Setting Spanning Tree Protocol
Parameters
To set the STP bridge parameters for the switch,
1. Choose Spanning Tree Algorithm Parameters from the main menu.
2. Choose Protocol Parameters from the Spanning Tree Algorithm
Parameters menu.
3. The Protocol Parameters menu displays the current status of the
Spanning Tree Algorithm’s operation on the DES-2218, and allows
you to change several of the bridge parameters. All of these settings
are described below.
