have I activate flow control on all ports of switch?I have 8
machine with intel core2quad cpus my switch is HP procurve 2824
can you lead me to some documenations for true configuration of
switch for Gromacs cluster
Thank You
Find out the IP address of the switch, then telnet there. You will see
some prompt
like
ProCurve Switch 2848#
then type <menu>. Under item 2) subitem 2) you will find the port/
trunk settings. There is
a column "Flow Ctrl" on the right hand side for each port which you can
toggle from "Disable" to "Enable" with the space bar. More information
will
be available in the manual, see e.g.
http://www.hp.com/rnd/support/manuals/2800.htm

Dear Ha Salem,
in all the switches we tested at that time, flow control
was disabled by default. You can
connect to the switch (e.g. via telnet) and activate flow
control. For the ProCurve switches
flow control can be enabled and disabled for each of the
ports individually.
