AN ACCESS CONFIGURATION METHOD FOR THE LINK AGGREGATION AND A LINK AGGREGATION SYSTEM

摘要

An access configuration method for the link aggregation and a link aggregation system. The n ports of the access side is set to a link aggregation group, where the unique MAC address is assigned to each port (S102); The m IP addresses are configured to the link aggregation group(S104); The m IP addresses are bound with the n ports so that the difference between the number of the IP address bound with each port and the number of the IP address bound with any other port is less than or equal to 1(S106); Each port sends the ARP message including the corresponding relationship between the assigned IP address of the port and the MAC address of the port(S108). When the connection of the port interrupts, the IP address assigned originally to the interrupted port is floated to the other effective ports. After the interrupted port is normal, the corresponding port is floated to the interrupted port. The floating principle is the difference between the number of the IP address bound with each effective port and the number of the IP address bound with any other effective port is less than or equal to 1. After floating, each effective port sends the ARP message and renovates the corresponding relationship between the IP address and the MAC address.
