DESCRIPTION
Enabled
Select Enabled to use Spanning Tree Protocol (STP) or Rapid Spanning
Tree Protocol (RSTP). Select Disabled to not use STP or RSTP.
Force Version
Select the operating mode of STP.
 STP-Compatible: 802.1D STP operation.
 RSTP-Operation: 802.1w operation.
 MSTP-Operation: 802.1s operation.
Max Hops
Set the value of the maximum number of hops in the region. Enter a
number between 1 and 40 as the max number of hops.
Forward Delay
Set the delay time an interface takes to change from blocking state to
forwarding state.
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.
