Cisco Prime Network Analysis Module (NAM) gives network administrators a holistic view of how the network is performing and how users are experiencing the delivery of applications and services. Comprehensive visibility helps you to:
Optimize network resources
Troubleshoot performance issues
Deliver consistent performance levels
Cisco Prime NAM provides the following functionality:
Interactive dashboards with purpose-designed workflows, contextual navigation, and one-click captures
Comprehensive traffic statistics and application and voice/video performance metrics
Visibility into overlay networks such as OTV, LISP, and VXLAN
Detailed troubleshooting with insightful packet captures, advanced filters, and error scan
Centralized management with Cisco Prime Infrastructure

Support for Layer 7 application visibility
For new installations, deep packet inspection is the default. For upgrades, the default is dependent on 6.0(2) application classification mode. You can enable and disable this feature from the UI and CLI. NBAR2 release engine version is 18, library 3.12.
Adding More Detail into Dashboard and Application Reports
Protocol pack update capability
You can download updated protocol packs from the UI, CLI, or from Prime Infrastructure (if you have purchased this software).
Adding More Detail into Dashboard and Application Reports
Custom applications can be defined using an IP address range/prefix
Support has been added to use an IP address range/prefix.
Creating Custom Applications.
Improved application analysis workflows
Global search enables host entry which automatically displays an overall view of the host related data
Host conversations view
Improved sort and filter capabilities
Encapsulation Details view available from Top N Encapsulation dashboard
Custom filter management lets you save filters
Context drill-down links to Top N Analysis reports available from Monitor dashboards
Same access to context menus in Top 100 tables as in charts on dashboard pages
Understanding Prime NAM Behavior Reference
A user option is added to select if TOS information is used to make up a NAM network flow. If it is used, any change of TOS byte in an on-going flow results in a new flow being created. If it is not used, the entire flow transaction is treated as one flow regardless of the change of TOS in this flow.
If measuring type of service (DSCP) of the monitored traffic is necessary, please select TOS information as part of flow configuration. Otherwise, if ART and other flow based analysis is required, and you know in your network, the TOS information can change in an on-going flow, please don’t select TOS information as part of flow configuration.
Customizing Network Preferences
Changed or Removed Features
NBAR Protocol Directory MIB
This feature was supported on ISR routers and switches with the Catalyst 6500 Supervisor Engine 32 Programmable Intelligent Services Accelerator (PISA) running IOS 12.2(18)ZY (or later) and is no longer supported. NBAR-PD MIB is also no longer supported. Layer 7 application classification can be used instead.
Customizing Cisco Prime NAM
Deprecated.enc file support
Capture file format support no longer supports.enc file format. NAM uses.pcap format.
Understanding Capture Sessions
Deprecated Performance Agent remote data source support
Use of Performance Agent as a remote data source has been removed. This feature support is included in Prime Infrastructure.
See your Prime Infrastructure product documentation.
Changed Conversations page
Conversations page has been changed and is renamed to the Host Conversation page.

Supported Upgrade Paths
This section includes the supported upgrade paths to NAM 6.1.
Release 6.0(2) to 6.1
Release 6.0(1) to 6.1
Release 5.x to 6.1
For details about how to upgrade Prime NAM, see Upgrading to Cisco Prime NAM. This document contains upgrade commands that work across all supported releases. The information in this document is based on the 6.0(2) upgrade, but is valid for the upgrade to 6.1 for the above supported paths and platforms. Note that starting with this release, the NAM-1-250S and NAM-2-250S are no longer supported.
Note To improve the performance of monitoring Data Center protocols such as VxLAN, FabricPath, OTV, LISP, Segment ID, VNTag, and FCoE, we recommend that you upgrade the FPGA image in your Cisco Nexus 7000 Series NAM-NX1. For details on how to upgrade your FPGA image, see FPGA/EPLD Upgrade Note for Cisco Prime NAM-NX1, 6.0.
This section contains upgrade information you should review before completing your Cisco Prime NAM upgrade.
Upgrading Nexus 7000 Series NX-OS Software
Before you upgrade your Cisco Nexus 7000 Series NAM-NX1 software, we recommend that you first upgrade your Nexus 7000 Series software from 6.1(1) to 6.2 or above using the following procedure:
1. Save your configuration to boot flash.
2. Use config t to install the system and kickstart images:
boot system boot flash:<system image>, boot kickstart boot flash:<kickstart image>
3. Use write erase to erase nvram:
4. Use show boot to ensure the new image is loaded:
5. Enter reload to load the new image.
6. After the new image is loaded, copy your saved config back to flash.
If you are using Prime Infrastructure, certain releases support remote installation of protocol packs on NAM servers. See your Prime Infrastructure documentation for more details.
Some custom applications may display as blank or deleted after an upgrade from 5.x to 6.1.
Restrictions and Limitations
This section contains important restrictions and limitation as follows:
Encapsulation is limited to first 500 entries. You may be unable to view any context menus from the Encapsulations dashboard if you have more than 500 VLANs or VxLANs or wireless endpoints.
Report data is incorrect when the default for International Notation has been changed. We recommend that you do not change this administration preference. (CSCuo28432)
Software filters do not currently work on NBAR application IDs. The “Quick Capture” operation will not capture any packets if any of the packet data includes an NBAR application ID.
Avoid using SFP+ transceivers manufactured by JDSU (even Cisco-branded ones) in NAM-2320 appliances, as these have been found to exhibit compatibility issues with the NIC drivers shipped with the NAM 6.1 software. JDSU transceivers have a serial number with a "JUR" prefix. (CSCuv61643)
Known and Resolved Problems in Release 6.1
For a complete list of known and resolved bugs and enhancements for this release, use the Cisco Bug Search tool.
Cisco Bug Search
Bug Search Tool (BST), the online successor to Bug Toolkit, is designed to improve our customers' effectiveness in network risk management and device troubleshooting.
BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The service has provision to filter bugs based on credentials to provide external and internal bug views for the search input.
To use the BST to search for a specific bug or to search for all bugs in a release:
