The Redundant Pairs feature enables you to create redundant links in networks that do not use STP by configuring backup interfaces for the interfaces on either side of the primary link. Note: For details on STP, refer to Chapter 46, "Spanning Tree Protocol (STP)," on page 797. Assign a backup interface to an interface using the command switchport backup. The backup interface remains in down state until the primary fails, at which point it transitions to up state. If the primary interface fails, and later comes up, it becomes the backup interface for the redundant pair. FTOS supports Gigabit, 10-Gigabit, and 40-Gigabit interfaces as backup interfaces. You must apply all other configurations to each interface in the redundant pair such that their configurations are identical, so that transition to the backup interface in the event of a failure is transparent to rest of the network. 506 | Layer 2
