Abstract

A method for controlling trap generation of an SNMP which is operated between a manager and at least one agent, wherein a TrapFlag field and a Trap Peer field are defined for each management-object resource (each object) in describing an MIB of an SNMP and more than two objects are correlated to define a trap generation condition, so that trap generation can be effectively controlled by defining a trap behavior individually for an object of an SNMP MIB.

Claims

1. A method for controlling trap generation of an SNMP which is operated between a manager and at least one agent, wherein a TrapFlag field and a Trap Peer field are defined for each management-object resource (each object) in describing an MIB of an SNMP and more than two objects are correlated to define a trap generation condition.

2. The method according to

claim 1

, wherein the TrapFlag field is a field for indicating whether a trap is to be generated for each object described in the MIB.

3. The method according to

claim 1

, wherein a value of the TrapFlag field is set as ‘

ON’

state or ‘

OFF’

state by the manager.

4. The method according to

claim 3

, wherein the agent generates a trap for a corresponding object in case that the TrapFlag field is in the ‘

ON’

state, while, the agent does not generate a trap in case that the TrapFlag field is in the ‘

OFF’

state.

5. The method according to

claim 1

, wherein the TrapPeer field is a field for defining a trap generation condition for an object.

6. The method according to

claim 5

, wherein the TrapPeer field is set as an ‘

ON’

state or an ‘

OFF’

state by the agent.

7. The method according to

claim 6

, wherein the agent sets the TrapPeer field as the ‘

ON’

state in case that the state of an object satisfies a trap generation condition.

8. The method according to

claim 7

, wherein the trap generaiton condition is defined by correlating more than two objects.

9. A method for controlling trap generation of an SNMP which is operated between a manager and at least one agent, comprising the steps of:

defining a TrapFlag field and a TrapPeer field in an MIB of an agent;

setting a TrapFlag field value according to the message outputted from the manager;

setting a TrapPeer field value for each object by the agent according to the Trap generation condition defined in the MIB; and

generating a trap for an object according to the values of the TrapFlag field and the TrapPeer field.

10. The method according to

claim 9

, wherein the TrapFlag field is a field for indicating whether a trap is to be generated for each object described in the MIB.

11. The method according to

claim 9

, wherein the TrapPeer field is a field for defining a trap generation condition for an object.

12. The method according to

claim 9

, wherein the agent sets the TrapPeer field as the ‘

ON’

state in case that the state of an object satisfies a trap generation condition.

13. The method according to

claim 9

, wherein the trap generation condition is defined by correlating more than two objects.

14. The method according to

claim 9

, wherein the trap generating step comprising the sub-steps of:

searching a TrapFlag field of each object when it comes to a trap generation period;

checking the state of a TrapPeer field in case that the TrapFlag is in an ‘

ON’

state; and

generating a trap for a corresponding object in case that the TrapPeer is in the ‘

ON’

state.

15. The method according to

claim 14

, wherein in case that the TrapFalg is in the ‘

OFF’

state, a trap is not generated in no case.

16. The method according to

claim 14

, wherein in case that the TrapFlag is in the ‘

ON’

state and the TrapPeer is in the ‘

OFF’

state, a trap is not generated.

17. A method for controlling trap generation of an SNMP comprising the steps of:

defining a TrapFlag field and a TrapPeer field in an MIB of an agent; and

generating a trap for an object according to the values of the TrapFlag field and the TrapPeer field as defined, of which

the step of generating a trap comprising the sub-steps of;

searching the TrapFlag field of each object when it comes to a trap generation period;

c

hecking a state of the TrapPeer field in case that the TrapFlag is in an ON state; and

generating a trap for a corresponding object in case that the TrapPeer is in an ON state.

18. The method according to

claim 17

, wherein the TrapFlag field is a field for indicating whether a trap is to be generated for each object described in the MIB.

19. The method according to

claim 17

, wherein the TrapPeer field is a field for defining a trap generation condition for an object.

20. The method according to

claim 17

, further comprising the steps of:

setting a TrapFlag field value according to a message outputted from the manager; and

setting a TrapPeer field value for each object in the agent according to the trap generation conditions defined in the MIB.

21. The method according to

claim 20

, wherein the manager outputs a message to set a TrapFlag field of an object of which state is not changed as an ‘

OFF’

state.

22. The method according to

claim 20

, wherein the trap generation condition is defined by correlating more than two objects.

23. The method according to

claim 20

, wherein the agent sets the TrapPeer field as the ‘

ON’

state in case that the state of an object satisfies a trap generation condition.
