Power grid process switch and configuration method

Abstract

The invention provides a power grid process switch and a configuration method. The power grid process layer switch comprises a CPU, a switch chip and an extended switch chip, wherein the CPU is respectively connected with the switch chip and the extended switch chip, the switch chip is provided with a plurality of service ports, the extended switch chip is provided with a plurality of MMS ports, and the plurality of MMS ports achieve mutual isolation of data through a VLAN method. The beneficial effects are that the power grid switch needs a plurality of MMS ports, the isolation between the MMS ports and common service port of the switch is physically isolated, the plurality of MMS ports can be realized through the extended switch chip, and the data isolation between the MMS ports is realized by utilizing the VLAN technology, so that the power grid data network security is realized.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a power grid process switch and a configuration method. Background technique [0002] At present, some switches in the smart grid support the IEC61850 protocol, but most of the 61850 protocol data and remote management data are managed through the out-of-band port of the CPU or the common service port of the switch. [0003] The disadvantages of the above two methods are: Method 1: Management data and switch data can be physically isolated through CPU out-of-band port management, but the number of CPU out-of-band ports on the market is often only one, which cannot satisfy simultaneous access from different network segments. Method 2: The common service port of the switch is used for management, which can realize multiple ports and multiple network segments, but the physical isolation of the service port and the management port cannot be achieved. Remote data may affect the data ...

[0003] The disadvantages of the above two methods are: Method 1: Management data and switch data can be physically isolated through CPU out-of-band port management, but the number of CPU out-of-band ports on the market is often only one, which cannot satisfy simultaneous access from different network segments

Method 2: The common service port of the switch is used for management, which can realize multiple ports and multiple network segments, but the physical isolation of the service port and the management port cannot be achieved. Remote data may affect the data of the service port of the switch itself, and there are hidden dangers in network security.
