Configuring Flex Link

Flex Links are a pair of a Layer 2 interfaces (switchports or port channels), where one interface is configured
to act as a backup to the other.
This feature provides an alternative solution to the Spanning Tree Protocol (STP), allowing users to turn off
STP and still provide basic link redundancy. You generally configure Flex Links in networks where customers
do not want to run STP on the switch. When you configure STP on the switch, it is not necessary to configure
Flex Links because STP already provides link-level redundancy or backup.

For more information about flex links, see the Cisco Nexus 9000 Switch NX-OS Layer 2 Switching Configuration Guide.
