Enabling or Disabling Spanning Tree

The AT-S88 management software supports STP and RSTP. However,

only one spanning tree protocol can be active on the switch at a time.

To select and activate a spanning tree protocol, or to disable spanning

tree, perform the following procedure:

1. From the main menu, select Bridge > Spanning Tree.

The Spanning Tree page is shown in Figure 35.

Figure 35. Spanning Tree Page

The top portion of the page displays the following information:

Root Port

The root port of the root bridge.

Root Port Path Cost

The spanning tree algorithm uses the cost parameter to decide which

port provides the lowest cost path to the root bridge for that LAN. The

range is 0 to 61,440. The default setting is Automatic Update, which

sets port cost depending on the speed of the port. The Auto default

values are shown in Table 5 on page 98.
