Description

Port fault processing method and device
Technical Field
The present invention relates to the field of network communication technologies, and in particular, to a method and an apparatus for processing a port fault.
Background
An IRF (Intelligent Resilient Framework) system connects a plurality of devices together, and after configuration, virtualizes the devices into one device.
In the star-type IRF system, as shown in fig. 1, each member device may be connected together through a two-layer network to form an IRF link, and may transmit a data packet and an IRF protocol packet at the same time without requiring direct connection of a physical line, where the IRF protocol packet may be a heartbeat packet.
In practical applications, a large amount of data traffic may pass through the IRF links between the member devices in the star-type IRF system, and in order to increase the bandwidth of the IRF links, the member devices are usually connected together through a two-layer network by using a plurality of physical ports (i.e., IRF ports) to form a plurality of available IRF links (e.g., 3 IRF links shown in fig. 2).
In order to load data traffic on each IRF link evenly, a hash algorithm is generally used to share all packets (IRF protocol packets and data packets) on each link. The implementation method has no problem under the condition that the whole network is normal, that is, the star-type IRF system can normally operate, and the message can also be normally forwarded, but if a fault occurs on a certain IRF link (the fault can include the situations that a port is disconnected, the two-layer network part is not communicated and the like), the situation that member equipment at one end of the IRF link considers that the IRF link is intact and continuously sends the message through the IRF link, and member equipment at the other end cannot receive the message due to the fault can occur, so that a large number of messages are discarded, further the IRF link in the IRF system is split, and a large number of services (services communicated through the split IRF link) are not communicated.
As shown in fig. 3, device B-IRF2 has failed to Port2/1 of the two-layer network, but Port1/1 of device a-IRF1 and Port3/1 of device C-IRF3 are still normal, so device a-IRF1 will still send part of the packet from Port1/1 to device B-IRF2, device C-IRF3 will still send part of the packet from Port3/1 to device B-IRF2, and Port2/1 of device B-IRF2 has failed, so that the packets sent by Port1/1 or Port3/1 cannot be received, and these packets will be discarded in the IRF link. This may directly result in the IRF link in the IRF system being split and a large amount of traffic (traffic communicated over the split IRF link) being unavailable.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a port fault processing method and device, which are used for avoiding message loss on a fault link caused by port faults of member equipment and further reducing the condition of IRF link splitting.
First, a port failure processing method provided in an embodiment of the present invention is described below.
It should be noted that, if a link failure (for example, a port failure) occurs during the setup of the multi-link star IRF system, a network administrator may remove and solve the occurred failure at the first time, so that the significance of the failure solution during the setup of the IRF system is not great. The ports mentioned in the embodiments of the present invention are all IRF ports. The method for establishing the IRF system is substantially the same as that in the prior art, and is not described herein.
Specifically, the port failure processing method provided in the embodiment of the present invention may be applied to any member device of an IRF system, and as shown in fig. 4, the method may include the following steps:
s401: and when the first heartbeat message is not received through any IRF port of the member equipment within the preset time, determining that the port has a fault.
In this step, the predetermined duration may be set according to a sending frequency of the member device sending the first heartbeat packet.
S402: and setting the working state of the port from the initial valid state to the invalid state.
In the step, the IRF port in the effective state allows to send a first heartbeat message and a data message; the IRF port in the invalid state is only allowed to send the first heartbeat message.
In the invention, after the IRF system is successfully established, the working state of each IRF port of the member equipment is set to be an effective state by default, valid marks can be used, the member equipment can send data messages through the set IRF port in the effective state, and also can send first heartbeat messages to neighbor equipment through the set IRF port in the effective state at a certain sending frequency so as to detect the connection condition of links between the member equipment. The first heartbeat message may be a Hello message. Subsequently, the second heartbeat message, the third heartbeat message, the fourth heartbeat message, the fifth heartbeat message and the sixth heartbeat message may be Hello messages.
It should be noted that, after it is determined that the port fails, the working state of the port is set from the initial valid state to the invalid state, which is mainly for subsequently enabling the neighbor device to send only the first heartbeat packet, so that the neighbor device maintains the neighbor relationship with the non-failed member device, and does not send the data packet any more, thereby reducing the packet loss. Wherein the invalid state may use an invalid flag.
S403: and when the member device is a slave member device and the port is a master port, selecting one port which meets the first preset screening rule from other IRF ports of the member device.
In this step, the main port is set by the member device after receiving, through the port, a second heartbeat message that notifies that the port corresponding to the port on the main member device is the main port for maintaining the stability of the IRF system, where the second heartbeat message is sent by the main member device, and sets other IRF ports as slave ports.
In the present invention, after the main member device is elected, the main member device selects an IRF port with the highest priority from all IRF ports of the main member device (for example, the port number is smaller and the priority is higher), and sets the IRF port as a main port, sets other IRF ports as slave ports, and subsequently uses the main port to maintain the stability of the IRF system. In addition, the master member device may also notify all the neighbor devices of the set identity information of the master port through a Hello message (i.e., a second heartbeat message), so that after all the neighbor devices receive the Hello message, the port corresponding to the master port of the master member device is set as the master port, and other IRF ports are set as slave ports. Of course, to facilitate distinguishing between master and slave ports, different flag bits may be used for marking.
