Link aggregation management device, relay device, link aggregation management method and program

摘要

PROBLEM TO BE SOLVED: To facilitate replacement of stack constituent devices for which link aggregation is set. A link aggregation management device includes a state monitoring unit that detects a change in a stack constituent device that is virtually connected to a predetermined relay device using link aggregation and that operates as a single device, and the stack constituent device. And a relay device control unit for performing the setting of the link aggregation in the relay device and the setting of the link aggregation by the changed stack constituent device when the change is detected.
