The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The existing port convergence method is based on that the switching chip has a port convergence function, and registers related to port convergence are directly configured, the method needs to be matched with the switching chip to support the port convergence function, and if the switching chip does not support the port convergence function, the port convergence function cannot be realized.
Therefore, the embodiment of the present invention provides a port convergence method based on port isolation, and the method only needs the switch chip to support the port isolation function, and only realizes the port convergence function in a port isolation manner. The method solves the problem that the existing port convergence method depends on the switching chip in the switch to support the port convergence function, and if the switching chip does not support, the port convergence can not be realized. The following description and description will proceed with reference being made to various embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart of a port aggregation method based on port isolation according to an embodiment of the present invention, where the method includes:
s1, forming a plurality of ports in the switch into a convergence port, wherein any two ports in the convergence port are isolated from each other.
S2, forming a port group by the other ports in the switch and any one of the aggregation ports, and isolating the other ports except the any one of the aggregation ports from each other.
Here, the ports other than the aggregation port include a switch normal port and a CPU port. Each port of the switch has a port isolation bit table, e.g. a 9-bit bitmap (8 ports plus one CPU port) for an 8-port switch chip, the default values of which are shown in table 1:
TABLE 1
The bit value of each port corresponding to itself is 0, which indicates that data entering from the port will not exit from the port, for example, the first bit of the bitmap corresponding to port1 is 0. In actual use, if port1 and 2 isolation is required, i.e. data of port1 and port2 do not intercommunicate, the corresponding bit is set to 0, e.g. port1 and port2 are isolated, the second bit of port1 is set to 0, and the first bit of corresponding port2 is set to 0.
In this embodiment, port1 and port2 of switch 1 constitute a port aggregation port. The data of port1 and port2 are not sent to each other, and the corresponding bit of the port bit table is set to 0, as detailed in table 2.
TABLE 2

| port 1 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 | 1 |
| port 2 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 | 1 |
| port 3 | 1 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 |

| port 7 | 1 | 0 | 1 | 1 | 1 | 1 | 0 | 1 | 1 |
| port 8 | 0 | 1 | 1 | 1 | 1 | 1 | 1 | 0 | 1 |

Port3 and port1 are isolated from each other or port3 and port2 are isolated from each other, and port4 and port1 are isolated from each other or port3 and port2 are isolated from each other
The configuration of Port5 to Port8 is similar to the Port3 and Port4 configurations. The purpose of this configuration is to prevent incoming broadcast packets from port3 or port4 from having two broadcast packets sent from the port sink.
By the method, under the condition that the exchange chip does not support port convergence but supports the port isolation function, the port convergence function is realized only by port isolation in the exchanger.
On the basis of the above embodiments, in order to implement load balancing of the aggregation ports, when other ports in the switch and the aggregation ports form a port group, balanced configuration is required.
For example, for an 8-port switch chip (without CPU port), if port1 and port2 are a convergence port, port3 selects port1 and other ports to form a port group, port4 selects port2 and other ports to form a port group, port5 selects port1 and other ports to form a port group, port6 selects port2 and other ports to form a port group, port7 selects port1 and other ports to form a port group, port8 selects port2 and other ports to form a port group, and CPU port selects port1 and other ports to form a port group.
On the basis of the above embodiment, the method further includes forming a port group by the CPU port in the switch, any one of the aggregation ports, and the other ports in the switch.
Specifically, during the port configuration process, as shown in table 2, the CPU interface forms a port group with port1 of the aggregation port, and simultaneously forms a port group with all ports of port3-port 8.
On the basis of the above embodiment, a plurality of ports in the switch are combined into a convergence port, wherein the step of isolating any two ports in the convergence port from each other specifically includes: the method comprises the steps that a first port, a second port and a third port in a switch form a convergence port, wherein the first port, the second port and the third port are isolated from each other.
The step of forming a port group by other ports in the switch and any port in the aggregation port, and isolating the other ports except the any port in the aggregation port from each other at the same time specifically includes: and respectively forming other ports of the switch and any port in the convergence ports into a port group, and simultaneously isolating the other ports except any port in the convergence ports from each other.
In this embodiment, several ports of a switch are combined into one aggregation port, for example, port1, port2 and port3 of the switch are combined into an aggregation port, where port1, port2 and port3 are isolated from each other, that is, data of port1, port2 and port3 are not sent to each other, and common ports, that is, port4-port8, can only be in one group with one of the aggregation ports and isolated from other ports in the aggregation port, for example, port4 and port1 are in one group, and are isolated from port2 and port 3; the port5 ports are in a group with the port2 ports, and are isolated from the port1 and the port3 ports; port6 is in a group with port3 ports, isolated from port1 and port2 ports; port7 is in a group with port1 ports, isolated from port2 and port3 ports; port8 ports are grouped with port2 ports, isolated from port1 and port3 ports. The specific port phases are shown in table 3.
TABLE 3
| bit | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | cpu |
| port 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 |
| port 2 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 |
| port 3 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 |
| port 4 | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | 1 |
| port 5 | 0 | 1 | 0 | 1 | 0 | 1 | 1 | 1 | 1 |
| port 6 | 0 | 0 | 1 | 1 | 1 | 0 | 1 | 1 | 1 |
| port 7 | 1 | 0 | 0 | 1 | 1 | 1 | 0 | 1 | 1 |
| port 8 | 0 | 1 | 0 | 1 | 1 | 1 | 1 | 0 | 1 |
| cpu | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 | 0 |
On the basis of the above embodiment, the method further includes: acquiring state information of each port in the convergence ports; and if any port in the convergence ports is in a disconnection state, reconfiguring the ports of the switch.
Specifically, in order to prevent the port that the ports converge from being disconnected, the states of port1, port2, and port3 are monitored in real time during the actual operation process, and when one of 1 port that the ports converge is disconnected, the port isolation is reconfigured.
In summary, the port convergence method based on port isolation provided in the embodiments of the present invention overcomes the problem that the conventional port convergence scheme is limited by the switch chip, and implements the port convergence function through the port isolation method.

Specifically, port1 and port2 of switch 1 constitute a port aggregation port. The data of port1 and port2 are not sent to each other, and the corresponding bit of the port bit table is set to 0, as detailed in table 2.
Port3 and port1 are isolated from each other or port3 and port2 are isolated from each other, port4 and port1 are isolated from each other or port3 and port2 are isolated from each other
The configuration of Port5 to Port8 is similar to the Port3 and Port4 configurations. The purpose of this configuration is to prevent incoming broadcast packets from port3 or port4 from having two broadcast packets sent from the port sink.
By the system, under the condition that the exchange chip does not need to support port convergence and only needs to support the port isolation function, the port convergence function is realized only by port isolation in the switch.