It should be noted that the stability of the IRF system of the present invention is maintained by the main port of each member device, that is, each member device only uses the first heartbeat packet received by the main port to select the main member device, and only uses the main port to decide whether IRF link splitting occurs. Under the condition that the working states of all IRF ports of the member equipment are effective, if a first heartbeat message is received through a main port, processing the first heartbeat message according to the existing processing mode; if the first heartbeat message is received from the port, no processing is carried out.
Further, in this step, selecting one port that meets the first predetermined screening rule from other IRF ports of the member device specifically includes:
and selecting a port with the minimum port number from other IRF ports of the member equipment to obtain the selected port.
Of course, the present invention may also adopt other screening methods, which are not listed herein.
S404: the selected port is determined to be the proxy master port for the member device.
S405: and sending a third heartbeat message carrying the working state of the port to all the neighbor devices through the proxy main port, so that all the neighbor devices set the ports corresponding to the ports to be in an invalid state after receiving the third heartbeat message.
In the invention, after all the neighbor devices receive the third heartbeat message, the ports corresponding to the ports are set to be in an invalid state, so that the ports corresponding to the ports can only send the first heartbeat message, and the condition that the data message is lost because the port at the opposite end cannot receive the data message due to faults is avoided.
It should be noted that, for the master member device in the present invention, after receiving the third heartbeat packet, in addition to executing the above operations, the master member device may re-screen a new master port from other IRF ports according to a certain screening rule, and notify the identity information of the new master port to its own neighbor devices (all slave member devices) to change the roles of the corresponding ports, so as to better maintain the stability of the IRF system and avoid frequent IRF link splitting due to port failure.
S406: and when a fourth heartbeat message which is sent by the main member equipment and carries the identity information of the new main port is received, setting the port corresponding to the new main port as the new main port of the port.
In this step, the fourth heartbeat message is sent after the main member device selects a new main port from other IRF ports of the main member device according to a second predetermined screening rule after receiving the third heartbeat message.
The second predetermined filtering rule may be the same as or different from the first predetermined filtering rule. Accordingly, the third predetermined filtering rule mentioned later may be the same as or different from the second predetermined filtering rule and the first predetermined filtering rule.
By applying the embodiment of the invention, the member equipment in the IRF system sets the IRF port with the fault to be in an invalid state, so that the IRF port can only send the first heartbeat message and can not send the data message; further, when the member device is a slave member device and the IRF port with the fault is a master port, the proxy master port is re-screened from other IRF ports of the member device to notify the neighbor device to set the port corresponding to the IRF port with the fault to an invalid state, so that the situation that when the port at one end on the IRF link fails, and the port at the opposite end continuously sends a data message to the port with the fault due to the unknown fault, so that the data message is lost is avoided. And when receiving the heartbeat message which is sent by the main member device and carries the identity information of the new main port, the member device sets the port corresponding to the new main port as the new main port of the member device. The main port on the main member device is used for maintaining the stability of the IRF system, and the main port on the main member device in the IRF system is in an effective state, so that the situation of IRF link splitting in the IRF system is reduced.
Further, in the present invention, after determining that the port has failed, if the member device is a master member device and the port is a master port, the member device may perform the following first processing operation or may perform a second processing operation:
the first method comprises the following steps: selecting one port meeting the second preset screening rule from other IRF ports of the member equipment, and determining the selected port as a new main port of the member equipment;
and sending a fifth heartbeat message carrying the working state of the port and the identity information of the new main port to all the neighbor devices through the new main port, so that after all the neighbor devices receive the fifth heartbeat message, the port corresponding to the port is set to be in an invalid state, and the port corresponding to the new main port is set to be the main port.
And the second method comprises the following steps: selecting one port which accords with a third preset screening rule from other IRF ports of the member equipment, and determining the selected port as a standby main port of the member equipment;
sending the third heartbeat message to all the neighbor devices through the alternative main port, so that after all the neighbor devices receive the third heartbeat message, the ports corresponding to the ports are set to be in an invalid state;
selecting one port meeting the second preset screening rule from other IRF ports of the member equipment, and determining the selected port as a new main port of the member equipment;
and sending a sixth heartbeat message carrying the identity information of the new main port to all the neighbor devices through the new main port, so that all the neighbor member devices set the port corresponding to the new main port as the main port after receiving the sixth heartbeat message.
It should be noted that, in the present invention, after determining that the port fails, the member device, regardless of whether the member device is a master member device or a slave member device, may perform: and sending the third heartbeat message to all the neighbor devices through the main port of the member device, so that all the neighbor devices set the ports corresponding to the ports to be in an invalid state after receiving the third heartbeat message. Therefore, all the neighbor devices do not send data messages through the IRF link where the port is located any more, and packet loss is reduced.
