Guys,
As promised earlier, the two manpages for Crossbow are attached.
The comments/questions are the type of things that I will ask as I am
reading the man page, including the "See Also" section. I suspect
that some of the questions reflect some places where clarity could be
added and others indicate RFE's to be filed.
dladm (1M) allows creation/modification/deletion of Virtual NICs
and assigning bandwidth resources to it including binding
them to processors.
It seems as though you cannot set a limit and a guarantee. Is this
correct? For instance, if I want to guarantee 10 Mb/s but want to
set a limit of 50 Mb/s, can it be done?
If I have a physical NIC that has multiple tagged VLANs on it, can I
create a virtual NIC that is associated with one of the VLANs?
Are there any related commands that can tell you how much of a given
CPU or processor set is being consumed by a given VNIC?
Are there any related commands that can tell the administrator how
much bandwidth is being used, ideally relative to the guarantee and/or
limit? Output similar to that found by the *stat commands would be
useful. Something similar to "netrcm show-flow" may do it.
If a random mac address is chosen, are there any sort of guarantees
that it will not collide with other "random" NICs or VNICs on the
network segment?
netrcm (1M) allows assigning bandwidth and CPU resources to
flows without creating the VNICs as administrative entity (primarily
used for service consolidation and tradition QOS based usage).
If a flow is being constricted by a limit, is there any way that I can
tell that this is why my performance is bad? I'm going with the
assumption that the admin before me (who has long been forgotten) set
up a limit for a particular reason that has also long been forgotten.
I think that show-flow will do this, but an example would probably be
useful.
This is the first draft of the man pages that we are targetting for
next release of Crossbow bits. Comments/feedback welcome.
This all looks very interesting. I look forward to finding the time
to try out the goodness that crossbow brings.
