Accompanying drawing explanation
Fig. 1 is the method flow diagram of compatible SUPER VLAN Yu VLANIF in embodiment of the present invention IPRAN system.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As it is shown in figure 1, the method for compatible SUPER VLAN Yu VLANIF in IPRAN system, specifically include following steps:
S1. create a new VLAN, port list (port_list) and vlan list (vlan_list) are set simultaneously.Creating a new VLAN, need to create a VLAN ID for this new VLAN, therefore to judge whether this VLAN ID exists, if so, prompting user creates failure；If it is not, then create successfully.Concrete, IPRAN system is provided with the vlan data table storing all vlan informations, one VLAN takies a data structure object, by searching the vlan data table of current data structure, judge whether VLAN ID exists, if VLAN ID is present in vlan data table, then illustrates that this is not newly created VLAN ID, create unsuccessfully.
S2. specifying the VLAN type of establishment is SUB VLAN or COMMON is VLAN, if COMMON is VLAN, enters S3, if SUB is VLAN, enters S5.Without Selective type, then acquiescence is COMMON VLAN.
S3. will create COMMON VLAN and bind two layers of ethernet port.
S4. create the VLANIF interface of ID identical with COMMON VLAN, three layers of attribute of configuration VLANIF, complete.Three layers of attribute of concrete VLANIF include IP, MAC of VLANIF, and enable attribute such as ldp, igmp, arp etc. of three layers.
S5. the SUB VLAN created is bound two layers of ethernet port.
Create a new VLAN the most again, need also exist for judging whether this VLAN ID exists, after creating successfully, it is intended that the VLAN type again created is SUPER VLAN, meanwhile, automatically create three layer interfaces of SUPER VLAN.
S7. using the SUB VLAN of described two layers of ethernet port of binding as Sub-VLAN, it is tied in described SUPER VLAN.
S8. configure three layers of attribute of SUPER VLAN, complete.Concrete, three layers of attribute of SUPER VLAN the most also include IP, MAC of VLANIF, and enable attribute such as ldp, igmp, arp etc. of three layers.
In above-mentioned steps, different types of VLAN, order is with differently configured, and such as COMMON VLAN can not cannot function as the Sub-VLAN of SUB VLAN, it is impossible to binds therewith.After three layers of attribute configuration of SUPER VLAN complete, the amendment of VLAN type can be completed by amendment VLAN type.Such as, establishment for SUB VLAN10, bind two layers of ethernet port；SUPER VLAN100, SUB VLAN10 are as Sub-VLAN in establishment, are bundled in SUPER VLAN 100.When the type revising SUPER VLAN100 is COMMON VLAN, IPRAN system is automatically deleted the binding relationship of SUPER VLAN100 and SUB VLAN10, and deletes three layers of attribute of SUPER VLAN.
Table 1
Table 1 is the essential information of vlan data structure, contains the information such as VLAN description, VLAN ID, VLAN type, three layer interfaces.It can be seen that VLAN ID is globally unique, after creating a VLAN, it is impossible to create other VLANs identical with its ID again.
Described COMMON VLAN, SUB VLAN are identical with the data structure of SUPER VLAN, and parameter role is distinguished dissimilar, and parameter role is 0, represent COMMON VLAN；Parameter role is 1 expression SUB VLAN, and parameter role is 2 expression SUPER VLAN.Each type of VLAN purposes is different, SUPER VLAN and SUB VLAN must be with the use of, just can successfully create a SUPER VLAN, two layers of ethernet port are added in SUB VLAN, to realize the Layer2 switching of vlan domain, SUB VLAN is bound, so that the user in each SUB VLAN can access three-layer network in SUPER VLAN.COMMON VLAN after creation, needs to bind two layers of ethernet port, to realize Layer2 switching.When it does not creates VLANIF, it is a common two layer VLAN, Layer2 switching business can only be realized.After creating VLANIF, possess three layer functions, as three layer interfaces, can both support that two layer services also supported three layer services with configuration of IP address.COMMON VLAN with bundling port, and can create three layer interfaces and three layers of attribute, but can not join in SUPER VLAN.
Arranging a common pointer (ifp) in described data structure, when, under COMMON VLAN type, configuring three layers of attribute of VLANIF, or when creating SUPER VLAN, common pointer points to three layer interfaces created；When for SUB VLAN type, arranging a parameter pointer (parentvlan), parameter pointer points to its SUPER VLAN added.
When VLAN type is COMMON VLAN or during SUB VLAN, and two layers of ethernet port of its binding leave in port list (port_list).When VLAN type is SUPER VLAN, the SUB VLAN of its binding leaves in vlan list (vlan_list).
Due to all VLAN ID in COMMON VLAN, SUB VLAN and SUPER VLAN shared system, so the VLAN of this several types can be managed collectively, in IPRAN system, both VLANIF and SUPER VLAN are compatible.
The present invention is not limited to above-mentioned embodiment, for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, within these improvements and modifications are also considered as protection scope of the present invention.The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
