Setting Up SNMP Traps for Windows NT Servers

Windows NT Servers

To configure a Windows NT server to send SNMP traps to one or more enterprise management consoles, you need to configure each SNMP service on the server to make sure that:

  • The server lists the community string or community name of the enterprise management console.

  • The server lists the enterprise management console as the recipient of traps from the Windows NT agents software.

Checking the Community String

You can use the default community name or community string of public. However, choosing a community name other than public provides more security because it limits the communication to only those computers that have the specified community string.

To set the community string for Windows NT 4.0:

  1. In the Control Panel window, double-click the Network icon, and then click the Services tab if it is not already selected.

    In the Network Services list, scroll to the SNMP service, click once to select it, and then click Properties.

    The Microsoft SNMP Properties window is displayed.
  2. NOTE: If you do not have the SNMP service installed, you can install it by clicking Add in the Network window. The Select Network Service window is displayed, from which you can select SNMP Service. You need to insert the Windows NT 4.0 CD to enable the computer to copy the necessary files for the SNMP service.

  3. Click the Security tab in the Microsoft SNMP Properties window to display the Security settings.

  4. Make sure that the community name or community string that you want to use for the server is specified in the Accepted Community Names list.

    If the name is not already on the list, click Add to display the SANscape window. Type the new name in the entry field and click Add in that window. The Security tab is displayed with the new name on the Accepted Community Names list.

    NOTE: Community names or community strings are case-sensitive.

  5. (Optional) If desired, change the default setting of Accept SNMP Packets from Any Host to Only Accept SNMP Packets from These Hosts and add the network address of the enterprise management computer that receives the traps from the SANscape Agent on the server.

    Using this setting provides more security because it lets you specify the computer or computers from which the Windows NT agents accept information.

    To add the network address of the computer with SANscape management console software to the lower list box, click Add to access the Security Configuration window. Type the IP address in the Entry box and click Add in that window. The Security tab reappears with the SANscape management console computer’s address.

  6. Click OK.

Specifying the Trap Recipient

In this procedure, you are listing the enterprise management console as a recipient of traps from the server.

NOTE: For the procedure, you need the IP address of the enterprise management console that receives the traps. The procedure also requires the same community name as specified in Setting Up Servers for Traps.

The steps for specifying an enterprise management console computer as the recipient of the agent traps are as follows.

  1. Click the Traps tab of the Microsoft SNMP Properties window to display the Traps settings.

  2. Make sure the same community name is specified as the community name that was indicated in the Security tab earlier.

    If you need to correct the community name, type the name in the Community Name field and click Add. If another name is already in the entry field, it is retained after you type over it. To remove a name, select it and click Remove.

  3. Add the IP address of the enterprise management console in the Trap Destinations list.

    1. Click Add.
      The Service Configuration window is displayed.

    2. Type the IP address in the Entry field and click Add.
      The Traps tab is displayed with the new network address in the Trap Destinations list.

    3. Type each IP address in the following format: AAA.BBB.CCC.DDD
      You do not need to type leading zeros. An example of an appropriate address is: 192.168.100.1

  4. If you want to send optional SANscape traps to another enterprise management console, type the network address of that management workstation.

    If you have more than one enterprise management console, each one needs to have its address indicated here.

  5. Click OK to confirm your settings.

  6. Click Close to leave the Network window.

  7. Exit Windows NT and restart the server.

    If you are planning to install SANscape, you do not have to reboot until after you install the software.
