Commands:

mlt X enable
mlt X member x/x-x/x
mlt X encapsulation dot1q
mlt X vlan x,x,x,x,x,x,x,x,x,x,

I think should work

My money is on an issue with swith 'b":

# MLT CONFIGURATION # mlt 10 enable <----Fine mlt 1 member 3/47,3/48 vlan 1,5 <---your adding tags to MLT 1, not 10 mlt 10 encapsulation dot1q <---think there's a typo interface mlt 10 <--- yup, good perform-tagging enable <--from what I remember about 8300 OK

Looks like you've set MLT 10 to dot1q encapsulation but not mlt 1 on switch B, which is where you are adding tags to.

Hope that's all.
