[mrtg] MRTG and Gigabit and 10GB

I have a similar configuration with 1GB and 10GB port cards on a Unix
Do I just need to add 64 bit counters to get the correct metrics?
Also where do the Max speeds reported for the interface come from?
1GB is reporting 125.0 MB/sec
10GB is reporting 536.9MB/sec
Many thanks
John Cushnie

Tnx Paul,

it's the same to insert:
string at :::::2 (one ": " and a space and then ":::::2")
string at (only ":::::2")

You need to enable 64 bit counters.

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 ?
