Configuring Spanning Tree
Defining Classic Spanning Tree
–Short — Specifies 1 through 65,535 range for port path cost. This is the default value.
–Long — Specifies 1 through 200,000,000 range for port path cost. The default path cost assigned to an interface varies according to the selected method (Hello Time, Max Age, or Forward Delay).
•Priority
•Hello Time
•Max Age
20 seconds.
•Forward Delay
•Bridge ID — Identifies the Bridge priority and MAC address.
•Root Bridge ID — Identifies the Root Bridge priority and MAC address.
•Root Port — Indicates the port number that offers the lowest cost path from this bridge to the Root Bridge. This field is significant when the bridge is not the Root Bridge. The default is zero.
•Root Path Cost — The cost of the path from this bridge to the Root Bridge.
•Topology Changes Counts — Specifies the total amount of STP state changes that have occurred.
•Last Topology Change — Indicates the amount of time that has elapsed since the bridge was initialized or reset, and the last topographic change that occurred. The time is displayed in a
2.Select Enable in the Spanning Tree State field.
3.Select an STP type in the STP Operation Mode field.
4.Define the BPDU Handling and Path Cost Default Values fields.
5.Select either the Hello TIme, Max Age, or Forward Delay field.
6.Click . STP is enabled, and the device is updated.
