STP Status

Click STP Status to display the IES-708-22A’s STP status (see

Section 23.2 on

page 171

).

Active

Select this check box to turn on RSTP.

Note: It is recommended that you only use STP when you use the

IES-708-22A in standalone mode with a network topology
that has loops.

Bridge Priority

Bridge priority is used in determining the root switch, root port and designated

port. The switch with the highest priority (lowest numeric value) becomes the

STP root switch. If all switches have the same priority, the switch with the lowest

MAC address will then become the root switch. The allowed range is 0 to

61440.
The lower the numeric value you assign, the higher the priority for this bridge.
Bridge Priority determines the root bridge, which in turn determines Hello Time,

Max Age and Forwarding Delay.
