MANAGED 8-PORT 10/100 + 2 G DUAL PERSONALITY SWITCH 2.5.2 RSTP System Configuration This screen allows the user to enter the RSTP parameters for the Switch. Please note: users must select "RSTP (802.1W)" under Bridge Configuration to perform this configuration. Otherwise, this option will not be accessible. Enter the appropriate values, then click on Apply to retain newly entered information or click on Undo to restore previously saved configurations. Parameter Description Bridge Priority Hello Time Set the bridge priority. The limit is given between 0 (the highest priority) and 65535 (the lowest priority). Bridge priority is used in selecting the root device, root port, and designated port. The device with the highest priority becomes the STA root device. However, if all devices have the same priority, the device with the lowest MAC address will then become the root device. Time interval (in seconds) at which the root device transmits a configuration message. The limit given is from 1 - 10 seconds. Forward Delay Set Forward Delay. The limit given is from 4~30 seconds. This is the maximum time (in seconds) the root device will wait before changing states (i.e., listening to learning to forwarding). Maximum age Set the (maximum age) waiting time for receiving packets before attempting to reconfigure the link. The limit given is from 6 - 40 seconds. 2.5.3 RSTP Per-Port Configuration STP/RSTP allows the Switch to assign a priority status to each of its ports, with respect to other networking nodes in the network. In other words, STP/RSTP determines the best route for data to flow, given the priority level of each node on the network. Ensure that this function is activated to avoid collisions and when setting up backup links. 15

Bridge priority is used in selecting the root device, root port, and
designated port. The device with the highest priority becomes the STA
root device. However, if all devices have the same priority, the device
with the lowest MAC address will then become the root device.
Time interval (in seconds) at which the root device transmits a

The limit given is from 1 – 10 seconds.
Set Forward Delay. The limit given is from 4~30 seconds. This is the
maximum time (in seconds) the root device will wait before changing
states (i.e., listening to learning to forwarding).
Set the (maximum age) waiting time for receiving packets before
attempting to reconfigure the link. The limit given is from 6 – 40

RSTP Per-Port Configuration
STP/RSTP allows the Switch to assign a priority status to each of its ports, with respect
to other networking nodes in the network. In other words, STP/RSTP determines the
best route for data to flow, given the priority level of each node on the network. Ensure
that this function is activated to avoid collisions and when setting up backup links.
