Scenario 7: Using Nexus 1000V NAM VSB to Monitor Nexus 1000V Switch Environment
As networks and applications move into the virtualization environment, the challenge for administrators is finding
tools to gain insight into that environment. The NAM VSB provides that function by integrating with the Cisco Nexus
1010 virtualization appliance. Using the NAM VSB, the administrator gains operational visibility into the virtual
switching layer and is able to see virtual machine (VM) to VM statistics. See Figure 22.
Deployment: Applications are being deployed in the virtualized environment and the Nexus 1000V switch is
providing the network connectivity. The NAM VSB installed on the Nexus 1010 Virtual Services Appliance will be
used to monitor the environment.
Note:
If Nexus 1000V switches and NAMs are already deployed in the network, NAM upgraded to version 4.2 can
be utilized to monitor the switches through ERSPAN or NetFlow data sources to the NAM. The 1000V switch and
NAM should be directly connected to the same physical switch.
Figure 22. Cisco Nexus 1000V NAM Virtual Service Blade Deployment
Step 1. Install and configure NAM VSB on the Nexus 1010 Virtual Services Appliance. Refer to the Appendix,
“Installing and Using Cisco NAM.”
Step 2. Verify that ERSPAN or NetFlow are configured on the 1000V switch Virtual Supervisor Module (VSM)
providing data to NAM.
Step 3. Configure the ERSPAN or NetFlow data source on the NAM VSB.
Step 4. Enable all applicable monitoring parameters in NAM for ERSPAN and NetFlow. Figure 23 shows the
Overview page, displaying top N information, for example, applications, hosts, protocol, and server
response time. Navigation is provided to view and display details for each of the categories listed.
