[mrtg] Cisco 4500: No sub interface data in CFG file.

Our two Cisco 4500 routers connect to approx 50 Area Office sites using
Frame Relay. I can successfully run cfgmaker against router 1 .The resulting
cfg files show all serial sub-interfaces.

When cfgmaker is run against router 2 (using the same Community sting, and
options) the cfg file shows the physical serial interfaces but no
sub-interface information. 

These routers are managed by our carrier so we have no "official" access.
However I got the current configs on both routers and have compared the two.
I can see the following differences:

IOS versions:

Router1 = 11.2
Router 2 = 11.0

Serial Interface differences:

Router1 = all Sub interfaces configured as S1.<sub interface no>
Router2 = all Sub interfaces configured as S0.<sub interface no>

Finally there are some access-list differences which I don't believe bare
relevance but can be provided if required. 

The SNMP community strings and other SNMP-related lines are identical.

Are the above differences important? If not does any-one have any ideas?
