FORCEDUPLEX
Duplex modes
Auto-negotiate: The adapter negotiates with the hub how to send/receive packets, either full- or half-duplex. If it is unsuccessful at negotiating the duplex, the adapter defaults to half-duplex. You must have an auto-negotiating hub (an Nway* switch) to get full-duplex support with the FORCEDUPLEX parameter set to 0 (auto-negotiation).
Full-duplex: The adapter sends and receives packets at the same time. This improves the performance of your adapter. Set duplex mode to full-duplex ONLY if you have a switch that supports full-duplex.
Half-duplex: The adapter performs one operation at a time. It either sends or receives.
| Note |
The PRO/100B T4 adapter does not support full-duplex at 100 Mbps, nor does the T4 adapter support Auto-Negotiation, or Nway. The EtherExpress™ PRO/100+ TX adapter does not have any of these limitations. | |
Syntax: FORCEDUPLEX=n
Where n=0 auto-negotiate (EtherExpress™ PRO/100+ TX adapter only)
1 half-duplex
2 full-duplex
| Note |
If the adapter is set to half- or full-duplex, set the SPEED parameter to either 10 or 100 (see SPEED below). | |
Default: auto-negotiation (PRO/100+ TX adapter)
half-duplex (PRO/100B T4 adapter)
Examples:
PRO/100+ TX adapter (100 Mbps full-duplex):
FORCEDUPLEX=2 SPEED=100
EtherExpress PRO/100+ TX adapter (10 Mbps full-duplex):
FORCEDUPLEX=2 SPEED=10
PRO/100B T4 adapter (100 Mbps full-duplex):
Not Supported
PRO/100B T4 adapter (10 Mbps full-duplex):
FORCEDUPLEX=2 SPEED=10
SLOT (required)
For PCI adapters, SLOT is derived from bus number and device location as defined by the PCI specification. One way to determine the slot number is to load the driver from the command line. You will be prompted with valid device number(s) for the adapter(s). Select one of them.
Syntax: SLOT=n (n = 1,2,3,4,...)
SPEED
Specifies the speed the driver uses. If you don't use this parameter, the driver automatically detects the network speed. If it is unable to autosense, the driver defaults to 10 Mbps.
| Note |
You must set the SPEED parameter to either 10 or 100 if you're setting the FORCEDUPLEX parameter to either half- or full-duplex. | |
If you use this parameter, the driver operates at the specified speed instead of auto-detecting network speed.
Syntax: SPEED=n (n = 10 or 100)
Default: The adapter automatically senses speed
NODE
Specifies a local administered address (LAA) unique to each adapter. Use this option to provide your own unique node address for the adapter. The node address is a 12-digit hexadecimal number; the second digit must be one of the following digits: 2, 6, A, E.
Syntax: NODE=xnxxxxxxxxxx
n = 2, 6, A, E
x = hexadecimal number
Default: The adapters assigned address
FRAME
Indicates one of four valid frame types the system is transmitting and receiving.
Syntax: FRAME=n
| n= |
Ethernet_802.2
Ethernet_802.3
Ethernet_II
Ethernet_SNAP | |
Default: Ethernet_802.2
TXTHRESHOLD
Represents the threshold for transmits from extender SRAM FIFO (output buffer).
Syntax: TXTHRESHOLD=n (n = number of 8 bytes)
For example, 16 represents 16x8 (or 128 bytes). In this case, the LAN controller transmits after copying 128 bytes from the host memory.
Default: dynamically set
The maximum number that you can specify is 200 (200x8=1600 bytes), which ensures there will not be any under runs.
