Enabling STP, RSTP, or MSTP
The AT-8400 Series switch can support the three spanning tree protocols
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.
Once selected, 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 Home Page, select Configuration.
The Configuration System page is displayed with the General tab
selected by default, as shown in Figure 155 on page 434.
2. From the Configuration menu, select the Layer 2 option.
The Layer 2 page is displayed with the MAC Address tab selected
by default, as shown in Figure 204 on page 541.
3. Select the Spanning Tree tab.
