Rapid Spanning Tree of concepts:
Switch priority
：
As the bridge priority
，
the bridge priority and bridge MAC address combine bridge
ID
，
the smallest ID bridge will become the root bridge on the network.
Polling interval
：
how often send BPDU packet at one time.
Forwarding delay
：
the port state of switch remain a forward delay time over the listening and learning.
The maximum aging time
：
after one switch receive a packet from other switches , how long the packet
is valid.
The port concepts of RSTP
:
Port path overhead
：
port link cost compared with port priority and port ID .
Port priority
：
port priority among the net bridge compared with port priority and port ID
Point to point network connection
：
directly connect with switches port each other ,the port is
P2P,which adopted negotiation mechanism,RSTP can achieve port state rapid conversion RSTP
