Embodiment 1

[0068] Such as figure 2 As shown, Embodiment 1 of the present invention provides a VLAN synchronization method in a two-layer network, and the method may include:

[0069] 101. The local switch marks the VLAN synchronization information and encapsulates it into an Ethernet packet of a private Ethernet type;

[0070] Step 101 may specifically be: the local switch adds the VLAN information to be sent to the packet sending port in the form of Tag;

[0071] The VLAN information that needs to be sent is encapsulated in Ethernet in a private format.

[0072] Table 1 shows the frame structure of the Ethernet packet encapsulated by the local switch:

Embodiment 2

[0083] Such as image 3 As shown, the present embodiment takes the receiving end of the Ethernet message as the main body, and provides a VLAN synchronization method in a two-layer network, which method includes:

[0084] 201. The remote switch receives an Ethernet packet sent through a layer-2 network; the Ethernet packet is an Ethernet packet encapsulated in a private format, which includes tagged VLAN synchronization information;

[0085] The Ethernet message described in step 201 is the Ethernet message described in steps 101-102 of the first embodiment, and its encapsulation format and frame structure that can be adopted are the same as those of 101-102 of the first embodiment, and will not be repeated here. .

[0086] 202. Perform decapsulation processing on the Ethernet packet;

[0087] 203. Determine whether configuration with the local switch can be performed according to a predetermined rule;

[0088] The predetermined rule may specifically be: when the local swit...

Embodiment 3

[0108] Such as Figure 5 As shown, Embodiment 3 of the present invention provides a local switch, including:

[0109] A marking module 301, configured to mark VLAN synchronization information and encapsulate it into an Ethernet message of a private Ethernet type;

[0110] The sending module 302 is configured to send the Ethernet packet encapsulated into a private Ethernet type to the remote switch through the layer 2 network, so that the remote switch can configure with the local switch according to the Ethernet packet.

[0111]Further, the sending port of the local switch is added with the same domain name ID as the receiving port of the remote switch, wherein the local switch is configured as Server mode, and the remote switch is configured as Client mode, so that the switches at both ends can identify and forward Private Ethernet.

[0112] In a specific implementation, the marking module 301 in this embodiment is specifically used to add the VLAN information to be sent to...

Abstract

The invention discloses a VLAN synchronization method in a two-layer network, and a local switch and a remote switch based on the method. The method comprises the steps that the local switch marks VLAN synchronization information and packages into an Ethernet message of the private Ethernet type; and the packaged Ethernet message of the private Ethernet type is sent to the remote switch by the two-layer network, and thereby the remote switch and the local switch are configured according to the Ethernet message. The method solve the problem that the prior art is low in efficiency, high in labor cost and large in error probability due to that device installation staffs need to perform configuration at the site where the remote device is located.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a VLAN synchronization method in a two-layer network, and a local switch and a remote switch based on the method. Background technique [0002] In network construction and planning, a large number of zero-configuration devices are usually introduced for initial deployment or capacity expansion. For example, for a local device, it is necessary to introduce multiple remote devices to communicate with it during the expansion process, and it is necessary to perform network management on these remote devices so that they can learn synchronously with the local device. At present, in the work of introducing remote devices, equipment installers need to go to the site where the remote devices are located to configure them one by one, which not only affects the efficiency of network deployment, but also greatly increases labor costs. Manual configuration increases the chance of erro...
