Figure 83 Spanning Tree Port Setup Page

The Spanning Tree Port Setup Page contains the following fields:

■Status — Specifies if STA is enabled on the port. The possible field values are:

■Enabled — Indicates that STA is enabled on the port.

■Disabled — Indicates that STA is disabled on the port.

■Edge Port — Specifies if fast forwarding is enabled on the port. If enabled, the port is automatically placed in the Forwarding state when the port link is up. Edge Port optimizes STA protocol topology convergence, retains the current forwarding database to reduce the amount of frame flooding required to rebuild address tables during reconfiguration events, does not cause the spanning tree to reconfigure when the interface changes state, and also overcomes other STA-related timeout problems. The possible field values are:

■Enabled — Enables edge port on the port.

■Disabled — Disables edge port on the port.
