auto-configure upperInterfaceType [ lockout-time { minValue maxValue | none } ]

no auto-configure upperInterfaceType [ lockout-time ]

Release Information

Command introduced before JunosE Release 7.1.0.


Specifies the type(s) of dynamic encapsulations that are accepted or detected by the static ATM 1483 interface. Optionally, specifies the lockout time range for the encapsulation type. You can enter this command repeatedly in Subinterface Configuration mode to support multiple dynamic interface types. The no version terminates detection of the specified encapsulation type or, if the lockout-time keyword is specified, restores the lockout time range to its default values.

Encapsulation type lockout is performed on a per-encapsulation-type basis for each subinterface. An encapsulation type not configured for autodetection with this command is automatically locked out. The lockout temporarily prevents the static ATM 1483 subinterface from detecting, accepting, and creating the encapsulation type until the lockout time expires.


  • Encapsulation type lockout is available for bridged Ethernet, IP, PPP, and PPPoE encapsulation types.
  • Disabling lockout can result in undesirable CPU loading; we recommend that you not disable lockout for general use. At a minimum, use the default lockout time.
