16.1.1 Overview

Uplink redundancy enables duplexed uplink ports on the Switch.If a link failure occurs during communication, the standby port takes over for the current port to continue communication with upstream switches. By using uplink redundancy, you can create redundant uplink ports without using complex protocols such as Spanning Tree Protocols. The two ports for redundancy are called uplink ports.

The following figure shows the basic configuration of uplink redundancy.

Figure 16-1: Basic configuration for uplink redundancy

When you use uplink redundancy in this configuration, if the link between the Switch and upstream switch A fails, the link between the Switch and upstream switch B can take over to continue communication.
