Modifying the stack topology
You can increase the efficiency and redundancy
of the stack by adding stacking cables to create a stacking mesh instead
of a ring. This modification can be performed while the switches are
powered on and the stack is operating. After connecting the cables,
enter the show stack
command. The Stack
Topology field
value displays the new topology.
NOTE:
Transitioning between mesh and ring topologies temporarily leaves the stack in an unsupported state (for example, when the stack is only connected to half of the additional ports). If a failure occurs during this time, redundancy is not guaranteed.
