Installing NAM Hardware in a Cisco Nexus 7000 Device
If you purchased the Cisco Nexus 7000 switch with a Cisco NAM-NX1 service module, the Prime NAM software comes preinstalled and ready to use.
If you purchased the NAM separately, see the Cisco Nexus 7000 Series Hardware Installation and Reference Guide for instructions on how to install the hardware service module.
This section includes these topics:
NAM Module
The NAM service module plugs into a host Cisco switch running Cisco Nexus operating system (Nexus OS) software.
Cisco NAM-NX1 is a standalone module with its own startup and run-time configurations that is independent of the Cisco NX-OS configuration on the switch. The module does not have an external console port. Instead, you can launch and configure the module through the NAM management interface/port on the backplane or through the switch, with a configuration session on the module.
The NAM requires minimal configuration from the supervisor card in the switch. For detailed steps, see Configuring the NAM Software.
For instructions on how to install the service module hardware, see your Cisco Nexus 7000 Series Hardware Installation and Reference Guide . For details on configuring the NAM, see Configuring the NAM Software.
Hardware Interfaces
The host switch and Cisco NAM-NX1 service module use several interfaces for internal and external communication (see your Cisco Nexus 7000 Series Hardware Installation and Reference Guide ). These interfaces are configurable from the switch using the Cisco NX-OS or the NAM CLI.
Figure 1 depicts the Cisco NAM-NX1 front panel. For a description of the front panel and LED operation, see Reading the NAM LEDs.
To connect your hardware module and configure the interface using the switch, see your Cisco Nexus 7000 Series Hardware Installation and Reference Guide .
Installing Prime NAM Software on the Module
This section covers installation scenarios of Prime NAM software on a Cisco Nexus 7000 Series Network Analysis Module.
NAM ships with Prime NAM software preinstalled. Review the two scenarios that cover installation options and determine which option best fits your needs:
1. No installation required—You received a new NAM module, successfully installed it, and booted to verify the NAM is in the active state. Continue to Configuring the NAM Software.
2. Installation or upgrade required—Your module cannot reboot from the software, perform a new installation, or upgrade to a newer software version. To install your NAM software from the network, see Upgrading the Software.
After your initial installation, if you may want to upgrade to a later version of software if available. See Upgrading the Software for instructions.
Configuring the NAM Software
You must configure the switch to communicate with the NAM and then set the configuration settings on the NAM. Perform the following tasks in the order given:
1. To place NAM in service, configure NAM using the supervisor module. This task includes configuring the VLAN management port and creating a SPAN session from the switch to the NAM. See Switch Configuration Examples for Placing the NAM in Service.
2. Set up the NAM network configuration. See Getting the NAM Up and Running.
Switch Configuration Examples for Placing the NAM in Service
This section includes the following example configurations required on the Cisco switch:
VLAN Management Port Configuration
This section describes the steps to follow in order to assign the NAM to a virtual device context (VDC) from the switch. The steps include:
1. Assign the NAM Ethernet interfaces to a VDC.
2. Create a VLAN if one does not exist.
3. Assign access to the VLAN for the NAM management port.
Once you complete these steps, continue to the next section to continue setting up a SPAN session to direct traffic to NAM. See SPAN Session from Nexus 7000 Series Switch.
This example shows how to configure a VLAN for NAM management traffic and how to assign that VLAN to the NAM management port. All commands must be executed in the VDC to which NAM belongs.
To assign the NAM to a virtual device context (VDC) from the switch:
Step 1 Verify that NAM is active:
Step 2 If you use the default VDC configuration, the NAM interfaces will be allocated to the default VDC automatically.
a. To verify the configuration, use the command show run vdc :
Note As long as the f2e keyword is present in the output, you can install the module in an empty slot and power it up. The interfaces will be allocated automatically. If the f2e keyword is missing (due to prior configuration), you need to add it as shown in step b. The f2e keyword must be present in the configuration before the module is powered up.
b. If you are not using the default VDC configuration, manually allocate the NAM interfaces to the VDC:
Step 3 (Optional) If you already have a VLAN created, skip this step. To create a VLAN to use for NAM management traffic:
Step 4 Add the VLAN to the external interface that is used to access the NAM:
NoteYour configuration is dependent on your network setup. The following is an example of one of the many ways to provide external connectivity.
