Enabling or Disabling STP and RSTP
The AT-8400 Series switch can support STP, RSTP, and MSTP. However,
only one spanning tree protocol can be active on the switch at a time.
Before you enable a spanning tree protocol, you must first select it as the
active spanning tree protocol on the switch. Once you have selected it as
the active protocol, you can enable or disable it.
To select the active spanning tree protocol and to enable or disable it,
perform the following procedure:
Note
Changing the active spanning tree protocol resets the switch.
1. From the Main Menu, type 3 to select Spanning Tree Menu.
The Spanning Tree Menu is shown in Figure 74.
