    INTRODUCTION TO SNMP Overview How SNMP Works Variables In a Managed Device MIBs and Traps...
  • Page 8 Overview Any protocol for managing networks must allow virtually all network devices and systems to communicate statistics and status information to network management stations, (network managers). This communication must be independent of the primary network transmission medium and impose little effect on the efficiency of the network. Network managers must be able to obtain status information from managed devices, and make changes in the way the managed devices handle network traffic.
  • Page 9 How SNMP Works SNMP is the only protocol that is widely available from many vendors of TCP/IP networks and internetworks. SNMP: Allows management with a simple set of commands. Allows new devices added to a network to be easily managed with minimal intervention.

  • Page 11 Variables In a Managed Device Variables are the means by which a director and other devices keep track of their performance, control their own performance, and provide access to their performance for network managers. A simple example of a variable’s use is to turn off a port (set the variable to 2), or turn the port back on (set the variable to 1).

  • Page 13 MIBs and Traps Standard MIBs are those available with SNMP and designed for standard operation with a wide variety of managed devices. Chapter 2 describes the standard MIBs used by the HP Surestore Director FC-64. Private enterprise MIBs are those provided by the manufacturer of the managed devices to allow management of device-specific items not supported by the standard MIBs.
  • Page 14 SNMP encourages use of the second type of trap to reduce the load on a network. Both types of trap provide the information to the manager, but the second type allows the manager to wait until higher priority tasks are accomplished and poll for additional information in its own time.

  • Page 16: Snmp Management

    SNMP Management SNMP is a transmission control protocol/internet protocol (TCP/IP) that uses the user datagram protocol (UDP) or other protocols such as UDP/IP to exchange messages between an SNMP agent (in a managed device) and a management station residing on a network.
