Abstract

The invention provides an improved bidirectional SNMP alarm method and device, and the method comprises the following steps: S1, binding the connection between a single-deice SNMP channel and multipledevices, and enabling the multiple devices to monitor an SNMP message; S2, after the single device generates an alarm, generating an alarm SNMP message, and sending the alarm SNMP message to multipledevices; S3, after the multiple devices receive the alarm SNMP message, storing the alarm SNMP message in a database, generating an alarm reply message, and returning the alarm reply message to the single device; S4, after the single device sends an alarm SNMP message to the multiple devices, determining whether the alarm SNMP message is repeatedly sent to the multiple devices according to whether an alarm reply message of the single device is received within an appointed time period; and S5, unbinding the connection between the SNMP channel of the single device and the multiple devices, andstopping monitoring the SNMP message by the multiple devices.

Example Embodiment

[0076] Example 1:
[0077] Such as figure 1 As shown, the present invention provides an improved two-way SNMP alarm method, including the following steps:
[0078] S1. Bind the connection of a single device SNMP channel with multiple devices, and multiple devices monitor SNMP messages;
[0079] S2. After a single device generates an alarm, it generates an alarm SNMP message and sends it to multiple devices;
[0080] S3. After multiple devices receive the alarm SNMP message, they store the alarm SNMP message in the database, generate an alarm reply message, and return it to a single device;
[0081] S4. After a single device sends an alarm SNMP message to multiple devices, it determines whether to repeatedly send an alarm SNMP message to multiple devices according to whether a single device's alarm response message is received within the agreed time period;
[0082] S5. Unbind the connection between the SNMP channel of a single device and multiple devices, and the multiple devices stop monitoring SNMP messages.

Example Embodiment

[0083] Example 2:
[0084] Such as figure 2 As shown, the present invention provides an improved two-way SNMP alarm method, including the following steps:
[0085] S1. Bind the connection of a single device SNMP channel with multiple devices, and multiple devices will monitor SNMP messages; the specific steps are as follows:
[0086] S11. A multi-device connection message is sent to multiple devices, the connection message includes a multi-device ID, a multi-device IP address, a multi-device port, and a single-device IP address;
[0087] S12. A single device receives the connection message, and binds the SNMP channel according to the multi-device ID in the connection message;
[0088] S13. Multiple devices monitor the SNMP message of a single device;
[0089] S2. After a single device generates an alarm, it generates an alarm SNMP message and sends it to multiple devices;
[0090] S3. After multiple devices receive the alarm SNMP message, they store the alarm SNMP message in the database, and generate an alarm reply message, which is returned to a single device; the alarm reply message includes multiple device IDs and alarm IDs;
[0091] S4. After a single device sends an alarm SNMP message to multiple devices, it determines whether to repeatedly send an alarm SNMP message to multiple devices according to whether a single device's alarm response message is received within the agreed time period; the specific steps are as follows:
[0092] S41. After a single device sends an alarm SNMP message to multiple devices, it is determined whether a single device's alarm reply message is received within the agreed time period;
[0093] If yes, go to step S42;
[0094] If not, go to step S43;
[0095] S42. The single device marks the sent alarm SNMP message as read, and then goes to step S5;
[0096] S43. A single device repeatedly sends an alarm SNMP message to multiple devices according to the type of the alarm SNMP message according to the corresponding retransmission waiting time; the types of the alarm SNMP message include emergency, important, warning, and message; corresponding emergency types of alarms The retransmission waiting time of SNMP messages is 30s, the retransmission waiting time of corresponding important types of alarm SNMP messages is 2min, the retransmission waiting time of corresponding warning SNMP messages is 2min, and the corresponding message type alarm SNMP messages The retransmission waiting time of the document is 5 minutes;
[0097] S5. Unbind the connection between the SNMP channel of a single device and multiple devices, and the multiple devices stop monitoring SNMP messages; the specific steps are as follows:
[0098] S51. Multiple devices determine whether to continue receiving alarm SNMP messages;
[0099] If yes, return to step S2;
[0100] If not, go to step S52;
[0101] S52. Multiple devices generate a destruction message and send it to a single device;
[0102] S53. After a single device receives the destruction message, it unbinds the multi-device ID from the SNMP channel.
[0103] In the foregoing embodiment 2, before step S2, the following steps are further included:
[0104] SS2. When multiple devices are deployed later than a single device or multiple devices fail to receive an alarm SNMP message normally after the set time period is shut down, multiple devices will generate an alarm retransmission message and send it to a single device;
[0105] SS3. After a single device receives an alarm retransmission message, it repeatedly sends an alarm SNMP message to multiple devices; the alarm retransmission message includes the multi-device ID, retransmission method, retransmission quantity, retransmission start time and retransmission termination time ; Retransmission methods include retransmission by time interval and retransmission by quantity;
[0106] Step SS3 specific steps are as follows:
[0107] SS31. After a single device receives the alarm retransmission message, it judges the retransmission mode;
[0108] If it is retransmitted according to the time interval, go to step SS32;
[0109] If it is to resend according to the quantity, go to step SS33;
[0110] SS32. A single device screens the alarm SNMP messages according to the number of retransmissions, filters out the number of alarm SNMP messages equal to the number of retransmissions before the current time node, and sends them to multiple devices repeatedly, ending;
[0111] SS33. A single device screens the alarm SNMP messages according to the time interval, filters out all the number of alarm SNMP messages between the retransmission start time and the retransmission end time, and sends them to multiple devices repeatedly.
