Evaluation License

If you request a Management Center evaluation license, you receive an Entitlement ID. This Entitlement ID allows you to generate a product evaluation license key. Refer to the instructions included with the Entitlement ID to generate the license key. Use the key when you install the product.

To install Management Center using an evaluation license, refer to the Management Center Installation instructions for Windows or Linux contained in this guide.

To upgrade from an evaluation license to a purchased license, see the instruction in the Upgrading an Evaluation License section.

Extreme Management Center Services

During the Management Center installation, you can enable the Management Center Services, allowing it to run in the background on the Management Center server. The service starts automatically by default, and if you shut down and restart the machine, the service is restarted automatically.

You can also restart the services manually or disable a service so it does not start automatically when you restart the server. For information on how to do these procedures, see Extreme Management Center Services under the Suite-Wide Tools User Guide.

The services offered depend on whether your platform is Windows or Linux.

  • SNMPTrap Service (Windows and Linux) - Enables SNMP trap messages to be received and logged when problems or irregularities are detected on network devices. Only one trap service may be running at a time on a server. If you are also running a network management system on the server, you may wish to use the network management trap service.
    Windows Users: Windows users should check for and stop any other SNMP trap service before enabling the Management Center version (see Stop Other Services).
  • TFTP (Windows and Linux) - Enables you to upload and download configuration files, and download firmware to devices. Only one TFTP service may be running at a time on a machine.
     NOTE:The Management Center TFTP Service does not support IPv6.
    Windows Users: Windows users should check for and stop any other TFTP service before enabling the Management Center version (see Stop Other Services).
    Linux Users: Typically, the TFTP service that exists in Linux is disabled; however, if it is enabled, you may wish to disable it and enable the Management Center version of TFTP which provides additional features for Management Center. If you elect to enable the Management Center version on the Linux platform, you must first disable the Linux TFTP service and perform some configuration as follows:
    1. Using a text editor, edit the file /etc/xinetd.d/tftp
    2. Set disable = yes
      Sample file:
      service tftp
      { flags = REUSE
      socket_type = stream
      wait = no
      user = root
      server = /usr/sbin/in.tftp
      disable = yes
      }
    3. Then run: /etc/rc3.d/S56xinetd restart
  • BOOTP (Windows only) - Enables the Management Center server to also be a BOOTP server. This allows the server to supply devices with firmware images (or other basic identity information) in the event the device's current firmware image becomes corrupt. Only one BOOTP service can be running at a time on a machine.
  • Syslog (Windows only) - Management Center Console maintains a record of syslog messages in the Syslog tab of the Event View.

Upgrade Information

Extreme Management Center 7.1 supports upgrades from NetSight 6.3 and 6.2. If you are upgrading from a NetSight version prior to 6.2, you must perform an intermediate upgrade. For example, if you are upgrading from NetSight 6.0, you must first upgrade to NetSight 6.2, and then upgrade to Management Center 7.1.

Upgrading to Management Center version 8.0 (available March, 2017) is only supported from version 7.1

  IMPORTANT: When performing an upgrade, be sure to backup the Management Center database prior to performing the upgrade, and save it to a safe location. Use the Server Information window to perform the backup. From the menu bar, access Tools > Server Information and select the Database tab.

During the installation you have the option to backup additional user files by selecting a checkbox on the Previous Installation Detected screen. This option lets you backup user files such as Inventory Manager archive files not automatically backed up during the install because the backup could take several minutes.

Important Upgrade Considerations

  • If your network is using Application Analytics engines, you must first perform the Management Center upgrade to version 7.1 and then upgrade the Application Analytics engines.
  • If you are running Data Center Manager (DCM), a Mobile Device Management (MDM) integration, or other OneFabric Connect or Fusion integration with Management Center:
    • The OneFabric connect module is disabled on upgrade, and requires a new version in order to operate with Management Center 7.1. You must install an updated module that supports Management Center 7.1. Contact your account team for information on obtaining this update.
    • You must install a Management Center Advanced (NMS-ADV) license with 7.1 when you upgrade. Contact your account team for information on obtaining this license.
  • If you are accessing Web Services directly or through OneFabric Connect you need to install a Management Center Advanced (NMS-ADV) license. Contact your account team for information on obtaining this license.
  • When upgrading a 64-bit Management Center server or when upgrading from a 32-bit to a 64-bit Management Center server, if the -Xmx setting is set below 1536m, it is increased to 1536m.
  • Older NetSight licensing keys (starting with INCREMENT) are no longer supported as of NetSight 5.0 and later. If you have one of these keys, please contact Extreme Networks Support for license upgrade information.
  • The 4.xx version of the NAC Request Tool is not compatible with the 7.1 Management Center server. If you are using the NAC Request Tool you need to upgrade the version of NAC Request Tool to version 7.1.

