The load balacing of the VLANs is recommended best practice, however the RSM
does not have wire speed access to the backplane, it has two I/O "ports"
each one 200Mbps FDX(from memory). By default all odd VLANs are assigned to
the first port and all even VLANs to the second.  So if you have all even
VLANs supported on one switch, that RSM will only be using half of it's
throughput capability.  You can see the VLAN allocation by issuing the "show
cont c5ip" command.  After some initial queue stuff each VLAN is listed
along with the "port" it is assigned to.

To maximise the RSM capabilities you therfore have two choices

1. Split the odd and even VLANs over the two RSMs.

2. Reassign half of the VLANs in each RSM to the other I/O.

This of course is only an issue of you are likely to exceed 200Mbps
throughput.
