Method and system of updating conversation allocation in link aggregation

摘要

A method of updating conversation allocation in link aggregation is disclosed. The method starts with verifying that an implementation of a conversation-sensitive link aggregation control protocol (LACP) is operational at a network device of a network for an aggregation port. Then it is determined that operations through enhanced link aggregation control protocol data units (LACPDUs) are possible. The enhanced LACPDUs can be used for updating conversation allocation information, and the determination is based at least partially on a compatibility check between a first set of operational parameters of the network device and a second set of operational parameters of a partner network device. Then a conversation allocation state of an aggregation port of the link aggregation group is updated based on a determination that the conversation allocation state is incorrect, where the conversation allocation state indicates a list of conversations transmitting through the aggregation port.

1. A method implemented by a network device for updating conversation allocation over links of a link aggregation group, wherein the network device is communicatively coupled with aggregation ports through the links of the link aggregation group, the method comprising:
verifying that an implementation of a conversation-sensitive link aggregation control protocol (LACP) is operational, wherein the conversation-sensitive LACP coordinates conversation-sensitive frame collection and distribution of the network device and a partner network device, and wherein the partner network device is a remote network device of the link aggregation group communicatively coupled with the network device; determining that operations through enhanced link aggregation control protocol data units (LACPDUs) are possible, wherein the determination is based at least partially on a compatibility check between a first set of operational parameters of the network device and a second set of operational parameters of the partner network device; and updating a first conversation allocation state of an aggregation port of the link aggregation group based on a determination that the first conversation allocation state is incorrect, wherein the first conversation allocation state indicates a first list of conversations transmitting through the aggregation port, and wherein updating the first conversation allocation state of the aggregation port of the link aggregation group includes:
receiving one or more enhanced LACPDUs from the partner network device indicating a partner conversation allocation state different from the first conversation allocation state; andupdating the first conversation allocation state through an updating function.
