            "This TC describes the source of a chassis identifier.

            The enumeration 'chasIdEntPhysicalAlias(1)' represents a
            chassis identifier based on the value of entPhysicalAlias
            for a chassis component (i.e., an entPhysicalClass value of
            'chassis(3)').

            The enumeration 'chasIdIfAlias(2)' represents a chassis
            identifier based on the value of ifAlias for an interface
            on the containing chassis.

            The enumeration 'chasIdPortEntPhysicalAlias(3)' represents
            a chassis identifier based on the value of entPhysicalAlias
            for a port or backplane component (i.e., entPhysicalClass
            value of 'port(10)' or 'backplane(4)'), within the
            containing chassis.

            The enumeration 'chasIdMacAddress(4)' represents a chassis
            identifier based on the value of a unicast source MAC
            address (encoded in network byte order and IEEE 802.3
            canonical bit order), of a port on the containing chassis.

            The enumeration 'chasIdPtopoGenAddr(5)' represents a
            chassis identifier based on a network address, associated
            with a particular chassis.  The encoded address is actually
            composed of two fields.  The first field is a single octet,
            representing the IANA AddressFamilyNumbers value for the
            specific address type, and the second field is the
            PtopoGenAddr address value."

            If this object has a value of zero, then no
            ptopoConfigChange notifications will be transmitted by the
            agent.

            If this object has a non-zero value, then the agent must not
            generate more than one ptopoConfigChange trap-event in the
            indicated period, where a 'trap-event' is the transmission
            of a single notification PDU type to a list of notification
            destinations.  If additional configuration changes occur
            within the indicated throttling period, then these trap-
            events must be suppressed by the agent. An NMS should
            periodically check the value of ptopoLastChangeTime to
            detect any missed ptopoConfigChange trap-events, e.g. due to
            throttling or transmission loss.


            If notification transmission is enabled, the suggested
            default throttling period is 60 seconds, but transmission
            should be disabled by default.

            If the agent is capable of storing non-volatile
            configuration, then the value of this object must be

            After the specified number of seconds since the last time an
            entry was verified, in the absence of new verification
            (e.g., receipt of a topology protocol message), the agent
            shall remove the entry.  Note that entries may not always be
            removed immediately, but may possibly be removed at periodic
            garbage collection intervals.
            This object only affects dynamic ptopoConnEntries, i.e.  for
            which ptopoConnIsStatic equals 'false(2)'. Static entries
            are not aged out.

            Note that dynamic ptopoConnEntries may also be removed by
            the agent due to the expired timeliness of learned topology
            information (e.g., timeliness interval for a remote port
            expires).  The actual age-out interval for a given entry is
            defined by the following formula:

              age-out-time =
                min(ptopoConfigMaxHoldTime, <entry-specific hold-time>)

            where <entry-specific hold-time> is determined by the
