Hi, I am the OpenView guy at Hewlett-Packard that developes the integration with Cisco products such as CiscoWorks and Cisco WAN Manager.
I would like to make available the interactive site that I maintain that describes this really cool integration. Check out http://neutron.external.hp.com for more details. I just created a new step-by-step demo with NNM->CiscoWorks VLAN/ATM solution that you see actual screenshots of this integration solution.
We also have a Smart Service Management Solution for Cisco Environments (manage Cisco Networks as a service) at http://neutron.external.hp.com/cisco-main.htm .
We are coming out with a new add-on for Network Node Manager this year called NNMET (Network Node Manager Extended Topology), this add-on allows NNM to manage layer-2 and layer-3 connectivity....stay tuned
