Description
Technical Field
The present invention relates to the field of computer network communication technologies, and in particular, to a method and an apparatus for configuring an ethernet link aggregation group, and a computer-readable storage medium.
Background
Ethernet Link Aggregation Group (Eth-LAG) refers to a method for binding multiple Ethernet physical ports (Trunk) into one logical port. Switches or routers in the field of data communications typically use this technique to provide link redundancy and increase network bandwidth.
The Eth-LAG is a logical port, and when a packet is forwarded from the Eth-LAG, in order to achieve load balancing at a member port of the Eth-LAG, a certain physical port in the Eth-LAG is selected for forwarding through a certain routing mechanism (e.g., a hash algorithm) according to the content of the packet (e.g., MAC, IP, etc.). When the state of a link of a member port of the Eth-LAG changes, the devices at both ends of the link need to reset the Eth-LAG, and the setting of the devices at both ends may not be completely synchronous, which may result in the loss of a packet.
In the prior art, in the process of changing an Eth-LAG member port from down to up, a link two-end device acquires a state change of the Eth-LAG member, or adopts an interrupt mode, or adopts a task polling mode. In any way, the time for the devices at two ends to acquire the port to change from down to up is inconsistent. Under the influence of the asynchronism, after the end device completes the port state update and the setting of the Eth-LAG, the message is forwarded from the newly added member port to the opposite end device, and the opposite end device may not complete the port state update and the setting of the Eth-LAG, so that the message is lost.
In the prior art, when the Eth-LAG member port is changed from up to down, the link is not available. In practical application, an interruption mode is adopted to detect the state of a link changing from up to down, but in the subsequent processing process, a series of chip table entries are set, so that the time consumption is too long, and the packet loss is too much.
In summary, when the state of the member port of the Eth-LAG changes, the prior art has the problems of excessive configuration steps for the Eth-LAG, too long processing time, and asynchronous processing of the devices at the two ends of the link, thereby causing packet loss.

The configuration method of the embodiment of the invention specifically comprises the following steps:
Step 2, setting the chip, and marking all the member ports of the Eth-LAG as the member ports of the LAG in the chip, see fig. 2.
Step 3 sets up the chip, adds all the member ports of the Eth-LAG to the LAG port bitmap, see fig. 3.
And 4, calculating a port link according to the member ports of the Eth-LAG, setting the output ports of the Eth-LAG of the chips corresponding to different hash results, and including the member ports of all the Eth-LAG in the output ports. Meanwhile, each member Port is allocated with a backup Port, the backup Port is required to be a member Port of the Eth-LAG, and assuming that the Eth-LAG comprises 4 member ports 1-4, the backup Port of Port1 is set to be Port2, the backup Port of Port2 is set to be Port3, the backup Port of Port3 is set to be Port4, and the backup Port of Port4 is set to be Port1, which is shown in FIG. 3.
Step 5, when detecting that the Port status of a member is changed from up to down, for example, the Port1 status is changed to down, the LAG Port attribute and forwarding status of Port1 are kept unchanged, but the Eth-LAG output Port link set in step 3 is modified, the link with the output Port being Port1 is modified to the backup Port2 of Port1, and the message forwarded by the Port1 of Eth-LAG selected through hash operation is forwarded from Port2, see fig. 3.
Step 6, when detecting that the state of a member Port is changed from down to up, because the Eth-LAG output Port link corresponding to the down Port has been modified to its backup Port in step 4, for example, the output Port link corresponding to Port1 is modified to backup Port 2. Therefore, the packet forwarded from Port1 is selected according to the hash operation and forwarded from backup Port2, and the forwarding state of Port1 is not changed, so that the packet received from Port1 can be forwarded normally. When the update cycle is over, the Port of the outgoing Port link of the Eth-LAG corresponding to Port1 is modified from the backup Port2 to the primary Port1, and the packet is forwarded from Port1, as shown in fig. 3. The update period must be longer than the time for the devices at both ends of the link to detect and set the port state, and can be configured by command.
