    enable  [node node-id] xot sap sap-name

    Enables a Service Access Point (SAP) entity of the X.25 Over
    TCP/IP (XOT) module.  The sap-name is a simple name which
    unqiuely identifies a particular SAP instance.

    Before enabling a SAP entity, you should check the local ip
    addresses of any existing SAP entities.  The local ip address
    of 0.0.0.0 specifies that the SAP may listen on any available
    IP interface.  This local ip address of 0.0.0.0 should only
    be specified if a single SAP is in use.

    Example:

    show xot sap * -            ! To see what ip interfaces the
      local ip address, state   !   existing SAPs listen to.
    enable xot sap sap-1
