The following fields can be set:
Parameter | Default | Description |
Status:<Enabled> Enabled
Max Age | 20 |
Hello Time | 2 |
Forward Delay | 15 |
Allows the STP to be globally Enabled or Disabled on the switch.
The maximum time (in seconds) a device can wait without receiving a configuration message before attempting to reconfigure. All device ports (except for designated ports) should receive configuration messages at regular intervals. Any port that ages out STP information (provided in the last configuration message) becomes the designated port for the attached LAN. If it is a root port, a new root port is selected from among the device ports attached to the network.
The minimum value is the higher of 6 or [2 x (Hello Time +1)].
The maximum value is the lower of 40 or [2 x (Forward Delay
The time interval (in seconds) at which the root device transmits a configuration message.
The maximum time (in seconds) the root device will wait before changing states (i.e., from the listening to learning to forwarding). This delay is required because every device must receive information about topology changes before it starts to forward packets. In addition, each port needs time to listen for conflicting information that would make it return to a blocking state; otherwise, temporary data loops might result.
Maximum value is 30
Minimum value is the higher of 4 or [(Max. Age / 2) +1]
Priority | 32,768 | Device priority used in selecting the root device, root port, |
|
| and designated port. The device with the highest priority |
|
| becomes the STP root device. The lower the numeric |
|
| value, the higher the priority. If all devices have the same |
|
| priority, the device with the lowest MAC address will |
|
| become the root device. |
|
| Range 0 to 65535. |
STP Group | Default | Allows the selection of one of the STP Groups previously |

| configured on the switch |
