Spanning Tree Protocol Settings
State

Select Enabled to use Spanning Tree Protocol (STP) or Rapid Spanning 
Tree Protocol (RSTP).

Mode

Tree Protocol (RSTP). See

information on STP.

Bridge Parameters
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.
