Re: [IPFIX] MPLS IEs in IANA's IP Flow Information Export (IPFIX) Entities registry

Hi Andrew,
you're right, the RFC 5462 changed the interpretation of this field as well (section 2 Details of Change):
2.1<http://tools.ietf.org/html/rfc5462#section-2.1>.  RFC 3032<http://tools.ietf.org/html/rfc3032>


   RFC 3032<http://tools.ietf.org/html/rfc3032> states on page 4:

      3.  Experimental Use

      This three-bit field is reserved for experimental use.

   This paragraph is now changed to:

      3.  Traffic Class (TC) field

      This three-bit field is used to carry traffic class information,
      and the change of the name is applicable to all places it occurs
      in IETF RFCs and other IETF documents.

                Regards,
                                Greg

Hi Greg,

Dear All,
in several places of describing MPLS Label element IEs the registry still refers to the EXP field even though the RFC 5462 updated RFC 3032 and renamed it "Traffic Class" (TC). Below is the list of IEs that may benefit from updating Description and Reference information:

*         mplsTopLabelStackSection

*         mplsTopLabelStackSection2

*         mplsTopLabelStackSection3

*         mplsTopLabelStackSection4

*         mplsTopLabelStackSection5

*         mplsTopLabelStackSection6

*         mplsTopLabelStackSection7

*         mplsTopLabelStackSection8

*         mplsTopLabelStackSection9

*         mplsTopLabelStackSection10

*         mplsTopLabelExp (should this be deprecated and mplsTopLabelTc be created instead?)

*         postMplsTopLabelExp (should this be deprecated and postMplsTopLabelTc be created instead?)

Did 5462 change just the name from Exp to TC or did the interpretation of the bits change?
