[mrtg] strange values with sub-interfaces

[Olivier Gontier]

Hello,
 
I use Mrtg 2.8.8 to monitor serial interfaces on a cisco 7507;
when I look the results, there is a big difference
between Serial6/0/0 and a sub-interface Serial6/0/0.6 .

For example:

Serial 6/0/0
 Current In : 434 kb/s

Serial 6/0/0.6
 current In : 1018 kb/s

It's not logical because In Serial values should
be the sum of In sub-interfaces values .....
