  • Model column displays the model name of the switch.

  • Serial No. column displays the serial number of the switch.

  • Release column displays the switch version.

  • Up Time column displays the time period for which the switch is active.

Step 3

Click Health to access the Health score window for a device. The Health score window includes health score calculation and health trend. The Overview tab displays the overall health score. All the modules, switch ports and alarms are taken into consideration while calculating the health score. Hover over the graph under Health Trend for detailed information on specific dates. Hover over the info icon next to Alarms to display the number of Critical, Major, Minor, and Warning alarms that have been generated.

Click the Modules tab to display information about the various modules in the device. This tab displays information such as Name, Model name, Serial number, Status, Type, Slot, Hardware revision and Software revision.

Click the Switch Ports tab to display information about the device ports. This tab displays information such as Name, Description, Status, Speed, and the device to which a port is connected .

Click the Alarms tab to display information about the alarms that have been generated. This tab displays information such as alarm Severity, Message, Category, and the Policy that has been activated due to which the alarm is generated.

In the Health column, the switch health is calculated by the capacity manager based on the following parameters:

  • Total number of modules

  • Total number of modules impacted by the warning

  • Total number of switch ports

  • Total number of switch ports impacted by the warning

  • Total number of critical severity alarms

  • Total number of warning severity alarms

  • Total number of major severity alarms

  • Total number of minor severity alarms
Step 4

The value in the Health column is calculated based on the following:

  • Percentage of modules impacted by warnings (Contributes 20% of the total health).

  • Percentage of ports impacted by warnings (Contributes 20% of the total health).

  • Percentage of alarms (Contributes 60% of the total health). The critical alarms contribute the highest value to this percentage followed by major alarms, minor alarms and warning alarms.

You may also have your own health calculation formula by implementing the common interface class: com.cisco.dcbu.sm.common.rif.HealthCalculatorRif.

The default Java class is defined as: health.calculator=com.cisco.dcbu.sm.common.util.HealthCalculatorAlarms.

  • Capacity Manager calculates health only for the license switches. If the health column does not display a value, the switch either does not have a license or it has missed the capacity manager daily cycle.

  • If the switch is unlicensed, click Unlicensed in the DCNM License column. The Administration > License window appears which allows you to assign a license to the user.

  • The capacity manager runs two hours after the DCNM server starts. So, if you discover a device after two hours of the DCNM start time, the health will be calculated 24 hours after this DCNM start time

FEX

The Fabric Extender feature allows you to manage a Cisco Nexus 2000 Series Fabric Extender and its association with the Cisco NX-OS switch that it is attached to. A Fabric Extender is connected to the switch through physical Ethernet interfaces or a Port Channel. By default, the switch does not allow the attached Fabric Extender to connect until it has been assigned a chassis ID and is associated with the connected interface. You can configure a Fabric Extender host interface port as a routed or Layer 3 port. However, no routing protocols can be tied to this routed interface.


Note
FEX feature is available on LAN devices only. Therefore, you will see FEX on Cisco DCNM Inventory Switches. FEX is also not supported on Cisco Nexus 1000V devices.

Note

4x10G breakout for FEX connectivity is not supported on Cisco Nexus 9500 Switches.


Note

The Fabric Extender may connect to the switch through several separate physical Ethernet interfaces or at most one port channel interface.

Discovery

Starting from Cisco DCNM release 10.x, Cisco DCNM Web Client allows the admin to associate user to one or more device scope or group. That means you can only access and configure the associated group or scope devices based on Role Based Access Control (RBAC). Though you might not have the access to other users' associated devices, you can still see all the discovered devices under the Inventory > Discovery tab.

From the left menu bar, go to Administration > Management Users. You can create users and associate groups, manage remote authentication, and see all the connected clients. For more information about RBAC, navigate to Management Users.
