            The enumeration 'chasIdEntPhysicalAlias(1)' represents a

            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.

            a chassis identifier based on the value of entPhysicalAlias

            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.

            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

            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

            restored after a re-initialization of the management

    STATUS      current

    DESCRIPTION

            "This object specifies the desired time interval for which

            an agent will maintain dynamic ptopoConnEntries.

            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
