Switch Meshing
Operating Notes for Switch Meshing
Spanning Tree Operation with Switch Meshing
Using STP or RSTP with several switches and no switch meshing configured
can result in unnecessarily blocking links and reducing available bandwidth.
For example:
Switch
Mesh
Domain
Problem:
STP enabled and creating
traffic bottlenecks.
Solution:
Enabling meshing on links between
switch ports removes STP blocks on
meshed redundant links.

= STP, RSTP, or MSTP Blocking a Redundant Link
Figure 7-17. Example Using STP Without and With Switch Meshing
If you enable STP, RSTP, or MSTP on any meshed switch, you should enable
the same spanning-tree protocol on all switches in the mesh. (That is, if you
are going to use spanning-tree in a switch mesh, all switches in the mesh
should be configured with the same type of spanning-tree: 802.1d/STP,
802.1w/RSTP, or 802.1s/MSTP.) Spanning-Tree interprets a meshed domain
as a single link. However, on edge switches in the domain, STP and RSTP will
manage non-meshed redundant links from other devices. For example:
