Switch Meshing
Switch Meshing Fundamentals
N o t e • A switch mesh domain (figure 5-1 on page 5-2) cannot include either
a switch that is not configured for meshing, or a hub.
• Where a given pair of switches are linked with meshed ports, you must
not also link the pair together through non-meshed ports unless you
have also enabled STP, RSTP, or MSTP to prevent a loop from forming.

Switch 1
Switch 2
Switch Mesh
Domain
This topology forms a
broadcast loop unless
you configure MSTP
on the network.
Figure 5-4. Example of an Unsupported Topology
• The switch blocks traffic on a meshed port connected to a non-
meshed port on another switch.
• Switch meshing does not allow trunked links (LACP or Trunk)
between meshed ports.
Linking a non-mesh device or port into the mesh causes the meshed switch
port(s) connected to that device to shut down.
Using a Heterogeneous Switch Mesh
You can use the switches covered in this guide with the ProCurve Series 5300xl
switches in normal mode.
