Q. What are the primary differences between the Cisco NAM 2220 Appliance and the Cisco NAM 2204 Appliance?
A. The NAM 2220 and the NAM 2204 share a similar hardware foundation and the same software application, but differ in the following important ways:

The NAM 2220 includes a more powerful processor and a faster packet processing engine that provides more than four times the monitoring performance of the NAM 2204.

The NAM 2220 includes higher density storage commensurate with its higher monitoring performance. Two of the NAM 2220’s six SAS drives support RAID 1 to minimize downtime. The other four support RAID 0 to improve the speed at which capture data are written to the drives.

The NAM 2220 includes an option for a redundant power supply. When a redundant power supply is available, the unit will continue to operate should a power supply fail, and the failed power supply can be replaced without having to power-down the unit.

The NAM 2220 supports up to two 10 Gigabit Ethernet optical connections. The NAM 2204 supports up to four each of either 10/100/1000 RJ-45 connections or 1 Gigabit Ethernet optical connections.

The form factor of the NAM 2220 is 2 rack units (RUs); the NAM 2204 is 1 RU.

As a result of the NAM 2220’s higher monitoring performance, it offers higher scalability, supporting the monitoring of a larger number of conversations, Real Time Protocol (RTP) streams, WAAS connections, NetFlow records, and so on.

Q. Is the Cisco NAM 2204 upgradeable to the Cisco NAM 2220?
A. No. The NAM 2204 and the NAM 2220 have fixed configurations and cannot be transformed from one version to the other.
Q. What is the Cisco NAM Traffic Analyzer?
A. The Cisco NAM includes embedded software, called the Cisco NAM Traffic Analyzer, which analyzes and stores the data and presents the data to clients using a supported web browser.
Q. Where can the Cisco NAM 2200 Series Appliances be deployed in the network?
A. The Cisco NAM 2200 Series Appliances are dedicated performance monitoring instrumentation and connect to the Switched Port Analyzer (SPAN) ports of a switch using copper or fiber optical interface modules. They can also connect to critical network links using third-party passive inline taps. They can be deployed in multiple places in the network and complement Cisco NAM blades to provide extensive network visibility. The Cisco NAM Appliances can be deployed at LAN aggregation points, for example, in the campus core and distribution layers, for always-on performance management; at services points, for example, in data centers or Cisco Unified Communications Manager clusters in IP telephony networks, where assuring application delivery is critical; and in important access points, close to servers, key clients, in IP phone closets, where traffic monitoring is essential. They can also be deployed at WAN edges.

A. No. Enforceable licensing applies to the Cisco WAAS NAM Virtual Blade product offering only at this time.

Technical Overview

Q. How does the Cisco NAM work?
A. The Cisco NAM collects packets or flows (NetFlow Data Export [NDE]) being sent to it from the switch, router, WAE device, or tap. The NAM parses the packets and extracts data to populate standards-based MIBs and proprietary extensions included in the NAM. These MIBs and extensions provide 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 Traffic Analyzer GUI in easy-to-read real-time and historical reports. It can also be accessed using a standards-based centralized Simple Network Management Protocol (SNMP) console or exported to third-party tools using comma-separated value (CSV) format and other mechanisms to build additional value for enterprisewide performance assurance and reporting.

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 and include SPAN, Remote SPAN (RSPAN), Encapsulated RSPAN (ERSPAN), VLAN Access Control List (VACL) capture, NDE, and WAAS Flow Agent. The tap data source is described in detail in a Q&A that appears later in this document.

Table 5. Cisco NAM 2200 Series Appliances Data Sources

Data Source



Using the SPAN, RSPAN, and ERSPAN capabilities of Cisco switches and routers, 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 encapsulated GRE tunnels from a Layer 3 network.


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.


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 Flow Agent

The NAM gathers WAAS Flow Agent data for optimized and pass-through traffic to provide end-to-end application performance visibility in a Cisco WAAS environment. The Flow Agent data enables 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 do the Cisco NAM Appliances gain visibility into traffic from more than one switch or router concurrently?
A. There are multiple ways to gain visibility into traffic from more than one device with the Cisco NAM Appliances:

The NAM Appliances include more than one monitoring interface, which enable them to collect traffic from more than one device.

