2.2 STP

2.2.1 STP

Feature Overview

The STP feature is a link management protocol that provides path redundancy while preventing un-

desirable loops in the network that are created by multiple active paths between stations.The STP

feature enables you to form a loop free network topology. Depending upon the path cost and the

priority of the ports and bridges, the STP selects a bridge as a root bridge and forms a loop-free log-

ical topology, which ensures a single path between any two-end stations.

STP in cnMatrix

Standards

The STP functionality is realized in the network using one of the three following STPs:

■ RSTP (802.1w)

■ MSTP (802.1s)

■ PVRST

Scaling Numbers

■ A maximum of 32PVRST instances can be configured in PVRST mode.

■ A maximum of 8 MSTP instances can be configured in MSTP mode.

Limitations

■ 802.1d standard is supported only in compatibility mode which allows cnMatrix to interact

with legacy bridges who supports legacy STP feature.

Default Values

■ The STP feature is enabled by default in RSTP mode.
