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.


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.
