    Default: No passwords  Value: Set of hex-string

    Set of passwords that are valid in level 1 LSPs, PSNPs, and CSNPs
    when simple authentication is in use. You cannot use the show
    command to display the value of this attribute.

    Password to be sent in level 1 LSPs, PSNPs, and CSNPs when simple
    authentication is in use. You cannot use the show command to

 o  autonomous system number

    Support: IP
    Default: 0             Value: 0-65535

    Autonomous system number of the local system. This characteristic
    is supported only if the value of the routing protocols supported

    from the characteristic manual network entity titles and the
    selectors supplied by the transport protocol module (NSP and/or
    OSI transport).

    The DNA address format attribute controls only the interpretation
    of address structuring and no longer controls autoconfiguration.
    To control autoconfiguration, you need to use the manual network entity
    titles attribute by manually adding or removing NETs.

    when simple authentication is in use. You cannot use the show
    command to display the value of this attribute.

 o  domain send password

    Support: L2,IP
    Default: No password   Value: Hex-string

 o  routing mode

    Support: End
    Default: Integrated propogation      Value: Segregated or Integrated

    routing mode is set to Segregated, data being transmitted to
    Phase IV destination addresses is sent in Phase IV format packets,
    to the adjacent Phase IV router, if available. In Integrated mode,
    data is sent to Phase V (OSI) router adjacencies in CLNP packets,
    if possible.

    This characteristic can only be set when Routing is disabled.
    For example, to switch to segregated mode from the default:

        NCL> disable routing

        NCL> enable routing
        NCL> enable routing circuit *

    include the following protocol pairs:

    EGP to IS-IS   IS-IS to RIP
    EGP to RIP     RIP to EGP
    IS-IS to EGP

    If a particular value is not present in the set, routes are
    not propagated between those two protocols in that direction.
    This characteristic is supported only if the routing protocols
    supported characteristic includes either of the EGP or RIP
    routing protocols.

 o  routing mode

    Support: End
    Default: Integrated                   Value: Segregated or Integrated

    Determines the behavior of the forwarding algorithm. When the routing
    mode is set to Segregated, data being transmitted to Phase IV
    destination addresses is sent in Phase IV format packets, to the
    adjacent Phase IV router, if available. In Integrated mode, data is
    sent to Phase V (OSI) router adjacencies in CLNP packets, if possible.

    This characteristic can only be set when Routing is disabled.
    For example, to switch to segregated mode from the default:

       NCL> disable routing
       NCL> set routing routing mode = segregated
       NCL> enable routing
       NCL> enable routing circuit *

    Default: 100           Value: 1-65535

    packets sent by this node.

    Default: 35            Value: 1-255

    Specifies the value to be placed in the time to live field of
    originating IP packets. This value should be greater than the
    maximum number of hops in any path on the network.

    attribute values using the set command.

                                   NOTE
