Table 9. DOS and OS/2 NDIS device driver parameters in PROTOCOL.INI (continued)

Parameter

Explanation

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

This parameter specifies the number of entries allowed in the route table for route switching

only)

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.

 

 

RTSWSubnetMask (OS/2

This parameter contains a character string specifying the IP Subnet Mask for the IP subnet

only)

to which this adapter will attach. This value is entered as an IP dotted decimal value, for

 

example, 255.255.255.0. This is a mandatory parameter when the RTSWMode parameter is

 

set to Auto or Peer.

 

Valid values:

 

xxx.xxx.xxx.xxx

 

 

A dotted-decimal IP network number (15 characters maximum).

 

Disable

 

 

 

When not in use.

 

The default is Disable.

 

 

RTSWHoldingTime (OS/2

This parameter specifies the Route Switching information holding time value. This

only)

determines how often a remote station must refresh its Route Switching information which

pertains to this station. Valid values: 2 to 20 The default is 20.
