Configuration directions for example:
Enable RSTP function to avoid broadcast storm caused by looped network structure among
Switch A, Switch B and Switch C 1-10 port.
• Enable Switch A, B, C RSTP function
• Enter 1-10 within the Port Range (or click the box in front of each port) Equipment Priority,
cycle of sending message, maximum lifetime of information, default port status migration
delay
• Path Cost, enter “0” - automatically detected
• Port Priority, choose 128
• Point to Point (P2P), choose “yes”
• Edge Port, choose “no”
• Click <Save>, operation finished.
After setting RSTP, click “RSTP information” to check root bridge and port information. The port
recover time is around 30s by default, click right key to refresh current status.

PARAMETER
DESCRIPTION
DEVICE PRIORITY
As the network bridge priority, network bridge and network bridge MAC
address combined as bridge ID, of which the minimum bridge ID will become
the network root.
SENDING MESSAGE
INTERVAL
The interval needed send a BPDU data packet.
MAXIMUM
MESSAGE LIFETIME
Means the validity of a BPDU data package of a switch received from another
switch.
CHANGING PORT
STATUS DELAY
The forward delay of a switch port status in transition status (listening and
learning).
PATH EXPENDITURE
Setting port path cost, only setting only set when port default path cost on
“OFF” status. Port link cost, with port priority and port ID form port ID to
compare value range 1 ~ 200000000 “0” means automatic check.
PORT PRIORITY
The priority of the port in the network bridge, with port priority and port ID form
port ID to compare.
Default Port Priority: 128.
POINT TO POINT
PORT
Switch port and switch connected directly - Then this port is P2P port. RSTP
adopts negotiation mechanism for P2P port so as to achieve quick
transformation of port status.
EDGE PORT
The network edge switch generally connects with terminal equipment such as:
a PC or workstation. To configure these terminal ports to Edge Ports you can
achieve status of transformation port without discarding Learning and
Forwarding Transformation Course.
RSTP INFORMATION
Check RSTP information and port information
