Goes into standby mode and does not forward traffic. If the primary link shuts down, the standby link starts forwarding traffic. At any given time, only one of the interfaces is in the linkup state and forwarding When one of the links is up and forwarding traffic, the other link is in standby mode, ready to begin forwarding On devices, the Flex Links can be on the same device or on another device in the stack. You configure Flex Links on one Layer 2 interface (the active link) by assigning another Layer 2 interface as the Flex Links If the device is running STP, Flex Links are not necessary because STP already provides link-level redundancy or backup. Typically configured in service provider or enterprise networks where customers do not want to run STP on the device. Users can disable STP and still retain basic link redundancy. Solution to the Spanning Tree Protocol (STP). Information About Flex Links and MAC Address-Table Move Updateįlex Links are a pair of a Layer 2 interfaces ( device ports or port channels) where one interface is configured to act as a backup to the other. Sure that there are no loops in the configured topology. VLANs present on the port are configured for STP. A Flex Links port does not participate in STP, even if the However, you should configure both Flex Links with similarĬharacteristics so that there are no loops or changes in behavior if the The port channel or the physical interface as the active link.ĭoes not have to be the same type (Gigabit Ethernet or port channel) as theĪctive link. Two port channels (EtherChannel logical interfaces) as Flex Links, and you canĬonfigure a port channel and a physical interface as Flex Links, with either Links can be a port that belongs to an EtherChannel. An active link cannot belong to another Flex Links pair. An interface can be a backup link for only Supported only on Layer 2 ports and port channels.Ĭonfigure only one Flex Links backup link for any active link, and it must be aĭifferent interface from the active interface.īelong to only one Flex Links pair.