Upgrading an Evaluation License

To upgrade from an evaluation license to a purchased copy, contact your Extreme Networks Representative to purchase the software and receive an Entitlement ID. You do not need to reinstall the software to perform the conversion.

Prior to installing Management Center, you should redeem your Entitlement ID for a product license key. Refer to the instructions included with the Entitlement sent to you.

If your Evaluation copy has not expired:

  1. From the Management Center Console menu bar, select Tools  > Server Information.
  2. In the Server Information window, click the License tab.
  3. Select NetSight Evaluation from the table and click Add License.
  4. Read and accept the License and click OK.
  5. Enter the license text that you received when you generated the product license key.
  6. Click Update. The license file is updated with the new license text.

If you have let your Evaluation Copy expire, when you launch Console a window opens where you can enter the license text.

Upgrading to Extreme Management Center NAC Manager 7.1

Important Captive Portal Changes

In NetSight 6.0, the NAC captive portal was enhanced to provide a more modern look and feel. If you have used the custom style sheet, you need to review pages, as there are likely be changes required to allow the custom styles to display correctly with the new page layout. After upgrading, Extreme Access Control administrators should log on to the screen preview page (https://<Extreme Access ControlengineIP>/screen_preview) of the NAC captive portal to verify that the portal still looks acceptable for display to end users. If your portal configuration is limited to setting colors and images, there should be no problem with the new portal look and feel, although you may want to set some of the new color options.

General Upgrade Information

When upgrading to Management Center NAC Manager 7.1, you are not required to upgrade your Extreme Access Control engine version to 7.1. However, both NAC Manager and the Extreme Access Control engine must be at version 7.1 in order to take advantage of the new Access Control 7.1 features. Management Center NAC Manager 7.1 supports managing Extreme Access Control engine versions 6.3 and 6.2.

  NOTE: NAC 7.1 is not supported on the 2S Series and 7S Series NAC Controllers. You cannot upgrade NAC Controllers to version 7.1, but you can use NAC Manager 7.1 to manage controllers running version 4.3.xx.

You can download the latest Extreme Access Control engine version at the Network Management Suite (NMS) Download web page http://extranet.extremenetworks.com/downloads/Pages/NMS.aspx. Be sure to read through the Upgrading to NAC 7.1 document (available on the Extreme Management Center (NetSight) Documentation web page > Manuals & Release Notes > NetSight 7.1 > Network Access Control [NAC]) for important information.

In addition, if your NAC solution utilizes a Nessus assessment server, you should also upgrade your assessment agent adapter to version 7.1 if you upgrade to NAC 7.1.

Agent Version for NAC Agent-Based Assessment

If you are using onboard agent-based assessment, be aware that the agent version is upgraded during the Extreme Access Control engine software upgrade. If you would like end-systems to update their agent to the new version, you must configure your assessment test set to test for the new agent version. Refer to the Upgrade Information section in the Extreme Management Center Release Notes for the agent version included in the Extreme Access Controlengine software.

Upgrading NAC Request Tool

The 4.xx version of the NAC Request Tool is not compatible with the 7.1 Management Center server. If you are using the NAC Request Tool, you will need to upgrade your version of the NAC Request Tool to version 7.1.

Upgrading to Extreme Management Center 7.1

  • Beginning in 5.1, all Extreme Management Center maps intended to utilize the advanced map features of wireless coverage and client location triangulation should be created with a Base Map type of Floor Plan. Management Center maps created in NetSight version 4.4 or 5.0 that include both APs and walls are automatically converted to the Floor Plan Base Map type when the upgrade is performed. This allows Floor Plan map features to be available for those maps.
  • Beginning in 5.1, managed wireless controllers (8.32 or later) are automatically synchronized to match Management Center map floor plan data. If the floor plan data defined in Management Center maps is not consistent with data on the controller, the controller is updated accordingly.

Upgrading to Policy Manager 7.1

  • Policy Manager 7.1 only supports ExtremeWireless Controller version 8.01.03 and higher. If you upgrade to Management Center 7.1 prior to upgrading your controllers, then Policy Manager does not allow you to open a domain where the controllers already exist or add them to a domain. A dialog is displayed indicating your controllers do not meet minimum version requirements and that they must be upgraded before they can be in a domain.
  • Policy Manager 5.0 changed how it handles rule containment VLANs and Role VLAN Egress VLANs. This may cause Verify to fail following an upgrade to 7.1. If this happens, enforce the domain configuration to update the static VLAN table.
  • Following an upgrade to Wireless Controller version 8.31 and higher, a Policy Manager enforce fails if it includes changes to the default access control or any rules that are set to contain. To allow Policy Manager to modify the default access control or set rules to contain, you must disable the "Allow" action in policy rules contains to the VLAN assigned by the role checkbox accessed from the Wireless Controller's web interface on the Roles > Policy Rules tab. This will allow the enforce operation to succeed.

