Both tools can create an inventory, but they work best in tandem. If both are installed, the best practice is to have NNMi discover initially and pass the information over to NA. In this post I’ll cover the functionality of NNMi, in my next post I’ll cover how NA works.
NNMi first discovers your network. You “seed” the discover by giving it the IP address of a well-connected node and it takes over the process from there by looking at connections, routing tables, etc. It populates its database with:
Layer 2 Connections
Chassis Redundancy Groups
Card Redundancy Groups
Router Redundancy Groups
Router Redundancy Members
You access this information in the Inventory workspace. There are some important differences between inventory workspace views that you need to know:
The (All Attributes) table views Nodes (All Attributes), Interfaces (All Attributes), and IP Addresses (All Attributes)) shows all columns (attributes) available for the object type. Configure these views to meet your current need.
The other table views display a pre-determined subset of columns (attributes).
These views can be sorted or filtered by any column (for example by vendor).
When you select an object, the Analysis Pane displays in the bottom half of the window .The Analysis Pane's Details tab includes a System Description attribute with the IOS version for any Cisco device. Each tab in the Analysis Pane provides you with more details.
