5.4 STP/RSTP
(R)STP detects and breaks network loops and provides backup links between
switches, bridges or routers. It allows a switch to interact with other (R)STP -
compliant switches in your network to ensure that only one path exists between
any two stations on the network.
Note: In this user’s guide, “STP” refers to both STP and RSTP.
5.4.1 STP Terminology
The root bridge is the base of the spanning tree; it is the bridge with the lowest
identifier value (MAC address).
Path cost is the cost of transmitting a frame onto a LAN through that port. It is
assigned according to the speed of the link to which a port is attached. The slower
the media, the higher the cost - see the next table.
