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

.

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,

DENG Hui
