Using A Heterogeneous Switch Mesh - HP 3500 Series Advanced Traffic Management Manual

Switch Meshing
Switch Meshing Fundamentals

4-6
If GVRP is enabled, meshed ports in a switch become members of any
■
dynamic VLANs created in the switch in the same way that they would if
meshing was not configured in the switch. (For more on GVRP, refer to
chapter 2, "GVRP".)
• A switch mesh domain (figure 4-1 on page 4-1) 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.
This topology forms a
broadcast loop unless
you configure MSTP
on the network.
Figure 4-4. 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 HP Series 5300xl
switches in normal mode.