Upgrading to Wireless Manager 7.1

Following a Wireless Manager upgrade, you should clear the Java Cache before starting the Management Center client.

Pre-Installation Checklist

Please review the following checklist prior to performing an Extreme Management Center software installation or upgrade.

  • Backup database. If performing an upgrade, be sure to backup the Management Center database prior to performing the upgrade. Use the Server Information window to perform the backup (Tools > Server Information > Database tab).
  • Disable antivirus software. Disable any antivirus software running on the Management Center server prior to beginning the installation. Be sure to re-enable the antivirus software following the install. If you have installed or upgraded Management Center on a Windows platform system, follow the instructions in Configure Antivirus Software before you re-enable the antivirus software.
  • Generate your Extreme Management Center product license key. When you purchased Management Center, you received a Licensed Product Entitlement ID for the license that you purchased. This Entitlement ID allows you to generate a product license key. Refer to the instructions included with the Entitlement ID to generate the license key. The key will be used when you install the product.

  11. The application main window opens.

Performing a Silent Install

If you are installing Management Center on a Linux system that doesn't support a GUI, you must add the cli flag (--cli) to the install command, in order to allow the Management Center installer to prompt for any required input.

Start the installation with the following command:

./NetSight_Suite_<version>_install.bin --cli

If you are installing as a user other than root, you must use the --user command to specify the different user. The user must already be configured on the machine before you install. For example:

./NetSight_Suite_<version>_install.bin --cli --user <username>

To perform the install and create a new local "netsight" user (where netsight is the user name), use the --password command to set the password for the new "netsight" user. For example:

./NetSight_Suite_<version>_install.bin --cli --password <password>

Restoring a Database from a Windows Server to a Linux Server

This section describes several Management Center configuration changes required if you are moving your Management Center installation from a Windows platform system to a Linux platform system. The steps are performed after restoring your database to the new server. (For information on restoring a database, see the Server Information help in the Extreme Management Center Suite-Wide Tools User Guide.)

When restoring a saved database to a new Management Center server installation, any memory or database configuration changes on the original server will require a manual change on the new server in order to replicate the configuration of the original Management Center server.

  • Changes to the default -Xmx memory settings in the <install directory>\services\nsserver.cfg file need to be duplicated on the new server when the database is restored. To change the memory setting to match the previous server, stop the Management Center server and edit the nsserver.cfg file.
  • The mySQL my.ini file also need to be manually updated to match any changes made on the original server. For instructions on modifying the my.ini file, see the Change the MySQL my.ini File section in the NAC Deployment Guide.

In addition, there are two changes that must be made in the legacy Console java application and one change in the legacy Inventory Manager application.

Console

Use the following instructions to change the location of syslog and trap information to the new location on the Linux system.

Syslog

Change the Syslog Log Manager to point to the new location on the Linux system. This allows the display of syslog information in the Syslog Event View tab.

  1. From the Console menu bar, select Tools > Alarm/Event > Event View Manager.
  2. Click on the Syslog entry under Available Log Managers, and click the Edit button. The Log Manager Parameters window opens.
  3. Change the path in the Log Directory field to /var/log/syslog.
  4. Change the Pattern to Red Hat LINUX Syslog Pattern.
  5. Click OK.
Traps

Change the Traps Log Manager to point to the new location on the Linux system. This allows the display of trap information in the Traps Event View tab.

  1. From the Console menu bar, select Tools > Alarm/Event > Event View Manager.
  2. Click on the Traps entry under Available Log Managers, and click the Edit button. The Log Manager Parameters window opens.
  3. Change the path in the Log Directory field to %logdir%/traps.
  4. Click OK.

Inventory Manager

If you are using Inventory Manager, you need to change the Data Storage Directory path to point to the new location on the Linux system. The Data Storage directory is where all Inventory Manager data is stored, including capacity planning reports, configuration templates, archived configurations, and property files.

  1. From the Inventory Manager menu bar, select Tools > Options. Expand the Inventory Manager options folder and select Data Storage Directory Path.
  2. Change the path to the correct new location. On a default Linux install, the path would be: <user's home directory>/appdata/InventoryMgr
  3. Click OK.

