Configure Device Profiles

You can modify the settings in the Device Profiles to fine-tune Spiral Discovery and the device symbols on the maps.

According to industry standards (RFC 1213, MIB-II), each combination of vendor, device type, and model number is assigned a unique SNMP system object ID (sysObjectID). For example, all Cisco 6500 series switches have the same sysObjectID prefix: .*

provides well over three thousand preconfigured Device Profiles, one for each known sysObjectID at the time NNMi released.

NNMi uses Device Profiles (which equate to sysObjectID) to control certain types of behavior:

  • Spiral Discovery determines the closest matching device profile, and uses the device profile settings to control certain attribute values for the discovered device. The Device Profile also influences the following:

    • Auto-Discovery Rules can provide an sysObjectID list that expandsthe default discovery behavior (beyond routers and switches) or prevents troublesome device types from being discovered.
    • The Node Name value might be affected, depending on your choices, see "Configure the Node Name Strategy".
  • When Node Groups are defined based on system object IDs, the State Poller Service monitors devices based on attribute values in the device profiles.
  • Device Profile settings influence how State Poller detects renumbered interfaces.
  • In Map views, the background shape of map icons is determined by the Device Category. There is also a Force Device attribute that enables category overrides in troublesome situations.

Tip To quickly locate the device profile settings for a particular network device, sort or filter the Device Profiles view by clicking the heading for the Device Vendor, Device Model, or Device Category columns.

To access the device profile definition for a particular device type:

  1. Do one of the following:

    • To create a device profile, click the  New icon.
    • To edit a device profile, click the  Open icon in the row representing the configuration you want to edit.
  2. Modify the settings as needed:

    • The basic settings modify NNMi behavior for Spiral Discovery and map symbols.

      Caution If you make changes to a Menu Item provided by NNMi, those changes are at risk of being overwritten in the future. See Author form for important information.

    • The advanced settings control NNMi behavior for Spiral Discovery and Node name selection. For example, instruct NNMi to treat a certain device type as a Router.

    When you make a change, NNMi must update all references to device profiles. This can take some time and slow down your system. Consider making this change during a slow time in your network environment.

  3. Click  Save and Close. NNMi applies your changes during the next regularly scheduled discovery cycle. To apply the changes immediately, use ActionsPollingConfiguration Poll. See Using Actions to Perform Tasks for more information.
You can also right-click any object in a table or map view to access the items available within the Actions menu.
