How to Enable RSTP
Introduction
The instructions, below, show you how to enable rapid spanning tree protocol
(RSTP) functionality for the STB NIP 2311 NIM. RSTP (based on IEEE 802.w) is a
layer 2 protocol that performs these important services:
z it creates a loop-free logical path connecting all network devices, and
z it automatically restores network communication, by activating redundant links, in
the event of a network failure
The NIM operates in daisy chain loops when its RSTP functionality is enabled.
Because of its redundant Ethernet connectors, the STB NIP 2311 is able to
communicate on the network even after communications to one of the ports are
interrupted.
In daisy chain loops, RSTP provides faster recovery times in the case of single
events (for example, a switch power-off or cable disconnection).
