Step 8 Plug in the power cable on the rear of the appliance. See location number 8 in Figure 1.

Step 9 Power on the appliance. Make sure you do not turn on the power until you have completed all cable connections for the Cisco NGA.

See location 8 in Figure 2 for the location of the Power button. Power status LED corresponds to the following states:

• Off—No AC power is present.
• Green, blinking—The appliance is in standby power mode.
• Green—The appliance is in main power mode.

For additional front panel LED status descriptions, see Front-Panel LEDs.

After you turn power on and boot Cisco NGA for the first time, the login prompt displays on the attached console.

Step 10 Log into appliance. Use root as user and root as password.

The system prompts you to change the password. When shipped from the factory, the root user is preconfigured on Cisco NGA. The default password for the root user is root. The root user has privileged access to the root (read/write) level of Cisco NGA and can enter command-line interface (CLI) commands.

Note We require you to change the user root password during the first login session. Use a password that contains at least eight characters and contains numbers, uppercase and lowercase letters, and symbols.

Step 11 Enter the following information using the ip CLI command:

• Cisco NetFlow Generation Appliance’s management address.
• The subnet mask.
• The default gateway IP address.
• (Optional) The primary DNS server IP address.

Step 12 Enter show ip to verify that you entered the correct network settings.

Step 13 (Required for GUI users) Enter ip http server enable to create the web user account. To enable the HTTPS secure web server, enter ip http secure server enable.

The web server requires at least one properly-configured web administrator. If the appliance does not prompt you for a web username and password, then at least one web administrator was previously configured.

---

Note Cisco NetFlow Generation Appliance supports only one web user account.

Enter the username of the web administrator. Press Enter to use the default web administrator username admin.

Enter a password for the web administrator, then reenter the same password again to ensure accuracy.

Step 14 Load the user interface for Cisco NetFlow Generation Appliance in a web browser, for example, enter http://<NetFlow_Generation_Appliance_management_address>. You can use the fully-qualified domain name that you configured in Step 11 for the appliance name or Cisco NGA IP address.

Step 15 Log into Cisco NetFlow Generation Appliance by entering the username and password entered in Step 13.

Step 16 Verify that traffic is being replicated to the appliance. To verify replication, enter:

show dataport statistics cumulative

show dataport statistics rates

Step 17 Set the time and time zone settings by selecting Administration > System > System Time. Optionally, you can perform this task from the CLI. The appliance will restart some processes.

Step 18 Set the SNMP Agent community string and system information by selecting Administration > System > SNMP Agent.

Step 19 Continue to Configure Your Appliance to Export NetFlow V5 or V9 Records to complete the quick start setup.

 

Configure Your Appliance to Export NetFlow V5 or V9 Records

This section describes how to quickly configure a single NetFlow monitor instance (monitor, exporter, and collector) on one instead of multiple web pages using the Quick Setup graphical user interface (GUI).

The Advanced Setup GUI allows you to configure multiple NetFlow monitor instances in separate windows. You can also configure filters that will limit the amount of traffic from the Cisco NetFlow Generation Appliance to the collectors you designate from the Advanced Setup GUI. To configure IPv6 or Layer2 records, you must use the Advanced Setup tab or the CLI. This guide covers only quick setup details. To complete any of the configuration scenarios described above, see the Cisco NetFlow Generation Appliance User Guide.

In more diverged network traffic environments, Cisco NetFlow Generation Appliance is capable of processing and generating NetFlow records for a mixture of IPv4 and IPv6 traffic.

NetFlow v5 supports only IPv4. V9 is template-based and is used to report flows like IPv6, MPLS, or IPv4.

This configuration enables Cisco NGA to monitor the data ports and export v5 or v9 NetFlow records of either IPv4, IPv6, or both flow data to a specified collector.

Follow the procedure below and use the online help if you need additional details. You can also use CLI commands to configure the appliance.

To configure your appliance to export NetFlow traffic:

Procedure

---

Step 1 To complete a quick setup (which consists of one monitor, exporter, and collector), choose Setup > NetFlow > Quick Setup.

Step 2 Enter the required data.

For v9 records, select your desired match and collect fields in the Quick Setup pane. This allows you to configure flow records for IPv4 only. IPv6 record is available in the Advanced Setup only. See online help for details.

If you have a more advanced requirements, for example, you need to configure IPv6 records, you must manually add the components using the Advanced Setup window. See the Cisco NetFlow Generation Appliance User Guide for complete details on this configuration.

