[mrtg] MRTG and Gigabit

[Gabriele Moroni]

Hi all,
I have a strange problem...
I generete a traffic with bwtest beetwen two windows server 2003 with gigabit port
The amount of traffic is 580 Mbit/s 
The switches beetwen the to servers are Cisco 3750 and 2960 with fiber 1gb/s connections.
The graph generated after 35 minutes is always at max 70mbit/s... maybe an error on the configuration of mrtg ?

SetEnv[aaaaaa]: MRTG_INT_IP="" MRTG_INT_DESCR="GigabitEthernet1/0/25"
