STP

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.
The Switch supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol
(RSTP) as defined in the following standards.
⚫
IEEE 802.1D Spanning Tree Protocol
⚫
IEEE 802.1w Rapid Spanning Tree Protocol
The Switch uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allows faster
convergence of the spanning tree than STP (while also being backwards compatible
with STP-only aware bridges). In RSTP, topology change information is directly
propagated throughout the network from the device that generates the topology
change. In STP, a longer delay is required as the device that causes a topology change
first notifies the root bridge and then the root bridge notifies the network. Both RSTP
and STP flush unwanted learned addresses from the filtering database.
In STP, the port states are Blocking, Listening, Learning, Forwarding.
In RSTP, the port states are Discarding, Learning, and Forwarding.
Note: In this document, "STP" refers to both STP and RSTP.
STP Terminology
⚫
The root bridge is the base of the spanning tree.
⚫
Path cost is the cost of transmitting a frame onto a LAN through that port.
The recommended cost is assigned according to the speed of the link to
which a port is attached. The slower the media, the higher the cost.
