Detailed Description
To solve the problem of multiple packets in the prior art, an embodiment of the present invention provides a self-adaptive adjustment method based on a change of a switch board, which is applied to at least two service boards included in a frame network device, where the at least two service boards are connected to at least two switch boards included in the frame network device, respectively, and a flow of the method is shown in fig. 1, and the method includes the following steps:
s11: after the switching board card change event is monitored, the inline ports with unchanged connection states are obtained to obtain a first inline port set, and the inline ports connected with the changed switching board card are obtained to obtain a second inline port set.
And the service board card is connected with at least two exchange board cards, and if the exchange board card is pulled out or the exchange board card is reset, the exchange board card change event is monitored. At this time, the inline ports whose connection state is not changed may be acquired, and these ports may be defined as a first inline port set, and the inline ports connected to the changed board card may be acquired, and these ports may be defined as a second inline port set.
S12: and setting each port included in the second inline port set in the non-unicast blocking table as a port in the first inline port set which is prohibited from forwarding and put through by each table entry in the non-unicast blocking table.
The index of the non-unicast blocking table (non-unicast _ TRUNK _ BLOCK _ MASK) is a load balancing value, and the field comprises a set of blocked ports and is used for enabling non-unicast messages (including broadcast messages, multicast messages and unknown unicast messages) to be forwarded to some ports according to the load balancing value and not to be forwarded to the blocked ports.
After monitoring a switch board card change event, setting each port included in a second inline port set in a non-unicast blocking table as prohibited to be forwarded, thereby ensuring that a message does not notify each port included in the second inline port set to be forwarded, and setting each entry in the non-unicast blocking table to be put through one port in a first inline port set, each entry including one port in the first inline port set.
S13: and creating a new aggregation group corresponding to each old aggregation group where each port in the second inline port set is located, and setting the ignored fields of each table entry in the non-unicast service table to point to each new aggregation group.
Each created new aggregation group is in one-to-one correspondence with each old aggregation group, and at this time, each new aggregation group is still empty, and no port is added.
The non-unicast service table is a general term for a series of forwarding service related entries of non-unicast messages, and includes a Virtual Local Area Network (VLAN) table, an L2MC table, an L3_ IPMC table, and an IFP _ REDIRECTION _ PROFILE table, where an index is a key field of a message, a field includes a set of forwardable ports, an ignore field, and the like, and functions to provide a forwardable port of a non-unicast message and an aggregation group to be ignored, and the like.
After creating a new aggregation group corresponding to each old aggregation group where each port in the second inline port set is located, it may be set that the ignore field of each entry in the non-unicast service table points to each new aggregation group.
S14: and adding other ports except the ports contained in the second inline port set in each old aggregation group into the corresponding new aggregation group, changing the outlet of the unicast forwarding table from each old aggregation group to the corresponding new aggregation group, and changing the ignored fields of the entries in the non-unicast service table from pointing to each new aggregation group to pointing to each old aggregation group.
The unicast forwarding table is a general term for list items related to forwarding services of a series of unicast messages, and comprises an MAC address table and a three-layer forwarding table, wherein indexes are key fields of the messages, the fields comprise destination port numbers and destination chip numbers, and the unicast forwarding table is used for providing destination ports of the unicast messages.
After adding other ports in each old aggregation group except the ports contained in the second inline port set into the corresponding new aggregation group, the exit of the unicast forwarding table can be changed from each old aggregation group to the corresponding new aggregation group, so that the ports of the new aggregation group can be enabled to carry out message forwarding, the ignore field of each entry in the non-unicast service table can be changed from pointing to each new aggregation group to pointing to each old aggregation group, the new aggregation group is enabled, the old aggregation group is ignored by the ignore field, and the message forwarding by the new aggregation group is ensured.
In the scheme, the new aggregation group or the old aggregation group only takes effect at a certain moment is ensured by setting the port state in the non-unicast blocking table, adjusting the neglected fields of all the table entries in the non-unicast service table to point to all the new aggregation groups or all the old aggregation groups and changing the unicast forwarding outlet, and the new aggregation group and the old aggregation group do not take effect at the same time, so that the forwarding is carried out based on one aggregation group after the message is received, and the problem of multiple packets is avoided.
Optionally, after S14, the method further includes:
deleting the ports included in each old aggregation group, and canceling the ignore field of each entry in the non-unicast service table to point to each old aggregation group.
Because the old aggregation group does not exist, after the adjustment is made, the new aggregation group can be started, so that the ports included in each old aggregation group can be completely deleted, and the ignored fields of each entry in the non-unicast service table are cancelled to point to each old aggregation group.
Optionally, after creating a new aggregation group corresponding to each old aggregation group where each port in the second inline port set is located in S13, the method further includes:
and adding the first identification of each old aggregation group and the second identification of the corresponding new aggregation group in the omission table.
At this time, each entry in the ignore table may be configured to store an identifier of a pair of a new aggregation group and an old aggregation group, where the identifier of the old aggregation group may be defined as the first identifier, and the identifier of the new aggregation group may be defined as the second identifier. One way to create a new aggregation group is just listed here, and many other ways to create the new aggregation group are also listed here, which are not described one by one here.
Specifically, the ignoring field of each entry in the non-unicast service table set in S13 points to each new aggregation group, and the implementation process specifically includes:
acquiring the ignored fields of each table entry in the non-unicast service table;
and modifying the field value of the neglected field of each table entry into a second identifier of each new aggregation in the neglected table.
Because the ignore list records the identifications of the new aggregation group and the old aggregation group, when the ignore field of each entry in the non-unicast service list points to each new aggregation group, the field value of the ignore field of each entry can be directly modified to realize the operation.
Specifically, in the above S14, changing the ignored field of each entry in the non-unicast service table from pointing to each new aggregation group to pointing to each old aggregation group includes:
acquiring the ignored fields of each table entry in the non-unicast service table;
and modifying the field value of the ignored field of each table entry into the first identifier of each old aggregation in the ignored table.
Because the ignore table records the identifications of the new aggregation group and the old aggregation group, when the ignore field of each entry in the non-unicast service table is changed from pointing to each new aggregation group to pointing to each old aggregation group, the ignore field can be directly modified to realize the change.
Specifically, the foregoing ignoring field of canceling each entry in the non-unicast service table in S15 points to each old aggregation group, and the implementation process specifically includes:
acquiring the ignored fields of each table entry in the non-unicast service table;
and clearing the field value of the ignored field of each table entry.
Because the ignore table records the identifications of the new aggregation group and the old aggregation group, when the ignore field of each entry in the cancel non-unicast service table points to each old aggregation group, the field value of the ignore field of each entry can be directly cleared to realize the operation.
