State | Select Enabled to use Spanning Tree Protocol (STP) or Rapid Spanning |
| Tree Protocol (RSTP). |
|
|
Mode | Select to use either Spanning Tree Protocol (STP) or Rapid Spanning |
| Tree Protocol (RSTP). See Section 17.1 on page 95 for background |

|
Forward Time | This is the maximum time (in seconds) the Switch will wait before |
| changing states. This delay is required because every switch must |
| receive information about topology changes before it starts to forward |
| frames. 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. The allowed range is 4 to 30 |
| seconds. |
|
|
Max Age | This is the maximum time (in seconds) the Switch can wait without |
| receiving a BPDU before attempting to reconfigure. All Switch ports |
| (except for designated ports) should receive BPDUs at regular intervals. |
| Any port that ages out STP information (provided in the last BPDU) |
| becomes the designated port for the attached LAN. If it is a root port, a |
| new root port is selected from among the Switch ports attached to the |
| network. The allowed range is 6 to 40 seconds. |
|
|
Hello Time | This is the time interval in seconds between BPDU (Bridge Protocol Data |
| Units) configuration message generations by the root switch. The |
| allowed range is 1 to 10 seconds. |
