Chapter 23: STP and RSTP
Section IV: Spanning Tree Protocols 466
Enabling or Disabling a Spanning Tree Protocol
The AT-S62 software supports STP, RSTP, and MSTP. (MSTP is explained
in Chapter 24 on page 478.) Only one spanning tree protocol can be
active on the switch at a time. Before you can enable a spanning tree
protocol, you must first select it as the active spanning tree protocol on
the switch. After you have selected it as the active protocol, you can then
configure it and enable or disable it.
To select and activate a spanning tree protocol, or to disable spanning
tree, perform the following procedure:
1. From the Main Menu, type 3 to select Spanning Tree Configuration.
The Spanning Tree Configuration menu is shown in Figure 157.
Figure 157 Spanning Tree Configuration Menu
Note
Do not enable spanning tree on the switch until after you have
selected an activate spanning tree protocol and configured the
settings. To disable spanning tree, go to Step 5.
2. To change the active version of spanning tree on the switch, type 2 to
select Active Protocol Version.
The following prompt is displayed:
Enter new value (S-STP, R-RSTP, M-MSTP):
3. Type S to select STP, R to select RSTP, or M to select MSTP.
Note
A change to the active spanning tree is automatically saved on the
switch.
