Switch Meshing
Operating Notes for Switch Meshing
Requirements and Restrictions
â– Supported Mesh Domain Size:
• In a partially interconnected mesh domain, where there is not a
direct connection from every meshed switch to every other meshed
switch, the recommended maximum is 12 switches. Figure
7-21 shows
a meshed backbone with the maximum supported switch count in a
partially interconnected mesh domain.
• In a fully interconnected mesh domain, where there is a direct
connection from every meshed switch to every other meshed switch,
the recommended maximum is five switches. Figure
7-22 shows a
fully interconnected mesh.

Switches SW 1 through SW 12

mesh domain.

Note that more than one
link is allowed between
any two switches in the
domain.
As shown here, meshing
allows multiple redundant
links between switches in
the domain.
Note also that a switch
can have up to 24 ports
configured for meshing.
