The RSTP Configuration Page
Introduction
The STB NIP 2311 module includes a dual port Ethernet switch that you can
configure to support the rapid spanning tree protocol (RSTP). When RSTP is
enabled in all Ethernet network switches, this protocol can:
z create a loop-free logical path connecting all network devices
z automatically restore network communication (by activating redundant links) in
the event communication is lost on any part of the network
Use the RSTP configuration page to disable or enable RSTP for the STB NIP 2311
module:
Parameters:
Configuring RSTP
Follow these steps to configure RSTP after you have accessed the module’s
embedded web pages (see page 145):
Status z Enabled
z Disabled
Bridge Priority This value is used to determine which node is the root bridge. The node
with the lowest priority number is the root bridge. Schneider Electric
recommends an RSTP-enabled switch as the root bridge, not the STB
NIP 2311. Therefore, this value should be higher than the bridge
priority of the RSTP-enabled switch.
