6 Save your revisions to the autoexec.ncf file and, if all NIC configuration has been completed,
reboot the server.
NIC Load
Parameter
Descriptions
slot=
n
Identifies the slot number for the specific NIC currently being configured. This parameter is not necessary if
only a single NIC is installed. If multiple NICs are installed, you can view the list of slot numbers when loading
the driver.
frame=
type
Defines the frame type being used by this load instance. Valid types are:
■
Ethernet_802.2
■
Ethernet_802.3
■
Ethernet_ii
■
Ethernet_snap
link=n
Defines whether 802.3 compliant link negotiation is enabled/disabled.
■
A value of 1 (one) activates the IEEE 802.3 compliant link negotiation (default). All 3Com Gigabit EtherLink
Server NICs use link negotiation by default.
■
A value of 0 (zero) enables link signal detection. Use this setting when connecting to Ethernet equipment
that does not support link negotiation, or if there is a problem establishing a link between the NIC and the
connecting device. Unless you specify otherwise, the default signaling speed for the 1000Base-SX and 10/
100/1000Base-T NIC is 1 Gbps. When link negotiation is off, be sure that the connecting device uses the
same duplex and speed settings
duplex=n
If link negotiation has been disabled, you can select either half-duplex or full-duplex operation.
■
A value of 1 (one) enables full-duplex signaling (default).
■
A value of 0 (zero) enables half-duplex signaling.
name=
text
The name assigned to this NIC (also specified in the bind statement).
speed=
value
If link negotiation has been disabled, you can select port speed to be either 10 (Mbps), 100 (Mbps), or
1000 (Mbps).
rxflow=n
If link negotiation has been disabled, you can turn 802.3x receive flow control on or off.
■
A value of 1 (one), the default, allows the NIC to negotiate 802.3x receive flow control with the device at
the other end of the link. If 802.3x flow control is supported by the other device, receive pause packets will
be respected.
■
A value of 0 (zero) disables receive flow control.
txflow=n
If link negotiation has been disabled, you can turn 802.3x transmit flow control on or off.
■
A value of 1 (one), the default, allows the NIC to negotiate 802.3x transmit flow control with the device at
the other end of the link. If 802.3x flow control is supported by the other device, transmit pause packets
will be respected.
■
A value of 0 (zero) disables transmit flow control.
fdrfiltering=
n
This option is ignored by Model 710011and 710012 NICs. For earlier models, set this value to 1 if the NIC is
attached to a full-duplex repeater. Otherwise, set this value to 0 or leave it blank.
recvbuffers=
n
This value is the number of packet receive buffers pre-allocated by the driver for the NIC. The default value is 512.
