Parameter Options

Description

Slot = n

Identifies the slot number for the specific
adapter currently being configured. This

parameter is not necessary if only a single
adapter is installed.

Speed = n

If link negotiation has been disabled, specifies
port speed to be either Auto, 10HD or 10FD,

100HD or 100FD.

Jumbo =

Set maximum physical receive
packet Size = 18000 in the

STARTUP.NCF. Choices are

Jumbo = 1514–9000. This
keyword is only supported on

NetWare 6.x.

Enables/disables Jumbo Frame support. When
enabled, jumbo packets of up to 9000 bytes

are supported. Not supported on NC1020

adapters.

Link= Default=FORCE

Selections are: AUTO, FORCE

Only used to allow the adapter to negotiate a
specific or forced line speed with a switch that

is not forced, but instead setup for auto-

negotiation. It is best to allow for auto-
negotiation of the card and switch by not

setting this keyword or the speed keyword.

Only use this keyword if the speed keyword is
set to something other than AUTO.

RxTicks=

Default = 360
Min = 0, disabled
Max = 5000000, 5 seconds
Units are in micro seconds

Enables the use of batching receives within a

specific time period.

TXPacketsPer

Default = 64
Min = 0, disabled
Max = 100

Enables the use of batching transmits to a
specific amount of packets.

NOTE:

With Jumbo Frames, the first frame must be Ethernet_ii.

Post installation
After NetWare 6.x has been successfully installed, set the minimum packet receive buffers parameter in
the startup.ncf file to 1500 for each adapter in the system. Set the maximum packet receive buffers to

three times the minimum packet receive buffers. Typically one MB of RAM is required per 1000 receive

buffers.
In the autoexec.ncf file, delete the packet receive buffers parameter (RxBuffers=32) in the load

statement for this adapter. Deleting the receive buffers phrase from the load statement resets the receive

buffers parameter to the default value of 200 for this adapter. You must reboot the server for the new

configuration.
Example:
The default maximum number of receive buffers for the system is 500; the default minimum is 128. Edit

the startup.ncf file to have the following entries. The actual numbers will be a function of the number of

adapters in the system.

set maximum packet receive buffers = 30000
