Migrating a Three-Unit Ring Stack
- After correctly cabling the stack, erase the startup configuration and reload.
- Run the SPX interactive-setup utility on the CB to display the discovered topology.
- Once you confirm the topology with the selected PE IDs, the units reload and join
the Campus Fabric domain.
Select the topology to be added to the Campus Fabric domain and, if necessary, change the PE IDs assigned by default.
In a three-unit stack where all units are selected, there is only one link to remove.
If you want to create a ring of only two units, you do not need to remove any link. You simply select two units, and type 0 when prompted to remove the third unit.
- Once you confirm your selections, the new units reload and join the Campus Fabric
domain as PE units.
spx interactive-setup You can abort spx interactive-setup at any stage by <ctrl-c> 0: quit 1: change PE IDs 2: discover and convert new units (no startup-config flash) to PEs 3: discover and convert existing/new standalone units to PEs Please type your selection: 2 Probing topology to find new units...

You are prompted for your selections.
In the following example, only two units are added.
chain #0: Do you want to select this chain?(enter 'y' or 'n'): y New units form a ring. If you want to select all units, you must remove a link. Type the link to be removed: 0: no, 1: (#1 2/3 -- #3 2/2) (default: 0): 0 option 1 works great. option 0 takes 2 units as such. If 1/’2/3 ==== 3/2/2 s excluded (option 1) then 3 U ring results If 1/2/3 ==32/2/ is included a 2unit ring results. #1: icx7450-48-port-management CC4E.248E.2F90, type an ID (No: 0, default: 19): #2: icx7450-48f-sf-port-management CC4E.246D.10B8, type an ID (No: 0, default: 18): 2 unit(s) selected: #1: ID=19, #2: ID=18, 1 unit(s) not selected: #3, #1 #2 +----+ +----+ 2/3/3==3/1| 19 |2/1--2/1| 18 | +----+ +----+ Will produce the above topology.
