Enabling or Disabling STP, RSTP, or MSTP
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. So
before you can 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 then 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 67.

Note
If you do not want to change the active spanning tree protocol and
just want to enable or disable it, go to step 6.
2. To change the active version of spanning tree protocol on the switch,
type 2 to select Active Protocol Version.
The following prompt is displayed:
This operation will need a reboot of the system.
