[ipcdn] Comments on draft-ietf-ipcdn-pktc-mtamib-07 during the IETF-64 meeting

["Eugene Nechamkin" <enechamkin at broadcom.com>]

 

During the presentation of the draft-ietf-ipcdn-pktc-mtamib-07 at IETF-64 meeting, there were the following comments made on the presented material:

 

    - the max length of the "pktcMtaDevRealmOrgName" currently defined as being 255 does not correspond to the actual number of octets the MIB object may contain which is calculated as max number of UTF-8 characters (64) each of which may consist of up to 6 octets.

    - the value of the MIB object should not include the prefix 'O=' in the Organization Name.

 

The current definition of the "pktcMtaDevRealmOrgName" in the draft-07 is as follows:

 

   pktcMtaDevRealmOrgName  OBJECT-TYPE
       SYNTAX      SnmpAdminString(SIZE (1..255))
       MAX-ACCESS  read-create
       STATUS      current
       DESCRIPTION
           " This object contains the X.500 organization name attribute 
             as defined in the subject name of the service provider 
             certificate. The value of the organization name includes
             the prefix 'O='."
       REFERENCE
           " PacketCable Security Specification."
       ::= { pktcMtaDevRealmEntry 5 }

 

 

To address these two comments, co-authors are proposing the following:

 

1. Add the following to the IMPORTS section of the MTA MIB:

 

    LongUtf8String 

            FROM SYSAPPL-MIB                 -- [RFC2287]

 

2. Modify the definition of the pktcMtaDevRealmOrgName to be the following:

 

 

pktcMtaDevRealmOrgName OBJECT-TYPE

    SYNTAX LongUtf8String

         ^^^^^^^^^^^

    MAX-ACCESS read-create

    STATUS current

    DESCRIPTION

        " This object contains the X.500 organization name attribute

        as defined in the subject name of the service provider

        X.509 certificate."

    REFERENCE

        " PacketCable Security Specification."

    ::= { pktcMtaDevRealmEntry 5 }

 

3. Add the following compliance statement to the MTA MIB compliance section:

 

    OBJECT pktcMtaDevRealmOrgName

    SYNTAX LongUtf8String (SIZE (1..384))

    DESCRIPTION

        " Compliant devices are only required to support

        pktcMtaDevRealmOrgName values of 64 UTF-8 encoded

        characters.

        The Organization Name of the X.509 certificate can

        contain up to 64 UTF-8 encoded characters as

        specified in RFC 2459.

        Given that, in UTF-8, characters are encoded using

        sequences of 1 to 6 octets (RFC 2279), compliant

        devices must support a maximum size of 384 octets for

        pktcMtaDevRealmOrgName."

 

 

Please feel free to provide comments on proposed modifications.

 

Regards,

 

Eugene Nechamkin.
