Q. What is the Cisco Nexus® 7000 Series Network Analysis Module (NAM-NX1) and what does it do?
A. Integrated with the Cisco Nexus 7000 Series Switches, the Cisco® NAM-NX1 is a high-performance service module that delivers comprehensive application awareness, performance analytics, and network intelligence to simplify data center operations. The module empowers network administrators with actionable details to improve application performance, optimize network resources, and enhance operation efficiency.
Comprehensive application awareness in combination with performance analytics allows administrators to quickly focus on business-critical applications and help ensure that applications are getting adequate network resources and performing at optimal levels.
The extension of network visibility to virtualization and overlay technologies such as Cisco Overlay Transport Virtualization (OTV), Locator/ID Separation Protocol (LISP), and Virtual Extensible LAN (VXLAN) enables administrators to optimize the network for distributed and efficient services delivery. For instance, in OTV environments, the NAM can look inside each overlay to provide traffic statistics and application performance metrics, categorized by host, application, and conversation. This approach allows administrators to effectively use network overlays and troubleshoot deployment problems.
The Cisco NAM-NX1 combines comprehensive data collection and analytics and a remotely accessible, web-based management console on a single blade that is installed in Cisco Nexus 7000 Series Switches. The console provides predesigned reports, workflows, and contextual navigation to expedite problem resolution and optimization decisions. It also includes an embedded performance database that preserves historical data, allowing you to understand what happened in the past when an event that affected network performance occurred.
Q. What are the business benefits of deploying the Cisco NAM-NX1?
A. The Cisco NAM-NX1 delivers comprehensive application awareness, performance analytics, and network intelligence to simplify data center operations. Table 1 provides an overview of the business benefits.

Q. Why is Cisco introducing an integrated solution?
A. As an extension to Cisco Unified Fabric and integrated with Cisco Nexus 7000 Series Switches, the Cisco NAM-NX1 delivers intelligence from both application and network perspectives that allows administrators to take full advantage of the fabric for efficient service delivery in a distributed environment. Today, virtualized data centers are dynamic, making it even more important to ensure service availability and consistent application experience for end users. Because it is an integrated solution, the Cisco NAM-NX1 can gather the packets from the backplane continuously or on demand, look more deeply into the packet, and deliver application performance and network analytics in real time. It empowers network administrators with actionable visibility to improve application performance, optimize network resources, and enhance operation efficiency. Additional benefits of integration include a reduced network footprint, lower administrative costs, simplified manageability, and tighter data integration with the switch.
Q. How does the Cisco NAM-NX1 simplify data center operations?
A. Today, virtualized data centers are dynamic, making it even more important to ensure service availability and consistent application experience for end users. The Cisco NAM-NX1 delivers comprehensive application awareness and deeper network analytics to help simply data center operations in many ways:
• Performance Analytics: Monitor the application experience and isolate the cause of latency to the network, server, or application in the event of performance degradation. Preempt performance problems with threshold-based proactive alerts to reduce downtime and failures.
• Workload mobility: Gain deeper insight into virtualization and overlay technologies such as OTV, LISP, and VXLAN to optimally design the network for distributed and efficient services delivery.
• Operation agility: Improve operation productivity with a service-focused approach, analyzing data in the context of the specific application, site, client, and server and transparently extending visibility across physical and virtual environments. Interactive reports, contextual navigation, and other features help accelerate resolution of performance problems.
• Security: Validate Cisco TrustSec® policy by evaluating endpoints and hosts, applications, and conversations in one or more security groups. Also, analyze traffic-flow patterns to isolate suspected security problems.
Q. How does the Cisco NAM-NX1 gather information from the network?
A. The Cisco NAM-NX1 supports a broad variety of data sources (Table 2) to gather information from the network. For example, the Cisco NAM-NX1 collects packets from network devices using mechanisms such as Switched Port Analyzer (SPAN), Remote SPAN (RSPAN), and Encapsulated RSPAN (ERSPAN) and traffic flow information using NetFlow Data Exports (NDE). The Cisco NAM-NX1 processes the information, extracts relevant details, and computes performance and use analytics and stores this data in the built-in performance database. This database provides valuable information about voice, video, and data traffic; VLANs; VXLANs; OTV; Differentiated Services (DiffServ); hosts; conversation pairs; application bandwidth use; etc. This information is presented in the NAM's GUI for analysis with easy-to-navigate interactive reports. In addition to the computed analytics, the Cisco NAM-NX1 can store packet captures, allowing you to resolve complex application performance problems.
Table 2. Cisco NAM-NX1 Data Sources
SPAN, RSPAN, and ERSPAN
Using the SPAN, RSPAN, and ERSPAN capabilities of Cisco Nexus switches, traffic from ports and VLANs can be mirrored to the NAM. ERSPAN allows traffic to be sent to the NAM using generic routing encapsulation (GRE) tunnels from a Layer 3 network.
NetFlow Data Export (NDE)
NDE records offer an aggregate view of the network traffic. When enabled on the switch, the Cisco NAM-NX1 can be configured as the destination. In addition, the NAM can receive NDE records from remote devices for analysis.
The Cisco NAM-NX1 uses the built-in instrumentation in Cisco WAAS to gather information about the optimized and pass-through traffic to provide end-to-end application performance visibility in a Cisco WAAS environment. The information allows the NAM to measure the application response time, transaction time, bandwidth use, and LAN and WAN data throughput to accurately monitor and quantify the impact of Cisco WAAS optimizations.
Q. What version of Cisco NX-OS Software is required to support the Cisco NAM-NX1?
A. Cisco NAM-NX1 requires Cisco NXOS Software Release 6.2.
Q. How is the Cisco NAM-NX1 secured?
