Two options are offered for choosing STP algorithm.
Compatible - STP (IEEE 802.1D)
Normal - RSTP (IEEE 802.1w)
Enabled to support port trunking in STP. It means a link aggregate is treated as a
physical port in RSTP/STP operation.
Port is enabled to support RSTP/STP.
An Edge Port is a port connected to a device that knows nothing about STP or RSTP.
Usually, the connected device is an end station. Edge Ports will immediately transit to
forwarding state and skip the listening and learning state because the edge ports
cannot create bridging loops in the network.
Specifies the path cost of the port that switch uses to determine which port are the
forwarding ports the lowest number is forwarding ports, the rage is 1 ~ 200,000,000
and Auto. Auto means a default cost is automatically calculated in RSTP operation
based on the port link speed.
The default costs are :
Link Speed Auto Default Cost
10Mbps 2000000
100Mbps 200000
1000Mbps 20000
