It depends. Are the models similar enough to share most of the vendor 
specific code or are they so different (eg completely different 
operating system or acquired / OEM'ed from different companies) that 
each model or group of models should be put in a separate device class?

For example: depending on the model, an HP switch is classified as 
SNMP::Info::Layer2::HP4000 (old ProCurve models with only menu driven 
interface), SNMP::Info::Layer2::HP (more current ProCurve models that 
also have a CLI and differ in SNMP support), SNMP::Info::Layer2::HPVC 
for VirtualConnect interconnects in blade chassis and 
SNMP::Info::Layer3::H3C for HP switches running Comware operating system.

Without any information about the (dis)similarities between the 
platforms and without seeing the MIB contents it's hard to advise or 
assist you.

Can you provide a bit more background / info on the various models and 
can you upload the MIBs that you'd need in a Sourceforge ticket for 
netdisco-mibs ?
