Latest Release: NAM Software 5.1

Technical Overview

Q. How does the Cisco NAM with Software 5.1 work?
A. The Cisco NAM collects packets or flows (NetFlow Data Export [NDE]) being sent to it from the switch or router. The NAM parses the packets, gathers relevant data and stores processed information in the new Performance Database. This database provides valuable traffic information on voice, video, and data traffic, VLANs, Differentiated Services (DiffServ) configurations, hosts, conversation pairs, application usage, and application response times. This information is presented in the NAM's GUI in easy-to-read interactive reports.
The packets that the Cisco NAM collects are defined by the user's selecting one or more data sources. Data sources, which are features of the switch, router, or WAAS device, are described in Table 5. The Cisco NAM has independent backplane interfaces to collect SPAN/VACL traffic and NDE/WAAS/ERSPAN.

Table 3. Cisco Catalyst 6500 Series and Cisco 7600 Series NAM Traffic Sources

Traffic Source

Description

SPAN, Remote SPAN (RSPAN), and Encapsulated RSPAN (ERSPAN)

Using the SPAN, RSPAN, and ERSPAN capabilities of Cisco Catalyst 6500 Series Switches, traffic from ports, VLANs, and EtherChannel links can be mirrored to the NAM. The NAM collects statistics on all layers of network traffic spanned to it. RSPAN allows traffic to be collected from other RSPAN-enabled devices in the same VLAN Trunk Protocol (VTP) domain. ERSPAN allows traffic to be sent to the NAM using generic routing encapsulation (GRE) tunnels from a Layer 3 network.

VACLs

The NAM uses VACLs to capture or "filter" selected VLANs and WAN traffic (on Cisco IOS devices only) to the NAM ports. Additional filtering rules can also be applied to target specific data flows. The NAM must be specified as the capture destination for VACL entries when configuring the local supervisor.

NDE

NetFlow Data Export records offer an aggregate view of the network traffic. When enabled on the switch, the NetFlow data source becomes available on the Cisco NAM without the need to create any SPAN sessions. In addition, the NAM can receive NDE from remote devices for analysis.

WAAS

The NAM uses the built-in instrumentation on 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 NAM to measure application response time, transaction time, bandwidth usage, and LAN/WAN data throughput to accurately quantify the impact of Cisco WAAS optimizations.

