Embodiment 1

[0112] Scenario limitation: VSU system connection diagram as shown in Figure 7 As shown, where the first device and the second device are located in the same broadcast domain, and the anti-loop protocol STP is enabled, the ports connecting the first device and the second device to the uplink device belong to the same Layer 3 VLAN, because the first device and the The second device belongs to the same VSU system, so the IP addresses corresponding to the Layer 3 VLAN ports of the two devices are the same. Assume that the IP addresses of the Layer 3 VLAN ports of the first device and the second device in the VSU system are 192.168.1.1, and the subnet mask 255.255.255.0, the uplink device is also configured with a layer-3 VLAN, the IP address is 192.168.1.2, and the subnet mask is 255.255.255.0. The root of the STP is not on the side of the first or second device, and the blocker port must be on the second A device or a second device side.

Embodiment 2

[0125] Scenario limitation: VSU system connection diagram as shown in Figure 7 As shown, the first device and the second device are located in different broadcast domains, and the ports connecting the first device and the second device to the uplink device are layer-3 routing ports. Assume that the IP address of the layer-3 routing port of the first device is 192.168.1.1, the subnet mask is 255.255.255.0, the IP address of the layer-3 routing port of the second device is 192.168.2.1, the subnet mask is 255.255.255.0, the layer-3 routing between the uplink device and the first device The IP of the interface is 192.168.1.2, and the IP of the layer-3 routing interface connecting the uplink device to the second device is 192.168.2.2.

[0126] In this scenario, if Figure 9 As shown, the dual-active device detection method in the VSU system provided by the embodiment of the present invention includes:

Abstract

The invention provides a double-main-device conflict detection method for a VSU system, and network equipment. The method comprises the steps: transmitting an ICMP request message to uplink equipment of the VSU system through a port of a preset type when first equipment determines that a VSL link of the VSU system is cut off, wherein the ICMP request message comprises the MAC address of the first equipment, and a main device vote parameter of the first equipment; receiving an ICMP response message transmitted by the uplink equipment; and carrying out double-main-device conflict detection according to the MAC address and main-device vote parameter of the first equipment and the MAC address and main-device vote parameter of the second equipment when the ICMP response message is determined to have the MAC address and main-device vote parameter of the second equipment. The method is good in network compatibility, can meet the demands of different scenes, does not need to build a dedicated link for the transmission of a detection message, and saves network resources.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for detecting the conflict of dual active equipment in a VSU system and network equipment. Background technique [0002] VSU (Virtual Switching Unit, Virtual Switching Unit) is a network system virtualization technology that supports combining multiple devices into a single virtual device. Access, aggregation, and core layer devices can all form VSUs to form an end-to-end VSU networking solution for the entire network. Compared with the traditional networking mode, this networking can simplify the network topology, reduce network management and maintenance costs, shorten application recovery time and service interruption time, and improve network resource utilization. [0003] The member devices in the VSU system form a logical entity through the internal VSL (Visual Switching Link, virtual switching link) link. At the same time, when the VSU system is est...
