Stack construction method 2: Manual configuration
Description
With this method, users should configure every unit individually and enable stacking on each unit.
Once the units are connected together, they automatically form a stack. With this method, the unit with
the highest priority becomes the active controller, and ID assignment is determined by the sequence in
which user physically connects the units. The example used below is 12 units to form a linear stack
using stack trunks.
Steps
Manual stack formation:
• Configure default-ports 1/2/1 1/2/3, stack trunks, on all the units.
• Configure highest priority on an intended active controller.
• Configure second highest priority on an intended standby controller.
• Configure 'stack suggested-id' on the intended member units.
• Configure 'stack enable' on all the units and connect the units using stack ports.
