# NetWare* Command Line Parameters and Keywords

## CE1000 (Server Driver)

The following NetWare Keywords are applicable for the CE1000 driver.

To view the keywords for Advanced Network Services (ANS), such as VLANs, please click here.

Parameter | Values | Default Value | Description
--- | --- | --- | ---
Slot | 1-valid slot# | None | This is a standard keyword parameter predefined by NetWare to specify the physical slot of the installed adapter. When multiple adapters reside in a system, the SLOT keyword is used to distinguish which physical adapter is being loaded. If multiple adapters do exist in a system and the command line does not contain the SLOT keyword, the system will build a list of adapter slots and prompt the user to select an adapter to be loaded.
Frametype | ethernet_802.2 ethernet_802.3 ethernet_snap ethernet_ii | ethernet_802.2 | Configures the adapter to process the valid NetWare Ethernet frame types.
Speed | 0, 10, 100 | 0 | On copper-based adapters, forces the line speed to the specified value in Mbps. If this parameter is not specified, or is set to 0, the adapter will auto-negotiate to the best possible link based on link partner. Gig speed can only be achieved by auto-negotiation. This setting has no effect on fiber adapters which are defined to be 1000 Mbps.
Forceduplex | 0 – 2 | 0 | On copper-based adapters, forces the duplex mode. 1 indicates half duplex, 2 indicates full duplex. If this parameter is not specified, or is set to 0, the adapter will auto-negotiate to the best possible link. If it cannot auto-negotiate, it will default to half-duplex. This setting has no effect on fiber adapters which are defined to be full duplex.
Autoneg | 0 - 255 | 0 | Controls auto-negotiation on copper-based adapters. When this parameter is used, the Speed and Forceduplex parameters must NOT be specified. Please see the manual for values. This setting has no effect on fiber adapters which are defined to not negotiate speed or duplex to any value but 1000 Mbps, full duplex.
FlowControl | 0 - 3 | 3 | Controls the ability of the adapter to advertise flow control capabilities. Default is to allow both TX and RX flow control. 0 is off, 1 is RX, 2 is TX, 3 is both.
Jumbo | 0-16380 | 0 | Enables jumbo frames and sets the maximum frame size. Setting this parameter to 0 disables jumbo frames and causes the adapter to use standard 1514 bytes frames. This feature is available in NetWare 6.0
XsumTX | 0-1 | 0 | When set to ‘1' the driver and hardware can “offload” the calculation of the TCP or UDP checksum values for transmitted TCP or UDP packets, when the stack supports such operation. When set to ‘0' the checksum is calculated normally by the TCP/UDP protocol layers. Non TCP/UDP packets (such as IPX) are not affected by this parameter. This option only works on supported OS versions. Unlike other keywords, this setting is tracked on a per-frame-type basis, and only works on Ethernet II and Ethernet SNAP frame types.
XsumRX | 0-1 | 0 | When set to ‘1' the driver and hardware can “offload” the calculation of the TCP or UDP checksum values for received TCP or UDP packets, when the stack supports such operation. When set to ‘0' the checksum is calculated normally by the TCP/UDP protocol layers. Non TCP/UDP packets (such as IPX) are not affected by this parameter. This option only works on supported OS versions. Unlike other keywords, this setting is tracked on a per-frame-type basis, and only works on Ethernet II and Ethernet SNAP frame types.
WaitForLink | 0 -1 | 1 | Controls whether or not the driver will wait for link before finishing initialization. The default value causes the driver to wait until auto-negotiation is complete before finishing initialization and returning to the command prompt. Setting this value to 0 may cause the driver to initialize faster, but also may cause it to display incorrect link information when it loads.
Poll | 0 - 2 | 0 | Controls whether or not the driver loads in polling mode.0 means no polling (e.g. interrupt mode), 1 means polling is forced on, and 2 means auto-detect. In this case, the driver will query the OS to determine whether or not polling is supported and will enable polling support accordingly. If supported by the OS, polling can decrease CPU usage by the driver when under heavy network load.
Persist | 0 - 2 | 2 | Controls whether the driver remains persistent during a hot-plug event. Setting this parameter to 0 disables persistency; the driver will always unload during hot-plug. Setting this parameter to 1 forces the driver to remain persistent during hot-plug events. The default value, 2, sets the driver in auto-persistency mode. In this mode, the driver will only remain persistent when it is used with iANS (teaming/VLANs)
TxDescriptors | 8-65535 | 96 | TX descriptors are used to tell the hardware where the fragments of a transmit packet are in host memory. A transmit packet can use 1 or more descriptors. Most transmits require 3 or 4 descriptors. Each descriptor is 16 bytes.
RxDescriptors | 8-65535 | 64 | RX descriptors tell the hardware where to DMA received packets. For each RX descriptor the driver will also allocate a receive buffer. Each descriptor is 16 bytes and each buffer is 2048 bytes.
CoalesceBuffers | 1-65535 | 96 | Coalesce Buffers are used to copy fragments of a transmit packet into before assigning them a transmit descriptor. This reduces the number of transmit descriptors required for each packet transmission. Each Coalesce buffer is 2048 bytes.
The following keywords apply only to 82544-based adapters and should be used when there is a high RX Missed packets Count.
Highwm | 0x8008 only | not included | Sets the high watermark for flow control packets.
Lowwm | 0x8008 only | not included | Sets the low watermark for flow control packets.
Pausetime | 0x2000 only | not included | Sets the pause time between flow control pause frames.

## E1000ODI (Gigabit ODI client for DOS)

The following NetWare Keywords are applicable for the E1000ODI driver.

Parameter | Values | Default Value | Description
--- | --- | --- | ---
SpeedDuplex | 0 - 3 | auto-detected during initialization | 0=Force speed to 10Mb and duplex to half. 1=Force speed to 10Mb and duplex to full. 2=Force speed to 100Mb and duplex to half. 3=Force speed to 100Mb and duplex to full. >3=ignored + error message displayed. Auto-detection by the controller is disabled and the speed and duplex modes are set as specified. The controller will not be able to auto-detect the mode until the driver is reloaded. If the SpeedDuplex mode does not match the actual mode of the port in use, the driver may or may not function for certain levels of traffic, and then begin to lose frames. The SpeedDuplex parameter is valid for copper-based controllers and will be ignored when used on a fiber-based adapter. Gigabit copper adapters currently cannot be forced to 1000 Mb due to limitations in the IEEE specification.
Slot | 0 - FFFFh | auto-configure if possible | The driver uses the value of the parameter to determine which adapter to control If the value does not correctly indicate a valid slot number or the adapter is already in use, an error message is displayed and the driver treats this as a fatal error.
