The following table describes the labels in this screen.
LABEL 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 hops.
Forward Delay Set the delay time an interface takes to coverage 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.
