xStack® DES-3528/DES-3552 Series Layer 2 Stackable Fast Ethernet Managed Switch Web UI Reference Guide The fields that can be configured are described below: Parameter Description Group Name Type an alphanumeric string of up to 32 characters. This is used to identify the new SNMP group of SNMP users. Read View Name This name is used to specify the SNMP group created can request SNMP messages. Write View Name Specify a SNMP group name for users that are allowed SNMP write privileges to the Switch's SNMP agent. Notify View Name Specify a SNMP group name for users that can receive SNMP trap messages generated by the Switch's SNMP agent. User-based Security Model SNMPv1 - Specify that SNMP version 1 will be used. SNMPv2 - Specify that SNMP version 2c will be used. The SNMPv2 supports both centralized and distributed network management strategies. It includes improvements in the Structure of Management Information (SMI) and adds some security features. SNMPv3 - Specify that the SNMP version 3 will be used. SNMPv3 provides secure access to devices through a combination of authentication and encrypting packets over the network. Security Level The Security Level settings only apply to SNMPv3. NoAuthNoPriv - Specify that there will be no authorization and no encryption of packets sent between the Switch and a remote SNMP manager. AuthNoPriv - Specify that authorization will be required, but there will be no encryption of packets sent between the Switch and a remote SNMP manager. AuthPriv - Specify that authorization will be required, and that packets sent between the Switch and a remote SNMP manger will be encrypted. Click the Apply button to accept the changes made. Click the Delete button to remove the specific entry. SNMP Engine ID Settings The Engine ID is a unique identifier used for SNMP V3 implementations on the Switch. To view the following window, click Management > SNMP Settings > SNMP Engine ID Settings, as shown below: Figure 3-39 SNMP Engine ID Settings window To change the Engine ID, type the new Engine ID value in the space provided. The fields that can be configured are described below: Parameter Description Engine ID The SNMP engine ID displays the identification of the SNMP engine on the Switch. The default value is suggested in RFC2271. The very first bit is 1, and the first four octets are set to the binary equivalent of the agent's SNMP management private enterprise number as assigned by IANA (D-Link is 171). The fifth octet is 03 to indicate the rest is the MAC address of this device. The sixth to eleventh octets is the MAC address. 51
