Problems solved by technology

[0011] For a normal working extended bridge system, when the link layer discovery protocol (Link Layer Discovery Protocol, LLDP) is used to discover that the neighbors connected to the cascading port have changed, the CB reclaims the allocated resources, and all BEP ports generated under the cascading port are deleted. , the configuration information on the BEP port will also disappear, and manual configuration is required, which takes a long time to restore and the configuration is cumbersome

Abstract

The invention discloses a method, device, equipment and storage medium for quickly recovering an extended bridge system, and relates to the field of communication technology. The method includes: monitoring the uplink port of a primary PE device cascaded with a CB device in the extended bridge system change; if it is detected that the uplink port of the first-level PE device cascaded with the CB device is transferred from the original uplink port to a new uplink port, then keep the extension on the CB device as the first-level PE device the virtual interface resource allocated by the port; reclaim the virtual interface resource previously allocated to the new uplink port on the CB device, and allocate the virtual interface resource for the original uplink port on the CB device. The embodiment of the present invention can quickly restore the extended bridge system without reconfiguring services.

Description

technical field [0001] The present invention relates to a bridge port extension (Bridge PortExtension, BPE) protocol in the IEEE802.1BR standard in the communication technology field, and in particular to a method, device, device and storage medium for quickly restoring an extended bridge system. Background technique [0002] Currently, with the rapid development of cloud computing and data center virtualization technologies, the number of virtual machines is increasing exponentially. The traffic transmission between virtual machines (Virtual Machines, VMs) inside physical devices and between VMs and external networks must be transmitted through physical It is realized by a virtual switch (Virtual Switch, vSwitch) inside the device, which brings great challenges to the network management of the virtual machine. [0003] In order to simplify the management of the data center system and hand over complex management and policy control to the switch devices in the network, IEEE ...
