Quoting Miguel Garcia:
|  I have a comment with respect the normative statements that appear in 
|  towards the end of Section 4, using the terms "RECOMMENDED" and "NOT 
|  RECOMMENDED". The text I refer to is this one:
|  
|      Further, deployment of SNMP versions prior to SNMPv3 is NOT
|      RECOMMENDED.  Instead, it is RECOMMENDED to deploy SNMPv3 and to
|      enable cryptographic security.
|  
|  I think the text is speaking about *deployment*, not about 
|  *implementation* of a feature. RFC 2119 only considers implementation, 
|  but not deployment issues, so in my opinion the upper case should not 
|  apply. Additionally, please notice that RFC 2119 does not define the 
|  term "NOT RECOMMENDED", so, it certainly has little meaning in uppercase.
This text is from a boilerplate, which is recommended for use by 
    "Security Guidelines for IETF MIB Modules" on
     http://www.ops.ietf.org/mib-security.html
     (suggested in BCP 111, RFC 4181, App. A (4))
The text has been copied verbatim, and the same paragraph appears in other
(MIB-related) RFCs as well, e.g.
        * RFC 3584, sec. 8
        * RFC 4069, sec. 6
        * RFC 4044, sec. 10
        * RFC 4318, sec. 8

I can see your point but it creates a conflict with regard to the suggestions
of Appendix A in RFC 4181. Please let us know if we can improve this or whether
this is a more general issue regarding security statements.

Best regards
Gerrit Renker
