Embodiment Construction

[0058] A switch stacking system, a slave device, a switch chip and a method for processing protocol packets provided by the present invention will be described in more detail below with reference to the drawings and embodiments.

[0059] Such as figure 2 As shown, the embodiment of the present invention provides a switch chip 20, which is applied to a slave device of a switch stack system, including an encapsulation (ENCAP) module 21 and a stack port 22;

[0060] ENCAP Module 21 for:

[0061] Encapsulate the remote processor (RemoteCPU, RCPU) header for the received protocol message to be processed by the CPU of the main device in the stacking system; the RCPU header includes the Layer 2 Ethernet protocol L2 header and the protocol message originally sent Data Center Bridge (DCB) information of the CPU of the master device; among them, the L2 header includes the destination MAC address used internally and the MAC address of the CPU of the slave device; the DCB information in...

Abstract

The embodiment of the invention discloses a switch stacking system, a slave device, a switch chip and a method for processing protocol messages. In this solution, the ENCAP module in the switch chip is used alone to encapsulate the protocol packets processed by the CPU of the master device. Compared with the encapsulation of the CPU forwarded to the slave device in the prior art, not only It takes less time and simplifies the forwarding process. Only using the switch chip for hardware forwarding speed is faster, which greatly improves the stacking system protocol convergence time, improves the processing efficiency of protocol packets, and reduces the protocol switching process. the number of lost packets. In addition, the DCB information of the protocol message originally sent to the CPU of the master device is encapsulated in the RCPU header at one time, so that the information sent to the CPU of the master device in the protocol message received from the device can be communicated with the switch under the agreement The information sent to the single-machine CPU in the message is consistent.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a switch stacking system, a slave device, a switch chip and a method for processing protocol messages. Background technique [0002] With the rapid development of information technology and the rapid expansion of the network scale, the number of switch interfaces planned in the previous network is not enough to meet the needs of network applications. At this time, the switch stacking technology emerges as the times require. The switch stacking technology uses stacking cables to connect several fixed switches together to increase the port density and bandwidth of the switch, and realize high-speed interconnection and unified management of the switches. Logically speaking, they belong to the same device, as long as you log in to Any one of the switches can manage and configure all the switches in the stack, which is very convenient for users, just like managing a stan...
