Spanning Tree Parameters

When you connect two or more networks to increase the

Network 1

number of users, or enhance the ability for users of two (or

more) networks to communicate with one another, you can

control the routing of data to maximize the efficiency of the

traffic between the networks.

Bridging characteristics allow you to route

necessary messages between two networks

Network 2

and to eliminate unnecessary traffic to other

networks when messages are only intended

for use within the local network.

Network 3

Furthermore, you can set up redundant paths for bridging,

which reduces the potential for data path losses due to bridging

network outages. You can establish a path redundancy for bridging

networks and redundancy for ports on the same

bridging network.

Path redundancy creates a loop by means of which data packets can potentially travel indefinitely if the bridge root network were unable to dynamically “prune” pathways between each network. TheS PANNING TREE PARAMETERS PAGE allows you to set configuration items that allow the establishment of the root, redundancy of root networks, redundancy of root network ports to other networks, and dynamic pruning between network loops.
