CA Performance Center MIB mismatch

We have done a successful SNMPWALK to CA Performance Center, but CA does not pull the LB information we need. It pulls Generic Device Info, I don't think it realizes it is a network device. I'm on version 11.5.3 Hotfix 2 and I need pool member connections, virtual server connections etc. I'm getting nothing and heading that are useless like IBM LPAR & VMWare details.