The NAM Appliances can be used with a passive inline tap to monitor traffic from/between multiple devices.

The LAN or WAN traffic from other devices can be directed to the NAM Appliances for analysis using RSPAN, ERSPAN, or NDE.

Q. How many monitoring ports do the Cisco NAM Appliances support?
A. The NAM Appliances support the following number of monitoring ports:

Up to two 10 Gigabit Ethernet monitoring ports on the NAM 2220

Up to four 1 Gigabit Ethernet monitoring ports on the NAM 2204

Q. What data sources are received on the monitoring ports? On the management port?
A. The following data sources are received on the:

Monitoring ports: SPAN, RSPAN, VACL capture, tap

Management port: ERSPAN, NDE, WAAS Flow Agent

Q. Is there a limit on the number of SPAN sessions that the NAM Appliances can support?
A. The NAM 2204 Appliance has four physical monitoring interfaces and can monitor up to four switches using SPAN at one time. The NAM 2220 has two physical monitoring interfaces and can monitor up to two switches using SPAN at one time. Since the switch currently offers support for up to two SPAN sessions, the NAM 2204 can monitor one SPAN session each on four switches or two SPAN sessions each on two switches. The NAM 2220 can monitor one SPAN session each on two switches or two SPAN sessions each on one switch. The NAMs also have an ALLSPAN capability, which enables traffic collected from all physical interfaces on the appliances to be viewed as an aggregate.
Q. What are RAID 0 and RAID 1, and how do the appliances use RAID?
A. RAID, which stands for Redundant Array of Independent Disks, is a technology that employs the simultaneous use of two or more hard disk drives to achieve greater levels of performance, reliability, or larger data volume sizes. Redundancy is a way that extra data is written across the array, which is organized so that the failure of one disk (or sometimes more) in the array will not result in loss of data. A failed disk may be replaced by a new one, and the data on it reconstructed from the remaining data and the extra data. A redundant array allows less data to be stored. There are various combinations of these approaches giving different trade-offs of protection against data loss, capacity, and speed. RAID levels 0, 1, and 5 are the most commonly found, and cover most requirements. RAID 0 (striped disks) distributes data across several disks in a way that gives improved speed and full capacity, but all data on all disks will be lost if any one disk fails. RAID 1 (mirrored disks) could be described as a real-time backup solution. Two (or more) disks each store exactly the same data, at the same time, and at all times. Data is not lost as long as one disk survives. Total capacity of the array is simply the capacity of one disk. At any given instant, each disk in the array is simply identical to every other disk in the array.
The NAM 2220 Appliance uses both RAID 0 and RAID 1. RAID 0 is used on the four drives that support the storage of packet capture data. RAID 1 is used on the two drives that store the NAM operating system and reports data. The NAM 2204 Appliance does not use RAID.
Q. What is a managed device?
A. Typically, performance monitoring appliances have little to no knowledge of the devices that they are monitoring. The NAM blade on the other hand, as integrated instrumentation, automatically exchanges information with the device hosting it to learn about that device. This simplifies a number of configuration and monitoring tasks and also allows the NAM blade to provide critical health information about the hosted device. To duplicate this experience with the NAM 2200 Series Appliances, the concept of a managed device has been introduced. The managed device concept permits the creation of a communications channel between one of the devices being monitored and the NAM appliance. When a device is specified as the managed device, various configuration and monitoring tasks, such as configuring SPAN using the NAM GUI, can be more readily implemented, thus improving the user experience.
Q. What interface modules are supported for each NAM Appliances platform?
A. The interface modules supported for each NAM Appliance platform are indicated in Table 6.

