RSTP Configuration, Continued…
Following the link for the view RSTP Port Configuration at VLAN# the administrator or user can see the current RSTP status of the ports on that VLAN. This will show information such as the Path Cost and the Port State. If the switch sees a redundant path it will put the port with the highest Path Cost into Blocking mode where it will discard packets coming in on that port. In the below example, P12 is a redundant port with port P2, therefore P2 is forwarding and P12 is discarding.
