Problems solved by technology

In addition, SNMP is based on UDP (User Datagram Protocol) and is connectionless, so it is easier for managers to lose traps, which greatly reduces the reliability of trap message delivery
[0004] In the network management system composed of managers and agents, this shortcoming of Trap has become a weak link of the network management system, reducing the availability and reliability of the fault management function of the network management system

Embodiment Construction

[0014] The core method of this embodiment is: by adding the keyword whether to confirm the Trap in the community name (community) carried by the Trap, after the manager receives the Trap, decide whether to check the keyword in the community name (community) string Confirm the trap. The confirmation method is that the manager notifies the agent that the Trap has been received by setting a specific variable on the agent.

[0015] The concrete implementation of technical scheme is described in further detail below:

[0016] 1) The agent modifies the construction method of the existing Trap community name (community)

[0017] On the NE where the SNMPv1 / v2c agent resides, it is necessary to modify the method of constructing the trap community name so that the community name becomes a compound community name, including the key word whether trap confirmation is required. For example, the new community name could be:

[0018] Actual community+'@eventId='+eventId+'@confirm'

Abstract

The invention discloses a Trap community name format based on simple network management protocol. The simple network management protocol is called SNMP for short thereinafter and is applicable to SNMP v1/v2c. The Trap community name format is as follows: the actual community + eventId+ '@confirm'. Among which eventId marks the Trap information number of the Trap information and '@confirm' is the keyword to decide whether the Trap information needs affirming. The Trap information community name format of the invention saves the cost of the network management system in improving alarming reliability and enhances Trap information receiving reliability.

Description

technical field [0001] The invention relates to a format of a Trap message community name in the SNMP v1 / v2c management framework, in particular to the field of alarm and message management of various devices with SNMP as the management interface. Background technique [0002] SNMP (Simple Network Management Protocol) is a management protocol based on UDP packets in network management, which is used for communication and management operations between SNMP Manager (hereinafter referred to as manager) and SNMP Agent (hereinafter referred to as agent). In the versions of SNMP v1 and v2c, the message that the agent actively sends to the manager is called Trap (trap). [0003] A notable feature of Trap is that the agent does not need the manager to return a confirmation message when sending a Trap. In addition, SNMP is based on UDP (User Datagram Protocol) and is connectionless, so it is easier for managers to lose traps, which greatly reduces the reliability of trap messages. ...