Table 6. Supported Interface Modules

NAM Model

Monitoring Ports

Interface Modules PN


NAM 2220

Up to two


10 GE XFP 850 nm SR

NAM 2204-SFP

Up to four




GE SFP SX Transceiver


GE FP LX/LH Transceiver


Up to four


RJ45 10/100/1000

Q. Can these interface modules be mixed?
A. The interface modules can be mixed, but per platform only. For example, if a NAM2204-SFP is purchased, two GLC-Ts and two GLC-SX-MMs can also be purchased. However, if the same model is purchased and if two XFP-10GBASE-SRs are also purchased, these particular interface adapters will not work with this appliance model, although they’ll work with the NAM 2220 model.
Q. Must I purchase the XFPs from Cisco or can I purchase them elsewhere?
A. They can be purchased elsewhere, if desired. The qualified manufacturers of the XFPs are included in Appendix B of the Installation and Configuration Guide for the Cisco NAM 2220 Appliance at: It should be noted that if the XFPs are purchased from any other source but Cisco, no Cisco SMARTnet support is provided for maintenance of these items.
Q. Can you provide more information regarding the use of a tap as a data source?
A. Yes. A tap device can be used to obtain a copy of traffic flows between two network devices. Passive taps, such as optical tap devices, help ensure that the flowing traffic is not altered regardless of its connection to the NAM Appliance and provide a very low point of failure. Traffic flows will be interrupted while you connect a tap, but doing so should take less than a minute and can be done during a network maintenance window. NAM Appliances are designed to receive tapped network traffic from both directions, from multiple links simultaneously, and accurately merge received traffic to a single stream for high precision analysis.
Q. What taps does Cisco recommend that I use with my NAM Appliances?
A. Cisco has tested several taps that can be used with the NAM 2204 and NAM 2220 Appliances. These taps are identified in Appendix B of the Installation and Configuration Guide for the Cisco NAM 2204 Appliance and Appendix B of the Installation and Configuration Guide for the Cisco NAM 2220 Appliance. These documents can be found at and, respectively. Additional taps from the same vendors or taps from other vendors may also support the NAM Appliances, but they have not specifically been tested by Cisco.
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. How is the Cisco NAM Traffic Analyzer secured?
A. The Cisco NAM Traffic Analyzer can be secured with up to 168-bit encryption. The NAM also supports role-based user authorization and authentication locally or using TACACS+.
Q. Can multiple VLANs be spanned to the Cisco NAM?
A. Yes. The NAM is fully compatible with the switch monitoring (SMON) MIB and supports the monitoring of multiple VLANs.
Q. Does the NAM support Virtual Switch System (VSS) on the Catalyst 6500?
A. Yes, all Catalyst 6500 NAMs and NAM Appliances support VSS.
Q. Which NAM and IOS software releases enable VSS support?
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.

Leveraging 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 the traffic running on an adjacent switch.

Monitoring the health of both switches using a single NAM.

Q. How is the NAM appliance connected to the switch/switches in a VSS environment?
A. The NAM 2204 has four monitoring interfaces. One or more of these interfaces can be connected to one or more ports on each switch to provide full visibility. The NAM 2220 has two 10 Gigabit Ethernet monitoring interfaces. One of the two interfaces can be connected to a 10 Gigabit Ethernet port on each switch to analyze traffic from multiple VLANs/1 Gigabit Ethernet ports (spanned to the 10 Gigabit Ethernet port) in a VSS environment.

