Determine switch buffer size
Hi everybody,

I need to calculate the tcp buffer size of a network switch, since it's not specified in the manual; how do I do this?

I have some machines connected to the switch and I can run some socket tests written in C between these machines (I can choose how many bytes to send and calculate the senders' and receiver's bandwidth) and I guess I need to keep sending more and more data until I see some slowdown in the sender's bandwidth (because that means that the senders are sending more data than the switch can handle), but I'm not sure about this.

Thanks for your help!

scconf_transp_adap_sci(1M)				  System Administration Commands				scconf_transp_adap_sci(1M)

NAME

       scconf_transp_adap_sci - configure the sci cluster transport adapter

DESCRIPTION

       Note -

	 Beginning  with  the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
	 still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more  infor-
	 mation about the object-oriented command set, see the Intro(1CL) man page.

       You can configure sci SCI-PCI adapters as cluster transport adapters. These adapters can be used with the dlpi transport type.

       The adapter name is sciN, for example, sci0. Do not use scidN as the adapter name.

       An  sci	adapter can only be connected to another sci adapter or to an SCI switch. When an sci adapter is connected to an SCI switch, it is
       important that you specify the correct port name when referring to a port on the switch as an endpoint argument to the scconf or  scinstall
       utility.  The port name must match the port number on the SCI switch (the number that is printed on the switch itself). Failure to give the
       correct port name could result in the operation failing. The result of providing an incorrect port name will be the same as you	would  see
       if the cable between the adapter and the switch were removed.

       There are no user-configurable properties for cluster transport adapters of this type.
