Problems solved by technology

When the monitoring equipment only has Ethernet ports, and the in-band Ethernet ports provided by the switch chip are insufficient, at present, it is necessary to replace the switch to provide more in-band Ethernet ports. In this way, not only the current network operation must be interrupted , also increases the cost

Embodiment Construction

[0021] The Ethernet port of the CPU of the switch is used as the CPU debugging port, inter-board communication port, or local network element management port. The uplink port is the in-band Ethernet port provided by the switch chip of the switch. The invention realizes data transmission between the Ethernet port of the CPU and the uplink port by configuring a transparent channel virtual subnet (VLAN) and constructing a transparent channel between the CPU's Ethernet port and the uplink port.

[0022] The method for realizing the transparent transmission of network data in the present invention comprises the following steps:

[0023] Step A: Configure a transparent channel VLAN on the CPU, add the uplink port to the transparent channel VLAN, and record the label of the uplink port as the tag (TAG) of the transparent channel VLAN, so that the uplink port can receive For data packets labeled as TAG, the transparent channel VLAN is actually located between the CPU and the switch c...

Abstract

The invention discloses a method to realize the network data transparent transmission. The method can realize the data transmission between an Ethernet port and an uplink-port of the CPU by the configuration of a transparent tunnel virtual subnet VLAN. The invention also discloses a device to realize the network data transparent transmission, the device includes an exchanger, a transparent tunnel module is arranged on the exchanger, the transparent tunnel module is used to control the transmission of the up-link data packets which are sent to the Ethernet port of the CPU, the up-link data packets which are sent to the Ethernet port of the CPU pass through the transparent tunnel VLAN and are sent out from the uplink-port, so as to determine the control the down-link data packets which are sent out from the Ethernet port of the CPU, further to send out the down-link data packets which shall be sent out from the Ethernet port of the CPU from the Ethernet port of the CPU. The usage of the method and the device of the invention can realize the data transmission between the Ethernet port and the uplink-port of the CPU.

Description

technical field [0001] The invention relates to the two-layer forwarding technology of the Ethernet, in particular to a method and a device for realizing transparent transmission of network data. Background technique [0002] With the increasingly widespread network applications, more and more application environments need to add monitoring equipment to the network to detect power supply, environment, etc. The monitoring information of power supply and environment obtained by the monitoring equipment needs to be sent to the monitoring center at the other end of the LAN through the switch and the LAN. The monitoring center also needs to control the monitoring equipment to a certain extent, so the monitoring equipment needs to be connected to the switch. When the monitoring equipment only has Ethernet ports, and the in-band Ethernet ports provided by the switch chip are insufficient, at present, it is necessary to replace the switch to provide more in-band Ethernet ports. In t...
