Configuring Flex Links and the MAC

Address-Table Move Update Feature

Note To use Flex Links and the MAC address-table move update feature, the switch must be running the LAN

Base image.

This chapter describes how to configure Flex Links, a pair of interfaces on the Catalyst 2960, 2960-S,

or 2960-C switch that provide a mutual backup. It also describes how to configure the MAC

address-table move update feature, also referred to as the Flex Links bidirectional fast convergence

feature. Unless otherwise noted, the term switch refers to a standalone switch and to a switch stack.

Note Stacking is supported only on Catalyst 2960-S switches running the LAN base image.