Step 5 Assign the VLAN to the NAM management port:
SPAN Session from Nexus 7000 Series Switch
To share traffic between your switch and the NAM, you must create a SPAN session that sets the NAM as the destination for the Cisco Nexus 7000 switch traffic. This section provides two example SPAN sessions commands that set the NAM as the destination for the Cisco Nexus 7000 switch traffic.
destination analysis-module <module #> data-port <port #>
The following example shows the creation of a SPAN session from the Cisco NX-OS CLI. This is the preferred method to create the SPAN session.
In this example, a simple SPAN session is used to direct traffic received on interface 4/1 to data-port 1 on the NAM module. Use this example to create a similar SPAN session for your NAM.
NoteRemember to replace the IP address, netmask, and gateway in the example with information appropriate to your switch setup.
destination interface port-channel <port-channel #>
In this example, a SPAN session sets up the module as the destination using the port channel interface. Use your Nexus 7000 Series supervisor CLI setting to create a similar SPAN session for your NAM.
NoteDonot use the destination interface ethernet command as it will result in an error.
For additional details on how to set up various traffic sources, see the Cisco Prime Network Analysis Module Software User Guide .
Getting the NAM Up and Running
After assigning the NAM to a VDC and setting up your SPAN network traffic, go to your VDC to set up the NAM IP configuration and enable the web server.
This section describes how to set the NAM IP configuration and enable the NAM web server and browser-based access to the NAM graphical user interface (GUI). After you perform these tasks, the NAM is in service. Each task includes a basic example. Your configuration setup may require different input.
NoteYou can enable the NAM to function as an HTTP server or an HTTPS secure server, but not as both simultaneously.
To configure the module’s network configuration parameters:
Step 1 Open a session on the switch CLI:
Note Ensure that you are in the correct VDC. You can use the switchto vdc command to change VDCs.
If you have not changed the root password, enter a new password to ensure security.
Tip The default username and password for the NAM is root/root. As part of the installation, change the password first, although the NAM accepts anything including the default.
Step 2 Enter your IP address, network mask, and default gateway.
Step 3 Enable either an HTTP or HTTPS server.
a. To enable the NAM HTTP web server:
b. To enable the NAM HTTPS secure web server:
Step 4 Enter the web admin username and password.
NoteWe recommend that you change the admin password. This document is available to the public by way of Cisco.com, so all default passwords should be changed as soon as possible.
Step 5 Optionally, enable Telnet or SSH if needed.
Step 6 To verify network connectivity to a known address, use the ping command:
The NAM is now on the network and is accessible using the management IP address.
Step 7 To access the NAM and confirm connectivity, use an approved Firefox or Internet Explorer browser.
NoteFor a list of supported browsers, see theCisco Prime NAM Release Notes.
The only access to the NAM web server is the administrative user you configured when you enabled the web server. There is no secondary user option. To configure more users, see the Prime NAM Command Reference Guide or the Prime NAM User Guide on Cisco.com .
Installing and Configuring External Storage
The Cisco Nexus 7000 Series Network Analysis Module offers external storage connectivity for extended capture durations and higher capture bandwidths.
This connectivity is provided through the Mini Serial Attached SCSI (SAS, SFF-8088). The external SAS storage array is directly attached.
See Figure 2 for an overview of external data storage setup.
Figure 2 External Storage Setup
Configure the Storage Array
Reference your vendor user guide for proper configuration of the array. The NAM is independent of most array settings, but some are important for accessibility and performance.
When configuring the Logical Unit Numbers (LUNs) on the array, there is often a Segment Size setting. Larger segment sizes can improve write speeds. Use a segment size as large as possible, up to 512 KB. Multiple LUNs can be configured on a single array. This module supports up to 32 LUNs.
It is important to map the module SAS address to the LUNs. Most storage arrays require this mapping for security reasons, ensuring that only certain hosts (for example, a NAM) can access the LUNs. Each NAM has a unique SAS address, so this step must be performed for each NAM and for each LUN.
The NAM SAS address can be found using the CLI command remote-storage sas local-address . Many storage arrays automatically detect the SAS address once connected to the NAM.
Some SAS storage arrays do not properly negotiate the SAS base address of the front panel port. The port is a wide port because it consists of four SAS lanes. Each lane has its own SAS address, and any one of the four addresses can be considered the base address for the wide port. Ensure you map all four SAS addresses in the storage array configuration.
The previous remote storage CLI command returned a SAS address of 5003223000000000 for the first lane. The other three lanes have consecutive addresses: 5003223000000001, 5003223000000002, and 5003223000000003. All four of those addresses need to be mapped in the storage array configuration.
Connect the Storage Array
After the storage array is configured, connect it to the NAM using the SFF-8088 cable. The module supports SFF-8088 cables up to 6 M. Be sure to use the correct host-connect port on the array as indicated by the vendor user guide. The array can be connected while the NAM is running.
Some arrays come with multiple storage controller modules, and the module ownership must often be mapped to each LUN. This mapping is a common security feature.
The LUN number can help you identify one LUN from others of the same external storage array. This number is unique to each particular array, meaning two LUNs from different arrays can have the same number. If the new LUNs do not show up in the list, then the NAM cannot access them. This problem is likely due to a configuration error on the array.
You can now use the SAS external storage from within the NAM. For more information, see the Cisco Prime Network Analysis Module Software User Guide .
Upgrading and Recovering Your Software
Cisco occasionally provides upgrades to Prime NAM software that you can download and install on your module. You may also need to restore your module software in the case of a catastrophic failure.
Before upgrading your NAM software, we recommend that you backup your configuration as explained in Backing Up Your Configuration.
After upgrading or restoring your module software, you can restore that configuration and resume network monitoring if you previously backed up your configuration.
To perform a new software installation or upgrade, download a version of the current Prime NAM software and use a single CLI command.
To upload your saved configuration to an archive server, use the command-line interface.
To perform a recovery installation when your can no longer boot the NAM application, use the helper utility.
To restore your previous NAM configuration, use the command-line interface. (Optional)
Backing Up Your Configuration
Before you begin the upgrade process, we recommend that you perform a complete backup of your current NAM configuration. This includes the unique changes you have made to the NAM using the GUI or CLI. Any local data is not saved.
NoteEnsure you have a backup configuration file. You can save time and frustration if you need to reformat or repartition due to a hard disk failure.
To back up your current configuration, use the NAM CLI config upload command like the following:
config upload ftp:// user:password@server//path/filename
config upload ftp:// admin:secret@10.10.10.10//archive/nam_config
The config upload command sends a copy of the NAM 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 NAM _host-nam-nx1-6.0.config . The destination address must be a valid server name and directory path where you have read and write permissions. If a filename is not identified, NAM creates a default file name.
Upgrading the Software
To install the software if the module is not booting properly or to upgrade to a newer software version:
Step 1 To download the NAM application software from Cisco.com enter the following URL:
http://software.cisco.com/download/navigator.html
Step 2 Select Cloud and Systems Management > Network Analysis Module (NAM) Products and download the file that begins with nam-nx1, as in nam-nx1.x-x-x.bin.gz (where x-x-x is the NAM software release number). The file is described as the NAM Application Image.
Step 3 Download the NAM application software to the same server where you archived your NAM configuration.
Step 4 Use the commands as needed from the list of upgrade commands shown in Table 1 .
For example, use the NAM CLI command upgrade to perform the software upgrade:
Performing a Recovery Installation
If your module suffers a catastrophic event, such as hard disk corruption, and you can no longer boot the NAM application, use the helper utility to reinstall Cisco Prime NAM application software.
To access the helper utility to install the NAM recovery and NAM software images, perform the following procedure on the switch CLI console:
NoteLog in with user or admin privileges to perform this task.
Step 1 Download both the NAM recovery and software images from Cisco.com to a connected TFTP server.
