Path Cost Default Values. Specifies the method used to assign default path costs to STP ports. The possible
field values are:
Short - Specifies 1 through 65,535 range for port path costs. This is the default value.
Long - Specifies 1 through 200,000,000 range for port path costs.
The default path costs assigned to an interface vary according to the selected method.
Ethernet - 2,000,000
Fast Ethernet - 200,000
Gigabit Ethernet - 20,000
The default values for short path costs are:
Ethernet - 100
Fast Ethernet - 19
Gigabit Ethernet - 4
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. For example, 4096, 8192,
12288, etc.
Hello Time (1-10). The Hello Time indicates the amount of time in seconds a root bridge waits between
configuration messages. The default is 2 seconds.
Max Age (6-40). Specifies the Maximum Age Time. The Maximum Age Time indicates the amount of time in
seconds a bridge waits before sending configuration messages. The default max age is 20 seconds.
Forward Delay (4-30). Specifies the forward delay time. The Forward Delay Time indicates the amount of time in
seconds a bridge remains in a listening and learning state before forwarding packets. The default is 10 seconds.
Designated Root. The information listed indicates the ID of the bridge, which is the root of the selected instance.
