Embodiment 1

[0049] Embodiment 1 describes in detail a method for detecting and suppressing an Ethernet link storm proposed by this application.

[0050] refer to figure 1 , which shows a flowchart of a method for detecting and suppressing an Ethernet link storm according to Embodiment 1 of the present application.

[0051] Step 11, setting the forwarding rate threshold value of each forwarding port according to the maximum bandwidth of each forwarding port in the switch chip;

[0052] During broadcast storms, the forwarding rate of data packets in the Ethernet link is much higher than that of transmitting normal business data, so the forwarding rate threshold can be set for each forwarding port according to the maximum bandwidth of each forwarding port in the switch chip to ensure The forwarding rate of each forwarding port under normal service will not reach the forwarding rate threshold.

[0053] For example, the maximum bandwidth of forwarding port A is 1000 Mbps, and the maximum ban...

Embodiment 2

[0068] Embodiment 2 introduces in detail a method for detecting and suppressing an Ethernet link storm proposed by this application.

[0069] refer to figure 2 , which shows a flowchart of a method for detecting and suppressing an Ethernet link storm described in Embodiment 2 of the present application.

[0070] Step 21, setting the forwarding rate threshold value of each forwarding port according to the maximum bandwidth of each forwarding port in the switch chip;

[0071] According to the maximum bandwidth of each forwarding port in the switch chip, a forwarding rate threshold is set for each forwarding port to ensure that the forwarding rate of each forwarding port will not reach the forwarding rate threshold under normal service.

[0072] Set the forwarding rate threshold value of each forwarding port in the switch chip to half of the maximum bandwidth of each forwarding port.

[0073] Since the packet forwarding rate of the Ethernet link during a broadcast storm is clo...

Embodiment 3

[0102] In the third embodiment, a method for detecting and suppressing an Ethernet link storm proposed in this application is introduced in detail.

[0103] refer to Figure 5 , which shows a flowchart of a method for detecting and suppressing an Ethernet link storm described in Embodiment 3 of the present application.

[0104] Step 31, setting the forwarding rate threshold value of the forwarding port;

[0105] Set the forwarding rate threshold of forwarding port A to 500 Mbps.

[0106] Step 32, detecting the forwarding rate of the forwarding port;

[0107] It is detected that the forwarding rate of forwarding port A at time T6 is 600 Mbps; the forwarding rate at time T7 is 300 Mbps.

[0108] Step 33, judging whether the forwarding rate exceeds the forwarding rate threshold;

[0109] Judging that the forwarding rate of forwarding port A of 600 Mbps at time T6 exceeds its forwarding rate threshold of 500 Mbps; judging that the forwarding rate of forwarding port A of 300 Mbps...

Abstract

The invention provides a method and device for detecting and inhibiting an Ethernet link storm in order to solve the problem that the prior art does not meet the demand of an external environment. The invention provides the method and device for detecting and inhibiting the Ethernet link storm in a design scheme of executing dynamic allocation on an Ethernet module. The method comprises the following steps of: setting a transfer rate threshold value of each transfer port according to the maximal bandwidth of each transfer port in an exchanging chip; detecting the transfer rate of each transfer port; and judging whether the transfer rate is equal to or more than the transfer rate threshold value of the corresponding transfer port, if so, turning off the transfer port. The storm is inhibited via dynamically switching on / off an Ethernet link in the method, so that the configuration of the Ethernet link is more flexible; in addition, the network address for remotely logging a base station is statically bonded with the port of the exchanging chip so that the base station can be remotely logged when the storm is broadcast, in this way, operations such as positioning problems, adjusting software configuration and extracting base station information are performed conveniently.

Description

technical field [0001] The present application relates to the technical field of communications, in particular to a method and device for detecting and suppressing an Ethernet link storm. Background technique [0002] The Ethernet link in the base station is responsible for realizing the data transmission between the boards and the data link layer inside the board, so as to ensure the communication between the base stations and the network layer between the base station and the personal computer (PersonalComputer, PC). Furthermore, various tools on the PC side can maintain, manage and debug the base station, such as updating the version of the base station, deploying cell parameters, and other operations. [0003] The key of the Ethernet link is the Ethernet switching chip on each board, which is connected to each processor of the base station, and can realize Layer 2 forwarding, forwarding the Ethernet packet from the source Medium Access Control (MAC) address to the destin...
