How the MAC <-> port bindings are retrieved by macsuck depends more on
the version of SNMP::Info than on the version of Netdisco you're using.
As far as I can see, the Catalyst 4500 is in the same class as the
Catalyst 4000 switch. 

The code suggests they both use Cisco community-based indexing (ie
"community@vlan"). I don't have access to a 4500 to verify, perhaps
someone else on the list can share their experience with Cat4k in
Netdisco?

Of course it never hurts to upgrade to the most recent versions of
Netdisco and SNMP::Info...
