Configuring and Monitoring the Nexus Virtual Switch as a Managed Device
A managed device is a switch from which you would like to gather information such as interface statistics. For Nexus virtual networks, virtual interfaces statistics will provide insight into your virtual network.
This chapter contains the following sections:
•Setting Up the Managed Device Parameters
•Monitoring the Managed Device Interfaces
Setting Up the Managed Device Parameters
When you set up a managed device, the NAM retrieves interface information via SNMP from that managed device and displays statistics. For NAM on Nexus VSB, you should set these parameters to point to a Nexus 1000v switch.
Step 1 In the Content menu, click Setup > Managed Device Parameters.
Step 2 The window will display the dialog box for configuring a managed device, as shown in Figure 5-1.

Step 3 Enter the IP address of the Nexus virtual switch you would like to monitor. You must enter the SNMP Read-Write Community String for that switch in both fields.
Step 4 Click the Test Connectivity button. On the window that appears, make sure that "SNMP Read from Managed Device" and "SNMP Write from Managed Device" both say OK.
Step 5 Click Close.
Monitoring the Managed Device Interfaces
Monitoring the managed device interfaces provides per-interface statistics directly from the Nexus switch.
Go to the Monitor tab and then select Managed device (see Figure 5-2). You will see three radio buttons: "Current Rates," "TopN Chart," and "Cumulative Data", with which you can choose how you want to view the data.
Figure 5-2 Monitoring the Managed Device
To see the statistics for the last interval (the default is 60 seconds), click the "Current Rates" radio button.
To see a chart of the statistics, click the "TopN Chart" radio button.
To see cumulative data from the managed device, click the "Cumulative Data" radio button.
