When you install Extreme Management Center on a Windows or Linux system, you have the option of enabling (configuring to launch automatically) the Management Center Services.
| NOTE: | If you have performed a silent Linux installation or installed Management Center on the Management Center hardware or virtual engine, the Management Center Services are automatically enabled. |
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.
- 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. - 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.
When you enable a Management Center service, it runs in the background on the workstation. The service starts automatically by default, and if you shut down and restart the workstation, the service is restarted automatically.
There may be times when you want to stop or restart the services manually. For Windows users, Management Center provides a Services Manager that shows you which of the services are running, and lets you stop, start, or restart them individually or all at once. You can also stop and start the Services Manager itself.
In addition, if you are not using a service, you may want to disable the service completely so that it does not start automatically if you restart the system.
The instructions below explain how to manually stop, start, or disable a Management Center service, and how to stop and start the Services Manager on Windows systems.

Stopping and Starting Extreme Management Center Services
The information in this section provides instructions for stopping and starting a service manually on Windows and Linux platform systems.
Windows
You can manually start, restart, or stop Management Center services individually or all at once. On a Windows platform system:
- Go to the Taskbar Notification Area of your desktop (on the lower right of your screen, unless you've relocated your Taskbar).
- Locate the Services Manager
icon (
) and right-click it.
(If you don't see the icon, you can start the Services Manager from the Start > Programs or All Programs menu; select Startup > Services Manager.) - Select the appropriate menu option. Menu options that are not
currently available for the service(s) are grayed out.
- Start - Starts a service that is not currently running.
- Restart - Stops a service that is currently running, and starts it up again immediately.
- Stop - Stops a service that is currently running.
- Start automatic services - Starts any services that have been enabled (configured to launch automatically via selection at installation or in the Services for Extreme Management Center Server window).
- Restart running services - Stops all services that are currently running, and starts them up again immediately.
- Stop running services - Stops all services that are currently running.
- Exit - Stops all currently running services and shuts down the Services Manager.
Linux
You can manually start, restart, or stop Management Center services individually. Restarting a service stops a service that is currently running, and starts it up again immediately. You can also use the status option to determine if a service is running.
On a Linux platform system:
- Navigate to the /etc/init.d directory.
- Type the service name, a space, and either start, restart, stop, or status depending on what you want to do, and press Enter.
These are the service names to use:
- SNMP trap service - nssnmptrapd
- TFTP service - nstftpd
- Management Center Server - nsserver
- Management Center Database - nsdatabase
For example, to stop the SNMP trap service, type:
nssnmptrapd stop
and press Enter.
To determine whether or not the SNMP trap service is running, type:nssnmptrapd status
and press Enter.
On a Management Center Engine or Management Center Virtual Engine:
- Navigate to the /etc/rc.d directory.
- Type the service name, a space, and either start, restart, stop, or status depending on what you want to do, and press Enter.
These are the service names to use:
- SNMP trap service - rc.nssnmptrapd
- TFTP service - rc.nstftpd
- Management Center Server - rc.nsserver
- Management Center Database - rc.nsdatabase
For example, to stop the SNMP trap service, type:
rc.nssnmptrapd
Disabling an Extreme Management Center Service
When a Management Center service is enabled during installation, it restarts automatically if the system is restarted, even if it has been manually stopped. If you are not using a service, in order to prevent the service from automatically restarting during a system restart, you must disable it.
There are several reasons you might want to disable a Management Center service if it is not being used. For example, disabling an unused service can avoid possible port conflicts and conserve system resources. In addition, some installations might require disabling unused services as part of their security process.
The information in this section allows you to disable a service without uninstalling it.
Windows
To disable a Management Center Service on a Windows platform system:
- Open the Windows Control Panel.
- Navigate to Administrative Tools > Services.
- In the Services window, double-click on the Service entry. A Properties window opens.
- On the General tab, set the Startup type to either Manual (if you want to allow the service to be started manually) or Disabled (if you want to completely disable the service). If you are turning off the service for security purposes you should set the Startup type to Disabled.
- Click OK.
Linux
Use the following commands to enable or disable a Management Center Service on a 64-bit hardware or virtual Management Center engine.
- Navigate to the /etc/rc.d directory.
- Type the command update-rc.d, the service name, and either enable or disable, and press Enter.
These are the service names to use:
- SNMP trap service - nssnmptrapd
- TFTP service - nstftpd
For example, to disable the SNMP trap service, type:
update-rc.d nssnmptrapd disable
and press Enter.
To enable the TFTP service, type:update-rc.d nstftpd enable
and press Enter.
Stopping and Starting the Services Manager (Windows Only)
The Management Center Services Manager runs on the Windows platform only.
Stopping
Stopping the Services Manager stops all running Management Center services.
- Go to the Taskbar Notification Area of your desktop (on the lower right of your screen, unless you've relocated it).
- Locate the Services Manager
icon ()
and right click it.
- Select Exit from the menu.
Starting
The Management Center Services Manager automatically starts for the user that performed the Management Center installation. You can manually start the Services Manager using the following instructions. Starting Services Manager starts all Management Center services enabled at installation or via the Tools > Options Services for Extreme Management Center Server window.
- From the Start > Programs or All Programs menu, select Startup > NetSight (Management Center) Services Manager.
