Switch Meshing 
Introduction 
Introduction 
Switch meshing is a load-balancing technology that enhances reliability and 
performance in these ways: 
■  Provides significantly better bandwidth utilization than either Spanning 
Tree Protocol (STP) or standard port trunking. 
■  Uses redundant links that remain open to carry traffic, removing any 
single point of failure for disabling the network, and allowing quick 
responses to individual link failures. This also helps to maximize invest-
ments in ports and cabling. 
■  Unlike trunked ports, the ports in a switch mesh can be of different types 
and speeds (10 and 100 Mbps, gigabit, and 10 gigabit). For example, a 
10Base-FL port and a 1GB port can be included in the same switch mesh.