Q. How does the Cisco NAM gain visibility into traffic from other switches/routers?
A. The LAN or WAN traffic from other devices can be directed to the NAM for analysis using RSPAN, ERSPAN, or NetFlow Data Exports.
Q. How does the Cisco NAM gain visibility into WAN traffic?
A. The NAM gains visibility into WAN traffic using VACL capture for WAN interfaces and NDE. VACL-based captures can be used (in supervisors running Cisco IOS Software in native mode) to monitor traffic from WAN interfaces. NDE from local and remote devices can be used to monitor WAN interfaces and provide application-level visibility into WAN segments.
Q. What is VACL capture and how does the Cisco NAM use it?
A. VACL capture is a data source that uses SPAN and fulfills similar functions. VACLs can be used to capture or "filter" selected VLANs and WAN traffic (with Cisco IOS Software). In Cisco IOS Software 12.2(18)SXF or later, VACLs can also be applied to WAN interfaces.
Q. How does the Cisco NAM with Software 5.1 use NetFlow?
A. The Cisco NAM supports monitoring of both packet- and NetFlow-based traffic sources using independent backplane interfaces. These two data sources complement each other to provide a powerful and comprehensive monitoring solution. NetFlow can be used to gain an extensive view of the traffic to analyze who is using your network, what applications they're using, and how much bandwidth is being consumed. For deeper analysis, it can be combined with packet data using traffic sources such as SPAN, VACL, ERSPAN, or RSPAN. Also, NetFlow can be used to obtain visibility into traffic where SPAN is not available (for example, WAN interfaces, remote router interfaces, and so on).
NetFlow can be enabled on interfaces of local or remote devices and sent to the NAM for analysis. As a consumer, the NAM can receive NetFlow packets on its management port from devices such as Cisco routers and switches. Those records are stored in its performance database as if that traffic had appeared on one of the NAM data ports. The NAM understands NetFlow versions 1, 5, 6, 7, 8, and 9. Incoming NetFlow data is parsed by the NAM, stored in its internal database, and presented in the GUI in the same way as traffic from other data sources.
Some network devices have more than one "engine" that is capable of independently exporting NetFlow. Depending upon features of the device, flows can be exported from multiple flow caches in the hardware and/or software. For example, supervisor and line cards may be able to export flows independently from their local caches. By default, NAM 5.1 will automatically create independent data sources for each engine exporting NetFlow records to NAM.
Q. Can the Cisco NAM collect NetFlow from remote WAN routers?
A. Yes. The Cisco NAM can collect and analyze NDE from remote devices including WAN routers. This feature is helpful in analyzing traffic on a WAN router connected to the Catalyst 6500 Series Switch or from remote WAN routers where ample bandwidth is available to send NDE.
Q. Does the Cisco NAM require a separate NetFlow data collector for monitoring?
A. No. The NAM collects and consumes NetFlow data for performance monitoring purposes.
Q. What versions of NetFlow does the Cisco Catalyst 6500 Series and Cisco 7600 Series NAM support?
A. The NAM supports versions 1, 5, 6, 7, 8, and 9.
Q. What release of Cisco IOS Software is required to support the Cisco Catalyst 6500 Series and Cisco 7600 Series NAM?
A. The Cisco NAM requires any feature license in Cisco IOS Software Release 12.2(18)SXF (or later) or Cisco Catalyst Operating System 8.2(1) (or later). Please refer to the Cisco NAM Release Notes for extensive information on the required system software.
Q. How is the Cisco NAM secured?
A. The Cisco NAM can be secured with up to 256-bit encryption. The NAM also supports role-based user authorization and authentication locally or using TACACS+.
Q. Can NAM-1 or NAM-2 be deployed in fabric-enabled Cisco Catalyst 6500 Switches or Cisco 7600 Series without affecting switch performance?
A. Yes. NAM-1 and NAM-2 support full fabric (crossbar) connectivity and can be deployed in a fabric-enabled chassis with no impact on switching performance.
Q. Can multiple Cisco NAMs be installed in a Cisco Catalyst 6500 Series or Cisco 7600 Series chassis?
A. Yes. Multiple Cisco NAMs can be installed in a single chassis.
Q. Can the Cisco NAM be installed in a Cisco Catalyst 6500 Series or Cisco 7600 Series chassis with other services modules (for example, the Firewall Services Module [FWSM])?
A. Yes. The Cisco NAM can be installed with other services modules.
Q. Are there any ports or network interfaces on the Cisco NAM?
A. No.
Q. Can multiple VLANs be spanned to the Cisco NAM?
A. Yes. The NAM is fully compatible with the SMON MIB and supports the monitoring of multiple VLANs.
Q. Does the Cisco NAM support supervisor failover?
A. Yes.
Q. If a switch chassis is upgraded, must a new Cisco NAM be purchased?
A. No. The Cisco NAM is fully functional in any of the modular Cisco Catalyst 6500 or 6000 Series chassis and Cisco 7600 Series chassis.
Q. Does the NAM support Virtual Switch System on the Catalyst 6500?
A. Yes, all Catalyst 6500 NAMs and NAM Appliances support VSS.
Q. Which NAM and Cisco IOS Software releases support VSS?
A. On the Catalyst 6500 NAM-1 and NAM-2, VSS is supported in NAM 3.6.1a or later with Cisco IOS Software Release 12.2(33)SXH(1) or later. On the Catalyst 6500 NAM-1-250S and NAM-2-250S, VSS is supported in NAM 3.6.1b or later with Cisco IOS Software Release 12.2(33)SXH(1) or later. On the NAM Appliances, VSS is supported in NAM 4.0 or later with Cisco IOS Software Release 12.2(33)SXH(1) or later.
Q. Are there specific capabilities that NAM provides in a VSS environment that are distinct from the capabilities provided in a non-VSS environment?
A. Yes, there are three key differentiators:

• Monitoring port statistics on both switches using one NAM. The NAM can provide mini-RMON statistics on both switches and identifies these statistics by chassis, slot, and port. In this way, a complete view of Layer 2 traffic utilization can be obtained to assist in quickly identifying potential bottlenecks.

• Using SPAN on one NAM to obtain visibility into traffic on both virtual switches. Typically, RSPAN or NetFlow would need to be used to obtain visibility into an adjacent switch.

