It is some time ago and my memory may be a bit fuzzy, but if memory serves
me well, the problem you describe last is that the switch offloads traffic
to the backbone so it is never seen by the vlan interfaces, only the
initial frame.

And for the first problem: you will not find this in MRTG documentation as
this is not an MRTG problem. You will need to look through Cisco
documentation and/or experiment with SNMP walk to find what you are
looking for. If available at all.

Maybe you can call Cisco or whoever sold you the switch?