The flow of Eth-LAG configuration provided by the present invention is shown in fig. 4. In summary, the technical solution provided by the present invention has the following advantages:
by setting a backup port which is also the LAG member port for each Eth-LAG member port, when the state of the Eth-LAG member port is changed, the LAG member port attribute and the forwarding state of the port are not modified, only an output port link of the Eth-LAG is modified, and switching is performed between a main port and a backup port, so that the time for setting the forwarding state and the port LAG attribute is saved, and when the port is changed from up to down, quick switching can be performed, and packet loss is reduced; when the port is changed from down to up, the output port of the link is changed from the backup port to the main port after the update period is up, thereby effectively preventing packet loss.
As shown in fig. 4, a configuration method of Eth-LAG according to the technical solution of the present invention specifically includes:
501: and setting a chip, and setting all member ports of the Eth-LAG to be in a forwarding state.
502: setting up the chip, marking all member ports of the Eth-LAG as member ports of the LAG in the chip, and assigning LAG-IDs for indexing the LAG Portbitmap table and the LAG Group table, see 301 of fig. 2.
503: the chip is set up to add all member ports of the Eth-LAG to the LAG Portbitmap of the LAG ID index, indicating that the port belongs to the LAG Group, see 302 of fig. 2.
504: setting a chip, adding all member ports of the Eth-LAG to a LAG Group table, when a message is forwarded to the LAG, performing hash operation on the chip by using the content (such as MAC or IP) of the message, and indexing a hash result to the LAG Group table to obtain an egress port, which is an egress port for forwarding the message, as shown in 303-306 of fig. 2; meanwhile, a backup port is preset for each Eth-LAG member port, and the backup port must be a member port of LAG. For example, an Eth-LAG includes 4 ports 1-4, a backup Port for Port1 is Port2, a backup Port for Port2 is Port3, a backup Port for Port3 is Port4, and a backup Port for Port4 is Port 1.
505: and acquiring the link states of each member of the Eth-LAG one by one, if the hardware supports an interruption mode, acquiring the link states of the ports by adopting the interruption mode, and completing the updating of the message forwarding links of the equipment more quickly to reduce packet loss, otherwise, acquiring the link states of the Eth-LAG members by adopting a task timing query mode.
506: and comparing the link state of the member port of the Eth-LAG acquired this time with the last state, and judging whether the link state is changed.
507: and changing the link state of the member port of the Eth-LAG from down to up, and executing 509, otherwise, executing 508.
508: detecting that the member port of the Eth-LAG is changed from up to down, keeping the forwarding state of the port in a chip unchanged, keeping the attribute of the LAG member port of the port unchanged, keeping the port still in a bitmap of the LAG port, modifying an exit port in an LAG Group as an item of the member port, and modifying the exit port as a backup port of the member port. For example, the member Port1 status is changed from up to down, and the entry with the Port1 as the egress Port in the LAG Group is modified to be the backup Port2 of Port1, as shown in fig. 3.
509: and detecting that the down of the Eth-LAG port is changed into the up, wherein the port attribute is still a member port of the LAG because the forwarding state of the port is not changed, and the port is still in the LAG port bitmap, so that the port can normally receive the message and send the message to a forwarding engine of a local chip for forwarding. At 508, the message forwarded from the link is set to be forwarded from the backup port thereof, so that the port does not send the message to the outside temporarily, after the update period is up, the chip LAG Group table is modified, the egress port of the entry corresponding to the port is modified from the backup port to the main port, see 403 in fig. 3 to 303 in fig. 2, and thus, the main port participates in the egress port link forwarding of the LAG again. The update cycle must be longer than the interval time of port state detection and update of the devices at both ends of the link, and after the update cycle arrives, the ports of the devices at both ends of the link can normally receive and send messages, and the update cycle can be configured by commands.
In the processing process when the Eth-LAG member port state changes, when the port is changed from up to down, the LAG attribute and the forwarding state of the port in the chip are kept unchanged, and only the output port of the Eth-LAG forwarding link corresponding to the port is modified into the backup port, so that the setting steps of the chip are reduced, the purpose of quickly switching the flow to the backup port is achieved, and the packet loss is reduced; when the port is changed from down to up, the port can receive the flow, the sending of the message is still forwarded from the backup port, and the flow is switched from the backup port to the main port after the update period is up, so that the loss of the message is prevented.
