Cross Chassis Stacking
Topology
Blade models: MXL, M8024-k, M6348,
M6248, IOA (using CLI)
Configuration
Blade switches are stacked vertically
so that there are two independent
stacking rings. Switches on the left
of the chassis form a ring and
switches on the right side of the
chassis form a ring. Independent
stack rings allow each ring to be
upgraded independently.
Note that IOA is limited to a two unit
stack. IOA has a simplified CLI
command for stacking and IOA
must be managed via CLI when
stacked.
