Fast Forward
The value of the priority field which is contained in
the first (in network byte order) octet of the (2 octet
long) Port ID
The contribution of this port to the path cost of paths
towards the spanning tree root, which include this
port. 802.1D-1990 recommends that the default value
of this parameter be in inverse proportion to the speed
of the attached LAN
The device omits from the 4 steps
(Blocking-Listening-Learning-Forwarding) to 3 steps
(Blocking-Listening-Forwarding) for speeding up
