Last Call Review of draft-perrault-behave-natv2-mib-03

Hi,

I have reviewed this document as part of the Operational directorate's ongoing
effort to review all IETF documents being processed by the IESG. These comments
were written with the intent of improving the operational aspects of the IETF
drafts. Comments that are not addressed in last call may be included in AD
reviews during the IESG review. Document editors and WG chairs should treat
these comments just like any other last call comments.

This Standards Track document defines a new version of NATV2-MIB for monitoring
the NAT devices. It is intended to replace module NAT-MIB (RFC 4008). However,
deprecating all objects in NAT-MIB (v1) is by a companion document
draft-perrault-behave-deprecate-nat-mib-v1. This document is well written.
While I am not a MIB expert, my review does not include the detailed design of
MIB objects. This document does require another review by MIB expertise or MIB
doctor.

I have some minor comments as follow:

1)      On page 31, as it defined
natv2SubscriberThresholdPortMapEntriesHigh OBJECT-TYPE
       SYNTAX Unsigned32
       MAX-ACCESS read-write
       STATUS current
       DESCRIPTION
           "Notification threshold for total number of port mappings
            active for this subscriber. Whenever
            natv2SubscriberPortMapEntries is updated, if it equals or
            exceeds natv2SubscriberThresholdPortMapEntriesHigh, the
            notification
            natv2NotificationSubscriberPortMappingEntriesHigh is
            triggered, unless the notification is disabled by setting
            the threshold to 0. Reporting is subject to the minimum
            inter-notification interval given by
            natv2SubscriberNotificationInterval. If multiple
            notifications are triggered during one interval, the agent
            MUST report only the one containing the highest value of
            natv2SubscriberPortMapEntries and discard the others."
       DEFVAL
            { 0 }
       ::= { natv2SubscriberEntry 16 }

It needs a sentence to describe that the threshold is default to set 0.

2)      On page 55, it is missing the definition of the natv2PoolEntry 13. The
continuous numbers jumped from 12 to 14.

3)      On page 57, why not to define the natv2PoolRange objects into the
natv2PoolTable? These objects should be part of the natv2Pool objects.

Best regards,

Sheng
