Chapter 3 Maintenance & Troubleshooting 4.3 Monitor & Control via SNMP Simple Network Management Protocol (SNMP) provides a framework for the definition of management information and the exchange of that information. A SNMP manager is a software module that manages part or all of the system configurations while an agent is a software module in the unit that is being managed. Transfer of information can be initiated by both the manager (via polling) and the agent (via SNMP Trap). By default, the manager initiates requests and receives responses via port 161. The agent sends SNMP Trap messages via port 162. A database describing the unit s application parameters is stored in the SNMP agent. This SNMP Management Information Base (MIB) database is used to interpret the signals requested and received between the manager and agent. The database includes both a standard set of values common to hardware nodes on a network and a private set of values that is unique to the specific unit. Object Identifiers (OID) are a series of numbers that uniquely identify variable to an SNMP agent. OIDs are arranged in a hierarchical tree structure. The figure below shows the categorization of AFOT parameters that are used in defining the MIBs for SNMP enabled Agilis products. Note: This figure shows the full set of categories and does not apply to all Agilis products. The set of parameters that are available in each Agilis product will differ. Figure 4.19 SNMP MIB categories IM02960225 Rev. B 39

Chapter 3 Maintenance & Troubleshooting 4.3.2 Connecting the PC to the AFOT You can monitor and control the AFOT using an SNMP manager via an Ethernet connection.
