Flex Links is a layer 2 switch feature with which we can achieve redundancy and load balancing at Layer 2 level, as an alternative to Spanning Tree Protocol (STP). Flex links are a pair of Layer 2 interfaces, such as switch ports or port channels, where one interface is configured as a backup to the other. When the primary link goes down the backup link takes over traffic forwarding.

- Flex Links is a layer 2 switch feature with which we can achieve redundancy and load balancing at Layer 2 level, as an alternative to Spanning Tree Protocol (STP). Flex links are a pair of Layer 2 interfaces, such as switch ports or port channels, where one interface is configured as a backup to the other. When the primary link goes down the backup link takes over traffic forwarding. They can be configured on all switches that need redundancy, but typical place for them are in service provider or enterprise networks where customers do not want to run STP on the switch. Flex Link Examples: Scenario 1: A Downlink Switch with one primary Uplink and a backup Uplink switches. Scenario 2: Back to Back connected Switches with redundant connections.
