Path Cost
Path cost is the cost of transmitting a frame on to a LAN through that port. It is
recommended to assign this value according to the speed of the bridge. The slower the
media, the higher the cost-see

Configuration
Click Configuration to specify which STP mode you want to activate. Click RSTP to edit
RSTP settings on the Switch.
Bridge
Root refers to the base of the spanning tree (the root bridge). Our Bridge is this switch.
This Switch may also be the root bridge.
Bridge ID
This is the unique identifier for this bridge, consisting of bridge priority plus MAC address.
This ID is the same for Root and Our Bridge if the Switch is the root switch.
Hello Time
(second)
This is the time interval (in seconds) at which the root switch transmits a configuration
message. The root bridge determines Hello Time, Max Age and Forwarding Delay.
Max Age (second)
This is the maximum time (in seconds) the Switch can wait without receiving a
configuration message before attempting to reconfigure.
