New Features and Enhancements in NAM 4.2
Visibility into Virtual Machine (VM) Network
NAM 4.2 software enables network administrators to extend operational visibility into the VM network including interactions across virtual machines. The feature can be used with NAM appliances, the Catalyst 6500 NAM blade, or the newly introduced Nexus 1000V NAM Virtual Service Blade, deployed in Data Center in conjunction with Nexus 1000V switch deployments. NAM supports the use of embedded management features, namely Encapsulated Remote Switched Port Analyzer (ERSPAN) and NetFlow, on the Cisco Nexus 1000V Switch. ERSPAN can be configured on the Cisco Nexus 1000V switch to allow NAM to obtain visibility into specific ports or VLANs. NetFlow Data Export can be configured on select virtual and physical interfaces to provide insight into traffic behavior in the virtual machine network.
Key benefits include:
•
•
•
•
As a distinctive advantage, NAM allows monitoring of virtual machines live while they migrate with VMotion.
New Cisco Nexus 1000V NAM Virtual Service Blade (VSB)
The Cisco Nexus 1010 Virtual Services Appliance has an integrated Cisco NAM VSB solution to monitor and troubleshoot the Cisco Nexus 1000V environment. As an integrated solution, the Cisco NAM VSB is ideal for customers who are deploying the Cisco Nexus 1010 Virtual Services Appliance, thereby providing greater investment protection, ease of deployment, and reduced network footprint.

Using NME-NAMs with Cisco Integrated Services Routers
This section describes the requirements to use NME-NAMs with Cisco Integrated Services Router (ISR) and ISR Generation Two (G2) Platforms.
You can deploy the NME-NAM-120S and NME-NAM-80S in any network module slot in the Cisco router platforms indicated in Table 2. A Network Module (NM) Adapter Card, SM-NM-ADPTR, is required to successfully integrate the NME-NAM into supported ISR G2 platforms. The NME-NAM supports the router platforms using NAM 3.6 or later. See Table 4, Minimum Cisco ISR and ISR G2 IOS Versions Required for NAM 4.2, for the minimum IOS software requirements to support NME-NAM. Only one Cisco NAM can be installed in a Cisco branch router.
To install an NME-NAM-120S network module in supported ISR G2 platforms using the NM Adapter Card, see Installing Cisco Network Modules and Service Modules, section "Using Network Modules in Service Module Slots on Cisco 2900 Series and Cisco 3900 Series Routers":

The memory requirements for the Nexus 1010 Virtual Services Appliance are built into the NAM image. This requires 2048Mb of memory available for the NAM on installation.
NetFlow Records
The NAM can display byte and packet counts of hosts, apps, and conversations based on a NetFlow Version 8 (and earlier) or Version 9 format. It assumes that the following fields (and IDs) are present:
•
•
•
•
•
•
•

•
Any custom templates by any device, for example an ASA security-oriented template, are not supported.
Catalyst 6500 NAM-1 and NAM-2 Memory Recommendation
To optimize the performance of NAM software, particularly of NAM 4.x releases given new features that can have large table sizes, Cisco offers a field-installable memory upgrade kit that can be purchased for WS-SVC-NAM-1 and WS-SVC-NAM-2 devices. The memory upgrade kit comes with 2GB of DRAM. Its part number is MEM-C6KNAM-2GB=.
Cisco has characterized that the memory upgrade can increase the number of hosts and conversations that can be monitored by up to a factor of two (the improvement can vary depending on packet sizes monitored, burstiness of traffic, NAM features enabled, switch/router features enabled, and so on). The memory upgrade not only can improve the number of hosts and conversations monitored, but also, as a result of the foregoing, can increase the number of concurrent flows that can be monitored. This can result in improved NAM performance when the NAM is deployed in places in the network where it can see a large number of concurrent flows.
You can find information about how to upgrade your memory in the document NAM Memory Upgrade Install Note at the following URL:
http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/hardware/Config_Notes/
78_18630.htmlNo memory upgrade kit is offered for the WS-SVC-NAM-1-250S and WS-SVC-NAM-2-250S, which already ship from factory with 2GB DRAM.

4.0-Rel 6.0.9 or later
WS-SVC-NAM-2
Before upgrading WS-SVC-NAM-1 or WS-SVC-NAM-2 from the NAM 3.6 release to NAM 4.2, the BIOS image in the NAM must be checked to determine whether it is running version 6.0.9 or later. If it is, NAM 3.6 can be upgraded to NAM 4.2 without upgrading the BIOS image. If it is not, the BIOS image must be upgraded. If the BIOS is not upgraded before installing NAM 4.2, NAM 4.2 will cause the NAM to lock up.
The BIOS image is bundled with the NAM's maintenance image. The maintenance image must first be upgraded and then the BIOS image. The new BIOS will take effect only after the NAM is rebooted following the maintenance image and BIOS image upgrades.

