The following describes in detail the technical solution proposed in the embodiments of the present application through the accompanying drawings.
Fig. 1 is a flowchart of a method for detecting a dual-master device in an MLAG environment according to an embodiment of the present application. As shown in fig. 1, the method for detecting the dual-master device in the MLAG environment includes the following steps:
s101, under the condition that a peerlink link between a main device and a standby device is disconnected in an MLAG environment, the main device performs fault detection on a main port, and under the condition that the main port is determined to be in a normal running state, a health loop detection message is sent to a first transmission node through the main port at regular time.
In an embodiment of the present application, fig. 2 is a schematic diagram of a method for detecting dual main devices in a normal state according to an embodiment of the present application. As shown in FIG. 2, switches A and B construct an MLAG environment through a Peerlink link, A is an MLAG main device and an EAPS ring network master main node, B is an MLAG standby device, and devices C and D are EAPS ring network transmission nodes.
Further, the MLAG member ports AGG1 of the MLAG device a and the MLAG device B together form a cross-device link aggregation group AGG1 with the aggregation port AGG1 of the transmission node C, the MLAG member ports AGG2 thereof together form a cross-device link aggregation group AGG2 with the aggregation port AGG2 of the transmission node D, and the MLAG member ports AGG3 thereof together form a cross-device link aggregation group AGG3 with the AGG3 of the Server device. The uplink ports AGG1 and AGG2 of the switch A and the switch B are accessed into a common Ethernet in the form of MLAG member ports and run EAPS Ethernet ring network protocol, and AGG3 is set as a three-layer network interface. The switches A, C and D operate EAPS ring network protocol, the MLAG standby equipment B synchronously transmits all received EAPS protocol messages to the MLAG main equipment A through a peerlink port, the main equipment A is responsible for operating EAPS ring network protocol, the standby equipment B does not participate in EAPS ring network protocol operation, and the MLAG main equipment A and the standby equipment B logically belong to the same EAPS ring network master main equipment in the aspects of the transmission nodes C and D.
As shown in fig. 2, under normal conditions, the EAPS ring network master a sends a health loop detection message from the primary port AGG1 at regular time, and the transmission node C, that is, the first transmission node, receives the health message from the ring network secondary port AGG1 and forwards the message from the other ring network master port 3. The transmission node D is a second transmission node, receives the health message from the ring network auxiliary port 3, and forwards the message from the other ring network main port AGG 2. The MLAG standby equipment B synchronizes the received health message to the same MLAG member port of the master equipment A for calculation, if the auxiliary port AGG2 of the master main equipment A receives the health message, the EAPS ring network loop detection is successful, and the master main equipment A sets the auxiliary port AGG2 of the master main equipment A to be in a blocking state.
In one embodiment of the present application, the master device detects a peerlink link disconnection condition. If the peerlink link of the MLAG is disconnected, the MLAG dual-master detection function is started. If the peerlink link of the MLAG is recovered from failure, the MLAG dual-master detection function is closed, and the MLAG standby equipment B does not execute any action even if receiving a health loop detection message.
Further, the master device performs fault detection on the master port, and under the condition that the master port is determined to have no fault, the EAPS ring master device a immediately sends a health loop detection message from the master port AGG 1.

In one embodiment of the present application, the first transmission node sends the health loop detection message to the second transmission node through the output ring network main port when determining that the output port corresponding to the aggregation port is in the failure state.
Specifically, the directions indicated by arrows in fig. 2 can be regarded as MLAG dual-main detection channels, any channel has a link failure, and other link channels still exist to forward the health message to the MLAG standby device B, so that the MLAG dual-main detection function can be continuously effective. For example, in fig. 2, the member port 2 of the aggregation port AGG1 of the transmission node C fails to be disconnected, at this time, the health message received by the member port 1 of AGG1 is forwarded from the other ring main port 3, and if the ring main port 3 of the transmission node D receives the health message, the health message is forwarded from the member ports 1 and 2 of the ring main port AGG2 at the same time, the MLAG standby device B can still receive the health message, and the MLAG dual-main detection function can continue to be effective.
