Smart Link Overview
In most cases, Spanning Tree Protocol (STP) is used to remove network loops while delivering link
redundancy in a dual uplink network. The problem with STP, however, is that STP convergence time is
long, which makes it not suitable for users who have high demand on convergence speed.
For more information about STP, refer to

.
Smart Link is a feature developed to address the slow convergence issue with STP. It provides link
redundancy as well as fast convergence in a dual uplink network, allowing the backup link to take over
quickly when the primary link fails. To sum up, Smart Link features the following:
