Spanning Tree Protocol Configuration
The following figures and tables describe the configuration of the Spanning Tree Protocol (STP) on the switch.
| Figure7- 34. STP Switch Settings Menu | |
Set the parameters listed below in the STP Switch Settings menu. | ||
|
| |
Spanning | Allows the STP to be globally Enabled or Disabled on the switch. Default = | |
Tree Protocol | Enabled. | |
| 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 | |
Max Age | 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 | |
| Default = 20Default = 20 | |
|
| |
Hello Time | The time interval (in seconds) at which the root device transmits a configuration | |
message. Default = 2 | ||
| ||
| 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 | forward packets. In addition, each port needs time to listen for conflicting | |
information that would make it return to a blocking state; otherwise, temporary | ||
Delay | data loops might result. | |
| Maximum value is 30 | |
| Minimum value is the higher of 4 or [(Max. Age / 2) +1] | |
| Default = 15 | |
|
| |
| Device priority used in selecting the root device, root port, and designated port. | |
Bridge | 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 | ||
Priority | ||
device with the lowest MAC address will become the root device. | ||
| ||
| Range 0 to 65535. Default = 32,768 |