NAM Virtual Service Blade Licensing Requirements
NAM Virtual Service Blade (VSB) software (for either the WAAS or the Nexus 1010 Virtual Services Appliance) requires you to install a product license in the form of a text file. An evaluation license allows you to use the software for up to 60 days, but you will be unable to log in to the NAM GUI after the evaluation license expires. When using an evaluation license, the NAM login window indicates how many days remain before the evaluation license expires.
On the Nexus 1010 Virtual Services Appliance, node-locking information is obtained from the host appliance during NAM installation and is not configurable.
For the NAM on WAAS, you can provide licensing information, also known as node-locking information, during software installation or after software installation using the NAM CLI. During the NAM software installation, you will be prompted to enter a product identifier (PID) and serial number (SN).
To obtain a NAM VSB license, go to the following URL:
http://www.cisco.com/go/license
Follow the instructions on this page to obtain a NAM VSB license file. You will need the appliance PID and SN to obtain the license file. After you enter the PID and SN or the Product Authorization Key, a license file will be sent to you by e-mail. Store this license file on an available FTP server. Use the license install command to install the license after the NAM software installation completes.

Note
Supported Upgrades
NAM 4.2 supports upgrades from the NAM 4.0 and NAM 4.1 software releases (with any patches) on the following NAM devices:
•
•
•
•
•
•
NAM 4.2 supports upgrades from the NAM 4.0 and NAM 4.1 software release (with any patches) on the following Cisco NAM 2200 Series appliances:
•
•
•
NAM 4.2 also supports upgrade from the NAM 4.1 software release (with any patches) on the following WAAS Blades:
•
•
NAM 4.2 does not support upgrades from NAM 3.6 or below. However you can reinstall NAM 4.2. See the next section, Reinstalling NAM Software.
Reinstalling NAM Software
Although you cannot upgrade from a version prior to NAM 3.6, you can do a re-install instead using the upgrade command and the --install option. See the Catalyst 6500 Series Switch and Cisco 7600 Series Router Network Analysis Module Installation and Configuration Note at the following URL for more information:
When you re-install software with NAM 4.2, you will lose your previous configuration, however, and you will have to use the NAM GUI to restore your configuration.
Before You Begin
Before you begin the upgrade process, we recommend that you perform a complete backup of your current NAM configuration. Doing so will record your current configuration which will be helpful if you have difficulties duplicating your previous configuration after the software upgrade.
To back up your current configuration, from the NAM command line, enter a config upload command like the following:
config upload ftp://server/path
The config upload command sends a copy of the NAM running configuration to the destination you specify. The information is stored in a back-up configuration file with an ending suffix of .confg as in NAM_host-c6svc-nam-3.6.1b.confg. The destination address should be a valid server name and directory path.
NAM does not support the upgrade from version 3.6 or lower to 4.2. If you try to upgrade from NAM 3.6 to NAM 4.2, due to the new architecture, the settings for alarms, reports, and capture files will not be upgraded to NAM 4.2. We highly recommend that you record these configurations in a final database backup so you maintain an archive of your final configuration before your software upgrade using the config upload command.
Table 10 provides information about configurations you might have issues with following your upgrade.
Table 10 Configurations To Restore After Software Upgrade to NAM 4.2
Configuration is not carried over in NAM 4.2. See Alarm Settings for more information.
Capture File Settings are carried over in NAM 4.2, but you will lose active captures that are configured as Capture to Buffer. To save current data, click Save to File or the current data will be lost. See Capture File Settings for more information.
Report configuration is carried over in NAM 4.2, and all reports will work properly except for those configured to gather data about the ALL SPAN data source on NAM-1 and NAM-1-250S devices. This data source is renamed DATA PORT in NAM 4.2.
Settings for voice monitoring and RTP stream monitoring will be disabled when NAM is upgraded to NAM 4.2. See Voice and RTP Monitoring for more information.
Configuration is set to default values and will need to be reconfigured using the NAM GUI. See Application Response Time for more information.
Alarm Settings
Due to changes in the NAM configuration file, alarms settings will not be carried over during the NAM 4.2 software upgrade. When you have completed the upgrade, go to the Setup > Alarms window and configure your desired alarm settings. We recommend that you record your settings for alarms before you begin the software upgrade to NAM 4.2.
Capture File Settings
Capture files will be retained after you upgrade to NAM 4.2, but you will lose active data still in memory for those captures configured as Save to Buffer.
Click Save to File to save current capture data in a file on disk.
Reports
Reports you have configured in NAM 3.6 will be carried over after you upgrade to NAM 4.2 and all reports will work properly except for those configured for the ALL SPAN data source on NAM-1 and NAM-1-250S devices. This data source is renamed in NAM 4.2 as the DATA PORT data source. After you upgrade to NAM 4.2, you need to recreate any reports set up for the ALL SPAN data source to use the DATA PORT data source instead.
Voice and RTP Monitoring
Settings for voice monitoring and RTP stream monitoring will be disabled when NAM is upgraded to NAM 4.2 due to architectural changes. We recommend that you record your settings for voice monitoring and RTP monitoring before you begin the software upgrade to NAM 4.2.
Application Response Time
The configuration you set up for application response time (ART) at the Setup > Monitor > Response Time > Configuration window will be set to the default values after you complete the software upgrade to NAM 4.2. If you have changed the settings on the Configuration window from their default settings, record those changes so you can restore the settings after the software upgrade.
Upgrading NAM Software
If you are upgrading a NAM-1 or a NAM-2 module, follow the software upgrade procedures described in the chapter Administering the Network Analysis Module in the following documents:
•
•
If you are upgrading an NME-NAM, follow the software upgrade procedures described in the section Upgrading the NAM Software-Full Image of the Cisco Branch Router Series (NME-NAM) Installation and Configuration Note.
If you are upgrading a Cisco NAM 2220 or Cisco NAM 2204 appliance, follow the procedures described in the chapter "Upgrading NAM Software" in the Installation and Configuration Guide for the Cisco NAM 2220 Appliance or "Upgrading NAM Software" in the Installation and Configuration Guide for the Cisco NAM 2204 Appliance.