Systems with Multiple NICs

This section provides instructions for configuring Extreme Management Center servers with multiple NICs (Network Interface Cards). During the startup process, the Management Center server automatically binds to the first available NIC, which may not be the correct interface for the server to use. In addition, changes on the network can cause the server to bind to an incorrect interface, should the server restart during a change.

If the system has multiple NICs installed, it is a good practice to either:

  • configure the server to bind to a preferred IP address, if using only one interface for connections or
  • configure multiple network interfaces, if using more than one interface for connections.

This ensures that local and remote clients, as well as Extreme Access Control engines, are able to connect to the Management Center server.

Binding to One Interface

If the Management Center server has multiple NICs installed but only one interface is used to access Management Center, use the following instructions to configure the preferred interface for the Management Center server.

On Windows systems, you will need to set the binding order of the network interface cards and configure the Management Center server to bind to the correct address. On Linux systems, you need to configure the Management Center server to bind to the correct address.

Windows Systems

Set the binding order of multiple network interface cards and configure the Management Center server to bind to the correct IP address. These steps may vary depending on your operating system.

  1. Open the Network Connections window:
    1. Click Start > Run.
    2. Enter ncpa.cpl and click OK.

    The Network Connections window opens. You can view the available connections in the LAN and High-Speed Internet section of the window.
  2. From the Network Connections window menu bar, select Advanced > Advanced Settings. The Advanced Settings window opens.
  3. The Adapters and Bindings tab lists the connections in the order in which the connections are accessed by network services. The NIC that the Management Center server connects to must be first in the list. You can use the arrow buttons to change the binding order.
  4. Open the .netsight file. Edit the line JBOSS_HOSTNAME=<server IP> to add the correct NIC IP address. (On Windows Server 2008 and Windows 7, the file is located at C:\ProgramData\Extreme Networks. On Windows Server 2003, the file is located at C:\Documents and Settings\All Users\Application Data\Extreme Networks.)
  5. Restart the Management Center server.

Linux Systems

Configure the Management Center server to bind to the correct IP address.

  1. Open the /var/Extreme_Networks/.netsight file. Edit the line JBOSS_HOSTNAME=<server IP> to add the correct NIC IP address.
  2. Restart the Management Center server.

Configuring Multiple Interfaces

If the Management Center server has multiple NICs installed and you need to access Management Center on multiple interfaces, use the following instructions to configure multiple network interfaces for the Management Center server.

  1. On the Management Center server, add the following text to the <install directory>/appdata/NSJBoss.properties file. In the second to last line, specify the hostname of the Management Center server.
    # In order to connect to a NetSight server behind a NAT firewall or a
    # NetSight server with multiple interfaces you must define these two
    # variables on the NetSight server. The java.rmi.server.hostname
    # should be the hostname (not the IP) if multiple IPs are being used
    # so that each client can resolve the hostname to the correct IP that
    # they want to use as the IP to connect to.
    java.rmi.server.hostname=<hostname of NetSight server>
    java.rmi.server.useLocalHostname=true
  2. Save the file.
  3. Add the Management Center server hostname to your DNS server.
  NOTE: Multiple interface support has been added to provide support for clients accessing the Management Center server in a configuration where the primary Management Center interface may not be accessible/routable to remote clients, such as in an MSSP environment. This support provides for both visibility and management of network devices for clients accessing Management Center from an additional interface, however some functionality may be limited. For example, TFTP configuration and firmware management of devices located off a second Management Center interface may not function properly.

Remote Client Launch

Management Center is a web-based application you access from the Management Center Login page. Remote Management Center clients can use the following steps to access the Management Center Launch Page and run Management Center applications from the remote client machine.

  1. Open a browser window and enter your Management Center information as a URL in the following format:

    http://servername:8080/

    where servername is the Management Center server's IP address or hostname, and 8080 is the required port number. For example,

    http://10.20.30.40:8080/

  2. The Management Center Login page opens.

    Management Center requires a user login as a way to restrict access to the Management Center server, perform audit trails, and assign user capabilities according to the Authorization Group the user belongs. It is important to note that when you log in, you are authenticating to the operating system of the Management Center server system to which you are connecting.
  3. Enter your username if you are authenticating to a Linux platform server or enter your domain name\username if you are authenticating to a Windows platform server.
  4. Enter your password and click Login.
  5. The application main window opens.

    The first time you log in, the embedded help window displays the Getting Started
  NOTE: User preferences and application data (such as FlexViews and MIBs) for remote clients are stored in the following local directory on the client machine: C:\Documents and Settings\<username>\Application Data\NetSight.
