    • management node
    • management information base (MIB)
  10. what does NMS stand for
    network management station
  11. what does MIB stand for
    management information base
  12. what does OID stand for
    object identifiers
  13. what are the default SNMP communities
    • public (read-only)
    • private (read-write)
  14. what are traps
    traps are unsolicited messages sent by the SNMP agent using port 162 in order to notify the NMS of certain error conditions
  15. what is unsolicited messages sent by the SNMP agent using port 162 in order to notify the NMS of certain error conditions
  16. what two new protocol operations does SNMPv2 also define
    • getbulk
    • inform
  17. what is getbulk define by SNMPv2
    • getbulk operation is used by the NMS to efficiently retrieve large blocks of data, such as multiple rows in a table
    • getbulk fills a responsemessage with as much of the requested data as will fit
  18. what is inform define by SNMPv2
    • the inform operation allows one NMS to send traps information to another NMS and to then receive a response
    • if the agent responding to getbulk operations cannot provide values for all the variables in a list, it provides partial results
