The
Spanning Tree Summary Page
contains the following fields:

values are:
■
Enabled
— Indicates that STA is enabled on the port.
■
Disabled
— Indicates that STA is disabled on the port.
■
Path Cost
— Indicates the port contribution to the root path cost. The
path cost can be adjusted to a higher or lower value, and is used to
determine the path used to forward traffic when a path is re-routed.
■
Edge Port
— Indicates if fast forwarding is enabled on the port. If
enabled, the port is automatically placed in the

reconfiguration events, does not cause the spanning tree to
