In looking at the flowadm.1m manual page (from npt.sfbay) we see:
FLOW PROPERTIES
The following flow properties are supported. Note that
the ability to set a given property to a given value depends
on the driver and hardware.
maxbw Sets the full duplex bandwidth for the link. The
bandwidth is specified as an integer with one of the
scale suffixes(K, M, or G for Kbps, Mbps, and Gbps).
priority
Sets the relative priority for the link. The value may
be given as one of the tokens rt(real time), high,
normal,
or low.
cpus Bind the processing of packets for a given flow to
a processor or a set of processors. The value can be
a comma separated list of one or more processor id.
If the list consists of more than one processor,
the processing will spread out to all the processors
although connection to processor affinity and packet
ordering for packets of any individual connection will
be maintained.
The processor or set of processors are not exclusively
reserved for the network device. Only the kernel
threads and interrupt associated with processing of
the device are bound to the processor or the set of
processor specified. In case, it is desired that
processors be dedicated to the device, psrset(1M) can
be used to create a processor_set and then
specifiying the processors from the processor_set to
bind the device to.
If the link was already bound to processor or set
of processors due to a previous operation, the binding
will be removed and the new set of processors will be
used instead.
Shouldn''t the word ''link'' be replaced with
''flow'' in most (all?)
cases?
I''m only really interested in setting properties on flows that
represent a whole link (there''s no need to partition the traffic). The
flowadm syntax appears to require that I provide some attributes. Is
that correct?

You don''t want to assign the property to the link itself? -venu> > dme. > -- > David Edmondson, Sun Microsystems, http://dme.org > _______________________________________________ > crossbow-discuss mailing list > crossbow-discuss at opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/crossbow-discuss >