Software Features

Q. Can packet captures be saved and, if so, where?
A. Yes. The Cisco NAM offers two options to save capture data. Captures that have been stored in the NAM’s buffer can be saved to the NAM’s local hard drive for real-time analysis or analysis at a later date. In addition, captures can be saved directly to a remote network file server (NFS) or Small Computer System Interface over IP (iSCSI)–supported device. Saving captures on a remote storage device allows the user to capture very large amounts of raw data, which can then be analyzed remotely by NAM.
Q. Does the Cisco NAM perform historical traffic analysis?
A. Yes. The Cisco NAM Traffic Analyzer can display, store, and retrieve historical statistics on selected network traffic for up to 100 days. The export of historical reports can be scheduled or exported on demand. Reports can be sent by email or FTP and export formats can include CSV, XML, PDF, and HTML. In addition, standards-based applications can retrieve rich performance data from the NAM to provide enterprisewide reporting, trending, capacity planning, and baselining.
Q. Does Cisco NAM support voice monitoring for Cisco VoIP deployments only?
A. No. Cisco NAM monitors Real-Time Monitoring Protocol and thus, by extension, can provide reporting on any VoIP protocol that runs on top of RTP, a Layer 4 protocol.
Q. Which VoIP signaling protocols does the Cisco NAM support?
A. Cisco NAM supports a breadth of standards-based VoIP signaling protocols namely, Skinny Client Control Protocol (SCCP), Session Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP), and H.323.
Q. What are the key performance indicators for monitoring voice?
A. Cisco NAM offers real-time voice quality monitoring using standards-based Mean Opinion Score (MOS) and key performance indicators such as jitter and packet loss. It calculates MOS based on ITU-T G.107 recommendations.
Q. Can I identify the phones affected by voice quality degradation?
A. Yes. Cisco NAM allows the administrator to pinpoint the individual RTP stream experiencing voice quality degradation. By correlating the RTP and signaling streams, Cisco NAM can report the phone numbers and alias for each endpoint.
Q. What Cisco Unified Communications Management Solutions support NAM?
A. The solutions are Cisco Unified Service Monitor and Cisco Unified Operations Manager.
Q. What Cisco Unified Service Monitor and Cisco Unified Operations Manager versions first support NAM 4.x? Are these versions available today? If not, when will they be available?
A. The versions are Cisco Unified Service Monitor 2.2 and Cisco Unified Operations Manager 2.2. They are not available today. They are targeted for availability in the third quarter of 2009.
Q. How do Cisco Unified Service Monitor and Cisco Unified Operations Manager support NAM?
A. Cisco Unified Service Monitor collects voice metrics from multiple NAMs to provide enterprisewide visibility into voice quality. Cisco Unified Service Monitor generates alerts on the voice quality degradation that is reported by Cisco Unified Operations Manager. Based on these alerts, Cisco Unified Operations Manager allows the user to navigate into NAM to glean near real-time views of both voice and network performance to perform rapid troubleshooting.
Q. What is the Cisco NAM IAP feature?
A. The NAM intelligent application performance (IAP) feature offers comprehensive performance measurements for TCP-based applications to accurately characterize the end-user experience. This NAM 4.x feature offers a number of useful application performance indicators to facilitate faster problem identification. For example, the source of network latency affecting the end-user experience can be isolated by analyzing network delay metrics, namely client network delay, server network delay, and network delay. Similarly, server resource issues can be identified by network metrics such as application delay and server response time. In addition, the administrator can configure thresholds on these metrics to proactively detect performance degradations before they affect end users.
Q. How does Cisco NAM support Cisco WAAS?
A. Cisco NAM uses the built-in instrumentation of the Cisco Wide Area Application Engine devices as a data source to gather information on the optimized traffic to provide end-to-end application performance visibility in a Cisco WAAS environment. It measures application response time, transaction time, bandwidth usage, and LAN/WAN data, and so on to provide end-to-end application performance metrics, accurately quantifying the impact of WAAS optimization and helping to validate ongoing optimization improvements. NAM is also able to identify the applications that would benefit the most from deploying Cisco WAAS. Analyzing response time data over a period of time, the administrator can identify the applications where optimization can result in a material increase in available bandwidth.

Third-Party Reporting

Q. Does Cisco NAM include an API to allow partner reporting applications to use NAM as a data source?
A. Yes, the Cisco NAM includes multiple mechanisms, such as SNMP and CSV/HTTP that allow third-party management applications to retrieve data for networkwide reporting, trending, baselining, and capacity planning. The reporting application can retrieve monitoring data such as IAP, RMON, and Differentiated Services Monitoring (DSMON). To access the CSV/HTTP API, the partner must be a member of the Cisco Technology Developer Program and must apply to integrate its product with Cisco NAM.
Q. How can a partner apply for approval to use the Cisco NAM CSV/HTTP API for integration?
A. A partner can enroll in the Cisco Technology Developer Program at During the enrollment process, the partner must select Network and Service Management as the solution technology and Cisco NAM as the network management product for integration. Once the partners are approved and have signed the nondisclosure agreement (NDA) as well as the NAM developer license agreement, they will receive the API for integration.
Q. Does NetQoS SuperAgent support Cisco NAM 4.x as a data source?
A. Yes. With software release 4.x, Cisco NAM 2200 Series Appliances can export application response time data to NetQoS SuperAgent 8.1 or later for consolidated networkwide reporting. The comprehensive performance overview provided by NetQoS SuperAgent complements the granular performance information provided by Cisco NAMs to enable visibility into how applications are being delivered enterprisewide, yet isolate and resolve delivery problems proactively and promptly at their source.
