    Configuring SNMP Communities (NSM Procedure)

    You can configure an SNMP community to authorize access to the SNMP server by SNMP clients, based on the source IP address of incoming SNMP request packets. A community also defines which MIB objects are available and the operations (read-only or read-write) allowed on those objects. The SNMP client application specifies an SNMP community name in Get, GetNext, GetBulk, and Set SNMP requests. If a community is not configured, all SNMP requests are denied.

    To configure SNMP communities in NSM:

    1. In the navigation tree, select Device Manager > Devices.
    2. In the Devices list, double-click the device to select it.
    3. Click the Configuration tab.
    4. In the configuration tree, expand SNMP.
    5. Select Community.
    6. Click the Add or Edit icon.
    7. Enter the parameters as specified in Table 1.
    8. Click one:
      • OK—To save the changes.
      • Cancel—To cancel the modifications.
      • Apply—To apply the SNMP settings.

    Note: After you make changes to a device configuration, you must push that updated device configuration to the physical security device for those changes to take effect. You can update multiple devices at one time. See the Updating Devices section in the Network and Security Manager Administration Guide for more information.
