Embodiment
Below in conjunction with embodiment and accompanying drawing, describe technical scheme of the present invention in detail.
The message repeating control method of the Ethernet link clustering that is the embodiment of the present invention referring to Fig. 2, comprises the steps:
Step 201: create an aggregation group, at least one port is joined in described aggregation group, and the state that described aggregation group member port is set is selected state not, all aggregation group member ports are joined to aggregation group table.The spanning-tree state of member port is set in this step and the spanning-tree state of aggregation group is consistent.Described aggregation group table is for arranging the member port that aggregation group comprises.
Step 202: successively the port in aggregation group table is carried out to following operation: the operation key key that first port is set, and in the time that the Link State that judges this port is normal connection status, select aggregation group reference port according to imposing a condition, the state that reference port is set is selected state; Further judge that in described aggregation group, whether the information aggregate of other member port and the information aggregate of reference port be consistent, in this way, the state that this member port is set is selected state, otherwise the state that this member port is set is selected state not.Until all of the port in aggregation group table is executed after the operation of this step, enter step 203.
In this step, the described Operational key that port is set, the speed that comprises port reality, single dual-mode and affiliated aggregation group identifier.Wherein said port Link State, whether normal and physical link polymerize control protocol with elegance data cell (LACPDU, Link Aggregation Control Protocol Data Unit) and opposite end whether normal alternately of the real physical links state that comprises port.For manual aggregation scheme, port link is not mutual by interactive link polymerize control protocol with elegance data cell and opposite end, therefore the Link State of port is real physical links state, for dynamic aggregation pattern, port link need to be mutual by Link Aggregation Control Protocol Data Unit and opposite end, and therefore the Link State of port is determined jointly by real physical links state and the mutual situation of physical link polymerize control protocol with elegance data cell.For converging by hand pattern, the physical link state of port is as described in Table 1; Described from table 1, for manual aggregation scheme, as long as the real physical links state of port is connected state, the Link State of port is normal connection status.
The port Link State of the manual aggregation scheme of table 1
| Port real physical links state | The Link State of port |
| Connected state | Normal connection status |
| Non-connected state | Off-state |
For dynamic aggregation pattern, the real physical links state of port is as described in Table 2.As shown in Table 2, for dynamic aggregation pattern, the real physical links state of a ports having is connected state, and port link physical link polymerize control protocol with elegance data cell is normal alternately, and the Link State of port is just normal connection status.
The port Link State of table 2 dynamic aggregation pattern
In the time that the Link State that judges this port is normal connection status, select aggregation group reference port according to imposing a condition.The link priority that the described condition that becomes aggregation group reference port is port, described link priority comprises system identifier and port identifiers.Concrete system identifier comprises system priority and system mac address, and port identifiers comprises port priority and port numbers.
For manual aggregation scheme, the selection of reference port determines by the port identifiers in link priority, and the member port that aggregation group middle port priority is high is elected as the reference port of aggregation group.If the port priority of each member port is identical in aggregation group, the member port that port numbers is little is elected as the reference port of aggregation group.Certainly those skilled in the art are easy to expect, member port large port numbers can be elected as to the reference port of aggregation group completely, and this place refers to the restriction that can not serve as the application's protection range.
For dynamic aggregation pattern, the selection of reference port need to be determined jointly by the system identifier in link priority and port identifiers.Aggregation group reference port right to choose is determined by the high equipment of system identifier, compare by the system identifier of local device and the system identifier of opposite equip., in the time that the system identifier of local device is high, the selection of local aggregation group reference port is determined by the port identifiers in the link priority of member port; In the time that the system identifier of local device is low, the port identifiers of the opposite equip. that local aggregation group reference port connects according to local aggregation group member port is selected.
Determining after reference port, carry out and select logic, the information aggregate of aggregation group member port need to the information aggregate comparison of aggregation group reference port, if information aggregate is identical, port status is set to selected state, if information aggregate is not identical, port status is set to non-selected state.The information aggregate of described aggregation group member port comprises: the Operational key of port, the system priority of port place equipment, system mac address, the Operational key of the opposite equip. port being connected with this port, the system priority of Peer-Port place equipment, system mac address.
Judge that variation has occurred which port status, port status becomes selected state from selected state not; This member port is joined to polymerization mapping table.Described polymerization mapping table is the port of choosing for aggregation group port status is set, and carries out polymerization mapping.Judge the spanning-tree state of port, the spanning-tree state of described port determines by the spanning-tree state of aggregation group, if the spanning tree of aggregation group can not forwarding state, aggregation group mapping table does not carry out polymerization mapping; If the spanning-tree state forwarding state of described aggregation group, polymerization mapping table carries out polymerization mapping.Polymerization mapping table is carried out polymerization mapping, and HASH algorithm is assigned to the network service traffic equilibrium of aggregation group on its member port comprising.Be can forwarding state time at the spanning-tree state of aggregation group, E-Packet according to described aggregation group table and polymerization mapping table.
Be the message forwarding method flow chart of the Ethernet link clustering of another embodiment of the present invention referring to Fig. 3, comprise step:
The Link State of described port changes, its reason may be that the physical link of port becomes off-state from connected state, or Link Aggregation Control Protocol Data Unit is from normally becoming alternately mutual disconnection, and above-mentioned steps 204 has described in detail, repeats no more herein.
