Protecting a unit from being discovered

The spx zero-touch-deny command can be configured on a traditional stack member or standalone device that is connected to non-SPX ports to prevent the device from being converted to a PE unit accidentally.

Follow these steps to prevent an ICX 7150, ICX 7250, or ICX 7450 device from being discovered and converted by the zero-touch or interactive-setup utility.

Note: Use the no form of the command to again make the device available for zero-touch configuration or interactive-setup. The zero-touch-enable or the spx pe-enable command also removes the spx zero-touch-deny setting when entered on the device.
  1. Enter global configuration mode. 
    device# configure terminal
  2. Enter the spx zero-touch-deny command. 
    device(config)# spx zero-touch-deny

The following example protects an ICX 7450 from being discovered by a CB unit when the zero-touch utility or SPX interactive-setup utility is run.
