D-Link Unified Access System Software User Manual 12/10/09 Field Community SNMP Community Name Client IP Address Client IP Mask Access Mode Status Table 54: Community Configuration Fields Description Contains the predefined and user-defined community strings that act as a password and are used to authenticate the SNMP management station to the device. A community string can contain a maximum of 20 characters. By default, the options available in the menu are as follows: • public: This SNMP community has Read Only privileges and its status set to enable • private: This SNMP community has Read/Write privileges and its status set to enable. • Create: Use this option to create a new user-defined community string. Use this field to reconfigure an existing community or to create a new one. A valid entry is a case-sensitive string of up to 16 characters. Taken together, the Client IP Address and Client IP Mask denote a range of IP addresses from which SNMP clients may use that community to access this device. If either (IP Address or IP Mask) value is 0.0.0.0, access is allowed from any IP address. Otherwise, every client's IP address is ANDed with the mask, as is the Client IP Address, and, if the values are equal, access is allowed. For example, if the Client IP Address and Client IP Mask parameters are 192.168.1.0/255.255.255.0, then any client whose IP address is 192.168.1.0 through 192.168.1.255 (inclusive) will be allowed access. To allow access from only one station, use a Client IP Mask value of 255.255.255.255, and use that machine's IP address for Client IP Address. Along with the Client IP Address, the Client IP Mask denotes a range of IP addresses from which SNMP clients may use that community to access this device. Specify the access level for this community: • Read-Only: The Community has read only access to the MIB objects configured in the view. • Read-Write: The Community has read/modify access to the MIB objects configured in the view. Specify the status of this community: • Enable: The community is enabled, and the Community Name must be unique among all valid Community Names or the set request will be rejected. • Disable: The Community is disabled and the Community Name becomes invalid. • If you make any changes to the page, click Submit to apply the changes to the system. If you create a new Community, it is added to the table below the Submit button. • Click Delete to delete the selected SNMP Community. TRAP RECEIVER CONFIGURATION Use the Trap Receiver Configuration page to configure information about the SNMP community and the trap manager that will receive its trap packets.
