Configuration notes
•
Changing the STP state of the primary port in a trunk group affects all ports in the trunk group.
•
With RSTP, rapid convergence will not occur on ports connected to shared media devices, such
as hubs. To take advantage of the rapid convergence provided by RSTP, make sure to explicitly
configure all point-to-point links in a topology.
This command shows how to explicitly configure an interface which is attached to a LAN
segment at the end of a bridged LAN or to an end node.
Console(config)# interface ethernet 1/5
Console(config-if)# spanning-tree edge-port
