RSTP – 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, B1 is a
redundant port with port A2, therefore A2 is forwarding and B1 is discarding.
