–
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 (0-65535) — Specifies the bridge priority value. When switches or bridges are running STP, each is
assigned a priority. After exchanging BPDUs, the device with the lowest priority value becomes the Root
Bridge. The default value is 32768. The port priority value is provided in increments of 4096.
•
Hello Time (1-10) — Specifies the device Hello Time. The Hello Time indicates the amount of time in sec-
onds a Root Bridge waits between configuration messages. The default is 2 seconds.
•
Max Age (6-40) — Specifies the device Maximum Age Time. The Maximum Age Time is the amount of time
in seconds a bridge waits before sending configuration messages. The default Maximum Age Time is
20 seconds.
•
Forward Delay (4-30) — Specifies the device Forward Delay Time. The Forward Delay Time is the amount of
time in seconds a bridge remains in a listening and learning state before forwarding packets. The default is 10
seconds.
•
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 day-hour-minute-second for-
mat, such as 2 days 5 hours 10 minutes and 4 seconds.
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.
