Embodiment Construction

[0066] The message processing method, device and switch provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0067] An embodiment of the present invention provides a message processing method, such as figure 2 shown, including:

[0068] Step 101, the switching chip of the layer-3 authentication switch receives the data packet from the user forwarded by the layer-3 core device through the first port, and obtains the source network protocol IP address from the data packet.

[0069] Specifically, the data message from the user carries a source IP (Internet Protocol, Internet Protocol) address, and the switch chip obtains the source IP address carried in the message by parsing the message.

[0070] Step 102, assigning a preset virtual routing and forwarding identifier VRFID to the data packet.

[0071] Specifically, a preset VRFID is assigned to the data packet received through the first port, an...

Abstract

The present invention provides a message processing method, device and switch. The method includes: the switch chip of the three-layer authentication switch receives the data message from the user forwarded by the three-layer core equipment through the first port, and receives the data message from the data message Obtain the IP address of the source network protocol; assign a preset virtual routing forwarding identifier VRFID for the data message; perform a routing table query according to the source IP address and the preset VRFID, and determine whether the user is an authenticated user; If yes, send the data message to the egress device, wherein, after routing table lookup, the destination MAC address and source MAC address of the data message remain unchanged; if not, send the data message to the central processing unit CPU of the layer-3 authentication switch, so that the CPU sends the data packet to the authentication server for authentication processing. The invention can improve the processing speed of the message and lighten the load of the authentication server.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a message processing method, device and switch. Background technique [0002] The current network topology for three-tier authentication for users is as follows: figure 1 As shown, an egress authentication server is set between the egress device and the layer-3 core authentication device. The layer-3 core device is responsible for forwarding data packets from users accessing the external network to the egress authentication server. The network data message judges whether the user is an authenticated user. If it is an authenticated user, the data message will be forwarded to the egress device to allow the user to access the external network. Otherwise, the egress authentication server will After the data packet is authenticated, the user is allowed to access the external network. [0003] However, the above-mentioned authentication server utilizes the CPU therein to process the...
