Brocade XMR/MLX VLAN bit counters (Cacti graphs for brocade VLANS) (95% billing).

Sneaky hack: Slap an in+out rate limit on the vlan with high settings 
(i.e. same as port/lag speed) and just graph the OID of the rate limit 
counter :-)
Might need to take a multiplier calculation/CDEF into account based on 
the number of ports you have in the lag.

The new 8x10 cards have built in ve counters indeed which makes it a lot