The embodiment of the invention provides a method for configuring an Ethernet link aggregation group, which comprises the following processing steps:
the method comprises the following steps: setting a chip, setting all members of the Eth-LAG into a forwarding state, marking the members as LAG ports, adding the LAG ports into a LAG port bitmap, calculating port links according to the member ports of the Eth-LAG, and adding all the member ports of the Eth-LAG into output ports of LAG groups of the chip corresponding to different hash results;
step two: assigning a backup port to each member port of the Eth-LAG, wherein the backup port also belongs to the Eth-LAG and is stored in software;
step three: judging whether the state of a member port of the Eth-LAG is changed or not;
step four: when detecting that the state of a member port of the Eth-LAG is changed from up to down, modifying the list item of the port in the LAG Group table with the exit port as the port into a backup port without modifying the forwarding state and the LAG attribute of the port in the chip, so that the flow forwarded from the hash to the port is forwarded from the backup port;
step five: when the condition that the state of a certain member port of the Eth-LAG is changed from down to up is detected, after the updating period is up, the table entry of which the output port is the port in the LAG Group table is changed from the backup port to the main port.
In the embodiment of the invention, the attribute of all member ports of the Eth-LAG in a chip is the LAG port, and is always set to be in a forwarding state.
And the CPU calculates a port forwarding link according to the member port of the Eth-LAG, and sets the port into an LAG Group table of a hash result index according to different hash results corresponding to different Eth-LAG member ports.
And setting a backup port for each member port of the Eth-LAG, wherein the backup port also belongs to the Eth-LAG and is stored in software.
Judging the state change of the member port of the Eth-LAG: the state change of the port can be acquired by adopting an interrupt mode or a task polling mode.
When the port state is changed from up to down, the list item of the LAG Group table with the port as the port is modified into a backup port, and the message from the hash to the port is forwarded from the backup port.
When the port state is changed from down to up, the port can receive the message, when the set update period is reached, the output port of the LAG Group table corresponding to the port is changed from the backup port to the local port, and the update period needs to be longer than the time for detecting and updating the port state at two ends of the link.
In the embodiment of the invention, the key point is how to quickly switch the message forwarded from the port to other links when detecting that the port is changed from up to down:
keeping the port in a forwarding state in the chip;
not modifying LAG attributes of ports in a chip and still belonging to port bitmaps of LAGs;
only the output port of the LAG Group table corresponding to the port is set as a backup port, when the message is transmitted to the LAG and the LAG Group table is selected through a hash algorithm, the message is transmitted from the backup port, the backup port is an up port, if the backup port is down, the backup port of the backup port is selected, and the like.
In the embodiment of the invention, the key of the configuration method for realizing the Ethernet link aggregation group is how to ensure that the message forwarded from the port is not lost when the port is detected to be changed from down to up:
because the port can not transmit state in the chip all the time, the message can be received normally;
because the port attribute is the LAG attribute and is in the LAG port bitmap, the received message can not be forwarded in the Eth-LAG and can be normally forwarded to other ports;
before the update period is not reached, forwarding the message from the hash to the port from the backup port;
and after the update period is up, the link at the opposite end can already receive the message, the output port of the LAG Group table corresponding to the port is changed from the backup port to the main port, the port participates in the actual message transmission, and the update period is configurable.
In the embodiment of the invention, the method for realizing the fast link switching from up to down of the ports of the aggregation group members can quickly replace the output port of the forwarding link corresponding to the down member port with the backup port, realize the fast switching of the flow and reduce the packet loss.
In the embodiment of the invention, the link switching method from down to up of the member port of the aggregation group is realized, after the update period is up, the output port of the forwarding link corresponding to the up member port is changed from the backup port to the main port, and the loss of the message is effectively prevented.
In the embodiment of the invention, when the member port of the Eth-LAG is changed from down to up, no packet is lost, and when the member port of the Eth-LAG is changed from up to down, the packet loss is reduced.
In the embodiment of the invention, Eth-LAG: ethernet Link Aggregation Group, Ethernet Link Aggregation Group.
