Upgrading to RSTP

To ensure that your network is not disrupted when you upgrade the switch from v5.x application software to v6.0 or later, RSTP has the following settings:

• The default setting for Spanning Tree version is common Spanning Tree.
• Switch ports for which fast start was enabled are set as edge ports. In v6.0 and later, the fast start feature is replaced with the ability to set switch ports as edge ports. For information on setting switch ports as edge ports, see "Configuring Spanning Tree Settings for Switch Ports" later in this chapter.
• All settings for port priorities and path costs are preserved.
