    DESCRIPTION
            "A unique value, greater than zero, for each
            character port in the managed system.  It is
            recommended that values are assigned contiguously
            starting from 1.  The value for each interface sub-
            layer must remain constant at least from one re-
            initialization of the entity's network management
            system to the next re-initialization.

            In a system where the character ports are attached
            to hardware represented by an ifIndex, it is
            conventional, but not required, to make the
            character port index equal to the corresponding
            ifIndex."

    DESCRIPTION
        "A reference to hardware MIB definitions specific to
        a physical port's external connector.  For example,
        if the connector is RS-232, then the value of this
        object refers to a MIB sub-tree defining objects
        specific to RS-232.  If an agent is not configured

        state, both hardware and software, disconnecting all
        the port's existing sessions.  In response to a
        get-request or get-next-request, the agent always

    STATUS current
    DESCRIPTION
        "The port's desired state, independent of flow
        control.  'enabled' indicates that the port is
        allowed to pass characters and form new sessions.
        'disabled' indicates that the port is allowed to
        pass characters but not form new sessions.  'off'
        indicates that the port is not allowed to pass
        characters or have any sessions. 'maintenance'
        indicates a maintenance mode, exclusive of normal
        operation, such as running a test.

        'enabled' corresponds to ifAdminStatus 'up'.
        'disabled' and 'off' correspond to ifAdminStatus

    DESCRIPTION
        "The port's actual, operational state, independent
        of flow control.  'up' indicates able to function
        normally.  'down' indicates inability to function
        for administrative or operational reasons.
        'maintenance' indicates a maintenance mode,
        exclusive of normal operation, such as running a
        test.  'absent' indicates that port hardware is not
        present.  'active' indicates up with a user present
        (e.g. logged in).

        'up' and 'active' correspond to ifOperStatus 'up'.
        'down' and 'absent' correspond to ifOperStatus
        'down'.  'maintenance' corresponds to ifOperStatus
        'test'."
