Embodiment Construction

[0050] This application provides a data frame sending method and an access device, which are applied to a network where M-LAG is deployed at the convergence layer. By defining a sub-LAG on the access device, the sub-LAG only includes the access device and A physical link between aggregation devices, the firewall connected to this aggregation device is in working state, and the north-south traffic reaching the access device is only forwarded to the aggregation device through the physical link contained in the sub-LAG, thus optimizing the north-south traffic The transmission path ensures that the north-south traffic accessing the external network does not pass through the peer-link between aggregation devices, and also reduces the bandwidth pressure of the peer-link.

[0051] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and various embodiments.

[0052] The data frame sending method provided by this applic...

Abstract

The invention discloses a data frame sending method and access equipment. The data frame sending method and the access equipment are applied to a network with a deployed M-LAG on a convergence layer, a sub LAG is defined on the access equipment, and the sub LAG only contains a physical link between the access equipment and one convergence equipment, wherein a firewall connected with the convergence equipment is in a working state; the north-south traffic arriving at the access equipment is forwarded to the convergence equipment only through the physical link contained in the LAG, thereby optimizing a transmission path of the south-north traffic, guaranteeing that the north-south traffic accessing the external network cannot pass through the peer-link between the convergence equipment, and reducing the bandwidth pressure of the peer-link.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for sending a data frame and an access device. Background technique [0002] Cross-device link aggregation group (English: multi-chassis link aggregation group, referred to as: M-LAG) is a mechanism to realize cross-device link aggregation, and perform cross-device link aggregation between one device and two other devices . The two devices that make up the M-LAG have independent control planes and management planes, can be upgraded independently, and are easy to maintain. [0003] Usually, the M-LAG is deployed at the aggregation layer to realize the acyclic network between the aggregation device and the access device, thus replacing the Spanning Tree Protocol (English: Spanning Tree Protocol, STP for short). [0004] An M-LAG deployment solution is as follows: figure 1 As shown: the aggregation devices DS1 and DS2 form an M-LAG system, and the M-LAG sys...
