Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Embodiment
The present embodiment provides a kind of interface index management method of core switch, and as shown in Figure 1, the interface index management method of described core switch comprises:
Interface index number for the unique correspondence of each port assignment on each groove position of core switch.The fixing interface index number of the corresponding binding one of described port, i.e. static interface call number; Described static interface call number can be determined according to the numbering of the numbering of groove position, described port place and described port is unique.Wherein, described port does not comprise the XE port in core switch; Described port comprises one or more in port in master control board slot position, the port in business board slot position, virtual aggregation port.Described static interface call number in the present invention can be referred to as interface index number.
For being inserted with the groove position of board on core switch, go up MAC Address of each port assignment of wire casing position.
The corresponding relation of setting up the MAC Address of each port of described upper wire casing position and interface index number, forms index relative table.
Further, the numbering of described static interface call number comprises: the groove bit number of core switch and the port numbering on groove position, jointly consist of.For example: the setting means of described groove bit number comprises: according to the order setting slot bit number of the physical location of each groove position on core switch; The setting means of described port numbering comprises: according to the order of the physical location of each port in each groove position, set port numbering; The numbering of described static interface call number is sequentially rearranged by groove bit number and port numbering.
For example, adopt the mode of structure of arrays to manage groove position, port and board.For whole core switch, groove position board structure Slot_Struct is defined as to array, array size is the maximum number of slots that core switch is supported, by Slot_No(groove bit number) point to the data that corresponding array index can obtain certain piece groove position board; The members such as port numbering, port type are preserved in board structure inside, groove position.A port counter Port_No who preserves in the board structure of groove position, this port counter can be regarded as vernier or pointer in subsequent applications, often reach the standard grade a board port (be called for short port or interface) counter add 1, the port numbering of reaching the standard grade to record current business plate.The mode of obtaining port numbering is: Slot_Struct[Slot_No] .Port_No.
The management process of interface index number is: the Base Serial Number of interface index is defined as IF_INDEX_BASE(and is defined as 1 here).Reserved Main_Board_Port_Num interface index number given master control borad, for future master control borad activate business; Suppose Main_Board_Port_Num=64, interface index number 1～64 is kept for master control borad, for the situation of master control borad supporting business port, can directly use this interface index number.The Base Serial Number of business board interface index is the interface index number of master control borad immediately, and according to above-mentioned hypothesis, the initial call number of business board is 65.Suppose that it is 8 that maximum traffic plate is counted Board_Num, the maximum port number Borad_Port_Num in single groove position is 64, line card (being business board) interface index sum All_Service_Port_Num=Board_Num * Borad_Port_Num=8 * 64=512.XE mouth need be done special processing.Due to XE mouth reach the standard grade in time or position on all without saying in proper order, therefore must take poll to detect the mode in room to the allocation space of XE mouth, be that the reserved maximum XE_Num(of each line card supposes that this value is 16) individual XE mouth, reserved area is that every groove position XE_Num port reciprocal is to last port.This XE mouth allocation space is still in this groove bit space, and XE_Num must be less than or equal to Borad_Port_Num.Single groove position interface index distributes diagram as shown in Figure 2.Aggregation port is counted reserved 128 of Agg_Port_Num hypothesis, and aggregation port divides again dynamically and static two classes, and demarcation interval manages respectively, and the first half Agg_Port_Num call number is kept for sa, and later half Agg_Port_Num call number is kept for po.
In the present invention, non-XE port adopts the mode of static binding dynamic assignment, without to system application extra resource, as long as get the parameters such as current groove bit number of reaching the standard grade, port numbering, port type, just can calculate interface index deviant, add interface index initial address and can draw interface index number.
As: the interface index computing formula of business board is:
if_index=IF_INDEX_BASE+Main_Board_Port_Num+Borad_Port_Num*(Slot_No-1)+Slot_Struct[Slot_No].Port_No。
The interface index computing formula of master control borad is:
if_index=IF_INDEX_BASE+Slot_Struct[Slot_No].Port_No。
Owing to being the relation of shining upon one by one, therefore can draw interface index number as long as calculate index offset value, do not need to search again, relatively and judge the operations such as whether index occupied, can improve greatly allocative efficiency, thus lifting means performance greatly.
Index managing method of the present invention also can be applied to the index management to MAC Address, according to this index, takes out the MAC Address of this interface from MAC Address pond again, just definable different length on the width of resource bid and allocation table, as required definition.Computing formula and interface index are basic identical, as long as replace relevant parameter.First by system, provide a MAC Address pond, this is the MAC Address that pre-first to file is good.That next will do is just basically identical with the distribution of port index management method of the present invention.When non-XE mouth rolls off the production line, for interface index and MAC Address index, except XE mouth, other port types are all without carrying out releasing operation, the unique processing that will do is, when having a port to roll off the production line, by Slot_Struct[Slot_No] .Port_No subtracts 1 operation.When having XE mouth to roll off the production line, need the management space of XE to carry out releasing operation, to abdicate space to the XE mouth of reaching the standard grade below.