On the Nexus 1000V NAM Virtual Service Blade, NetFlow record-related CLIs will send NetFlow record types below, which can be decoded properly by NAM. If you define your own record, it may not be decoded by NAM. This pre-defined collection of records offered by this CLI will work for most customers. Under "flow monitor" section as below
flow monitor YourMonitorNamerecord netflow-originalrecord netflow-original" will send NetFlow records that can be decoded properly by NAM.
MIB Limitation
Due to a Nexus 1010 Virtual Services Appliance MIB limitation, NAM Release 4.2 can't display the following information when "Managed Device" is VSM:
•
•
ACS Version Supported
The only ACS server version supported is 4.2.
Direct Flow Packets to NAM Data Port
If you use a NAM-2 device, either WS-SVC-NAM-2 or WS-SVC-NAM-2-250S, we recommend that you direct all packets for the same flow to the same data port.
Note
NAM-2 devices have two data ports (DATA_PORT1 and DATA_PORT2), but the packets received on these two ports are not well merged in respect to the order in which the packets are received. When packets for a given flow are split into two data ports, it might impact the calculation of application response time (ART) metrics and voice quality metrics.
No Default CLI Password
For security purposes, beginning with NAM 4.1, we no longer provide a default root password. After you upgrade the NAM software to NAM 4.2, you must specify a password for the root account. Store this password in accordance with your site's security policies. You will need the root account password for additional software upgrades.
Intelligent Application Performance and Voice Quality Analytics
The calculation of IAP and voice quality metrics in NAM 4.2 depends on the actual packet arrival time and packet sequences. In events such as packet drops, duplicated packets, or asymmetric routing, the NAM might not be able to calculate accurate quality metrics for the associated polling interval.
You should pay attention to the NAM syslog messages and system alerts to remain aware of any packet drops or duplicated packets occurrences.
Intelligent Application Performance
Due to the way NAM 4.2 processes packets in a TCP connection, response time monitoring on WAAS data sources probably will not include the first response of the TCP connection. This occurs because the WAAS optimization engine might not be able to determine to which optimized or non-optimized segment the first few packets belong.
This issue will be noticed when you monitor a TCP connection that has only a single response. No response time will be reported for this connection. The NAM determines response time by taking the average response time over multiple TCP connections. Because most TCP connections have multiple responses, this issue is generally unnoticed over a longer period of monitoring.
Analyzing Direct RTP Streams and Voice Traffic
To successfully build the association between the active phone list and RTP streams, you should direct both voice traffic (the control plane) and related RTP streams (the data plane) to NAM data ports. The data port number is insignificant because the NAM analyzes voice quality based on the ALL SPAN data source.
Checking the NAM Maintenance Image and BIOS Versions
NAM 4.2 software requires that you use the correct NAM maintenance image and BIOS versions. The recommended BIOS version for NAM 4.2 software is BIOS 6.0.9.
The recommended MP version depends on the NAM model. See Table 9 for the recommended maintenance image for each NAM platform. If you need to upgrade your NAM maintenance image, see Upgrading Catalyst 6500 and Cisco 7600 NAM-1 and NAM-2 Maintenance Image Software.
NAM Appliance Support for Cisco Nexus 7000
