Description
Technical field
The invention belongs to power communication system, the monitoring method of switch-spanning in particular to a kind of intelligent substation.
Background technology
With the gradually application of IEC61850, current automatic system of intelligent transformer station is generally divided into station level, interval
Layer and process layer.Process layer mainly completes the sampling of analog quantity, On-off signal output, transmission of operation control command etc. and one
The relevant function of secondary device, the real time data of wall aggregation process layer receive the order of station level and are sent to process layer and ordered
It enables.
Station level is the supervision and management center of whole station, provides man-machine interface, realizes that the management to wall controls, and pass through
Electric power data network is communicated with control centre or centralized control center.In the case of net at three layer two, process-level network transmits goose and SV
Message, and station level network transmission goose and MMS message.In order to ensure the correctness of data, and complete documentation data, usually
The station level of intelligent substation by Network Analyzer come the message of monitoring station control layer network, only supervise by the general method for using mirror image
Data on interchanger on the same stage are controlled, and for the method that the monitoring of the data in cascaded switches has rarely had, it should consider data
Integrality, again consider data uniqueness.Mirror image by configuring interchanger can be to the message that is linked on interchanger
It is copied, identical message can be exported on the destination interface of mirror image, for multicast message, if do not had on Ethernet switch
Have and configure this multicast, the mapping relations of this multicast address and port are can not find in address table, multicast is understood after entering interchanger to each
Each port floods in a same VLAN.If this multicast is mirrored to destination interface again, monitoring host computer will receive weight
Multiple message.
Invention content
In view of the deficiencies of the prior art, the present invention proposes a kind of station level switch-spanning data monitoring side of intelligent substation
Method, intelligent substation station level network data are mainly made of goose and MMS messages, same usually using Network Analyzer monitoring
Data on platform interchanger, but Network Analyzer and smart machine be not on same interchanger in some cases, in order to monitor
The message that all devices on to distant-end switch are sent out, and not will receive the message of repetition, using the grade to distant-end switch
The method for joining mouth configuration mirroring and dividing VLAN, and the input traffic of the cascade port of interchanger where monitoring host computer is mirrored to
This monitoring host computer, the cascade port are divided in a VLAN, and monitoring host computer are divided into another VLAN, monitor in this way
Host can completely monitor all messages in cascaded switches, and will not repeat.
The purpose of the present invention is what is realized using following technical proposals：
The monitoring method of switch-spanning in a kind of intelligent substation, it is improved in that the method includes：
（1）The VLAN of the cascade port port_b of switch b is set；
（2）The VLAN of other ports on switch b is set；
（3）The mirror image of other ports on switch b is set；
（4）The monitoring port VLAN ID of switch A are set；
（5）The cascade port port_a that switch A is arranged is another VLAN ID；
（6）The mirror image of port_a is set.
Preferably, the step（1）Including one VLAN of establishment on switch b, port_b is added in this VLAN, if
It is ACCESS to set pattern of this port in this VLAN, or is untagged types, makes all outgoing messages without VLAN
Label.
Preferably, the step（2）Include being set as all of the port on switch b in addition to cascading port port_b in addition
One VLAN.
Preferably, the step（3）By the input data mirror of all of the port on switch b in addition to cascading port port_b
As to cascade port, mirror image pattern is input flow rate monitoring mode, destination interface port_b.
Preferably, the step（6）The mirror image of cascade port port_a including setting switch A, pattern is inlet flow
Monitoring mode is measured, destination interface is port where monitoring host computer.
Preferably, interchanger where the Network Analyzer, that is, monitoring host computer is A, and the interchanger to be monitored is B, cascade
Port is respectively port_a and port_b.
Preferably, the method includes cascading more interchangers, similar setting can be done.
Compared with the prior art, beneficial effects of the present invention are：
1, the present invention can effectively realize monitoring of the intelligent substation station level to switch-spanning network message, both can be with
Smart machine sends all network messages on effective monitoring distant-end switch, and not will receive the message of repetition, thus may be used
To realize the monitoring to various types of message all standings.
2, the present invention uses the mirror image and VLAN configuration features of Ethernet switch, can simply and effectively realize monitoring master
Machine monitors the network data on distant-end switch, and whole process is simple and convenient, just only by the configuration to interchanger
Data monitoring can be achieved, do not need every interchanger and configure a monitoring host computer, save system Construction cost
3, design scheme of the invention, is extended to across Duo Tai the case where being not limited solely to two switch concatenations
The case where switch network.Effective record to network message in substation may be implemented, it is logical to reappear equipment room network at that time
The overall process of letter carries out accident analysis for operation maintenance personnel and provides effective method.
Description of the drawings
Fig. 1 is the monitoring schematic diagram of switch-spanning in a kind of intelligent substation provided by the invention.
Fig. 2 is the monitoring method flow chart of switch-spanning in a kind of intelligent substation provided by the invention.
Specific implementation mode
The specific implementation mode of the present invention is described in further detail below in conjunction with the accompanying drawings.

802.1Q label will be removed.It checks that VLAN shows information after the completion of configuration, configuration is preserved after confirmation is errorless.
2, a VLAN, ID number B are created on switch b, A and B are differed herein, and be monitored device on switch b
The switch port connected is added in this VLAN, and it is ACCESS, Huo Zhewei that pattern of these ports in this VLAN, which is arranged,
Untagged types so that after monitoring port output, 802.1Q labels will be removed the data in VLAN.It is checked after the completion of configuration
VLAN shows information, confirms that errorless rear preserve configures.
3, Port Mirroring is configured on switch b, source port is by all monitored devices on switch b even interchanger
Port, destination interface port_b, mirror image pattern are set as input flow rate monitoring mode.Mirror Info is checked after the completion of configuration,
Confirm that errorless rear preserve configures.
4, a VLAN is created on switch A, monitoring host computer is added in this VLAN by ID number C, this port is arranged
Pattern in this VLAN is ACCESS, or is untagged types so that after the data in VLAN are exported from this port,
802.1Q label will be removed.It checks that VLAN shows information after the completion of configuration, configuration is preserved after confirmation is errorless.
5, a VLAN is created on switch A, ID number D, D is different from C, and port_a is added in this VLAN, setting
Pattern of this port in this VLAN is ACCESS, or is untagged types so that data in VLAN are from this port
After output, 802.1Q labels will be removed.It checks that VLAN shows information after the completion of configuration, configuration is preserved after confirmation is errorless.
6, Port Mirroring, source port port_a are configured on switch b, destination interface is port where monitoring host computer,
Mirror image pattern is set as input flow rate monitoring mode.Mirror Info is checked after the completion of configuration, confirms errorless rear preservation configuration.
If 7, cascading more interchangers, by the cascade port of the data image of distant-end switch to interchanger, final mirror image
Onto monitoring device, prevent Data duplication from copying by dividing VLAN in the process.
Embodiment
