Intelligent Application Performance
The Intelligent Application Performance (IAP) feature helps you gain a better understanding of your applications' performance and enables you to do the following:
•
•
•
•
The IAP feature helps you see how well the network is delivering services to the end user, providing an overall view of what is happening on the network. It monitors the TCP application packets as they travel from the client through the network to the data center and out again, measuring network round trip time, client response time, and server response time.
NAM 4.0(1a) calculates additional metrics to help you ensure the efficient and effective delivery of applications and services in your network. The following lists some of the new metrics:
•
•
•

4.0-Rel 6.0.9 or later
WS-SVC-NAM-2
Before upgrading WS-SVC-NAM-1 or WS-SVC-NAM-2 from NAM 3.6 release to NAM 4.0(1a), 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 4.0(1a) without upgrading the BIOS image. If it is not, the BIOS image must be upgraded. If the BIOS is not upgraded before installing NAM 4.0(1a), NAM 4.0(1a) 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.

Supported Upgrades
NAM 4.0(1a) supports upgrades from the NAM 3.5 and NAM 3.6 software releases (with any patches) on the following NAM devices:
•
•
•
•
•
•
•
Also, NAM 4.0(1a) supports upgrades from the NAM 4.01 software releases on the following NAM devices:
•
•
•
•
•
•
•
•
•
•
NAM 4.0(1a) does not support upgrades from NAM 3.4 or below. However you can reinstall NAM 4.0(1a). See the next section, Reinstalling NAM Software.
Reinstalling NAM Software
Although you cannot upgrade from a version prior to NAM 3.4, you can do a reinstallation 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 reinstall software with NAM 4.0(1a), 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 4.0(1a) has a new architecture that will cause you to lose some of the configuration you have currently set in your NAM. When you upgrade from NAM 3.6 or NAM 3.5 to NAM 4.0(1a), due to the new architecture, the settings for alarms, reports, and capture files will not be upgraded to NAM 4.0(1a). 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 9 provides information about configurations you might have issues with following your upgrade.
Note
Table 9 Configurations in Jeopardy After Software Upgrade to NAM 4.0(1a)
Configuration is not carried over in NAM 4.0(1a). See Alarm Settings for more information.
Capture File Settings are carried over in NAM 4.0(1a), 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 4.0(1a), 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 4.0(1a).
Settings for voice monitoring and RTP stream monitoring will be disabled when NAM is upgraded to NAM 4.0(1a). 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 4.0(1a) 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 4.0(1a).
Capture File Settings
Capture files will be retained after you upgrade to NAM 4.0(1a), 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 4.0(1a) 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 4.0(1a) as the DATA PORT data source. After you upgrade to NAM 4.0(1a), 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 4.0(1a) 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 4.0(1a).
Application Response Time
The configuration you set up for application response time (ART) at the Setup > Response Time > Configuration window will be set to the default values after you complete the software upgrade to NAM 4.0(1a). Use the information in the configuration file to reconfigure these settings.
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:

Limitations and Restrictions
The following limitations and restrictions currently apply to the NAM 4.0(1a) software release:
•
•
•
•
•
•
•
•
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 4.0(1a), we no longer provide a default root password. After you upgrade the NAM software to NAM 4.0(1a), 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 4.0(1a) depends on the actual packet arrival time and packet sequences. In events such as packet drops, duplicated packets, or asymmetric routing, the NAM may not be able to calculate accurate quality metrics for the associated polling interval.
Administrators should pay attention to the NAM syslog messages and system alerts to be aware of any packet drops or duplicated packets occurrences.
Intelligent Application Performance
Due to the way NAM 4.0(1a) 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 4.0(1a) software requires that you use the correct NAM maintenance image and BIOS versions. The recommended BIOS version for NAM 4.0(1a) software is BIOS 6.0.9.
The recommended MP version depends on the NAM model. See Table 8 for the recommended maintenance image for each NAM platform. If you need to upgrade your NAM maintenance image, see Upgrading the NAM 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 NM-NAM and 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 Affecting NAM 4.0(1a)
The following IOS issues affect the use of NAM 4.0(1a):
•
•
•
•
•
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.) This issue has been resolved with IOS image 12.2(18)SXF10.
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.
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.
This problem will be fixed in 12.2(33)SRC4; a target date for this release is not yet available.
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.RSPAN and ERSPAN Unsupported in IOS Image 12.2(33)SRD
The ERSPAN command is not working properly in NAM 4.0(1a) 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).
Wrong Egress Interface Found in 12.4(20)T and 12.4(22)T
This issue is described in caveat CSCsr18741. This issue affect NME-NAMs using image 12.4(20)T and 12.4(22)T.
This issue will be noticed when you attempt to use the NME-NAM to monitor interface-based traffic using CEF support.
A change to correct this issue is expected in 12.4(23.7)T.
