This chapter contains the following topics:

Viewing Inventory Information

Beginning with Cisco Prime DCNM release 6.x, you can view the inventory and the performance for both SAN and LAN switches by using the global Scope pane. You can select LAN, SAN, or both to view the inventory information. You can also export and print the inventory information.

You can either Print this information or export to Microsoft Excel.


Note
You can use the Print icon to print the information that is displayed or you can also use the Export icon to export the information that is displayed to a Microsoft Excel spreadsheet. You can also choose the column that you want to display.

The Inventory menu includes the following submenus:

Viewing Inventory Information for Switches

To view the inventory information for switches from the Cisco DCNM Web UI, perform the following steps:

Procedure

Step 1

Choose Inventory > View > Switches.

The Switches window with a list of all the switches for a selected Scope is displayed.

Step 2

You can also view the following information.

  • Group column displays the switch group to which the switch belongs.

  • In the Device Name column, select a switch to display the Switch Dashboard.

  • IP Address column displays the IP address of the switch.

  • WWN/Chassis ID displays the Worldwide Name (WWN) if available or chassis ID.

  • Health displays the health situation of the switch.

    Note 

    To refresh and recalculate the latest health data for all the switches on Cisco DCNM, click the Recalculate Health button above the switches table.

  • Status column displays the status of the switch.

  • # Ports column displays the number of ports.

  • 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.

  • License column displays the DCNM license that is installed on the switch.

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

Step 3

In the Health column, the switch health is calculated by the capacity manager based on the following formula in the server.properties file.

The function to implement is:

# calculate(x, x1, y, y1, z).

# @param x: Total number of modules.

# @param x1: Total number of modules in warning.

# @param y: Total number of switch ports.

# @param y1: Total number of switch ports in warning.

# @param z: Total number of events with severity of warning or above.

Step 4

The value in the Health column is calculated based on the following default equation.

((x-x1)*1.0/x) *0.4 + ((y-y1)*1.0/y)*0.3 + ((z*1.0/1000>=1) ? 0: ((1000-z)*1.0/1000)*0.3).

In the above formula, the switch health value is calculated based on the following:

  • Percentage of Warning Modules (Contributes 40% of the total health).

  • Percentage of Warning Ports (Contributes 30% of the total health).

  • Percentage of events with severity of Warning or above (Contributes 30% of the total health. If there are more than 1000 warning events, the event health value is 0).

You may also have your own health calculation formula by implementing the common interface class: com.cisco.dcbu.sm.common.rif.HealthCalculatorRif. Add the .jar file to the DCNM server and modify the health.calculator property to point to the class name you have created.

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

  • 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.
