Embodiment 1

[0034] Since the problem of message loss will only occur when the data communication device at one end detects the state change of the physical port through polling, it is assumed in this embodiment that the data communication device at the opposite end detects the state change of the physical port through polling, as follows Take the local data communication device as an example to detect the status change of the physical port through polling, see figure 2 The method for configuring an Ethernet link aggregation port provided in this embodiment specifically includes:

[0035] 101: Detect the state changes of the physical ports sequentially, and judge whether each physical port has been detected, that is, whether a polling is completed, and if so, go to step 104; otherwise, go to step 102.

[0036] 102: Detect the next physical port.

[0037] 103: Determine whether the state of the physical port has changed, if yes, execute 105; otherwise, return 101.

[0038] 104: Interval ...

Embodiment 2

[0050] see image 3 , the embodiment of the present invention provides a kind of equipment, this equipment comprises:

[0051] a determining module, configured to determine a state change of a physical port of the device;

[0052] The judging module is used for judging whether the physical port is a port bound to the Ethernet link aggregation port after the determining module determines that a state change occurs on the physical port and whether the state changes from a blocked state to an open state;

[0053] The configuration module is used to configure the sending and receiving state of the physical port to receive only when the judging module judges that the physical port is a port bound to the Ethernet link aggregation port and the state change of the physical port changes from a blocking state to an open state In the message non-transmitting state, after a certain period of time, the sending and receiving state of the physical port is configured as a normal forwarding s...

Abstract

The invention discloses a method and a device for configuring an Ethernet trunk aggregation port belonging to the data communication field. The method comprises the following steps: determining the state change of a physical port; judging whether the physical port is the port bound by the Ethernet trunk aggregation port and whether the state is changed from a blocking state to an opened state; and if the physical port is the port bound by the Ethernet trunk aggregation port, the receiving and sending state of the physical port is configured into the state of only receiving a message and not sending a message; and the receiving and sending state of the physical port is configured into a normal forwarding state after a period of time. The device comprises a determination module, a judgment module and a configuration module. After the invention judges that the state of the physical port bound by the Eth-Trunk is changed from Down to UP, the message loss of Eth-Trunk member ports under the UP state is effectively prevented through configuring the state of the physical port into the state of only receiving the message and not sending the message state.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and equipment for configuring Ethernet link aggregation ports. Background technique [0002] Eth-Trunk (Ethernet Trunk, Ethernet Link Aggregation) technology is used by bundling multiple Ethernet physical ports into one logical port. Data communication devices, such as Ethernet switches and routers, can use Trunk technology to improve network bandwidth, load sharing and service protection. [0003] Because the Eth-Trunk port is a logical port and does not carry real packet forwarding, the traffic of this logical port still needs to be forwarded to a certain physical port bound to it according to a certain mechanism (such as hash). In this case, if the states of the Eth-Trunk member ports at both ends of the link are inconsistent, packets will be lost. [0004] In the prior art, a data communication device generally uses the following two methods to detect a state chan...