The recovery helper file contains the term helper (for example, nam-app-x86_64.6-0-1-lfbff-helper.SSA ).
Step 2 Ensure that the NAM module is set up for the correct VLAN using the supervisor CLI.
where X is the slot where the NAM module is placed and YY is the routable VLAN to use for NAM connectivity.
Step 3 Reset the NAM module on the supervisor (SUP) CLI:
where X is the slot where the NAM module is located.
Step 4 Access the NAM console from the SUP CLI:
where X is the slot number where the NAM module is located.
You see a boot up sequence on the session terminal, or a rommon prompt. You must get to the rommon prompt to start the recovery process.
Look for this output during bootup:
Step 5 Press Esc within 10 seconds to see the rommon prompt.
Step 6 After the rommon prompt displays, set up networking by adding your parameters for the TFTP server and file path variables.
The following list describes the parameters that must be set:
– IP_ADDRESS—NAM IP address on the switch vlan as designated on the switch
– DEFAULT_GATEWAY—Gateway for the vLAN as designated on the switch
– IP_SUBNET_MASK—Subnet mask on the switch vlan as designated on the switch
– IMG_FILE—Path and name of NAM application image
– TFTP_SERVER—TFTP server to use for downloading the recovery image
– IMAGE – Complete path to and including the recovery image on the TFTP server
where 10.1.2.3 is a running TTP server reachable from the supervisor and IMG_FILE is set to your path and NAM filename.
Step 7 Boot the recovery helper:
Step 8 Look for the NAM helper menu. Something similar to the following displays on the console:
At some point, the menu displays:
Step 9 Set up the network parameters using the n menu item.
Step 10 Select 1 to configure the network manually and follow the prompts.
Step 11 When you have finished, enter r to return to the main menu.
Step 12 Download and install the NAM image. For recovery, always select menu item 2 .
Download NAM application image via ftp/http and reformat & write to HDD URL of application image []:Step 13 Enter the full URL path to the NAM image that you used in Step 1. Press Enter , and confirm the installation when prompted.
Step 14 Boot into the NAM application.
Once the installation is complete, the main menu displays.
Step 15 Press r to reboot to the newly installed NAM application.
If you are still on the console, you see the rommon bootup sequence as well as the NAM bootup sequence. Wait for the NAM login prompt. No user interaction is needed until that point is reached.
Step 16 Log in as the root user using the root password.
The NAM CLI displays. The recovery is complete.
To configure the NAM, proceed to the Getting the NAM Up and Running. Then, if available, restore any saved data once the configuration is complete.
Restoring Your Configuration
To restore your NAM configuration file after a system recovery, access the NAM configuration back-up file using FTP or HTTP.
config network ftp:// user:password@server//path/filename
config network ftp:// admin:secret@172.10.10.11//archive/nam_config/NAM_host-nam-nx1.6.x.x.config
Performing Advanced Tasks
This section describes some advanced tasks that you may need to perform.
- Resetting the NAM Root Password to the Default Value
- Accessing NAM Using a Telnet or SSH Session
- Moving Your NAM to a New VDC
Resetting the NAM Root Password to the Default Value
If you have forgotten the root password and need to reset it to the default value, enter the following from the switch: clear service module slot x password .
For information about how to reset the NAM root password to the default value from the NAM, see the Cisco Prime Network Analysis Module Software User Guide .
Accessing NAM Using a Telnet or SSH Session
This procedure explains how to open and close a Telnet or SSH session to the NAM. This procedure is not commonly performed, because you would typically use the NAM GUI to monitor and maintain the NAM. If, however, you cannot access the GUI, you may want to use Telnet or SSH to troubleshoot from the NAM CLI.
- Configure the NAM system IP address. Optionally, set the NAM system hostname.
- Verify NAM network connectivity by performing one of the following ping tests:
– From a host beyond the gateway, ping the NAM system IP address.
– From the NAM CLI, ping the NAM system default gateway.
Step 1 telnet { ip-address | hostname }
or
ssh { ip-address | hostname }Step 2 At the login prompt, enter root .
