RE: Re: Re: MIB Dr. Review ofdraft-ietf-vrrp-unified-mib-05.txt

Thanks Joan,
I will remove the not-accessible (index) objects from the conformance
section (this will remove the level 3 error)
and will add text to the description (This will take care of the level 5
warning below)

Thanks Again to you and Bert for all the help.

Thanks,
Kalyan

Hi Kaylan,

As Bert points out,  in this specific case you should ignore the warning

about the length of the subIds exceeding 128.

vrrpAssociatedIpAddr  OBJECT-TYPE
SYNTAX  InetAddress (SIZE(0|4|16))
MAX-ACCESS not-accessible

Also, adding to the DESCRIPTION clause is fine.

You do not need to include this INDEX in the conformance section because
it is an INDEX.  

Other Objects (which have MAX-ACCESS other than not-accessible) should
be
in the Conformance section.

Thanks,
  Joan
