Zero-touch Configuration

The zero-touch utility can be used to discover and deploy new PE units without user intervention when the new units are presented in a valid configuration.

Use the zero-touch-enable command available under spx configure to enable the zero-touch utility. To identify new PE candidates, zero-touch probe packets are transmitted over CB SPX ports, SPX LAGs, the non-base-module ports of edge PE units, and user-configured zero-touch candidate ports.

Note: The first time you enable zero-touch configuration, the system sends a zero-touch probe within 60 seconds. If a CB port comes up or goes down, or if a port specified in the zero-touch-ports configuration or a CB SPX port or LAG with no connection becomes active, a zero-touch probe is also triggered within a minute. Otherwise, a probe is sent every three minutes.
Note: If a port is already up, adding it as an SPX port, adding it to an SPX LAG, or configuring it as a zero-touch port does not trigger the next zero-touch probe within 60 seconds.
Note: RUCKUS recommends disabling zero-touch provisioning once PE discovery is complete.

When PE candidates are discovered in a valid topology, zero-touch candidate ports are converted to CB SPX ports or CB SPX LAGs so that the new PE units can join the Campus Fabric domain. The system displays a message about the new CB SPX ports and LAGs and prompts the user to execute the write memory command to save the new domain configuration.

You must configure the zero-touch candidate ports using the zero-touch-ports command before probe packets can be transmitted over them. Zero-touch ports can only be used to discover new PE units, not to modify existing SPX ports or LAGs. For information on configuring zero-touch-ports, refer to Using zero-touch to add PE units.

Topologies that Support Zero-touch Configuration

The zero-touch utility works only for supported topologies. When the utility encounters an invalid topology, it displays a warning message, in which case you may opt to run the interactive-setup utility instead. The interactive-setup utility can be used for a broader range of topologies and allows the user to select PE candidates interactively for inclusion in the Campus Fabric domain. For more information on the interactive-setup utility refer to SPX interactive-setup.

The zero-touch utility can discover and automatically configure clean ICX 7150, ICX 7250, or ICX 7450 units as new PEs when they occur in one of the topologies covered in Valid topologies.

Additional Zero-touch Considerations

  • The system checks the ports in any zero-touch-ports range you configure and allows the configuration only if all ports in the range are valid. None of the ports in the range may contain configuration.
  • Once new PEs have been detected and added, the zero-touch-ports configuration should be removed to free the ports for other uses.
  • The zero-touch utility automatically asigns PE IDs based on spx pe-id configuration or internal algorithms.
  • The zero-touch utility automatically generates SPX ports or LAGs for the PE units.
  • The end unit in a chain of new PE units is assigned only one SPX port or LAG.
