The "no" Form of a Command


The "no" form of a command can take the following meanings depending on the context:

  • Sets the parameter back to its default value. For example, to set the parameter, signaling-mode, back to its default value:

    bti7800(config-interface-10ge:1/3/1/1)# signaling-mode ?
    bti7800(config-interface-10ge:1/3/1/1)# no signaling-mode
    bti7800(config-interface-10ge:1/3/1/1)# signaling-mode ?
  • Negates a command. For example, to enable the airfilterAbsence alarm:

    bti7800(config)# no conditions settings airfilterAbsense disable
  • Deletes a provisioned entity. For example, to delete an interface:

    bti7800(config)# no interface 10ge:1/3/1/2

Note that the "no" form of the same command might take on different meanings depending on the parameters you use in the command.

  • This sets the parameter back to its default value:

    bti7800(config)# no system auto-warm-boot
  • This enables the option:

    bti7800(config)# no system auto-warm-boot disabled
