Parameter Explanation
TxPriMax This parameter specifies the value of the maximum token access priority that will be allowed for
frames sent on the high-priority transmit channel. High-priority transmit frames whose Frame
Control priority value exceeds the value of this parameter will have their token access priority
reduced to the value specified by this parameter. Frame Control is a field in the IEEE 802.2
Logical Link Control (LLC) header.
Valid values: 0 to 6
The default is 6.
TxPriThresh This parameter specifies the frame priority value that will be used to transmit on the adapter’s
high-priority transmit queue. IEEE 802.2 LLC frames that contain a frame priority setting (in the
Frame Control field) that is equal to or greater than the value of this parameter are treated as
high-priority frames.
Valid values: 1 to 6
The default is 1.
LLCOnly This parameter indicates whether only LLC frames should be copied by the adapter when it is
running in promiscuous copy mode. If this parameter is set to Yes, no MAC frames will be copied
while in promiscuous copy mode.
Valid values:
Yes Copy only LLC frames.
No Copy all frames on the ring.
The default is No.
EOIDelay
(OS/2 only) This parameter should always be set to zero. It is intended for debug use.
Valid values: 0 to 10
The default is 0.
RTSWMode
(OS/2 only) This parameter indicates whether the driver should enable code that attempts to send routable
traffic directly to a destination rather than through the router. This can improve the performance of
these connections and reduce the workload at the router. If the value is Disable, all routable
frames will be sent through the router.
Valid values:
Auto Automatically determines whether to use Peer or Client mode.
Peer Communicates with a peer destination station to establish a direct path.
Client Uses an MSS server to determine the direct path.
Disable Deactivates the route switching function for this adapter.
The default is Disable.
RTSWTableSize
(OS/2 only) This parameter specifies the number of entries allowed in the route table for route switching
support. This should be set equal to or greater than the number of remote stations that this
station will send data to using routable frames (for example, TCP/IP). If it is set too low, some of
the traffic that could be sent directly will instead be sent through the router.
Valid values: 16, 32, 64, 128, 256, 512, 1024
The default is 16.
