Using Device Drivers
For complete communication with devices, the OpenManage Network Manager (OMNM)
application requires a device driver. For example, to communicate with Dell EMC devices, you
must have a Dell EMC driver installed. That does not mean you cannot discover and communicate
with other vendors’ devices without a driver installed. See
.ocp and .ddp files on page 104 for driver
installation instructions. The following sections include discussions of some of these drivers:
•
Base Driver
• Supported PowerConnect Models
• Windows Management Instrumentation (WMI) Driver
• Web-Based Enterprise Management (WBEM) Driver
Base Driver
If you have no driver installed, the OpenManage Network Manager (OMNM) application provides
the following functionality, depending on the devices’ supporting and providing data from the
SNMP system group (sysDescr, sysObjectID, sysUpTime, sysContact, sysName, sysLocation) and
the ifTable, which provides list of device interface entries from the RFC1213-MIB. The OMNM
application also depends on the entPhysicalTable in the ENTITY-MIB, which provides a list of
physical entities contained on a device. If the device does not support the ENTITY-MIB, then the
OMNM application bases sub-component creation entirely on ifTable contents.
Confirm that a device is not part of those supported by installed drivers when part of its OID is
3477.
Functionality Description
Top Level Resource The OMNM application creates top level resource for discovered devices with the
following attributes: Equipment Name, Description, IP Address, Location, Contact,
Vendor, Model, System Object Id, Date created, Creator, Discovery date, Last
Modified.
Subcomponents The OMNM application creates subcomponents (modules, ports, interfaces, power
supplies, fans, and so on) for discovered device based on contents of
entPhysicalTable.
Port/Interface
Attributes
The OMNM application sets Port/Interface Attributes depending on port/interface
type: Name, Port Description, MAC Address, Administrative State, Operational
State, Port Type, Speed, Encapsulation, Operation Type, Switch Mode, CLI Name, If
Index, Port Number, and Slot Number.
Direct Access SNMP and Ping (ICMP) are enabled.
Monitors The OMNM application automatically adds discovered device instances to the
Default ICMP Monitor to indicate their Network Status. Support for SNMP based
performance monitors using discovered ports and interfaces as targets is also
possible. For example, Bandwidth Utilization.
Reports You can execute reports like the Port Inventory Report or Device Inventory and
results should include discovered device and device port entities.
Network View Discovered devices and their sub-components appear, regardless of whether a device
driver exists for them.
Events The OMNM application supports standard MIB-II traps for discovered device and or
sub-components. For example, linkUp, linkDown, coldStart, warmStart, and so on.
