Hello,
I'm new to the list and maybe someone has some experience with this and
could
give
me some advice. I sent this questions to the Misc list, but I didn't received
any reply yet. I
hope that someone here may help me.
I would like to know what kind of information would SFlow give me from
a chain-
linked switch that does NOT support SFlow. The network would be something like
this (sorry,
I'm too bad drawing with letters!):
Gateway
|
Procurve 2800
| |
Non-sflow switchA Non-slow switchB
| |
Network devices Network devices
For some systems (printers, voip phones, some departments...) I do not
need the
performance of one Procurve's Gb port, so I would use those ports for other
systems and use
a different switch to give network access to less performance-hungry devices.
It's basically a
matter of cost per port, trying to avoid buying 2 or more ProCurve and reuse
some basic
switches that I have right now.
- Would I see real information for traffic that comes from / goes to
systems
connected
to the Non-sflow switches? Obviously all traffic would be detected on the
Procurve port that
has switchA and switchB connected to, but I suppose that I should get the IP
address of each
system and be able of identify each one through it (as is there was just one
system with many
IP addresses).
- Would I be able of getting real traffic stats from those systems?
- Would all this work if the switches are connected with a 2Gb trunk?
Many thanks in advance,
Victor.
