This section contains information about configuring the SBC 1000/2000 to operate within multiple spanning trees in a network.
...
A network topology of bridges typically contains redundant connections to provide alternate paths in case of link failures. Since there is no concept of time-to-live (TTL) in Ethernet frames, this could result in permanent circulation of frames if there are loops in the network. To prevent loops, a spanning tree connecting all the bridges is formed in real time. The standby/redundant ports are put in a discarding (non-forwarding) state. They are enabled when required.
