Abstract
A packet relay device determines a port to be placed on standby in a link aggregation, determines whether there is an active port among ports belonging to redundant network interfaces, and, if a network interface has no active port, places the network interface on standby. The packet relay device monitors whether a failure has occurred in an active network interface and, if a failure is detected, activates a standby network interface and places the failed network interface on standby.
