amount of time the root has waited during sending hello messages.
Forward Delay Time (4-30): Enter a value between 4 and 30 seconds. This value is the
time that a port waits before changing from Spanning Tree Protocol learning and listening
states to forwarding state.
This is the amount of time of the Managed Switch will wait before checking to see if it
should be changed to a different state.
Once configuration setting is completed, click on Apply to apply your settings.
Caution: The rule to configure Hello Time, Forwarding Delay, and Max Age parameter, is
highly recommended to follow.
2 × (Forward Delay Time – 1 sec) ≥ Max Age Time ≥ 2 × (Hello Time value + 1 sec)

STP Port Configuration
To configure the port parameter,
it is required that STP or RSTP is
enabled and taken effectively.
Port Configuration
Select the port being configured
then current settings and status
of the port are visible on the
screen.
Path Cost: Enter a number
between 1 and 200,000,000. This
value of the path “cost”
is
the
shortest path of the port
selected to the root bridge.
The slower the interface, the higher the cost is. The path with the lowest cost
will be used to reach the root bridge.
of the path to the other bridge from the
transmitting bridge at the specified port.
Priority: Enter a value between 0 and 240, using multiples of 16. This is the value that
decides which port should be blocked by priority in a LAN.
Link Type: There are 3 link types for your selection-Auto, P2P and Share.
Some of the rapid state transitions that are possible within RSTP depend upon whether the
port of concern can only be connected to another bridge (i.e. it is served by a point-to-point
LAN segment), or if it can be connected to two or more bridges (i.e. it is served by a
shared-medium LAN segment). This function allows link status of the link to be manipulated
administratively. “Auto” means to auto select P2P or Share mode. “P2P” means P2P is
enabled; the 2 ends work in full duplex mode. While “Share” is enabled, it means P2P is
disabled; the 2 ends may connect through a share media and work in half duplex mode.
Edge Port: A port directly connected to the end stations cannot create a bridging loop in
the network. To configure this port as an edge port, set the port to the Enable state. When
the non-bridge device connects an admin edge port, this port will be in blocking state and
turn to forwarding state in 4 seconds.
