The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
The frame device is a network device that can flexibly replace a board, has a better expandability, and has a plurality of SLOTs inside, and can be inserted into two types of boards, namely, a switch board and an interface board, as shown in fig. 1, SLOT1, SLOT2, SLOT3, and SLOT 44 are provided, wherein the interface board is inserted into SLOT1 and SLOT4, the switch board is inserted into SLOT2 and SLOT3, the boards in the SLOTs are connected through the ports of the SLOTs and transmit data, and each port is connected with only one port of the other SLOTs. In the frame device, the status of each port is periodically scanned, for example, 4 ports of an interface board in the SLOT1, if all 4 ports of the interface board in the SLOT 1_0, Ieth1_1, Ieth1_2, and Ieth1_ 34 are scanned to be in an on state, it can be considered that 4 ports are added into a shunting port set of the interface board, any message entering the interface board from Tengige1_0 and Tengige1_1 is sent to a switch board to which the port is connected by selecting only one port from the shunting port set according to a preset algorithm, and if some of the ports is scanned to be in an off state, that is, the port is not normally connected to other boards and thus a message cannot be normally forwarded, the port is deleted from the shunting port set, so as to ensure that data of the interface board cannot erroneously flow out of the port to cause errors such as data loss, and if some port scanned to be in the on state but not in the shunting port set, it is added to the offload port set to participate in data offloading.
Taking the single board and the ports shown in fig. 1 as an example, assuming that data needs to flow in from Tengige1_0 port and flow out from Tengige4_0 port, after the data flows in from Tengige1_0 port of SLOT1, the data flows in from Ieth1_0/1/2/3 port of SLOT1 to Ieth2_0/1 port of SLOT2 and Ieth3_0/1 port of SLOT3, and then flows in from Ieth2_2/3 port of SLOT2 and Ieth3_2/3 port of SLOT3 to Ieth4_0/1/2/3 port of SLOT 4. If the switching board in the SLOT3 is out of order and needs to be replaced, after the screen board is pulled out as shown in fig. 2, the Ieth1_2 port and the Ieth1_3 port of the SLOT1 and the Ieth4_2 port and the Ieth4_3 port of the SLOT4 all become closed states, and if the scanning period of the frame device is short enough, for example 100ms, the change is found in time and the 4 ports are deleted from the respective interface board shunting port sets, so that the data is prevented from flowing into or out of the 4 ports, and the error is prevented from occurring.
After the SLOT3 is inserted into a new switch board, it needs to initialize the switch board first, in which each port of the switch board is initialized one by one, for example, the Ieth3_0 port starts initialization first, after the initialization is completed, the Ieth3_1 port starts initialization again, and so on. During initialization of the Ieth3_0 port, the Ieth1_2 port receives normal port negotiation information, which results in that the connection state of the Ieth1_2 is normal, the Ieth1_2 port becomes an open state, at this time, if the device scans that the port is in the open state and is not in the offload port set of the interface board of the SLOT1, the device will add the port into the offload port set, and through selection of a preset algorithm, data in the interface board may flow out of the interface board from the Ieth1_2 port and flow into the switch board of the SLOT3 from the Ieth3_0 port, but at this time, the Ieth3_2 port and the Ieth3_3 port of the switch board may not start initialization yet, and data cannot be forwarded, so that the forwarding of data that has entered the switch board is affected, and the forwarding of the data can not be resumed until the initialization of the switch board is completed.
In order to solve the above problem, an embodiment of the present application provides a method for setting a port state of a frame device, which is shown in fig. 3 and may include the following steps:
s101, under the condition that the insertion of an exchange board is monitored, an interface board port connected with the port of the exchange board is determined;
if it is necessary to avoid that when a newly replaced switch board is not initialized yet, traffic flows from the port of the interface board connected to the newly replaced switch board, it is necessary to avoid that the port is scanned before the initialization is completed and then is added to the tributary port set of the interface board. Therefore, after a new exchange board after replacement is inserted, it is necessary to determine the port of the interface board connected to the port of the exchange board. It can be considered that a new switch board is inserted into the SLOT3 as shown in fig. 1, and ports connected thereto can be determined to be Ieth1_2, Ieth1_3, Ieth4_2, Ieth4_ 34 ports, which belong to the SLOT1 and the SLOT4, respectively. The connection relationship of each port can be determined in various ways, for example, the connection relationship can be predetermined, recorded and updated in time by maintenance personnel, and the record can be directly called when the connection relationship needs to be determined; or when the connection relation of each port needs to be determined, the maintenance personnel can be prompted to input the current condition; the connection relationship of each port can be obtained by the device through automatic detection when needed, and the like, and in addition, other various manners are also available, which need not be limited in theory in the embodiment of the present application, and a person skilled in the art can select an appropriate manner in practical application.
S102, adding a waiting opening state identifier for any determined interface board port to indicate that the interface board port is in a non-opening state;
in the process of initializing the newly replaced switch board, the interface board port connected to the port whose initialization has been started may be changed from the closed state to the open state due to normal connection, but as described above, this will cause data forwarding to be affected, so that, for any interface board port determined in S101 and connected to the port of the newly replaced switch board, a wait-to-open state flag may be added to indicate that the interface board port is not in the open state, so that the port with this flag, when the device scans the state of the port, whether it is in the closed state or the open state, will be considered as not being in the open state currently, thereby avoiding being added to the shunting port set.
S103, checking the state of the port of the exchange board under the condition that the initialization of the exchange board is monitored to be completed;
after the initialization of the newly replaced switch board is completed, it can be considered that each port has been initialized, and in order to confirm whether data can be forwarded through the ports, it can be further checked whether the states of the ports are open.
S104, for any port of the exchange board, under the condition that the port is checked to be in the opening state, deleting the waiting opening state identification of the port of the interface board connected with the port.
For any port in the switch board that has completed initialization, if it is confirmed to be in an open state by checking, that is, data can be forwarded through the port, the waiting start state identifier of the port of the interface board connected to the port can be deleted. When the port is scanned again, the real state of the port is scanned, if the port of the interface board is in an open state, the port is added into the shunting port set of the interface board through scanning, and data flows out from the port of the interface board, thereby flowing into a newly replaced exchange board for data forwarding.
In an embodiment of the present application, after determining that a certain port of the switch board is in an open state, the status of the interface board port connected to the certain port may be checked again, and when determining that the interface board port connected to the certain port is in the open state, the waiting open state flag of the interface board port is deleted again.
After the waiting open state of the port of the interface board is identified, the port needs to wait for the periodic scanning to confirm that the port is in the open state, and then the port is added into the shunting port set of the interface board, so that in order to improve the data forwarding efficiency after the exchange board is replaced, in a specific embodiment of the application, under the condition that any port of the exchange board is checked to be in the open state, or further under the condition that the port of the interface board connected with the port is also checked to be in the open state, the waiting open state identification of the port of the interface board connected with the port can be modified into the open state identification, and the port with the open state identification is added into the shunting port set of the interface board where the port is located, so that the port can participate in data flow shunting of the interface board where the port is located in time, and the data forwarding efficiency is improved. After the port is added to the set, there may be a plurality of processing manners for the opened state identifier of the port, for example, the identifier may be deleted or hidden, or may not be processed.
