Abstract

The present application discloses a method and device for processing the aging time of a MAC address table, and belongs to the technical field of communication. The method is applied to a layer-2 network device included in a layer-2 network, and includes: determining the aging time of a ARP table of a target layer-3 network device; changing the stored aging time information of the MAC address table to first aging time information based on the aging time of the ARP table, wherein the first aging time is greater than or equal to the aging time of the ARP table of the target layer-3 network device; transmitting the first aging time information to another layer-2 network device, other than layer-2 network device, in the layer-2 network in order that the another layer-2 network device changes the stored aging time information of the MAC address table to the first aging time information. The method and device avoids a situation that the aging time of the MAC address table of the layer-2 network device is less than the aging time of the ARP table of the layer-3 network device, so as to avoid network congestion and service loss.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for processing aging time of a Media Access Control (MAC) address table. Background technique [0002] The communication network is set according to the network level, and its network topology generally includes a layer 2 (Layer 2) network and a layer 3 (Layer 3) network. The layer 2 network and the layer 3 network can be interconnected through the gateway device of the layer 3 network. Among them, the second layer is also called the data link layer. The second layer network includes multiple cascaded layer two network devices. Each layer two network device forwards data based on the stored MAC address table. The MAC address table stores the MAC address and Correspondence between network device port numbers. Layer 3 is also called the network layer. The Layer 3 network includes multiple cascaded Layer 3 network devices. Each Layer 3 net...
