Identifies an adapter located in slot 5 of an I/O expansion drawer. The
drawer is the one connected to the asynchronous expansion adapter
located in slot 8 of the optional I/O bus in the CPU drawer.
Transmit Queue Size
Transmit Queue size: indicates the number of transmit requests (frames)
that can be queued up by the device driver prior to being added to the
adapters (hardware) transmit queue.
Valid values range from 3 to 250. The default value is 30.
PCI Fix Value
Not used.
TVX lower bound
Provides local write access to the TVX attribute, registered as fddiMAC 54
in the SMT Standard.
The attribute provides local control of the recovery time from transient ring
errors. The value for TVX Lower Bound is specified in microseconds. The
value range is 2500 µs ... 10000 µs. If a value outside the limits is specified,
the upper/lower limit will be taken. If no value is specified, the default value
2700 µs is used.
MAX T–Req
Provides local write access to the T–Req attribute, registered as fddiMAC
51 in the SMT Standard. T–REQ specifies the requested target rotation
time (TTRT) for this station and directly affects ring utilization. The value for
TReq is specified in milliseconds. The value range is 5 ms ... 165 ms. If a
value outside the limits is specified, the upper/lower limit will be taken. If no
value is specified, the default value 10 ms is used.
Enable Alternate MAC/SMT Address
Setting this attribute to the yes value indicates that the address of the
adapter, as it appears on the LAN is the one specified by the Alternate
MAC/SMT Address attribute. If you specify the no value, the unique adapter
address written in a ROM on the adapter is used. The default value is no.
Alternate MAC/SMT Address
Allows the adapter unique address, as it appears on the LAN, to be
changed. The value entered must be a FDDI address in canonical form of
12 hexadecimal digits (6 bytes) and have the group address bit set to 0 and
the local address bit set to 1. The group address bit is the high order bit of
the high order byte; the local address bit is the second highest order bit of
the high order byte. The address must not be the same as any other FDDI
address on the ring. This field has no effect unless the Enable Alternate
MAC/SMT Address attribute is set to the yes value, in which case this field
must be filled in. To change the Alternate MAC/SMT Address, enter 0x
followed by the 12 digit address. All 12 hexadecimal digits must be entered.
The valid values range from 0x400000000000 through 0x7fffffffffff. The
default value is 0x400000000000.
PMF password If this attribute has a non-zero value, it defines the password that all remote
PMF (Parameter Management Frame) requests must provide to change
attributes within the adapter. The value for pmf_passwd is 8 ASCII
characters long and not case sensitive since lower case letters will be
converted to upper cases. Password protection can be disabled by setting
this attribute to all zeros (default), or by not specifying a PMF Password.
USER Data
This attribute provides local write access to the User Data parameter in the
SMT MIB, registered as fddiSMT 17 in the SMT Standard. The User Data
must be an ASCII string for compliance with the FDDI SMT Standard. It can
be 32 bytes long and can contain any user data; for example station name,
location, etc.