With the deployment flexibility the new Cisco NAM 2200 Series appliances offer, you now have a NAM solution to gain visibility into network and application performance for the Cisco Nexus 7000 Series switches. The Cisco NAM 2200 Series appliances provide core NAM functionality to support the Cisco Nexus 7000 Series including monitoring, reporting, capturing data and alarms. The NAM appliances support features such as traffic analysis, Intelligent Application Performance (IAP) monitoring, differentiated services analysis, and voice quality monitoring. The same NAM software image supports all tested infrastructure devices.
The Cisco NAM 2200 Series appliances do not yet offer the same level of management interface support they offer other tested devices, such as the Catalyst 6500 Series switches. This affects the following NAM functions:
•
•
•
Support for both NBAR-PD and MPLS functionality is not available for the Nexus 7000.
Restrictions for NME-NAMs
Note
The NAM Traffic Analyzer (web GUI) provides Layer 3 and higher layer information about the original packets. The Layer 2 header is modified by the router when it forwards the packets to the NAM, so the Layer 2 information that the NAM records is not applicable to the original packets.
IOS Issues That Might Affect NAM 4.2
The following IOS issues might affect your use of NAM 4.2 depending on other software versions.
•
•
•
•
IOS Image Incompatibility Prevents Creating SPAN Data Sources Using NAM GUI
An issue with the supervisor card and IOS images 12.2(18)SXF9 and 12.2(33)SRB1 prevents you from creating SPAN data sources (SPAN sessions) using the NAM GUI. (This issue is described in CSCse98807.)
Note
You can also use switch command-line interface (CLI) commands to create SPAN sessions, or you can use other IOS releases on the supervisor card, such as 12.2(18)SXF10 or 12.2(33)SRB2, that fix this IOS issue.
On affected systems, when you attempt to use the NAM GUI to create a SPAN session by choosing
Setup > Data Source and clicking Create, the NAM GUI displays no information for the Destination Port. This prevents you from creating the SPAN session.Cisco 7600 With Redundant Supervisor Cards Running IOS Image 12.2(33)SRC2
You might experience an error condition with a Cisco 7600 chassis that has redundant supervisor cards running the 12.2(33)SRC2 IOS image and a NAM service blade. The error occurs when you perform a sequential boot of the two supervisor cards because the secondary (standby) supervisor does not go into proper standby mode.
You can find more information about this issue in Field Notice #63179.
Note
This problem does not occur:
•
•
•
•
Problem Symptom
When the primary supervisor functions as a standalone with the secondary supervisor card in RPR mode, the Cisco 7600 chassis functions normally (as if it has a standalone supervisor card). A switchover causes the system to be unavailable for up to three minutes because the secondary supervisor card is not in proper standby mode.
Note
Solution
This problem requires you to downgrade the IOS image from 12.2SRC2 to 12.2SRC1. Account teams will help you do this if needed.
Running IOS Image Newer Than 12.2(18)SXF5
If you upgrade your IOS to an image newer than 12.2(18)SXF5, you remain vulnerable to a security issue where IOS switches the SNMP communication between the NAM and the SUP from inband to EOBC.
Due to this issue, you should not apply the NAM CLI command supervisor address <sup-address>. To remove this configuration from the NAM, use the negating form of the command,
no supervisor address.
Note
RSPAN and ERSPAN Unsupported in IOS Image 12.2(33)SRD
The ERSPAN command is not working properly in NAM 4.2 when using IOS image 12.2(33)SRD. The problem is noticed when you attempt to configure a destination on the NAM in ERSPAN or RSPAN sub-mode.
After issuing the command:
destination analysis-module 3 data-port 1
Where module 3 is the NAM you have set up to monitor (using the command monitor session 1 type erspan-destination), the configured destination cannot be found.
This problem also affects the local SPAN (with sub-mode configuration).
