Embodiment 1

[0035] The embodiment of the present invention proposes a method for creating a VLAN sub-interface, see figure 2 , the method includes:

[0036] Step 201: assigning a VLAN sub-interface to each of the extended interfaces under the uplink port;

[0037] Step 202: Use the remaining undivided VLAN sub-interfaces to create an extended sub-interface under the extended interface.

[0038] Wherein, step 202 includes: creating an extended sub-interface under the extended interface and registering it in the kernel, and each of the extended sub-interfaces occupies an undivided VLAN sub-interface.

[0039] Moreover, the extended sub-interface is an extended sub-interface of the extended interface in terms of interface relationship, and occupies the bandwidth of the extended interface in actual use; the extended sub-interface is an extended sub-interface of the uplink port in terms of logical relationship , occupies a VLAN sub-interface during the packet forwarding process.

Embodiment 2

[0050] The embodiment of the present invention proposes a switch chip using a method for creating VLAN sub-interfaces, the relationship between appearance and physical connection is the same as figure 1 The switch chip in is the same, the chip includes:

[0051] One uplink port, which is the main interface of several VLAN sub-interfaces;

[0052] Several extended interfaces, each of which occupies a VLAN sub-interface, and several extended sub-interfaces are created under each of the extended interfaces.

[0053] Wherein, each extended sub-interface occupies a VLAN sub-interface not occupied by the extended interface, and this relationship is registered in the kernel. The extended sub-interface is an extended sub-interface of the extended interface in terms of interface relationship, and occupies the bandwidth of the extended interface in actual use. The extended sub-interface is logically an extended sub-interface of the uplink port, and occupies a VLAN sub-interface in the...

Abstract

The invention, which relates to the technical field of communication, brings forward a method for establishing a virtual local area network (VLAN) subinterface and an exchange chip using the same. The method comprises the following steps: dividing a VLAN subinterface for each expansion interface at an uplink port; and using the rest of undivided VLAN subinterfaces to establish expansion subinterfaces at the expansion interfaces. According to the invention, on the premise that the original interface relation is not changed, the exchange chip can provide support for more VLAN interfaces.

Description

technical field [0001] The invention relates to communication technology, in particular to a method for creating VLAN (Virtual Local Area Network, virtual local area network) sub-interfaces and a switching chip using the method. Background technique [0002] At present, using the VLAN isolation feature of the switch chip to multiplex the interface of the network forwarding chip CPU has become a common interface expansion method for network equipment manufacturers. This method is cost-effective, can effectively increase the number of interfaces, and improve the competitiveness of products, which is a trend in future equipment development. [0003] The hardware architecture of a basic network device with a switch chip is as follows: the interface of the forwarding chip CPU is connected to the switch chip, and more interfaces are divided by the switch chip for use. In order to prevent the packets sent by each interface from interfering with each other, the switch chip seals di...
