is taken. The default value is 50 bytes. This parameter has no effect, unless the parameter SBA PayLoad is specified.

• MaxTneg [MAXTNEG,n]:
  This parameter defines the maximum token rotation delay that is acceptable to the application(s) using synchronous bandwidth. The valid range is between 5 ms and 165 ms. The default value is 25 ms. This parameter takes no effect unless the parameter SBA PayLoad is specified.

• MinSegmentSize [MINSEGMSIZE,n]:
  This parameter defines the minimum synchronous segmentation size. The value corresponds to the number of bytes that will be transmitted on a per token opportunity. The valid range is between 1 and 4478 bytes. The parameter takes no effect unless the parameter SBA PayLoad is specified.

• SBA Category [SBACATEGORY,n]:
  This parameter defines the session ID of the SBA Category for the static allocation. The valid range is between 0 and 65535. This parameter takes no effect unless the parameter SBA PayLoad is specified.

• Syncronous Transfer Mode [SYNCHTXMODE,n]:
  This parameter defines the synchronous transmission mode. The default value is "SPLIT" that is represented by a numeric value of 0. This means that only synchronous packets will be transmitted via the synchronous queue. The other value is "ALL" that is represented by a numeric value of 1. This means that all LLC packets received from upper protocol layers are transmitted via the synchronous queue. The keyword takes no effect unless the end station support is able to get the required synchronous bandwidth from the SBA.

• SBA Available [SBAAVAILABLE,n]:
  The parameter specifies the maximum synchronous bandwidth in percent that is available for the primary path. The valid range is 0-100. The default value is 50.

• Trace ring state [TRACE_CMD:n]:
  The driver supports a configuration parameter that allows the customer to trace certain events in the network driver.
  
  The only event that can be traced is changing the ring state. If the customer sets the configuration parameter to 8 (bit 3) the driver will display syslog messages both to the system log and the system console if the ring state has been changed e.g. 'ring down','wrapped'... The default value is 0 that means no tracing is active.

This driver release supports configuration parameters that may not appear in the driver's Advanced Options Menue.

The following shows a list of all user configurable configuration parameters that may or may not be displayed in the Advanced Options Menue'.

However each of the configuration parameter can be specified with the resmgr command manually: resmgr -k <resmgr-key> -p <parameter>,<type> -v <value>

<resmgr-key> - the resource manager key of the network device that can be displayed by: resmgr

<parameter> - the name of the parameter that the network driver expects in the configuration manager database.

<type> - either 's' for a string or 'n' for a numeric value.

<value> - the configuration value either a "string" or numeric value.

Sample: resmgr -k 57 -p USERDATA,s -v "strings_must_not_contain_spaces"

The name in brackets shows the name of the configuration parameter as it is expected in the configuration manager database. 's' and 'n' indicate that the value must be specified as a string or numeric value.

If no or an invalid configuration value is given to the network driver the network driver will always use the default value.
