4.2.7 RSTP
In switches, bridges and routers. The protocol allows a switch to communicate with other
RSTP compliant switches, and to ensure only one path existing between two stations in
your network environment.
The switch allows you to create multiple STP configurations and assign ports to a specific
tree.
Function name:
RSTP System Configuration
Function description:
This screen is used to display the RSTP system configuration and set the need of
parameters.
Parameter description:
System Priority:
System 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. Select a vale from the drop-down list
box.
The lower the numeric value you assign, the higher the priority for this system.
Default: 32768
Hello Time:
This is the time interval in seconds between BPDU configuration message
generations by the root switch. The allowed range is 1 to 10 seconds.
Default: 2
Max Age:
This is the maximum time a switch can wait without receiving a BPDU before
attempting to reconfigure. The allowed range is 6 to 40 seconds.
Default: 20
Forward Delay:
This is the maximum time (in seconds) a switch will wait before changing states.
The general rule: 2 * (Forward Delay – 1) >= Max Age >= 2 * (Hello Time + 1)
Default: 15
Force version:
Select RSTP or STP protocol from the drop-down list box.
