Hi, 

I am an assigned INT directorate reviewer for draft-ietf-softwire-dslite-mib-11. These comments were written primarily for the benefit of the Internet Area Directors. 

Document editors and shepherd(s) should treat these comments just like they would treat comments from any other IETF contributors and resolve them along with any other 

Last Call comments that have been received. For more details on the INT Directorate, see 

http://www.ietf.org/iesg/directorate/intarea.html

.

This document defines MIB objects to manage DS-Lite solutions, and targets the Standards Track.

Please find some minor review comments:

1) As the coordination with the NATv2-MIB (the draft has not published), the MIB checker reports several errors in this DS-Lite MIB.

2) In section 6.1.1,  “Because some objects defined in the IP Tunnel MIB are not read-write and read-only, a few new objects are defined in DS- Lite MIB.” What is the “read-write” and “read-only”? If it is a special meaning words in MIB, it need a quotation mark here.

3) In page 8, 

“dsliteTunnelAddressType OBJECT-TYPE

SYNTAX InetAddressType

MAX-ACCESS not-accessible

STATUS current

DESCRIPTION

" This object MUST be set to the value of ipv6(2).

It describes the address type of the IPv4-in-IPv6

tunnel initiator and endpoint."

::= { dsliteTunnelEntry 1 }”

There’s no scenario requiring ipv6z(4)?  It needs a REFERENCE to RFC 4001 in this object definition.

4) In page 10, DsliteNATBindEntry: I think dsliteNATBindMappingExtAddressType and dsliteNATBindMappingIntAddressType should just be dsliteNATBindMappingAddressType and apply to both. If all address objects in the row are of the same type, you only need one type object.

5) In page 11, it needs a REFERENCE to RFC 4001 in the definition of dsliteNATBindMappingExtPort.

6) In page 12, it need some description to describe “endpointIndependent, addressDependent, addressAndPortDependent” in more detail in the DESCRIPTION of dsliteNATBindMappingMapBehavior. 

 The same comments to the “arbitrary, paired” in dsliteMATBindMappingAddressPooling. A REFERENCE is also needed.

7) In page 14, it needs to define a DEFVAL value for dsliteAFTRAlarmConnectionNumber.

8) Whether dsliteStatisticSubscriberIdex is enough or direct to get subscribers' information? 

9) I am not very sure what is dsliteStatisticIpv6Session mean? As for IPv6 traffic, there seems no mapping. 

10)Whether there has requirement to support multiple instances in DS-Lite? 

Best regards,
