Abstract

The invention discloses a port configuration method and exchange equipment, wherein the method is applied in an exchange equipment which enables IGMP Snooping, and comprises receiving neighbor information of a link layer discovery protocol LLDP transmitted by a neighbor device through a port, judging whether the neighbor device enables the IGMP Snooping or not according to the LLDP neighbor information received by the port, and doing dynamic router port configuration to the port when the neighbor device enables the IGMP Snooping. The exchange equipment can lead multicast flow to be rapidly contracted through the IGMP Snooping information of an expanded LLDP information carrying device according to an expanded LLED information dynamic configuration router port when network topology is changed, manual configuration of users is avoided under the circumstance that the port is allocated with a plurality of VLANs, and the exchange equipment is convenient to maintain.

Description

technical field

[0001] The invention relates to the field of network technology, in particular to a port configuration method and switching equipment. Background technique

[0002] At present, in the metropolitan area network or enterprise network of multicast application, there is a common layer-2 network topology. In order to ensure the reliability of the network, the layer-2 network generally adopts MSTP (Multiple Spanning Tree Protocol, Multiple Spanning Tree Protocol) or RRPP (Rapid Ring Protection Protocol, fast ring network protection protocol) to selectively block redundant network links to achieve the purpose of eliminating network layer 2 loops, and at the same time back up the links. In addition, in Layer 2 forwarding, in order to prevent multicast traffic from spreading, Layer 2 switches will configure IGMP Snooping (Internet Group Management Protocol, Internet Group Management Protocol snooping) function to establish Layer 2 multicast forwarding tables, and conf...
