Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a method and an apparatus for a physical port to join or leave an aggregation port. BACKGROUND OF THE INVENTION Support for a virtual local area network (VLAN) in a switch is an important function. When the size of the network is relatively large, the management of the VLAN is complicated. GVRP (GRP VLAN Registration Protocol) is a protocol defined to address the dynamic configuration of VLAN attributes. Configure a few switches in the network, and the VLAN information can be distributed and propagated in the network. All the switches on the network can be consistent with each other in the VLAN configuration to implement free communication. As the aggregation port and aggregation link exist on the network, GVRP protocol support for aggregation ports becomes more important. An aggregation port is an entity that is uniquely identifiable by any grouping of one or several ports for aggregation reasons. In addition, GVRP is an application protocol of the GARP protocol. It uses the GRP (GRP Information Declaration) resource in the GARP (Generic Attribute Registration Protocol). When a port is enabled with the GVRP protocol. At the same time, it will occupy a GID. Under normal circumstances, a device will open the GVRP protocol on multiple ports, so the rational use of GID resources is also a key issue. In the technical solution of adding an existing physical port to an aggregation port, the physical port does not release its GID resources after it is added to the aggregation port. Therefore, the GID resource of the device cannot be properly utilized. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a method and apparatus for a physical port to join/exit an aggregation port, so as to at least solve the problem that the GID resource of the device cannot be reasonably utilized. According to an aspect of the present invention, a method for a physical port to join an aggregation port is provided, including: executing an instruction that a physical port joins an aggregation port; determining whether a physical virtual port is enabled with a general virtual The local area network registration protocol GVRP function; if yes, the physical port releases the GID resource and joins the aggregation port. Preferably, when the GVRP function is enabled on the aggregation port, the physical port releases the GID resource and joins the aggregation port, including: the physical port is deactivated from the dynamic virtual office i or the network vlan, the GID resource is released, and the dynamic vlan of the aggregation port is added. And use the same GID resource as the aggregate port. Preferably, before determining whether the physical port is enabled with the GVRP function, the method further includes: determining whether the static vlan attribute of the physical port is consistent with the aggregation port; if yes, determining whether the physical port has the GVRP function enabled; if not, the physical port is added. The aggregation port failed, and the attributes of the physical port and the aggregation port remain unchanged. Preferably, after the physical port releases the GID resource and joins the aggregation port, the physical port also exits the aggregation port. According to another aspect of the present invention, a method for a physical port to exit an aggregation port is provided, including: executing an instruction that a physical port exits an aggregation port; and the physical port exits the aggregation port, and determines whether the GVRP function is enabled before the physical port joins the aggregation port. If yes, the physical port re-applies for the GID resource and enables the GVRP function of the physical port. Preferably, when the GVRP function is enabled on the aggregation port, the physical port exits the aggregation port, including: the physical port deregisters its dynamic VLAN, releases the GID resource, and disables the GVRP function. According to still another aspect of the present invention, an apparatus for adding a physical port to an aggregation port includes: adding an instruction execution module, configured to execute an instruction to join a physical port to an aggregation port; and determining, by the first determination module, whether the physical port is enabled GVRP function; release module, set to release the GID resource of the physical port, and add the physical port to the aggregation port. Preferably, in the case that the GVRP function is enabled on the aggregation port, the release module is also used to cancel the dynamic VLAN of the physical port, release the GID resource of the physical port, and add the physical port to the dynamic VLAN where the aggregation port is located, so that the physical port is aggregated. Preferably, the port uses the same GID resource, and further includes: a second determining mode, configured to determine whether the static vlan attribute of the physical port is consistent with the aggregation port before the first determining module determines whether the physical port has the GVRP function enabled; if not, The physical port fails to be added to the aggregation port. The attributes of the physical port and the aggregation port remain unchanged.
