> Great.  What did you change?

I had to figure out the "target" I had to gather the data from. Luckely
I allready have some knowledge for the 801, and snmpwalked both the
routers and found out what the differences and right targets where.
Here`s the target:

Target[Cisco_1]:
1.3.6.1.4.1.9.10.1.1.1.2.1.1.1.0&1.3.6.1.4.1.9.10.1.1.1.2.1.1.2.0:public
@10.0.0.1

Yes. That's right. The reason is (I think) that this network is resident
at our home, and noone was awake in the "invisible" timearea. :)

There is some local traffic involved, but the main parts of the traffic
should come from "out there".

Hm. Don't thing so. DHCP, Sendmail, POP, HTTP and the usual ports are
alle routed via the Cisco.

There it is. I`l keep on looking. Thanks..

Rougly yes. But there is some noticable differences.

No. What I cant seem to find out is if it`s k/s *or* kb/s that's the
right numbers for the FreeBSD og for the Cisco. When the traffic
increases on the Cisco, it also increases on the FreeBSD (and vicevera).
There`s only the matter off which of the graphs shows the "right"
prefix.

Thanks..