Step 3 Click Submit.

The Monitor tab appears displaying the newly added name_monitor.

Step 4 To activate the flow monitor, choose the monitor you created in the Monitor tab and click Activate/Inactivate. This enables the flow monitor to generate NetFlow information to the collector.

Step 5 Continue to Verify Flow Records Generated to ensure records reach their destination.

 

Verify Flow Records Generated

To verify flow records have reached their destination, check the collector data by entering both of the following commands:

• show cache statistics rates monitor_name command. Counters begin to increment only after a minute has passed. This command displays the rate of raw traffic being processed and the number of flows being created and forwarded to the exporter engine.
• show collector statistics collector_name command. This displays the information about NetFlow packets being sent to the collector.

After you verify that the collector has received the flow record data, you have completed the quick start configuration. To configure additional monitor instances, repeat the quick start configuration or review the steps in the User Guide on how to configure multiple monitor instances using the Advanced Setup.

How to Shut Down and Start Up Cisco NGA

If you must shut down the Cisco NetFlow Generation Appliance for maintenance purposes, use the shutdown command in the CLI.

Do not use the Cisco NGA Power button unless the shutdown command is unsuccessful. Remember to disconnect the power cords from the power supply to completely power off the appliance.

Install SFP+ Modules

This section describes how to install or replace your SFP+ modules:

• SFP+ Module Overview
• Install an SFP+
• Replace an SFP+

SFP+ Module Overview

The Cisco NetFlow Generation Appliance uses up to four 10 Gigabit Ethernet small form-factor pluggable modules (Cisco 10GBASE SFP+ modules) to connect fiber optical cables as data input sources. You can install any combination of long-range and short-range SFP+ modules. Depending on the type of SFP+ you use, you must use the correct fiber optical cables. The SFP of the interface at the monitored device must be the same type as the monitoring port you connect to on the Cisco NGA.

You can order SFP+ as hardware options or you can use SFPs you might already own as long as they meet the specifications described in the Cisco 10GBASE SFP+ Modules Data Sheet Because SFPs are delicate devices, they are packaged separately and are not installed in the appliance prior to shipping. The Cisco NGA supports both the short range and long range Cisco standard SFP+ (10G SFP).

You install the SFP+ modules into slots on the rear panel of the Cisco NGA. Make sure you review the slot locations for data ports 1 through 4 as they are not numbered logically (see Figure 3). Figure 5 shows a detailed view of an SFP+ module installation.

Figure 5 Installing an SFP+ Module

 

 

The SFP+ module uses the bail clasp latching mechanism as shown unlatched in Figure 6 and latched in Figure 7. See the label on the SFP+ for technology type and model.

SFP+ dimensions are:

• Height 0.33 inches (8.5 mm)
• Width 0.72 inches (18.3 mm)
• Depth 3.1 inches (78 mm)

SFP+ temperature ranges are:

• COM—Commercial operating temperature range between 23 degrees Fahrenheit to 158 degrees Fahrenheit (-5 degrees Celsius to 70 degrees Celsius)
• EXT—Extended operating temperature range between 23 degrees Fahrenheit it to 185 degrees Fahrenheit (-5 degrees Celsius to 85 degrees Celsius)
• IND—Industrial operating temperature range between -40 degrees Fahrenheit to 185 degrees Fahrenheit (-40 degrees Celsius to 85 degrees Celsius)

Backing Up Your Configuration

Before you begin the upgrade process, we recommend that you perform a complete backup of your current NGA configuration.

---

Note Having a backup configuration file can save you time and frustration if your NGA appliance should suffer a hard disk failure that requires you to reformat or repartition your hard disk drives. This procedure does not back up the capture files and the monitoring data.

To back up your current configuration, use the NGA CLI config upload command like the following:

config upload ftp:// user:password@server//path backup_file_name

For example:

config upload ftp:// admin:secret@172.20.104.11/archive/nga_config

In NGA 3340, besides ftp, secure transfer protocol such as sftp, scp and https is also supported. You can run config upload ? to get the latest help info and example.

The config upload command sends a copy of the NGA running configuration to the destination you specify. The copy of your configuration is stored in a back-up configuration file with an ending suffix of .config as in NGA_host-nga-1.1-1.config. The destination address should be a valid server name and directory path where you have read and write permissions.

Restoring Your Configuration

If you have stored your NGA configuration file at a remote server location that you can access using FTP or HTTP (see Backing Up Your Configuration), you can restore your NGA configuration file after a system recovery or upgrade. This, however, is optional.

