Abstract

The embodiment of the invention discloses a message sending method and a switching chip, which relate to the field of communication, and can configure a queue of protocol messages sent to the CPU in a copy mode, so as to ensure the priority scheduling of the protocol messages. The message sending method includes: the switch chip receives the protocol message through the first port, and copies the protocol message to the destination port at the first port according to the first ACL rule, and the destination port is the switch The internal loopback port of the chip; the switching chip redirects the protocol message to the designated CPU queue of the CPU port according to the second ACL rule at the internal loopback port. The embodiment of the present invention is used for protocol message forwarding.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a message sending method and a switch chip. Background technique [0002] In the switch architecture, it is usually composed of a switching chip and a CPU (Central Processing Unit, central processing unit). The switching chip is responsible for forwarding data packets, and the CPU is responsible for management and control. CPU processing, such as L2 (layer 2, data link layer) management messages such as BPDU (bridge protocol data unit, bridge protocol data unit), GVRP (Generic Attribute Registration Protocol, general attribute registration protocol), ARP (Address Resolution Protocol, Address Resolution Protocol); L3 (layer 3, network layer) management messages such as RIP (Routing Information Protocol, routing information protocol), PIM (Protocol Independent Multicast, protocol independent multicast), OSPF (Open Shortest Path First, open shortest path Pri...
