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.

  1. For Windows 2000 or Windows 2003, in the Control Panel window, double-click the Administrative Tools icon, and then click the Services tab if it is not already selected.

  2. 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.

    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 might need to insert the Microsoft Windows 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 Service Configuration 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 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.