• Monitoring the health of both switches using a single NAM.

Q. What device does the Cisco Catalyst 6500 NAM monitor in the virtualized data center?
A. The Cisco Catalyst 6500 NAM can extend its visibility into the Cisco Nexus 1000V switch in deployment scenarios where the Cisco Catalyst 6500 is an End-of-Row (EoR) access switching platform in the virtualized data center. The Cisco Nexus 1000V switch is a software switch on a server that delivers Cisco Virtual Network Link (VN-Link) services to VMs hosted on the server. This distributed switch has two major components: the Virtual Ethernet Module (VEM) and the Virtual Supervisor Module (VSM), which manages the VEMs. The Cisco Nexus 1000V can be configured to direct NetFlow Data Export from virtual or physical interfaces on the Nexus VEM to the Cisco Catalyst 6500 NAM. Also, ERSPAN can be configured to enable the Cisco Catalyst 6500 NAM to remotely monitor the traffic in the VM network.
Q. What NAM data sources can be used to monitor traffic in the Cisco Nexus 1000V switch environment?
A. As previewed in the answer above, the Cisco Catalyst 6500 NAM can monitor the Cisco Nexus 1000V using ERSPAN and NetFlow data sources (for more information about these NAM data sources, please refer to Table 5 of this Q&A). ERSPAN can be configured on the Cisco Nexus 1000V to enable the Cisco NAM to obtain visibility into specific ports or VLANs. The data made available by ERSPAN permits the NAM to provide core traffic usage metrics (on applications, hosts, and conversations), response time analytics, and QoS and VLAN monitoring statistics. NetFlow Data Export can be configured on select virtual and physical interfaces of the Cisco Nexus 1000V. The data made available by NetFlow permits the NAM to provide core traffic analytics and QoS monitoring statistics.
Q. Where should I deploy the Cisco Catalyst 6500 NAM to obtain visibility into the virtualized data center?
A. The Cisco Catalyst 6500 NAM is ideally deployed in an EoR Catalyst 6500 switch. Using the ERSPAN data source from the Cisco Nexus 1000V, headers of designated traffic flows (by port or VLAN) are encapsulated in a GRE tunnel and forwarded to the Cisco NAM for analysis.
Q. When would I purchase a Cisco Catalyst 6500 NAM vs. a Cisco Nexus 1000V NAM VSB?
A. The Cisco Catalyst 6500 NAM is a hardware module integrated in the Cisco Catalyst 6500 that provides visibility into both physical and virtual networks. It comes with a feature set and level of performance commensurate with providing high-performance monitoring and troubleshooting in the campus or data center. Cisco Prime NAM for Nexus 1010 is a software integrated in the Cisco Nexus 1010 Virtual Service Appliance. Cisco Prime NAM for Nexus 1010 comes with a feature set and level of performance that is specifically targeted for monitoring and troubleshooting the Cisco Nexus 1000V environment. Cisco Prime NAM for Nexus 1010 is a perfect fit for customers who are deploying the Cisco Nexus 1010, offering both ease of deployment and investment value. For those customers who have Cisco Catalyst 6500s, who may want to monitor more than the Cisco Nexus 1000V environment, who require higher overall performance, and/or who perform extensive captures and decodes will want to consider the Cisco Catalyst 6500 NAM. Additionally, the Catalyst 6500 NAM should be considered if a Cisco Catalyst 6500 is deployed in the data center access layer in VSS mode for high availability considerations. In this deployment scenario the Cisco Catalyst 6500 NAM can monitor switch ports and associated application traffic on both the Cisco Catalyst 6500 and on the Cisco Nexus 1000V.
Q. What protocols does the Cisco NAM monitor?
A. The Cisco NAM monitors several hundred unique protocols, including those defined in RFC 2896, and several Cisco proprietary protocols. In addition, the NAM can automatically detect unknown protocols and offers users the flexibility to customize the protocol directory to meet their specific requirements. Examples of protocols supported by the Cisco NAM for monitoring follow:

• TCP and User Datagram Protocol (UDP) over IP including IPv6

• HTTP and HTTPS

• VoIP including Skinny Client Control Protocol (SCCP), RTP/Real-Time Control Protocol (RTCP), Media Gateway Control Protocol (MGCP), and Session Initiation Protocol (SIP)
