RSTP configuration example

This section provides steps to configure Rapid Spanning Tree on the G8000, using the Command-Line Interface (ISCLI).

Rapid Spanning Tree Protocol is the default setting on the G8000.

Configure Rapid Spanning Tree

Rapid Spanning Tree is the default Spanning Tree mode on the G8000.

1.Configure port and VLAN membership on the switch.

2.Set the Spanning Tree mode to Rapid Spanning Tree.
