Release Notes for Cisco Prime Network Analysis Module 6.0(2)

April 14, 2014

This document provides general information about Cisco Prime Network Analysis Module (Prime NAM) 6.0(2) software.

This document includes the following sections:

Introduction

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 intuitive workflows, contextual drill-downs, and one-click captures
  • Comprehensive traffic statistics, application response time metrics, and voice/video performance analytics
  • Detailed troubleshooting with continuous and triggered packet captures, advanced filters, and error scans
  • Enhanced packet-level visibility and advanced troubleshooting.

In addition to the features and functionalities detailed in New and Changed Features in Release 6.0(2), this release also supports two new platforms: Cisco Nexus 7000 Series Network Analysis Module (NAM-NX1) and Cisco Prime Virtual Network Analysis Module (vNAM) platform. Cisco Prime Virtual Network Analysis Module (Prime vNAM) can be installed on x86_64 platforms with ESXi and KVM virtualization infrastructures.

NAM-NX1

Cisco NAM-NX1 is the first service module for the Cisco Nexus 7000 Series switch.

See the NAM Compatibility Matrix for the supported 7000 Series devices.


Tip To take advantage of the Cisco Nexus 7000 Series Release 6.2(8) performance improvements for Data Center protocols (VxLAN, FabricPath,  OTV, LISP, Segment ID, VNTag, and FCoE), you can 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.


Prime vNAM

You can deploy Prime vNAM in the cloud to monitor hosted workloads, or wherever you want in the network to eliminate blind spots. It combines comprehensive application awareness, performance analytics, and network visibility, enabling the network administrators with actionable information to manage their networks.

All Platforms

New and Changed Features in Release 6.0(2)

This section contains:

provides a detailed list of new features and functions and enhancements to Release 6.0(2).

For Cisco Prime NAM features and benefits, see the data sheets for your specific platform, on Cisco.com .

 

Table 1 New and Changed Features in Prime NAM 6.0(2)

Feature
Description
See...section in User Guide

New Features

Rolling buffer capture option (Stop-save trigger)

When an event for which you have defined an alarm threshold occurs, Prime NAM stops any existing capture session and saves the captured packets from memory into a file. The capture session then restarts.

Understanding Trigger Capture

Scheduled capture

Scheduled capture provides a way to set up your capture session based on the date and time, as well as the duration desired.

Multiple capture sessions can be created for a single storage target.

However, there can only be one session running at a given time per storage target.

Capture trigger override priority

Capture trigger override priority provides a way to configure multiple capture sessions to use the same disk partition. Because only one session can be running, Prime NAM prioritizes capture sessions based on a set of rules.

Enhanced captured packet decode

Provides enhanced display decode UI.

Understanding the Packet Decoder

Advanced settings feature in the email settings page

Includes:

  • Ability to designate port used to email access server
  • Option to select an encryption protocol

Auto Logout

The server is polled every minute. If a good session is not found, the page will be refreshed after three attempts, taking you to the login page, and then back to the same page. In case of popup windows the window is just closed.

Support for IPv6

The release delivers USGv6 certification for all NAM form factors.

Ability to validate nameserver

New button on Administration > System > Network Parameters to validate name servers.

Interface Statistics Aggregation Interval

Managed Device Interface Stats in Setup Aggregation Interval page allows you to configure how the Prime NAM receives SNMP interface statistics over longer intervals. The interval is 1 minute (default), 5 or 10 minutes. The long-term interval is 60 minutes (default) or 120. If visibility to Prime NAM managed device's interface stats is not desired, this feature can be disabled.

Encapsulation Dashboard

TopN Encapsulations chart replaces TopN VLAN chart on Monitor > Overview > Traffic Summary.

Allows you to drill-down into sub-encapsulations and see overtime traffic, sub-encapsulations, applications, hosts and DSCP Aggregation (for the filters).

The Setup > Classification > Encapsulations page is removed.

Using Traffic Summary

Graphic scheduled report

Changed Features

Prime NAM should be operated within the specified capabilities. Excessive traffic load, excessive configurations like very high number of alarms and concurrent capture sessions, decoding very large capture files, and excessive disk usages, may cause the Prime NAM system to slow down and GUI to be less responsive.

Prime NAM running on different physical hosts, different hypervisors, and different hardware virtualization support may have different performance levels.

Do not run ERSPAN capture if you are monitoring more than 7 Gb traffic (NAM-3

SPAN creation screen doesn't allow selection of ports on FEX modules

Prime NAM Data Sources UI changes

  • PA & WAAS data source segments are shown in individual rows instead of a single row.
  • To delete segments, select them from the list and click Delete .
  • To create or auto create segments, choose the respective button on the page.
  • You can rename a particular data source segment for Edit option.
  • Data Source Details column shows segment information, in case data source name is changed.

Host conversations webpage changes

Host conversations will not show Conversations From and Conversations To tables. Instead only one table, Conversations for host, is displayed.

Earlier, two tables were displayed.

Changes to clear monitoring-data command

This command no longer reboots Prime NAM, it only restarts the processes. The CDB allocation speed has been improved.

Changes to config clear command.

This command no longer modifies the CDB files. It only removes config, as the command name suggests.

VLAN parameter is not supported in site rule

Site definitions that are supported in Prime NAM 6.0(2) are:

  • Subnet network
  • Subnet network and Prime NAM data source.
  • NDE data source
  • WAAS data source

Configuring Sites

UI improvements and changes

  • Histograms added to ART dashboards.
  • Tables, bar charts, line charts, and pie charts—Includes more details in tooltips and labels, and fixes to known issues.
  • Response Time setup page modify to enable you to understand what you are configuring.
  • Removed Setup > Encapsulation page.
  • Removed Setup > Data Export > NetFlow Capture > Packet Capture/Decode > Display Filters pages.
  • Response Time Distribution chart on ART related pages.

Changed the capture file format for Appliances from native format to .pcap format.

ENC format is deprecated.

Downloading capture files in ENC format is not recommended.

Changes to application response time (ART) unit display.

If all chart data is in a single time unit range (that is, all in milliseconds or all in microseconds or all in seconds), then that time unit is displayed.

Otherwise, milliseconds is the default unit, and all data is normalized to milliseconds.

Table data is shown in microseconds.

Changed SPAN sessions UI page for Nexus 7000. Change is applicable to NAM appliance and NAM-NX1.

For the NAM appliance, the new page is visible:

1. netconf command is enabled.

2. The netconf address, username, and password for the device are provided.

3. It is either a Nexus 7000 or Nexus 5000.

For NAM-NX1, Device Information page is changed.

Very small data values may be rounded down to zero (3 decimal precision).

NAM no longer receives PA data from UDP port 3100

Prior to NAM 6.x release, NAM NetFlow is receiving from UDP port 3000, and NAM PA is receiving from UDP port 3100. As the result, existing PA device configuration has to be modified to UDP port 3000.