Use the config network command to restore your previous NGA configuration, as in the following:

config network ftp:// user:password@server//path backup_file_name

For example:

config network ftp:// admin:secret@172.20.104.11/archive/nga_config/NGA_host-nga-1.1-1.config or NGA_host-nga-1.1.1.ngaconf.tar

In NGA 3340, besides ftp, secure transfer protocol such as sftp, scp and https is also supported. You can run config upload ? to get the latest help info and example.

Upgrading Your Software

To upgrade the software for a Cisco NetFlow Generation Appliance:

---

Step 1 Download the NGA application software for the Cisco NetFlow Generation Appliance from the Cisco.com at the following URL:

http://www.cisco.com/cgi-bin/tablebuild.pl/nam-appl

Step 2 Look for a file that begins with nfa-app, as in nfa-app-x86_64.x-x-x.bin.gz (where x-x-x is the NGA software release number). The file will be described as the NGA Application Image.

Step 3 Store the NGA application software on the same server where you archived your NGA configuration.

Step 4 Use the commands as needed from the list of upgrade commands shown in Table 1-7 .

 

2.You may also use HTTP instead of FTP.

 

Recovery Installation

You can use the helper utility to reinstall NGA application software on your Cisco NetFlow Generation Appliance if your appliance should suffer a catastrophic event, such as a hard disk crash, and you can no longer boot the NGA application.

To access the helper utility, use the Cisco Image Management Controller (the CIMC, not the NGA management port) to map the NGA recovery ISO file to the virtual media CD.

---

Note You must log in with user or admin privileges to perform this task.

---

Step 1 Download the ISO file from CCO (where all of the other NGA images are).

Option n - Configure Network

Use Option n to configure the network parameters for the appliance.

---

Step 1 When the Configure Network Interface menu displays, enter 2 to configure manually.

Step 2 The utility prompts you for the IP address, netmask, and default gateway for the appliance.

Step 3 Check your network configuration using Configure Network menu option 3.

 

Option 1 - Download Application Image and Write to HDD

Prior to using Option 1, first use Option n to configure the network.

Use Option 1 to download a version of the application image from an FTP server location and write the image to the hard disk drive. This option requires network connectivity and that network parameters be configured for the appliance using helper menu item n.

This option enables you to download an image you might have stored at an FTP location or at a location you can access using http. You can download the latest version of software from the following URL:

http://www.cisco.com/cgi-bin/tablebuild.pl/nga-appl

This URL requires you to have a Cisco service agreement and access to the internet to download the zipped software.

Option 2 - Download Application Image and Reformat HDD

Prior to using Option 2, first use Option n to configure the network.

Use Option 2 to download the application image and write the image to the hard disk drive. This option downloads a version of the application image from an FTP server location or at a location you can access using http.

Using this option reformats the hard disk drives before writing the application image and will destroy all data such as reports or data captures.

You can also download the latest version from Cisco.com.

Option 3 - Display Software Versions

Use Option 3 to display the current application image version stored on your hard disk.

Option 4 - Reset Application Image CLI Passwords to Default

Use Option 4 to reset the password for users root and admin to their default values.

Option 5- Send Ping

Use Option 5 to send a ping to determine if network connectivity exists. When prompted, enter the IP address or full domain name of the location to send the ping.

Option 6- Display RAID Settings

Use Option 6 to display the current RAID settings.

Option r- Exit and Reset Services Engine

Use Option r to reset the appliance prior to rebooting the newly installed application image.

Before using Option r, remove the recovery CD from the CD drive to enable the appliance to boot the application image.

Option h- Exit and Shutdown Services Engine

Use Option h to reset and shut down the appliance.

Setting up Serial Console Connection

There are two ways to connect to the NGA serial console:

• Serial over LAN (SoL)–Allows access to the NGA serial console through the web-based GUI or SSH-based CLI of CIMC. This access method is configured by default.
• Physical external serial console connector (RJ-45)–Allows access to the NGA serial console through a direct serial cable or terminal server. See section Setting up Serial Console Access through External RJ-45 Port for details.

NGA supports two serial console ports: com0 and com1. The NGA CLI can be accessed through either of these ports. However, only the com0 port provides full output and interactivity during the bootup process. The two serial console options (SoL or RJ-45 connector) cannot use com0 at the same time, so you should assign com0 to the option you would customarily use within your environment. By default, the NGA is configured with SoL on com0, so if SoL is your preferred method of access, then you need not do anything more. If you prefer to assign com0 to the RJ-45 serial port, then follow the steps in section Setting up Serial Console Access through External RJ-45 Port.

