Well I wasn't very exact:

I have something like this:


ISP links ---> Freebsd Box -- gbit----- Cisco 3750 -- users.

If I issue systat -ip 1 (immediately after a reboot on the Freebsd box) I see something like:

90.000 pkt/sec forwarded ( if I look on the C3750 interface statistics I see something similar ).

If I wait 1-2-3 hours and issue systat -ip 1 I see 800-900.000 pkt/sec forwarded (but these stats don't correspond to what I'm seeing on the C3750).

If I issue systat -ip 3 then I see 90-100.000 pkt/sec which is correct.

I'm not too far off:

If you're not sure, then this is the right list.

I have a Compaq Proliant ML 350 machine with 3 x fxp and 2 x em
network cards.

If I issue :

systat -ip 1 I see:

   866056packets forwarded                0 - no checksum

the same for systat -ip 2.

For systat -ip 3 (and higher):

   83537 packets forwarded                0 - no checksum   -   these
are the correct figures


I  really don't have the figures reported for refresh-interval = 1 or
2 and have just installed Freebsd 5.4 on it. (The same problem
manifests with Freebsd 6.0 on that box).

A friend of mine has a similar setup (but not a Compaq box) and
doesn't see strange values for -ip 1 and -ip 2.



Any clue on what's happening or what's causing this ?

I'm not quite sure what you're saying here.  Are you saying that if
you use a refresh interval of 1, it tells you you're getting over
800,000 packets forwarded per second, but with a longer refresh
interval, it gives you values of around 35,000 packets per second?
And that you know from some other method that the latter is correct?
