Default Device Groups

Default device groups serve as good examples of how selection criteria and process settings can be defined to organize your network devices, but you should learn how to create your own device groups to gain all of the benefits of the device groups feature.

The default set of device groups in NetMRI appears as a hierarchical list and includes the following:

  • Network Management: Any devices, including NetMRI appliances, that perform network management tasks.
  • Security Control: All firewall, VPN concentrator, and security management devices.
  • Network w/o SNMP: Devices that are discovered, but also discovered to lack support for SNMP protocols. This device group is required for NetMRI operation and cannot be deleted by the administrator.
  • NIOS: Device group that contains Infoblox NIOS appliances supporting the Grid Manager environment for DNS, DHCP, IPAM, and other features, if any are present in the network.
  • Routing: L3 routing devices that perform no switching or VLAN support.
  • Switch-Routers: L2/L3 switches that support routing protocols and VLANs.
  • Switches: L2 switches that do not support VLANs.
  • UNKNOWN: Includes devices that are not identified, perhaps because NetMRI does not provide device support for the devices. Newly found devices first appear in the UNKNOWN group, with SNMP collection and port scanning enabled to learn more about them. If more is learned, devices disappear from this group and appear in higher-level groups, where their process settings change accordingly. This device group is required for NetMRI operation and cannot be deleted by the administrator.
  • Network Management: All NetMRI appliances and other devices used for network management tasks.
  • Network Pending: All devices discovered and in processing by NetMRI, but not yet managed by NetMRI. This device group is required for NetMRI operation and cannot be deleted by the administrator.
  • NAME ONLY: All discovered devices for which only their name is determined by NetMRI's discovery feature based on DNS. If more is learned, such as their SNMP community, devices disappear from this group and appear in higher-level groups, where their process settings change accordingly. This device group is required for NetMRI operation and cannot be deleted by the administrator.

Default device groups can be used as-is, edited to suit your needs, or removed completely if you have admin rights to do so.

Note

Use caution when deleting default device groups. The Routing, Switching, NIOS, Optimizers, Security, and many other groups are groups built-in with NetMRI and should never be removed without first having developed new groups with the desired functionality to take their place.
