TL-SG3109/TL-SL3428/TL-SL3452 Gigabit Managed Switch Family Installation Guide 4.4.1.4 SNMP Community Strings Simple Network Management Protocol (SNMP) provides a method for managing network devices. Devices supporting SNMP run a local software (agent). The SNMP agents maintain a list of variables, used to manage the device. The variables are defined in the Management Information Base (MIB). The MIB presents the variables controlled by the agent. The SNMP agent defines the MIB specification format, as well as the format used to access the information over the network. Access rights to the SNMP agents are controlled by access strings and SNMP community strings. The device is SNMP-compliant, and contain an SNMP agent that support a set of standard and private MIB variables. Developers of management stations require the exact structure of the MIB tree and receive the complete private MIBs information before being able to manage the MIBs. All parameters are manageable from any SNMP management platform, except the SNMP management station IP address and community (community name and access rights). The SNMP management access to the switch is disabled if no community strings exist. Note The device switch is delivered with no community strings configured. The community-string, community-access, and IP address can be configured through the local terminal during the initial configuration procedure. The SNMP configuration options are: 31
