Description
Technical field
The present invention relates to the communications field, add or exit method and the device of aggregation port in particular to a kind of physical port.
Background technology
In switch, the support of VLAN (Virtual Local Area Network, VLAN) is a very important function, when the scale of network is larger, complicated to the Comparison of Management of VLAN.The agreement that GVRP (GARP VLAN RegistrationProtocol, GARP VLAN log-in protocol) is exactly dynamic-configuration for solving VLAN attribute and defines.Be configured the minority switch in network, its vlan information can distribute propagation in a network, makes all switches on network in VLAN configuration mutually unanimously, can realize free communication.
Owing to can there is aggregation port, aggregated links in network, therefore GVRP agreement just becomes important to the support of aggregation port.Aggregation port be exactly one by because of polymerization reason, any grouping composition of one or several port can the entity of unique identification.In addition, GVRP is an application protocol of GARP agreement, it can use GARP (GenericAttribute RegistrationProtocol, Generic Attribute Registration Protocol) GID (GARP Information Declaration in agreement, GARP information declaration) resource, when a port open GVRP agreement time, a GID can be taken, generally, equipment can in multiple port open GVRP agreement, so be also a very crucial problem to the Appropriate application of GID resource.
And add in the technical scheme of aggregation port at existing physical port, usually, physical port does not discharge its GID resource, and therefore, the GID resource of equipment can not obtain Appropriate application.
Summary of the invention
Main purpose of the present invention is to provide a kind of physical port to add/exit the method and apparatus of aggregation port, can not obtain the problem of Appropriate application with the GID resource at least solving the said equipment.
According to an aspect of the present invention, provide a kind of method that physical port adds aggregation port, comprising: perform the instruction that physical port adds aggregation port; Judge whether physical port opens general virtual local network log-on protocol GVRP function; If so, then physical port release GID resource, adds aggregation port.
Further, when aggregation port opens GVRP function, physical port release GID resource, add aggregation port, comprise: physical port nullifies its dynamic virtual local area network (LAN) vlan, release GID resource, adds the dynamic vlan at aggregation port place, and uses same GID resource with aggregation port.
Further, before judging whether physical port opens GVRP function, also comprise: judge that whether the static vlan attribute of physical port is consistent with aggregation port; If so, then judge whether physical port opens GVRP function further; If not, then physical port adds aggregation port failure, and the attribute of physical port and aggregation port all remains unchanged.
Further, physical port release GID resource, after adding aggregation port, also comprises: physical port exits aggregation port.
According to a further aspect in the invention, provide a kind of method that physical port exits aggregation port, comprising: perform the instruction that physical port exits aggregation port; Physical port exits aggregation port, and judges whether physical port opens GVRP function before adding aggregation port; If so, then physical port applies for GID resource again, and opens the GVRP function of physical port.
Further, when aggregation port opens GVRP function, physical port exits aggregation port, comprising: physical port nullifies its dynamic vlan, release GID resource, and closes GVRP function.
According to a further aspect of the invention, providing the device that a kind of physical port adds aggregation port, comprising: add instruct execution module, adding the instruction of aggregation port for performing physical port; First judge module, for judging whether physical port opens GVRP function; Release module, for the GID resource of release physical port, and adds aggregation port by physical port.
Further, when aggregation port opens GVRP function, release module also for nullifying the dynamic vlan of physical port, the GID resource of release physical port, and physical port is added the dynamic vlan at aggregation port place, make physical port and aggregation port use same GID resource
Further, also comprise: second judges mould, before judging whether physical port opens GVRP function at the first judge module, judge that whether the static vlan attribute of physical port is consistent with aggregation port; If not, then physical port adds aggregation port failure, and the attribute of physical port and aggregation port all remains unchanged.
According to a further aspect of the invention, providing the device that a kind of physical port exits aggregation port, comprising: exit instruction Executive Module, exiting the instruction of aggregation port for performing physical port; Exit module, exit aggregation port for physical port, and judge whether physical port opens GVRP function before adding aggregation port; Application module, for again applying for the GID resource of physical port, and opens the GVRP function of physical port.
By the present invention, physical port, when adding aggregation port, discharges the GID resource of self, solves the problem of the GID resource rational utilization in GVRP agreement, and then reaches the effect of saving CPU and memory space.
