Switch Meshing
Switch Meshing Fundamentals
■ The spanning-tree configuration 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: 802.1D, 802.1w, or 802.1s.
■ 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.
■ If a switch in the mesh has a particular static vlan configured, then all
switches in the mesh must have that static vlan configured.
■ If a switch in the mesh has IGMP enabled, then all switches in the mesh
must have IGMP enabled.
■ If a switch in the mesh has LLDP enabled, then all switches in the mesh
must have LLDP 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:
Switch
Non-Mesh
Mesh Domain
Mesh Domain
Mesh Domain
Mesh Domain Non-Mesh Ports
Non-Mesh Ports
Non-Mesh Link
Figure 5-3. Example of Multiple Meshed Domains Separated by a Non-Mesh Switch or a Non-Mesh Link
■ 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 3, “GVRP”.)