S103, the second transmission node sends the received health loop detection message to the main equipment and the standby equipment.
And the second transmission node sends the health loop detection message to the main equipment through a first output port corresponding to the second aggregation port. And the second transmission node sends the health loop detection message to the standby equipment through a second output port corresponding to a second aggregation port.
Specifically, as shown in fig. 2, the transmission node D, that is, the secondary port 3 of the second transmission node, receives the health message, and forwards the message from the two member ports 1 and 2 of the aggregation port AGG2 at the same time.
And S104, under the condition that the standby equipment receives the health loop detection message sent by the first transmission node and/or receives the health loop detection message sent by the second transmission node, the standby equipment disconnects other service ports except the peerlink port so as to finish double-main equipment detection in the MLAG environment.
In one embodiment of the present application, as shown in fig. 2, when the aggregation port AGG1 or AGG2 of the MLAG backup device B receives the health message, the MLAG dual-master detection is successful, and the backup device B disconnects all its service ports except for the peerlink port. To complete the dual master detection in the MLAG environment.
In one embodiment of the present application, the master device sends a health loop detection message to the second transmission node at regular time through the secondary port if it is determined that the primary port has a fault. And the second transmission node sends the received health loop detection message to the standby equipment and the first transmission node so as to finish the detection of the double main equipment in the MLAG environment.
Specifically, the second transmission node sends the received health loop detection message to the standby equipment and the first transmission node. And the first node sends the health loop detection message to the standby equipment after receiving the health loop detection message. And under the condition that the standby equipment receives the health loop detection message, the double-master equipment detection under the MLAG environment is completed.
Further, the second transmission node sends the health loop detection message to the main equipment through the output port of the second aggregation port; and the second transmission node sends the health loop detection message to the first transmission node through the corresponding ring network auxiliary port.
Further, if the port of the primary port AGG1 of the primary device fails to disconnect, the master primary device immediately sends a health detection message from the secondary port AGG 2. Fig. 3 is a schematic diagram of a dual-master device detection method in a fault state provided in this embodiment of the present application, as shown in fig. 3, a member port 1 of an aggregation port AGG2 of a transmission node D receives the health message, forwards the message from another member port 2 of the aggregation port AGG2, and forwards the message from another ring main port 3 at the same time, a ring main port 3 of the transmission node C receives the health message, forwards the message from 2 member ports 1 and 2 of another ring main port AGG1 (only the member port 2 forwards the message due to the fault disconnection of the member port 1), and an aggregation port AGG1 or AGG2 of an MLAG standby device B receives the health message, so that the dual-master detection of the MLAG is successful.
Further, in fig. 3, the directions indicated by arrows can be regarded as MLAG dual-main detection channels, and if any channel has a link failure, other link channels still exist to forward the health message to the MLAG standby device B, so as to ensure that the MLAG dual-main detection function can be continuously effective.
In one embodiment of the present application, the master device performs fault detection on the master port in real time. And under the condition that the main port is determined to be in a normal running state, the main equipment stops sending the health loop detection message to the second transmission node through the auxiliary port, and sends the health loop detection message to the first transmission node through the main port.
Specifically, if the master main device port AGG1 fails to recover, the master main device secondary port AGG2 immediately stops sending the health detection message, and the master port AGG1 immediately sends the health detection message.
According to the embodiment of the application, the MLAG double-main detection function is realized through the working mechanism of the EAPS protocol, the ring network link is used as a keepalive double-main detection channel, and the health ring network detection message is used as a keepalive double-main detection message.

In addition, the EAPS ring network is provided with a plurality of double-main detection channels, so that the stability of the double-main detection function is effectively ensured, and the condition that the whole double-main detection function fails due to the failure of one double-main detection link is avoided.