Step 3 At the password prompt, enter your password.
or
If you have not changed the password from the factory-set default, enter root as the root password.Step 4 Perform the tasks using the NAM CLI. When you want to end the Telnet or SSH session to the NAM and return to the Cisco IOS CLI, complete Step 5 and Step 6
For more details on NAM CLI, see the Prime NAM Command Reference Guide .
Examples
Opening and Closing a Telnet Session to the NAM Using the NAM System IP Address
Opening and Closing an SSH Session to the NAM Using the NAM System Hostname
Moving Your NAM to a New VDC
This section describes how to move your NAM to another virtual device context (VDC).
Before you begin, ensure the VDC has been created and is set to accept F2e type modules.
Add the f2e keyword if it is not present in the configuration.
For more details on how to check if the NAM can be moved to your VDC, see your Cisco Nexus 7000 product documentation.
Ensure that you are in the correct VDC by using the switchto vdc command.
The following example shows the commands to perform for the move.
Troubleshooting and Reference
The service modules undergo extensive testing before they leave the factory. If you encounter problems, use the information in this section to help isolate problems or to eliminate the module as the source of the problem.
NoteThe procedures in this section assume that you are troubleshooting the initial Cisco NAM-NX1 startup, and that the module is in the original factory configuration. If you have removed or replaced components or changed any default settings, these recommendations may not apply.
This section covers some trouble events that may occur on a module. It focuses on those events that may frequently occur.
- Troubleshooting Guidelines
- Shutting Down and Starting Up the Cisco NAM-NX1
- Reading the NAM LEDs
- Replacing the NAM Memory or Hard Disk
More troubleshooting and frequently asked questions can be found in the Cisco Prime Network Analysis Module Software User Guide .
Shutting Down and Starting Up the Cisco NAM-NX1
Caution Do not remove the NAM from the switch until the module has shut down completely and the STATUS LED is OFF. You risk disk corruption if you remove the module from the switch before the NAM completely shuts down.
To avoid corrupting the NAM hard disk, you must correctly shut down the NAM before you remove it from the chassis or disconnect the power. You can initiate this shutdown procedure by entering commands at the supervisor module CLI prompt or the NAM CLI prompt. To ensure a graceful shutdown, use the CLI command out-of-service module <module_number> .
Step 1 Open a session on the switch CLI:
Note Ensure that you are in the correct VDC. You can use the switchto vdc command to change VDCs.
NoteIf disk corruption occurs, you can recover the disk by upgrading the application image again with the--reformat option.
The shutdown process can take several minutes. The STATUS LED turns off when the NAM shuts down and then blinks red. For more details on the shutdown and start up commands, see the Cisco Prime NAM Command Reference Guide .
Reading the NAM LEDs
This section describes the location and meaning of the LEDs for the module.
Figure 1 shows the front-panel LEDs for the NAM module. Table 1 defines the LED states.
Table 2 Front Panel LED Descriptions
Replacing the NAM Memory or Hard Disk
The NAM memory or hard disk can be replaced using the following instructions:
NoteFor safety precautions, see theSafety Guidelines section.
Warning Use an ESD or antistatic wrist strap, a conductive foam pad or mat (recommended), and follow all necessary antistatic standards when handling hard disk drives.
Step 1 Shut down the module using the CLI out-of-service module module_number to ensure a graceful shutdown. Wait until the lights go off and unplug it.
Step 2 Carefully remove the NAM module out of the switch slot.
Step 3 To remove old memory DIMMs, push down on the white latches. All size DIMMs are uncovered, not screwed in, and not soldered, and there is no other component blocking them, so they can be easily removed.
Step 4 Follow all necessary antistatic standards in handling the hard disk drives.
Step 5 If a hard drive is already installed, you can remove it by unfastening the four screws that attach it to the drive tray with a Number 2 Phillips screwdriver.
Step 6 Install the new DIMMs or hard drive. Avoid extra force when removing and inserting DIMMs.
Step 7 Plug the module back into the slot. You would see the STATUS button go red, and then green when it is booting up.
