Bert,

It is my understanding that the "SHOULD" in the quoted text directs us to put the MODULE-IDENTITY value under the mgmt subtree, as opposed to the experimental one.

It does not specify the exact location under the mgmt, saying (for example) that it could be under mgmt/mib-2, or mgmt/mib-2/transmission or anything else under mgmt/ for that matter.

I don't see any deviation from that recommendation in the proposed assignments:

 

mgmt/mib-2/gBondMIB                          - this value is assigned by IANA

mgmt/mib-2/gBondMIB/gBondAtmMIB    - this value is assigned by IANA

mgmt/mib-2/gBondMIB/gBondEthMIB     - this value is assigned by IANA

mgmt/mib-2/gBondMIB/gBondTdimMIB   - this value is assigned by IANA

 

That is - all new MODULE-IDENTITY OIDs are under the mgmt subtree and assigned by IANA.

 

I will explicitly specify in the IANA considerations section how and when the new MODULE-IDENTITY values under gBondMIB should be assigned.

Regards,

-E.

The "SHOULD" in the quoted text means that that is where assignments should be made

and that you must have a STRONG and WELL JUSTIFIED reason to deviate.

 

And again, if you decide to keep the gBond tree/branch, then you MUST also add more

to the IANA considerations and explain how and when IAN can assign new values under

that branch. Do they require standard track documents?

 

Or can I as an individual define gBondBWijnenMIB or some such?

Or can alcatel-lucent (just as an example) define an enterprise specific

gBondALUMIB module and have it registered under gBond??

 

I guess the latter two are not intended. So IANA must know and understand that.

And IANA will want/need an expert to help them decide (they are not MIB experts

nor experts in all sorts of possible gBond technologies.

 

Again, your AD will decide. But you will need good arguments, and a well written

IANA considerations section that answers all of the above questions (and possibly

many more similar questions). Just trying to help you understand why RFC4181

does NOT RECOMMEND this practice.

Menachem,

 

Let's look at the relevant paragraph from RFC 4181 again:

- The value assigned to the MODULE-IDENTITY descriptor MUST be unique and (for IETF standards-track MIB modules) SHOULD reside under the mgmt subtree [RFC2578]. Most often it will be an IANA-assigned value directly under mib-2 [RFC2578], although for media-specific MIB modules that extend the IF-MIB [RFC2863] it is customary to use an IANA-assigned value under transmission [RFC2578]. In the past, some IETF working groups have made their own assignments from subtrees delegated to them by IANA, but that practice has proven problematic and is NOT RECOMMENDED.The words "most often" and "customary" can hardly be considered as recommendations,
so there's no hard requirement for the location of the MODULE-IDENTITY OIDs, i.e. it does not
have to be placed directly under mib-2.The NOT RECOMMENDED practice is a non-IANA assignment of MODULE-IDENTITY
descriptors under a delegated subtree.Therefore I suggest we keep the existing MIB hierarchy, but instead
of assigning the 1st 3 module OIDs ourselves, we ask IANA to assign
them to be completely compliant to the spirit of RFC 4181, that is,
the MODULE-IDENTITY for each of the G.Bond schemes would be declared
as:gBondAtmMIB MODULE-IDENTITY ... ::= { gBondMIB XXX }gBondEthMIB MODULE-IDENTITY ... ::= { gBondMIB YYY }gBondTdimMIB MODULE-IDENTITY ... ::= { gBondMIB ZZZ }with an editor's note asking IANA to allocate the XXX, YYY and ZZZ numbers.

Regards,
-E.

    That's fine, but Dan has requested a stong argument if we intend to go down this path, which is NOT RECOMMENDED by RFC 4181.

 

"In case the WG intents to require such a policy I suggest that you prepare a strong argument that shows what problems would be created by following RFC 4181." (Dan's email 16/7/07).

 

    What are the problems that would incur if we follow RFC 4181?  (Please explain this on the mailing list)

Hi Naren,

 

I agree. Putting the technology specific MIBs under the common MIB is preferred.

Moti, Ed,

 

What is your opinion? In my view, putting them all under mib-2 might be confusing. I prefer the technology specific MIBs to be grouped under the common MIB.

 

Thanks,

naren

Hello,

 

    I haven't seen any response on this issue.

 

    Naren do you still wish to put the specific MIB modules under the common MIB?

 

As Bert pointed out, if we do this there will be a need to write an additional RFC explaining the OID

assignments (as was done by RMONMIB WG RFC 3737). In addition, one or two people will always need to be available to advise the IANA should new OID assignments be required in the future. If MIB modules are placed under MIB-II then

the IANA provides this service.

 

    Thoughts?

 

    Best Regards,

    Menachem

Hi,

 

    Looking at the minutes from IETF-68, this matter was intended to be raised with the MIB Doctors as a question. So have the editors had second thoughts.

 

    I would like to see where everyone on the WG stands on this issue.

 

    Best Regards,

Yes. Frankly speaking, it is not clear to me why would the WG adopt a policy of assigning root OIDs that is NOT RECOMMENDED by RFC 4181. In case the WG intents to require such a policy I suggest that you prepare a strong argument that shows what problems would be created by following RFC 4181.

I guess, this is up to Dan (AD) to decide.

If you want to keep your own tree under a common gbond tree/branch,

then I suggest you would need a document aka RFC3737 and then

Let IAN do the registration.

Subject: Positioning of gBondATM, Eth and TDIM MIB modules

Hi,

In IETF-68, Bert had mentioned that gBondATM, Eth and TDIM should be under mib-2 in addition to the gBond MIB modules. This was according to the RFC4181 guideline on MODULE-IDENTITY (page number 13):

    "The value assigned to the MODULE-IDENTITY descriptor MUST be unique
     and (for IETF standards-track MIB modules) SHOULD reside under the
     mgmt subtree [RFC2578].  Most often it will be an IANA-assigned
     value directly under mib-2 [RFC2578], although for media-specific
     MIB modules that extend the IF-MIB [RFC2863] it is customary to use
     an IANA-assigned value under transmission [RFC2578].  In the past,
     some IETF working groups have made their own assignments from
     subtrees delegated to them by IANA, but that practice has proven
     problematic and is NOT RECOMMENDED."

However, in the design of gBond MIBs we chose to have the ATM, Eth and TDIM specific MIB modules under gBond (common) MIB. The reason for such a design was the following:

a) gBond common MIB module cannot exist on its own; for any system to implement bonding MIB, it would need to implement the common mib as well of the specific technology that it intends to support.

b) It does not make sense to put managed objects for all technologies into one MIB module, as a system might need to implement managed objects for only a subset of the technologies viz. ATM, Eth and TDIM.

In the particular case of the gBond MIB, the editors' view is that there exist valid reasons for placing the technology specific MIB modules under gBond MIB subtree.

Therefore, I would like to request the working group members to comment on this point, so that the case is carefully considered.

regards,
Naren
