Migrating a Linear Stack to the Campus Fabric Domain

Migrating from a Linear Stack to Campus Fabric

From Top

Use Case 1: Migrating an existing linear stack to PEs in a linear topology

Use Case 2: Migrating an existing linear stack to PEs in a ring topology

Procedure Summary

  1. The CB and the existing stack must be properly cabled.

  2. The existing linear stack can be cabled to deploy either a linear PE topology or a ring PE topology.

  3. On the active controller of the stack to be converted to PEs, erase the startup configuration and reload.

  4. On the CB, run the SPX interactive-setup utility for this deployment scenario.

  5. Default PE IDs are displayed, and you are given the opportunity to accept the default IDs or change them.

  6. The discovered units reload, and the stack units become PE units in the Campus Fabric domain.

  7. Once the topology is active, verify the CSP operational state using the show spx csp all command, and confirm that the handshake is complete. If there is a ring in the topology, verify the ring operational state using the show spx ring all command.

Note: Zero-touch or SPX interactive-setup works only if you erase the startup configuration on the existing stack units before attempting to convert them to PE units.

Illustration Topology

A two-unit ICX 7450 linear stack is cabled to the CB, and the stack units need to be converted to PE units.

  • Existing stacking links between the stack units: 1/3/1 - 2/3/1.

  • Stack unit 1: Port 1/2/1 is connected to CB port 2/1/4.

  • Stack unit 2: Port 1/2/1 is connected to CB port 1/1/3.

  1. Once the units are properly cabled to the CB, erase the startup configuration and reload the stack.
  2. Run the SPX interactive-setup utility on the CB. The discovered topology is displayed, and you are prompted to accept or change default PE ID assignments.
  3. Once you confirm the topology with selected PE IDs, the units reload and join the Campus Fabric domain.

    Note: Although you can also migrate a linear stack with the zero-touch utility, Ruckus recommends using SPX interactive-setup.
