Zero-touch 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.
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.
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-portsrange 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-portsconfiguration should be removed to free the ports for other uses. - The zero-touch utility automatically asigns PE IDs based on
spx pe-idconfiguration 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.