Setting up Serial Console Access through External RJ-45 Port

See Figure 1 for Serial connector (RJ-45) location.

To setup serial console access through the external RJ-45 port:

---

Step 1 Log into the CIMC GUI.

Step 2 Click the Server tab and then click Remote Presence.

Step 3 Click the Serial over LAN tab.

Step 4 If you do not want to use Serial over LAN, uncheck the Enabled check box. This will make the serial console accessible on com0 through the RJ-45 port. Alternatively, if you prefer to use the RJ-45 serial console primarily, but maintain Serial over LAN as a secondary method for access to the NGA CLI, then keep Serial over LAN enabled, but change Com Port to com1.

Step 5 Click the Save Changes button.

Console access through the RJ-45 console port will be enabled. Configure your terminal emulator or terminal server to use 9600 baud/bps, 8-N-1 when connecting to the console.

In some cases, it may be necessary to power cycle the NGA before the serial console works. From the CIMC GUI, click the Server tab and click Summary, and then click Power Cycle Server.

 

Troubleshooting Overview

Before and at initial system boot, you should verify the following:

• External power cable is connected, and the proper power source is being applied.
• The appliance fan and blower are operating.
• The appliance software boots successfully.
• The adapter cards (if installed) are properly installed in their slots, and each initializes (is enabled by the appliance software) without problems.

When each of these conditions is met, the hardware installation is complete, and you should proceed to perform a basic configuration (see the software installation guide or user guide that supports your appliance for proper configuration procedures).

If you cannot locate the source of the problem, contact a customer service representative for information on how to proceed. For technical support information, see the Cisco Information Packet publication that shipped with your appliance. Before you call, have the following information ready:

• Appliance chassis type and serial number
• Maintenance agreement or warranty information (see the Cisco Information Packet)
• Type of software and version number (if applicable)
• Date you received the new appliance
• Brief description of the problem you are having and the steps you have taken to isolate and resolve the problem

---

Note Ensure you provide the customer service representative with any upgrade or maintenance information that was performed on the Cisco NetFlow Generation Appliance after your initial installation. We recommend you create a site log that contains a description of the actions performed on your appliance as well as the date and responsible user.

Problem Solving

The key to problem solving is to isolate the problem to a specific location by comparing what the Cisco NetFlow Generation Appliance is doing to what it should be doing.

In other words, when troubleshooting, define the specific symptoms, identify all potential problems that could be causing the symptoms, and then systematically eliminate each potential problem (from most likely to least likely) until the symptoms disappear.

---

Note The LEDs on the front panel of the appliance enable you to determine appliance performance and operation. For a description of these LEDs, see the “Read the LEDs” section.

When problem solving, check the following appliance subsystems first:

• Power and cooling systems—External power source, AC power cable or DC power wires, and appliance fans. Also check for inadequate ventilation, air circulation, or environmental conditions.
• Adapter cards—Checking the LEDs on the adapter card can help you to identify a failure.
• Cables—Ensure that the external cables connecting the appliance to the network are all secure.

Table 8 provides troubleshooting tips for possible appliance subsystem problems.

 

Read the LEDs

This section describes the following Cisco NetFlow Generation Appliance LEDs:

• Front-Panel LEDs
• Rear-Panel LEDs
• Built-In NIC LEDs

The LEDs serve the following purposes:

• Indicate that basic power is available to the appliance
• Guide you to a broken adapter card, or to one that has failed its diagnostics
• Give an indication that traffic is flowing through the adapter card to the appliance

The LEDs on the front and rear panels of the Cisco NetFlow Generation Appliance and corresponding adapter card are aids for determining appliance and adapter performance and operation.

Front-Panel LEDs

Table 9 describes these LEDs. See Figure 2 for the locations of the appliance front-panel LEDs.

 

Rear-Panel LEDs

Table 10 describes these LEDs. For read-panel LEDs, see Figure 1 or the UCS C220 Installation and Service Guide on Cisco.com.

 

Built-In NIC LEDs

Figure 8 shows the NIC 1 and NIC 2 LEDs located on the rear of the appliance. These LEDs indicate the connection activity and speed of the NIC ports. Table 11 describes the activity and connection speed associated with each LED state. The 10 Gb Ethernet link status LED and the speed LED must be read in combination for the following interpretations.

Figure 8 NIC 1 and NIC 2 LEDs
