Switch Meshing
Switch Meshing Fundamentals
Spanning tree must be the same for all switches in the mesh (enabled or
disabled). If spanning tree is enabled in the mesh, it must be the same
version on all switches in the mesh (STP or RSTP).
If a switch in the mesh has GVRP enabled, then all switches in the mesh
must have GVRP enabled. Otherwise, traffic on a dynamic VLAN may not
pass through the mesh.
G VRP N o t e HP Procurve 1600M/2400M/2424M/4000M/8000M switches do not offer the
GVRP feature. If any of these switches are in your switch mesh, then GVRP
must be disabled on any Series 5300XL switches in the mesh.
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
“GVRP” on page 11-34.)
If a switch in the mesh has a particular static vlan enabled, then all
switches in the mesh must have that static vlan enabled.
If a switch in the mesh has IGMP enabled, then all switches in the mesh
must have IGMP enabled.
After adding or removing a port from the mesh, you must save the current
configuration and reboot the switch in order for the change to take effect.
Multiple meshed domains require separation by either a non-meshed
switch or a non-meshed link. For example:
