I've seen this as well - you'll also find that when you reboot the 
router the OIDs will revert back to some other number so you'll have 
to redo MRTG again. I haven't found any other static OIDs to use.

What I think is happening is that the QoS config gets allocated an 
OID every time you change it - pretty much the next available OID 
that hasn't been used. But on a reboot, the QoS OID table is clean so 
the first "n" OIDs are allocated. If your QoS config is static (which 
it sounds like it isn't for you) then a reboot will give you the 
permanent numbers.

Hope this makes sense...
