Supported Internet ProtocolsThe library supports the following Internet protocols:v IPv4v IPv6To learn more about IPv4, visit http://www.iana.org/. To learn more about IPv6,visit http://www.ipv6.org/.SNMP MessagingOccasionally, the library may encounter a situation that you want to know about,such as an open magazine or a fault that causes the library to stop. The libraryprovides a standard TCP/IP protocol called Simple Network Management Protocol(SNMP) to send alerts about conditions (such as need for operator intervention)over a TCP/IP LAN network to an SNMP monitoring station. These alerts arecalled SNMP traps. Using the information supplied in each SNMP trap, themonitoring station (together with customer-supplied software) can alert operationspersonnel of possible problems or operator interventions that occur.SNMP TrapsSNMP traps are alerts or status messages that can be collected, monitored andused to proactively manage attached libraries using SNMP protocol with the hostserver(s). In summary, each trap provides the following information:v Product Identification such as product name, description, manufacturer, modelnumber, firmware level, and the URL that the trap is designated for.v Product Status such as the severity of the trap, status (current and previous) andthe time the trap occurred.v Library State (physical device status) such as identification and status of devicesthat are monitored. In the case of the library, it would include enclosure, powersupply, controller, magazine status, drive count, cartridge slot count, and I/Ostation count. Also included would be certain library statistics, and whereappropriate, the fault FSC (fault symptom code) including the severity anddescription of that fault.v Drive Status such as the identification of each drive in the library, firmwarelevel, serial number and other address and status information.v Trap Definitions such as library status change, open magazine, I/O accessed,hard fault information, drive cleaning requests, excessive retries and libraryreturning to normal operations. For additional information, refer to Appendix G."SNMP Status MIB Variables and Traps" on page G-1.v SNMP MIBs: The library's Management Information Base (MIB) contains unitsof information that specifically describe an aspect of the system, such as thesystem name, hardware number or communications configuration. Status anderror data is also gathered by MIBs and sent to one or more IP addressesdefined during the SNMP configuration operation.
