Hi,

I have RedHat 7.0 (kernel 2.4.2) box with 3 3Com cards: 2 3Com905B Cyclone and one 3Com905
Boomerang. The problem is following: statistic gathred from Cisco-router where eth0 is connected
differs from statistic gathered from eth0. /proc/net/dev shows incomming traffic two times greather than
shows Cisco. The outgoing traffic also differs but not so much. The same situation is at eth1
connected to another Cisco-switch. The data about traffic from Cisco and Linux box is gathered using
MRTG software and I have checked that it shows same data as in /proc/net/dev.

I have installed iproute2 and netfilter, but think they shouldn't influence this problem
