Cisco Prime Network Analysis Module Software 5.0(1T) Release Notes
June 15, 2011, OL-24432-01
These release notes describe how to use the Cisco Prime Network Analysis Module 5.0(1T) software with the Cisco Catalyst 6500 Series Network Analysis Module (NAM-3). It includes new features and enhancements, system requirements, software upgrade, limitations and restrictions, caveats, and links to product documentation.
The Cisco Prime Network Analysis Module software empowers Network Managers with actionable visibility to quickly troubleshoot performance issues, ensure optimal use of network resources, and deliver consistent end-user experience.
The Cisco Prime portfolio of enterprise and service provider management offerings supports integrated lifecycle management of Cisco architectures and technologies based on a service-centric framework. Built on an intuitive workflow-oriented user experience, Cisco Prime products help increase IT productivity and reduce operations costs through innovative management solutions for the network services, infrastructure, and endpoints.
Network administrators need multifaceted visibility into the network and application to help ensure consistent and cost-effective delivery of service to end users. Knowing how traffic over the network is being used and how it is performing is essential for managing and improving the delivery of your business-critical applications. It is the foundation for establishing and verifying quality of service (QoS) policies, undertaking WAN-optimization projects, and rolling out voice over IP (VoIP). It is also the foundation for recognizing when a configuration change has unintentionally degraded application performance or for providing proof points that it is the application and not the network that is causing one of your business planning systems to perform poorly, so that the appropriate actions can then be taken.
This document includes the following sections:

Data Storage Recommendation
The Cisco Catalyst 6500 Series Network Analysis Module (WS-SVC-NAM3-6G-K9) offers external storage connectivity for extended capture durations and higher capture bandwidths. This connectivity is provided through two front-panel ports, one Mini Serial Attached SCSI (SAS, SFF-8088), and one Fibre Channel Over Ethernet (FCoE, SFP+). The external SAS storage array can be directly attached, while most FCoE arrays require an FCoE-capable switch (such as the Nexus 5000 Series Switch) to connect to a NAM-3. A Nexus 5000 Series Switch can connect to multiple FC and FCoE storage arrays.
If you are using FCoE storage, Cisco recommends that your Nexus 5000 Series Switch is running NX-OS 5.0(3)N1(1) or higher.

Upgrading to NAM 5.0(1T)
This section provides the following topics:
The NAM 5.0(1T) software does not support any upgrade paths from any other NAM 3.x, NAM 4.x, or NAM 5.x releases. NAM 5.0(1T) is the first release of NAM that runs on the high performance Cisco Catalyst 6500 Series Network Analysis Module (WS-SVC-NAM3-6G-K9), and the NAM 5.0(1T) release only runs on this platform.
Installing NAM Software
For installation information, see the Cisco Prime Network Analysis Module (NAM-3)
Catalyst 6500 Series Switch Installation and Configuration Note 5.0(1T), which is available on Cisco.com:
Cisco router ROM monitor (also known as ROMMON) runs when the router is powered up or reset. The firmware helps to initialize the processor hardware and boot the operating system software. You can perform certain configuration tasks, such as recovering a lost password or downloading software over the console port, by using the ROM monitor. If there is no Cisco IOS software image loaded on the router, the ROM monitor runs the router.
The BIOS and ROMMON images for the NAM-3 blade are bundled together, and are always installed in one process. To update the TriX86 Boot Firmware using the BIOS disk TFTP utility:
Step 1 Copy biosdisk_tri_x_y_z.bin to your TFTP server.
Step 2 Connect to the local TriX86 console.
Step 3 Break into TriX86 ROMMON if you are in an autoboot mode.
Step 4 Select the external ethernet interface port that is on your TFTP network (if not already the default port in ROMMON). This is done from the ROMMON CLI using the interface command.
Step 5 Set the ROMMON TFTP parameters:
•local port IP address: addr w.x.y.z
•server IP address: serv w.x.y.z
•gateway IP address if applicable: gate w.x.y.z
•file path on TFTP server: file userid/biosdisk_tri_x_y_z.bin
•NAM management VLAN: vlan x
Step 6 Verify the connection to the server with a ping, using either ping server or ping w.x.y.z.
Step 7 TFTP boot the BIOS disk utility using the command tftpdnld.
Step 8 The BIOS disk will automatically reprogram the boot SPI flash, and then stop at the BIOS disk CLI prompt. Enter reboot after the installation is complete to reset the NAM.
Limitations and Restrictions
The following limitations and restrictions currently apply to the NAM 5.0(1T) software release:
Data Storage (NFS and iSCSI)
In previous releases of NAM, you use the Administration > Capture Data Storage option to set up remote file systems to store capture data, and you could choose the type NFS or iSCSI. In the NAM 5.0(1T) release, you use the Capture > Packet Capture/Decode > Data Storage option to set up external data storage, and NFS and iSCSI storage are not supported.
NAM Support With Non-Cisco H.323 Voice Devices and Call Managers
NAM voice call monitoring may not function properly with some of the non-Cisco voice devices and Call Managers such as Avaya. This is only for non-Cisco voice devices. Cisco IP Phone and Call Managers do not have any problems.
ACS Version Supported
The only ACS server versions supported are ACS versions 5.1 and 4.2.
No Default CLI Password
For security purposes, beginning with NAM 4.1, we no longer provide a default root password. After you install NAM 5.0(1T), 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.
Response Time and Voice Quality Analytics
The calculation of Application Performance Response Time and voice quality metrics in NAM 5.0(1T) 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.
WAAS Intelligent Application Performance
Due to the way NAM 5.0(1T) 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.
Most Recent NAM 5.0(1T) Information
To see the most recent version of the NAM 5.0(1T) User Guide, see the technical documentation for the Cisco Prime Network Analysis Module on www.cisco.com:
IOS Issues That Might Affect NAM 5.0(1T)
The following IOS issues might affect your use of NAM 5.0(1T) depending on other software versions.
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 This issue has not yet been resolved.
