MacIPX control panel A-7
Use the information in the following tables to set parameters for:
1 MacIPX
1 SPX (Sequenced Packet Exchange)
1 SAP (Service Advertising Protocol)
1 RIP (Routing Information Protocol)
For the following SPX parameters, you can enter any value between 0
and 9999. The values for Abort Timeout, Listen Timeout, and Verify Timeout
apply only to those SPX connections using the “watchdog,” such as
those used by FileMaker Pro 4.0.
MacIPX parameter Function
Disable IPX
Diagnostic Services
Disables the IPX Diagnostic Services, used by some network
management tools. Disabling IPX Diagnostic Services can
reduce the amount of memory that MacIPX uses. Click this
parameter if you don’t use any network management tools, or if
your tool doesn’t use IPX Diagnostic Services.
Maximum Network
Packet Size
Limits the maximum network packet size. The value can’t be
greater than the maximum value supported by the physical
network. Enter 0 (zero) to let MacIPX determine for itself what
value to use.
Enable IPX
Checksumming
Enables checksumming of IPX packets. The option is
unavailable if the current network doesn’t support IPX
checksumming.
SPX parameter Function
Abort Timeout Sets the amount of time that SPX waits, without receiving any
response from the other side of the connection, before it
terminates the session. The timeout number is expressed in ticks
(with 60 ticks per second). The default value is 2400 ticks, or 40
seconds.
Listen Timeout Sets the time that SPX waits (without receiving a packet from the
other side of the connection) before it requests the other side to
send back a packet assuring that the connection is still valid. If
SPX hasn’t heard from the other side of the connection within this
time, it sends packets to the other side asking for verification that
the connection still exists. The default value is 1200 ticks, or 20
seconds.
Verify Timeout Sets the frequency at which SPX sends a packet to the other side
of a connection to inform it that its side is still active. If no
packets are being exchanged on the SPX connection by the
software that established the session, SPX sends packets at
regular intervals to make sure that the connection is still working.
The default value is 480 ticks, or 8 seconds.
