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. NAM supports only one managed device and Nexus 1010 only supports one NAM Virtual Blade as primary.

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.

To view the switch information, choose Setup > Managed Device > Device Information. The fields are described in Table 5-1, Switch Information.

Table 5-1 Switch Information 

Field	Description
SNMP Test information	Displays the IP address of the NAM and the switch that the SNMP test occurred on.
Name	Name of the switch.
Hardware	Hardware description of the switch.
Supervisor Software Version	Current software version of the Supervisor.
System Uptime	Total time the switch has been running.
Location	Physical location of the switch.
Contact	Contact name of the network administrator for the switch.
SNMP read from switch	SNMP read test result.
SNMP write to switch	SNMP write test result.
Mini-RMON on switch	For Cisco IOS devices, displays the status if there are any ports with Mini-RMON configured (Available) or not (Unavailable).
NBAR on switch	Displays if NBAR is available on the switch.
VLAN Traffic Statistics on Switch	Displays if VLAN data is Available or Unavailable. Note Catalyst 6500 Series switches require a Supervisor 2 or MSFC2 card.
NetFlow Status	For Catalyst 6500 Series devices running Cisco IOS, if NetFlow is configured on the switch, Remote export to NAM <address> on port <number> displays, otherwise the status will display Configuration unknown.

This section describes how to set router/managed device parameters.

Step 1 Choose Setup > Managed Device > Device Information.

The Router System Information displays as shown in Figure 5-1, Managed Device Information and Set Up PageManaged Device Information and Set Up PageManaged Device Information and Set Up Page.

Table 5-2, Router/Managed Device System Information. Some of the fields below may not be available when using a Nexus 1000V as a managed device.

Table 5-2 Router/Managed Device System Information 

Field	Description
Name	Name of the router.
Hardware	Hardware description of the router.
Managed Device Software Version	Current software version of the router.
Managed Device System Uptime	Total time the switch has been running.
Location	Physical location of the router.
Contact	Name of the network administrator for the router.
Managed Device	IP address of the router.
SNMP v1/v2c RW Community String	Name of the SNMP read-write community string configured on the router
Verify String	Verify the SNMP .
Enable SNMP V3	Check the check box to enable SNMP Version 3 (starting with NAM 5.0, you have the ability to manage devices with SNMPv3). If SNMPv3 is not enabled, the community string is used.
Mode: No Auth, No Priv	SNMP will be used in a mode with no authentication and no privacy.
Mode: Auth, No Priv	SNMP will be used in a mode with authentication, but no privacy.
Mode: Auth and Priv	SNMP will be used in a mode with both authentication and privacy.
User Name	Enter a username, which will match the username configured on the device.
Auth Password	Enter the authentication password associated with the username that was configured on the device. Verify the password.
Auth Algorithm	Choose the authentication standard which is configured on the device (MD5 or SHA-1).
Privacy Password	Enter the privacy password, which is configured on the device. Verify the password.
Privacy Algorithm	Enter the privacy algorithm, which is configured on the device (AES or DES).

Step 2 Click the Test Connectivity button to perform an SNMP test. Click Close when finished.

Step 3 Click Submit to submit the information and close the window.

Monitoring the Managed Device Interfaces

Monitoring the managed device interfaces provides per-interface statistics directly from the Nexus switch. Go to the Analyze > Managed Device > Interfaces (see Figure 5-1).

Figure 5-2 Interface Statistics

To change the interval, go to the Interactive Report on the left side of the screen and click the "Filter" button.