Furthermore, in the present invention, when the port of the member device fails, the port needs to be recovered to ensure normal data communication.
After the recovering, it may further be performed for the member device to: after receiving the first heartbeat message through the port, the working state of the port is recovered to be an effective state, and the third heartbeat message is sent to all the neighbor devices through the current main port of the member device. After all the neighbor devices receive the third heartbeat message, the ports corresponding to the ports are recovered to be in an effective state, and therefore normal transmission of data messages is guaranteed.
The port fault handling method provided by the embodiment of the present invention is described below by using a specific embodiment. The first, second, third and fourth subsequently occurring Hello messages are all Hello messages in the IRF system.
As shown in fig. 2, after the IRF system is successfully established, assuming that the priority of the device a-IRF1 is greater than the priorities of the device B-IRF2 and the device C-IRF3, the device a-IRF1 is a master member device, and the device B-IRF2 and the device C-IRF3 are all slave member devices.
For device a-IRF1, assuming that port1/1 is selected as the master port according to the second predetermined filtering rule, port1/2 and port1/3 are set as slave ports, and a second heartbeat packet (second Hello packet) is sent to device B-IRF2 and device C-IRF3 through port1/1, and identity information that port1/1 is the master port is notified to device B-IRF2 and device C-IRF 3. Subsequently, after receiving the second Hello message, the device B-IRF2 sets the Port2/1 corresponding to the Port1/1 as a master Port, and sets the ports 2/2 and 2/3 as slave ports; after receiving the second Hello packet, the device C-IRF3 sets Port3/1 corresponding to Port1/1 as the master Port, and sets Port3/2 and Port3/3 as the slave ports.
In addition, in the initial state, port1/1, port1/2 and port1/3 of device a-IRF1, port2/1, port2/2 and port2/3 of device B-IRF2, and port3/1, port3/2 and port3/3 of device C-IRF3 are all set to be valid states (valid), that is, a first heartbeat message (first Hello message) and a data message can be sent between each other. It should be noted that each device only processes the first heartbeat packet received through the primary port.
As shown in fig. 3, assuming that a port2/1 connected to a two-layer network on the device B-IRF2 is loose, the device B-IRF2 cannot receive the first Hello message sent by the device a-IRF1 or the device C-IRF3 through the port2/1 within a predetermined time period, in this case, device B-IRF2 determines that port2/1 failed, sets port2/1 to an inactive state, since port2/1 is the master port of device B-IRF2, at this time, device B-IRF2 selects one from port2/2 and port2/3 as a proxy master port according to a first predetermined filtering rule, assuming that the port number of port2/2 is smaller than the port number of port2/3, determines port2/2 as a proxy master port, and sending a third heartbeat message (a third Hello message) carrying the working state of the port2/1 to the device A-IRF1 and the device C-IRF3 through the port 2/2. Subsequently, device a-IRF1 sets corresponding port1/1 to be in an invalid state (only sends a first heartbeat packet), selects one of port1/2 and port1/3 as a master port, and determines port1/2 as the master port of device a-IRF1, assuming that the port number of port1/2 is smaller than the port number of port1/3, device a-IRF1 sends a fourth heartbeat packet (fourth Hello packet) to device B-IRF2 and device C-IRF3, where the fourth Hello packet carries the identity information of the new master port of device a-IRF1 (at this time, port1/2), device B-IRF2 receives the fourth Hello packet, and determines corresponding port2/2 as the new master port of device B-IRF 2.
After receiving the third Hello message, the device C-IRF3 sets the corresponding port3/1 to an invalid state (only sends the first heartbeat message); after receiving the fourth Hello message, determining the corresponding port3/2 as a new master port of the device C-IRF 3.
When device B-IRF2 receives the first Hello packet sent by device a-IRF1 or device C-IRF3 again through failed port2/1, port2/1 is set to an active state, and a third heartbeat packet (third Hello packet) carrying the recovery of the working state of port2/1 is sent to device a-IRF1 and device C-IRF3 through port2/2, and after device a-IRF1 receives the third Hello packet, port1/1 is set to an active state, and at this time, port1/1 may send both the first Hello packet and the data packet to device B-IRF 2.
After receiving the third Hello packet, the device C-IRF3 sets the port3/1 to an active state, and at this time, the port3/1 may send the first Hello packet to the device B-IRF2 and the device a-IRF1, and may send a data packet.
Assuming that port2/2 or port2/3 of device B-IRF2 fails, device B-IRF2 sends a third heartbeat packet to device a-IRF1 and device C-IRF3 through port 2/1. After the subsequent device A-IRF1 receives the third heartbeat message, the port1/2 of the device A-IRF1 is set to be in an invalid state; after receiving the third heartbeat message, the device C-IRF3 sets the port3/2 of the device C-IRF3 to an invalid state.
For the processing procedure of the failure of port1/1 and the processing procedure of the failure of port1/2 or port1/3 of the device a-IRF1, see the related description in the above method, which is not illustrated here.
