9 Spanning Tree
Redundant links are often used for link backup and network reliability in the Ethernet
switching network. However, such links will generate loops on the switching network, leading
to broadcast storm, unstable MAC address list and other faults, thus worsening users’
communication quality, or even interrupting the communication. As a result, STP (Spanning
Tree Protocol) appears.
Same with the development of other protocols, from the original STP defined in IEEE
802.1D, to RSTP (Rapid Spanning Tree Protocol) defined in IEEE 802.1W and to MSTP
(Multiple Spanning Tree Protocol) defined in IEEE 802.1S, STP keeps upgrading.
MSTP is compatible with RSTP and STP while RSTP is compatible with STP. The
contrast among these 3 protocols is shown in the table.

Characteristic Application
STP
A tree rid of loops as the solution
to broadcast storms and redundant
backups.
It converges slowly.
A tree rid of loops as the
solution to broadcast storms and
redundant backups.
It converges slowly.
RSTP
A tree rid of loops as the solution
to broadcast storms and redundant
backups.
It converges rapidly.
MSTP
A tree rid of loops as the solution
to broadcast storms and redundant
backups.
It converges rapidly.
Spanning trees balance the load among
VLANs. Flow of different VLANs will be
forwarded subject to paths.
Distinguish the user and business
flow for load sharing. Different
VLANs forward the flow through
separate spanning trees.
After STP is deployed, the following objectives can be achieved by calculating the
loops with topology:
● Loop elimination: eliminate possible communication loops by blocking redundant
links.
● Link backups: activate redundant links to restore network connectivity if the active
path fails.
9.1 Property
Configure STP global parameters. In specific network environment, STP parameters
of some devices must be adjusted to achieve the best performance.
